# Senior ARCore / UWB Indoor Positioning Engineer — Complete Existing Android AR Navigation System

## Project Overview

We are looking for a highly experienced engineer specializing in augmented reality, indoor positioning, computer vision, and sensor fusion to complete an existing Android-based spatial navigation system.

**This is an existing, partially functional project — not a new development project.**

The core application, positioning infrastructure, and room-mapping components already exist. We need an engineer who can diagnose the remaining integration problems, implement reliable solutions, and deliver a fully tested working system.

Our priority is efficient completion, preservation of existing functionality, and measurable real-world performance.

## Existing Technology

- Native Android application
- Google ARCore
- Immersal visual positioning/localization
- Ultra-Wideband (UWB) indoor positioning
- Four fixed UWB anchors
- Existing live positioning measurements
- Room mapping, calibration, and coordinate management
- Existing backend and application integration

## Main Engineering Responsibilities

**1. Automatic Room Recognition and AR Localization**

- Recognize previously mapped indoor environments without repeatedly scanning a printed floor marker.
- Integrate and stabilize ARCore and Immersal localization.
- Establish persistent spatial alignment between the physical room and its digital map.
- Handle tracking loss, camera movement, lighting variations, and automatic relocalization.
- Implement a practical fallback when markerless localization is unavailable.

**2. UWB Positioning and Sensor Fusion**

- Review the existing UWB positioning pipeline and anchor configuration.
- Validate coordinate calculations, anchor geometry, calibration, and measurement consistency.
- Address positioning jitter, outliers, latency, and uncertainty.
- Correctly transform UWB coordinates into the room-map and ARCore coordinate systems.
- Investigate appropriate filtering and sensor-fusion methods.
- Preserve existing functioning UWB measurements.

**3. Real-Time AR Navigation**

- Allow users to select a UWB device and immediately initiate guided navigation.
- Display stable directional arrows and continuously updated distance information.
- Maintain correct navigation guidance while the user walks, turns, or changes camera orientation.
- Handle temporarily unavailable positioning data.
- Recover navigation automatically after interruptions.
- Prevent misleading guidance when tracking confidence is insufficient.

**4. Room Mapping and Calibration Integration**

- Integrate with the existing room-mapping system.
- Preserve saved maps, coordinate references, and calibration information.
- Ensure consistent coordinate alignment after saving, reopening, or re-entering a mapped environment.
- Support reliable operation when room-map validation is incomplete.

**5. Android and Backend Integration**

- Work directly within the existing Android codebase.
- Maintain compatibility with the current backend and positioning infrastructure.
- Handle application lifecycle changes, relevant permissions, device reconnection, and tracking interruptions.
- Avoid unnecessary architectural rewrites or removal of working functionality.
- Deliver reproducible builds and maintainable source code.

**6. Real-World Validation**

The solution must be tested with actual UWB hardware and Android devices, not only simulated data.

Testing should include:

- Stationary and moving UWB targets
- Walking and phone rotation
- Repeated room entry
- Tracking loss and recovery
- UWB signal interruption
- Coordinate stability and repeatability
- Comparison of measured positions against known reference positions
- Regression testing of existing functionality

Performance must be documented with real measurements. We do not expect unsupported accuracy claims.

## Required Experience

- Advanced Android development (Kotlin/Java)
- Google ARCore and spatial coordinate systems
- Indoor positioning, preferably UWB/RTLS
- Computer vision, visual localization, or SLAM
- Sensor fusion and coordinate transformations
- Real-time navigation and tracking
- Debugging and completing existing complex software systems

Experience with Immersal and DW3000-family UWB technology is highly desirable.

## Expected Deliverables

1. Technical assessment of the existing implementation.
2. Documented root causes and implementation plan.
3. Working automatic room localization and recovery.
4. Reliable UWB-to-AR coordinate alignment.
5. Functional real-time AR navigation to selected UWB targets.
6. Complete integration into the existing Android application.
7. Source code, build instructions, and relevant documentation.
8. Real-device validation results and regression-test evidence.

## Engagement and Timeline

We want to complete this project as efficiently as technically possible.

The engagement will begin with a limited paid technical assessment. Implementation will proceed through separately approved milestones with clear acceptance criteria.

The estimated duration is provisional and will be determined after reviewing the existing implementation. We are not offering a permanent position or guaranteeing a fixed number of months.

## Application Requirements

Please answer the following:

1. Have you personally implemented UWB or another indoor positioning technology together with ARCore? Describe the project.
2. How would you align UWB coordinates with ARCore world coordinates?
3. What approach would you use for markerless room recognition and automatic relocalization?
4. Have you worked with Immersal or similar visual positioning technology?
5. Can you provide examples of comparable working systems?
6. Are you comfortable working within an existing Android project rather than rebuilding it?
7. What would you charge for an initial technical assessment, and when could you start?

**We are seeking an engineer capable of delivering a validated working implementation, not a generic AR demonstration, hardware design service, or consultation-only engagement.**

We are looking for an experienced computer-vision engineer to develop a proof-of-concept system for virtual advertising in recorded football broadcast footage.

The initial prototype should replace advertising shown on physical LED perimeter boards with new supplied creative, while keeping the replacement correctly positioned as the broadcast camera moves.

This is an early-stage technical feasibility project. The first version will work with recorded footage rather than a live broadcast feed but we eventually want to get to that.

Initial prototype requirements

Using a short sample of football broadcast footage, the system should:

Identify and track the visible LED perimeter boards.
Replace the existing board content with supplied video or animated graphics.
Maintain correct scale, perspective and positioning during camera movement.
Mask players, officials and other foreground objects when they pass in front of the advertising.
Produce a clean exported 1080p video.
Use automated or semi-automated computer vision rather than manual frame-by-frame editing.
Be capable of being adapted to additional footage and stadium configurations.

The successful freelancer must provide the complete source code, documentation and setup instructions.

Required experience

Applicants should have strong practical experience in several of the following areas:

OpenCV
Python and/or C++
PyTorch, TensorFlow or similar frameworks
Camera calibration
Homography and perspective transformation
Semantic or instance segmentation
Object detection and tracking
Video compositing
FFmpeg or GStreamer
CUDA or GPU optimisation
Real-time or near-real-time video processing

Experience with broadcast graphics, augmented reality, virtual production, sports analytics, Unreal Engine, NDI or SDI workflows would be useful but is not essential.

Initial deliverable

The first paid milestone will involve approximately 30–60 seconds of supplied football footage.

The expected deliverable is:

Replacement of the visible LED advertising.
Stable tracking during camera pan, tilt and zoom.
Foreground masking when players cross the advertising area.
An exported demonstration video.
Complete source code.
Instructions explaining how to run the system with replacement creative.

This is not a video-editing or manual rotoscoping project. We are looking for a technically reusable computer-vision solution.

Potential future work

If the prototype is successful, further work may include:

Longer football broadcasts.
Automated stadium and board calibration.
Virtual 3D advertising carpets.
Support for different stadiums and camera positions.
An operator interface.
GPU optimisation.
Near-live or live video processing.
Multiple regional advertising outputs.

There is potential for a longer-term technical relationship for the right person or team.

Application questions

Please answer the following questions in your proposal:

Describe a relevant project where you anchored graphics or virtual objects to footage from a moving camera.
How would you track the geometry of LED perimeter boards during camera movement?
How would you mask players passing in front of the replacement advertising?
Would you use classical computer vision, machine learning or a combination of both?
How would you minimise manual calibration or rotoscoping?
What processing speed would you expect to achieve at 1080p?
What additional development would be required to make the system operate live?
Which parts of your previous work can you demonstrate on a video call?
Are you personally completing the work, or would any part be subcontracted?

Generic AI proposals will not be considered. Please explain your proposed technical approach and include examples of directly relevant work.

Commercial terms

The project will be structured through fixed-price milestones.

The client must receive:

Ownership of all bespoke source code following payment.
Access to the code throughout development through a client-controlled repository.
A list of all third-party libraries, models and licences.
Full disclosure of any existing proprietary components.
Documentation sufficient for another engineer to run and review the system.

The supplied footage and commercial information must remain confidential and may not be used in portfolios or demonstrations without written permission.

Please include:

Your proposed budget for the initial prototype and full development.
Estimated delivery schedule.
Recommended technology stack.
Any assumptions or technical limitations.

I need a custom virtual camera that can join a Zoom call and replace my face in real time with a chosen subject’s face. Before each meeting I want to load one or more reference photos (or short video clips) of that person; once the call starts, the software should track my head and mouth movements and render a realistic, latency-free face swap that other participants see as my camera feed.

Zoom is the first platform I must support, but I eventually want to point the same virtual camera at Google Meet and Microsoft Teams, so please keep cross-platform thinking in mind. Whatever stack you prefer—OpenCV, MediaPipe, TensorFlow, Unreal’s LiveLink, or your own pipeline—you’ll need to handle live video I/O, facial-landmark tracking, texture blending, and create a signed driver or plugin so the operating system recognises the feed as a standard webcam.

Deliverables
• Desktop application (Windows or macOS) that appears in Zoom as a selectable camera
• Interface to import photos or videos that train/drive the swap model on the fly
• Real-time, high-resolution face replacement that matches lighting and expressions
• Installation package and brief usage guide for non-technical users

When you reply, just show examples of past work that prove you have already built—or heavily contributed to—similar real-time video or AR projects. A short demo clip or repo link is perfect.

Hello, we have developed a pipeline to create scaled human 3D models from an iOS device. We have our own 3DGS, meshing and ARKit scaling solution, however we need help refining the process to match 3rd party system performance. Are you the right person to help? We would love to chat and explore the project. Regards, James

About Cranium Inc. (NOEMA)
Cranium Inc. is building a wearable platform that combines computer vision, AI, and AR/VR. We are building towards a functional prototype and are looking for an experienced engineer to take over technical leadership and carry it forward.

The role
Our current lead engineer is stepping down for health reasons, effective October 31, 2026. You'll take over his work through a structured handoff, supported by NOEMA, our engineering assistant that holds the project context, codebase knowledge, and documentation. From there, you'll own the continued development of the prototype.

What you'll do

-Pick up the existing prototype work and get up to speed quickly through the handoff
-Build and train computer vision detection models that find and classify what the wearable sees in real time, such as people, vehicles, and objects, so the system knows both what is in view and where it is
-Lead development of the computer vision and AI pipelines running on the wearable
-Build and refine AR/VR features and the user-facing experience
-Design and integrate agentic AI capabilities into the platform
-Write production-quality C++ and Python, and make the key architecture decisions
-Document your work and set the technical direction for the next phase

Requirements

-PhD or Master's in Computer Science, Computer Engineering, or a closely related field
-Strong expertise in computer vision (detection, tracking, SLAM, sensor fusion, or similar)
-Proven experience with AI/ML, including agentic AI systems (LLM-based agents, tool use, autonomous workflows)
-Hands-on AR/VR development experience
-Advanced proficiency in C++ and Python
-Able to inherit an existing codebase and deliver independently

Nice to have

-Experience with wearables, embedded or edge devices, or real-time systems
-Familiarity with Unity, Unreal, OpenXR, OpenCV, PyTorch, or TensorRT
-Experience in hardware/software prototyping or at a startup

Timeline
We'd like to start right away so the handoff overlaps with the current lead before October 31, 2026.

I need a focused AR application that lets our manufacturing and maintenance crews pull up 2D technical drawings and blueprints directly on their smart-glasses. The idea is simple: a technician looks at a machine, gives a voice or gesture command, and the relevant plan appears aligned to what they see, ready to zoom, pan, toggle layers, or mark-up while their hands stay free.

Key functions I expect
• Import of common plan formats (PDF, DWG, DXF) and quick cloud sync or local caching for offline areas
• Accurate spatial anchoring so the drawing “sticks” to the equipment even if the wearer moves around it
• Smooth navigation—gesture, voice, or simple controller input—to scroll, zoom, rotate, and switch sheets
• Lightweight annotation: highlight, add notes, then export the updated file back to our server
• Basic user management so only authorised staff access sensitive drawings

Nice-to-have (not essential for the first build) would be the option to expand into live remote support later on.

Please deliver the compiled app, source code, and a short deployment guide for whichever headset SDK you choose (we currently test on HoloLens 2 but are open to Vuzix or similar). I’m happy to provide sample blueprints and run quick usability checks during development.

My restaurant ordering platform is already live with core features coded, yet it still needs a round of deep polishing before it can comfortably scale. Here is what remains:

• Payment flow

Customers must be able to pay the restaurant directly inside the app or website. The underlying codebase is ready for a gateway (Stripe Connect, Square API, or similar), but I need you to wire it end-to-end, handle web-hooks, receipts, and edge-case errors so funds settle straight into each restaurant’s account.

• Kitchen order experience

Orders appear on tablet-based kitchen display screens (iOS and Android). I want the ticket layout, bump/recall actions, and sound/visual alerts tuned the way an experienced line cook expects them. Any latency, mis-sorting, or unclear status colours should be fixed.

• 3D & AR assets

Menu items are stored as .glb files for augmented-reality previews. Optimise load times, ensure correct scene lighting, and test on mainstream AR viewers so models pop up crisply in customers’ kitchens.

• Bug hunting & UX polish

Run through the whole web + mobile stack, squash lingering bugs, tighten API calls, and reduce page/app launch time. I’d like every click path to feel effortless for both diners and staff.

• Final walkthrough

Once the code is stable, walk me through deployment scripts, environment variables, and payment-ops reports so I can run the system confidently without further hand-holding.

Acceptance is simple: payments clear to restaurant accounts without manual intervention, tickets fire correctly on tablets under service load, glb models render in AR with <2 s load, and no critical errors show in the log after a full dinner-rush simulation.

Skills: PHP, Mobile App Development, iPhone, Android, Stripe, Augmented Reality, API Integration, Payment Processing

I've developed a golf green reading app that works in the following way.

1) User uses Lidar to scan the putting green and find changes in elevation (uphill, downhill, and side-hill).
2) User marks the golf ball, walks to the hole (continually scanning) and marks the golf hole
3) This data gets fed into a proprietary "Putt Engine" which I've built. This putt engine reads all the changes in elevation between the ball and the hole and provides the exact spot to aim and the speed to hit the golf ball. When correct, it will map the path of the ball exactly from the ball to the hole.
4) ARKit is used to draw a virtual "aim line" and "putt line" to show the exact path from the ball to the hole

I have attached two examples of what this looks like for reference.
1) "Working Example" file shows what this looks like when it works correctly
2) "Big AR glitch" shows what happens when the AR does not work correctly

I need a developer to help me with the following issues:

1) The AR is very inconsistent. Right now it does not do a good job of staying on the ball or on the hole. Since the user flow involves walking around the hole / green, even after marking the ball or hole there is usually a significant amount of AR drift that takes the line far off of the ball and the hole.

2) There is a consistent issue where the Lidar has a built in bias of reading slope more towards one direction versus the other. Right now this can be fixed with a daily calibration that removes the bias, but this is obviously not ideal, and the bias is not always consistent on a day to day basis.

3) There are sometimes bugs in the Lidar scanning process where it does not collect an accurate scan and will give false readings (picking up shoes, leaves, other golf balls on the green, etc).

4) Finding a more efficient user flow for scanning, marking the ball, and marking the hole (the existing flow is relatively time consuming)

Hopefully this project is of interest to you! If it is, please let me know the following:

1) Anticipated difficulty in solving the AR drift issue mentioned above, and level of confidence that we could fix it
2) Anticipated difficulty in solving the other issues mentioned above (Lidar bias, bugs in Lidar scanning, etc)
3) Estimated time required to solve this
4) Estimated cost required to solve this

Hope we can work together and thank you!

Take a look at the working hours and based on your understanding of the brief let me know your price. I could change the title of the job if needed.

Project: Fixed-price, with milestones to be mutually agreed upon
Location: Remote
Potential: One-off project with possible ongoing collaboration

About IRIS

IRIS Art Tech is my creative practice based in the, UK, working across photography, portraiture, augmented reality (AR), sound and digital storytelling. My work explores identity, memory, belonging and how technology can carry more of a person and their story than a single photograph.

I'm preparing to launch my newly designed website, which establishes the visual identity of IRIS through its colour, typography, tone and personality. I now want a social media presence that feels like an extension of that same creative world.

I'm looking for a talented designer with a strong visual sensibility to help revitalise my feed and create content that is as imaginative and distinctive as the work itself.

The Brief

I'm commissioning 16–20 Instagram-first posts using material from my website and extensive Dropbox library of photography, video, AR footage, project documentation, artist statements and quotes.

Almost everything needed already exists. What I need is someone with the creative eye to find it, recognise its potential and turn it into compelling social content.

You'll independently explore the website and archive, identify the strongest images, lines and stories, and propose what to create. I'm looking for creative initiative and not someone who needs every post conceptualised for them.

The overarching goal is to revitalise my social media feed, build anticipation for the website launch and drive meaningful traffic to the site. I want audiences to explore my projects, experience the AR portraits, discover my services, book portrait sessions, enquire about commissions and collaborations, and sign up for updates.

The content should work both as individual posts and as a cohesive campaign, introducing IRIS to new audiences while giving existing followers new reasons to engage.

Content Mix

The final balance of formats and themes will be agreed upon before work begins. I'm interested in:

Website launch: Visually striking teasers building anticipation, followed by launch announcements inviting audiences into the new website.

Quotes and storytelling: Poignant, thought-provoking lines from the website, artist statements and project writing, brought to life through expressive typography, imagery and motion.

Project showcases: Photography-led posts, carousels and short videos highlighting my artwork, exhibitions and creative projects.

AR in action: Screen recordings, animations or short videos showing portraits coming to life and explaining how audiences can experience them.

Services and commissions: Content introducing my portraiture, photography, AR commissions, creative services, exhibitions and collaborative opportunities, with clear pathways to enquire or book.

Calls to action: Creative prompts encouraging website visits, mailing-list sign-ups, enquiries and opportunities to work together.

Behind the work: Insights into my creative process, artistic philosophy, collaborators and the stories behind the images.

I'd like a considered mix of static graphics, carousels, animated posts, motion graphics and short-form videos. Variety and cohesion are equally important

Creative Direction

Bold. Striking. Animated. Textured. Cool. Contemporary. Unmistakably IRIS.

Think contemporary art direction and experimental editorial design, not conventional corporate social media marketing.

I'm drawn to strong typography, vivid colour, rich textures, unexpected compositions, layered imagery, interesting transitions and movement. The content should feel expressive, playful, culturally aware and sophisticated, without losing the substance of the stories being told.

My website is the primary creative reference. Its typography, colours, visual language and personality should inform the entire collection.

Every post should feel recognisably IRIS, but they shouldn't all look the same.

I don't want generic Canva templates, repetitive layouts, bland promotional graphics or AI-generated imagery. I'm looking for original, visually arresting work that makes people stop scrolling, engage with the content and want to discover more.

Available Materials

You'll receive access to:

My website preview ahead of its public launch announcement

An extensive Dropbox library of photography, video, graphics and creative assets

Existing AR portraits and demonstration footage

Project descriptions, artist statements, written content and quotes

Brand references and guidance where required

I expect you to take creative initiative in exploring these materials while respecting the integrity of the artwork, participants' stories and existing brand identity.

Deliverables

A short creative direction and proposed content plan for approval before full production

16–20 publication-ready social media posts, combining static graphics, carousels, animation and short-form video

Instagram-ready formats, adaptable to other platforms where practical

appropriate website destinations for each post

A proposed publishing sequence covering pre-launch, launch and ongoing promotion

Editable source files for future use

The exact number of posts in each format, including carousels and videos, will be agreed upon before work begins.

Who I'm Looking For

I'm looking for someone with:

Excellent graphic design, typography, composition and art direction skills

Experience creating bold, cohesive social media campaigns

Skills in motion graphics, video editing and mixed-media design

A strong eye for photography-led and editorial content

The ability to identify compelling stories and translate them visually

Creative independence, attention to detail and good communication

Experience working with artists, photographers, cultural organisations or creative brands is particularly welcome.

Familiarity with Adobe Creative Suite, After Effects, Premiere Pro, Figma, Canva or similar tools would be useful.

I'm especially interested in designers whose portfolios demonstrate originality, strong visual taste and the ability to create distinctive content beyond conventional social media templates.

Budget & Milestones

This is a fixed-price project. The final budget, scope, timeline and payment milestones will be mutually agreed upon before work begins.

I anticipate four milestones:

Creative direction and content plan: Review the website and assets, select content and propose an overall approach.

Initial designs: Produce three or four sample posts to establish and approve the visual direction.

Full production: Complete the agreed collection of 16–20 posts.

Revisions and final delivery: Refine the collection and provide publication-ready assets and editable files.

I'm open to proposals based on experience, creative quality and the proposed balance of static, carousel and video content.

To Apply

Please send:

Portfolio links showcasing bold, editorial, textured, animated or photography-led social content. I'd particularly like to see complete campaigns rather than only individual graphics.

One specific post idea inspired by irisarttech.co.uk, explained in two or three sentences. Tell me what caught your eye and how you'd translate it into a social media post.

Your proposed fixed price for 16–20 posts, including the mix of formats it covers (for example, the number of static posts, carousels and videos).

Your estimated turnaround time and preferred milestone/payment structure.

Confirmation that you're comfortable creating both static and animated/video content and providing editable source files.

Please note that my new website is launching soon, the selected freelancer will receive the relevant Dropbox assets.

Applications without a specific post idea inspired by IRIS will not be considered.

I'm looking for a creative collaborator who understands that this is more than producing attractive graphics. It's about translating an established artistic identity into a bold, cohesive and engaging social presence that tells stories, showcases the work, attracts the right audiences and invites people into the wider world of IRIS

I need someone who can help develop an idea for an AR and AI business plan.

We need a developer to create a real-time algorithm that matches physical products with their 3D models in augmented reality.

We have developed an app where using the camera of mobile devices you can insert 3D model of a physical product and see them both together in real time, real size 1:1 scale; main function is to automatically detect differences Vs 3D model and Physical product.

We are looking to match differences on
hole positions less then 0.2mm
hole sizes within +/- 0.1 mm
edges or contours +/- 0.1 mm
missing assemblies, missing pins, nuts, missing welding
if possible, shape or form of product, it would be good, color mapping form according to 3D

Our progress is:
We have got app, we got server side working
But we are upfront to a high cost license for tracking algorithm and dependency to use Apple devices to make this work so we are looking to develop our own algorithm that works on android devices with no license or fees so we can install in our app

Products from 1 to 15 meters length
Assemblies and Welded structures
Stamping molds Metal machined products
Metal housing products

Do you have any experience on this?
Have you ever developed something similar and/or can you development this?

You interested in working for this project, any estimated cost or times that could be designed?

The job consists of designing the cinematography of a 90 second advertisement, as well as of shooting the required footage. The advertisement is for an AR (Augmented Reality) application designed to grant access to all the common features of the headset to the user in a dynamic, attractive heads-up display. Filming will be done directly on the AR headset (Samsung Galaxy XR). We will provide the headset.
The footage recorded will show the application's features being used in a variety of contexts and sceneries.

I need a Lens Studio expert to create a 3D red bird character (similar style to Angry Birds, but an original design) where my real eyes and mouth show through, like the YouTube channel @daumen.

I wear glasses, so the eye area must fit around them.

- Original 3D red bird character
- Working Lens Studio lens with my eyes and mouth tracked
- Full setup so I can use it on my computer for recording
- A walkthrough on how to record YouTube videos with it

Hi, I’m looking for an Unreal Engine developer to build a proof of concept of a locally running, interactive 3D character for a museum-style installation. The character represents a historical painter from centuries ago and is built entirely as a 3D model in Unreal Engine.

What it should do:

Have a spoken conversation with visitors, answering questions based on a supplied knowledge base about the painter’s life and work
Run locally on one computer, without structural dependency on the internet
High-quality real-time 3D look (Unreal Engine MetaHuman), natural facial animation and preferably full-body animation
Ideally placed in a 3D scene where the character performs actions, e.g. painting behind an easel

What this is not: no face swapping, no editing of real photos or video footage, and no cloning of a real person’s voice. The character is a 3D creation with a generic synthetic voice, clearly presented to visitors as an interactive museum character.

I’m open to your advice on software and hardware (e.g. MetaHuman, Audio2Face, local LLM, local speech-to-text and text-to-speech).

Budget: EUR 250 fixed for a working proof of concept, paid when agreed acceptance criteria are demonstrably met. Full handover of source code, project files and documentation is required.

Alternative scope proposals are welcome, but only with proof of comparable work you built yourself (demo video, live link or repository).

Could you share:

2-3 examples of similar real-time 3D character or MetaHuman projects you built
What you can deliver for EUR 250 and what would run locally
Your approach and estimated timeline

Skills: 3D Rendering, Animation, 3D Modelling, 3D Animation, Augmented Reality, Unreal Engine, 3D Visualization, Natural Language Processing, AI Chatbot, 3D Game Art

I’m ready to start streaming on TikTok Live and want an AI-powered face filter running smoothly in real time. I’ll be switching between a MacBook Air and an iPhone, so the workflow has to cover both devices without many hiccups.

Here’s what I need from you: first, recommend the best AI face-tracking or face-swap tools that will actually work with TikTok Live on macOS (Ventura) and iOS (latest). Once we pick the right app—whether that ends up being something like Snap Camera, OBS plugins, or a mobile-first solution—you’ll walk me through installing, configuring, and linking it to TikTok. Screen-share or step-by-step video guidance is ideal so I can repeat the process on my own later.

By the end, I want:
• A shortlist of filter apps with pros, cons, and any license fees
• A tested setup on my MacBook Air (via OBS Studio, Streamlabs, or another route)
• The same effect running directly from my iPhone or through a companion Mac workflow
• A quick reference guide or notes so I’m confident going live any time

When you respond, please include examples or short clips of past work where you’ve helped creators or brands stream with real-time face filters or AR effects. That evidence of prior success will help me choose quickly so we can dive straight into the build-out.

Skills: Mobile App Development, iPhone, Mac OS, Objective C, Video Production, Video Editing, Augmented Reality, Video Streaming, AI Chatbot Development, AI Integration

I need an end-to-end, browser-based MVP that lets kindergarteners learn Mandarin through printed word cards that “come alive.” The web app should use the device camera to recognise each card—individually or in sentence pairs—and immediately launch an animation on top of it via WebAR. Children then speak the word or sentence; the system listens, judges it in Mandarin and, when a syllable is off, gives an instant correction suggestion verbally the child can imitate before moving on.

Four themed learning scenes must be interconnected so a class can start anywhere and cycle until all four are finished. When a new card is recognised inside a scene, its matching video should autoplay without extra taps. Every interaction, score and completion tick feeds a simple teacher dashboard that shows overall group progress at a glance.

I am supplying all cards, images, sentences and videos—you focus on coding, testing and packaging. I’m open to any suitable technology as long as the finished product:

• runs smoothly in Safari/Chrome on iPads and common mobile browsers
• requires no downloads or app-store installs
• ships with clear deployment instructions and full source code

Deliverables accepted when:
1. A classroom-testable build is deployed to a public URL within 7–14 days.
2. Camera recognition, WebAR animations, speech feedback, scene looping, video playback, progress tracking and the dashboard work together reliably for at least 10 students in one session.
3. Source code, build scripts and a one-page setup guide are provided.

If you have relevant WebAR, computer-vision or speech-AI experience and can meet this timeline, I’m ready to start immediately.

Skills: JavaScript, Mobile App Development, CSS, Animation, HTML, Game Development, Augmented Reality, Web Development, Computer Vision, Speech Recognition

PROJECT BACKGROUND AND PURPOSE

We are developing an immersive visitor experience for PIAF, a centre dedicated to the arts of fire at the historic La Taillerie building in Baccarat, in France’s Grand Est region.

The future experience will introduce visitors to the region’s landscapes, natural resources and craftsmanship: glassmaking, crystal, ceramics and artistic metalwork. Visitors will travel above forests and towns, then enter workshops to discover artisans’ gestures and the transmission of their skills. The journey will lead to La Taillerie and its new life with PIAF.

Our aim is to create a memorable opening to the exhibition: an experience that inspires curiosity and makes visitors feel they are travelling through these places. The full production could last approximately ten minutes and is intended for a visitor installation with sixteen standalone VR headsets.

PURPOSE OF THIS FREE TEST

Before selecting a production partner, we need to assess applicants’ ability to create convincing animated VR with genuine stereoscopic depth.

We are therefore requesting a free, unpaid 15-second demonstration: a gentle flight above the Vosges forest, followed by an approach towards Baccarat and a smooth descent towards La Taillerie. We will provide reference photographs identifying the target building.

The test should demonstrate:
- A convincing sense of depth, scale and movement.
- The ability to look around the surrounding environment.
- A smooth camera journey suitable for seated visitors.
- A recognisable approach to the location shown in our references.
- A lightweight deliverable that runs on a standalone PICO or Meta Quest headset. Please specify the supported model and provide simple viewing instructions.

This is a capability assessment only, not a request for the complete experience. The test is unpaid and will be used solely for internal evaluation. Applicants retain ownership of their work; any public or commercial use would require a separate agreement.

A convincing demonstration may lead to a separately agreed paid production assignment, subject to project funding and selection. No future contract is guaranteed. Please apply only if you accept these unpaid test conditions.

Skills: 3D Rendering, Animation, 3D Animation, Game Development, Augmented Reality, 3D Visualization, Unity, Virtual Reality

I’m looking for a creative screenwriter to help develop and write a two-minute standalone short film promoting our library’s tinyFILM Festival, a festival built around one simple challenge: tell a complete story in two minutes or less.
Because of that, the two-minute runtime is not just a restriction—it is part of the point. I want the promotional film itself to demonstrate just how much story, character, humor, and visual imagination can fit into two minutes.
The concept I’ve developed is called The Medieval Arcade: a large, multi-level medieval tavern where fantasy characters play strange medieval versions of arcade games. Imagine the energy of an old-school arcade dropped into a Renaissance Faire/fantasy world—fast, colorful, slightly absurd, and very visual.
Our main characters are the flamboyant Prince of Hearts and his sidekick, Jack of Spades. The basic starting point is simple: the Prince enters the arcade carrying a ridiculous amount of gold, spots a mysterious Grand Prize, and decides he wants it. Naturally, obtaining it turns out to be considerably more complicated than simply buying it.
As he makes his way through the arcade, he encounters its strange inhabitants and attractions: an augmented-reality Wizard, an ethereal patron who cannot successfully drink his mead, a horned bartender, a fantasy hunting game, arcade players whose fighting game is enacted by actual sword fighters, and other bits of controlled chaos.
There is also an idea I would love to explore where patrons throughout the arcade carry medieval-style tablets/slates or enchanted notebooks that function as cameras, and they are creating their own little “tiny films” around the arcade. This could ultimately play into the Prince discovering that his own adventure has become a tiny film.

**However**—and this is important—I want the writer to be creative. These characters, situations, and ideas are the baseline. I am completely open to rearranging them, dropping something that doesn't work, combining ideas, inventing something new, finding a better ending, or taking the premise somewhere I haven't considered. I don't want someone simply converting my notes into screenplay format; I'm looking for someone who sees the concept and thinks, “I know what we can do with this.”
The main requirements are:
- The finished story must work within two minutes or less.
- It needs a genuine beginning, middle, and end, rather than simply being a montage or commercial.
- The Prince/Jack and pursuit of the Grand Prize are my preferred central through-line, but I'm open to creative development of that idea.
- Supporting characters do not all need introductions, dialogue, or individual story arcs. Some may simply be great visual moments as we move through the arcade.
- The tone should be funny, fast, cinematic, fantastical, and visually driven.
- Festival dates/rules do not need to be awkwardly crammed into dialogue. Those can live on our website or potentially appear as signs, props, screens, and visual Easter eggs.
- Any recognizable arcade-game influences should become original fantasy equivalents rather than direct copies of copyrighted games or characters.
- Most importantly, I want the audience to finish the short feeling like they have actually watched a tiny movie—not a two-minute advertisement.
The ideal final reaction is:
“They really told that whole story in two minutes. Maybe I could make one too.”
The initial deliverable would be a beat sheet/story treatment followed by a polished approximately 2-page screenplay, with room for collaboration and revision.
If this strange little world sparks an idea for you, I'd love to hear your take on the premise and what you would do with it, rather than receiving only a generic bid or résumé.

Generative visuals for an IDM/electronic music album (TouchDesigner or similar)

I'm starting the visual identity for my second album and I'm looking for a generative artist to help create the art design/video.

ABOUT THE PROJECT
The first album's visuals were built in TouchDesigner: https://www.instagram.com/p/DWrK-cfjLKJ/
For the second album I want a new design system.

As a reference for direction, I like this particle piece: https://boosty.to/incrprl/posts/3c032526-9851-40ed-87a8-c68e2c57164b

It's a reference for the feel only. I'm just as open to an original concept if you have one, and I'd like to hear your ideas.

WHAT I NEED
- 6 finished stills at 3000 x 3000 px or larger
- 8 short seamless loops, 8 seconds each, delivered in both square (1:1) and vertical (9:16), for streaming canvases and social
- All from one coherent visual system, so the album and singles clearly belong together

WHAT I DON'T NEED
- The project file or a reusable tool. I only need the finished renders.
- Audio reactivity. It's a nice-to-have!

Tooling is up to you: TouchDesigner, Houdini, Blender or anything else that gets the result.

HOW I'D LIKE TO WORK
- Fixed price, split into two milestones: concept and test frames (40%), then final renders (60%)
- Two rounds of revisions
- Full commercial usage rights to the delivered images and loops. You're welcome to show the work in your portfolio after release.

Budget: flexible..Please quote a fixed price for the scope above
Timeline: concept and test frames within 2 weeks of starting, final renders within 4 weeks

This would be a simple Quest 2/3/3S gait-capture app that uses the headset and two controllers attached to the feet to record their 3D movement and orientation during walking. While walking, the user sees a simple real-time visualization of the tracked body/feet, along with tracking status and basic live measurements (negotiable for first version). The app records timestamped raw data for later analysis of gait parameters such as step timing, stride length, walking speed, symmetry, and foot trajectories, with the eventual goal of comparing the results against Vicon.

The simple visualizations:
When you're wearing the headset, you would see a simple 3D representation of yourself, not a fancy avatar:
- Head position
- Pelvis/reference position
- Left foot marker
- Right foot marker
- A simple line/body representation connecting them
- The actual tracked foot trajectories as you walk

So in your terms:
• Head position and rotation tracking
• Left foot/controller position and rotation tracking
• Right foot/controller position and rotation tracking
• Simple pelvis/reference position
• Simple real-time 3D body representation
• Head marker
• Left and right foot markers
• Simple lines connecting the tracked body points
• Real-time visualization of the foot movement/trajectories while walking
• Recording of timestamped raw tracking data, including position and rotation
• Export of the recorded data for later gait analysis

We are developing a 150mm diameter molded-cork fascia/recovery ball with aggressive raised nodes designed to create concentrated pressure for fascia and deep-tissue work.
We already have concept renderings and have been working directly with the cork manufacturer. The manufacturer believes the product is feasible and has provided specific DFM requirements. We now need an experienced industrial/mechanical CAD designer to turn our concept into a single, manufacturing-ready 3D model.
Proposed manufacturing method: The product will be manufactured as two molded cork hemispheres, approximately 75mm high each, which are bonded together around the equator.
The manufacturer has asked us to design the CAD around these requirements:
- Eliminate undercuts that could lock the part into the mold.
- Maintain a clear mold-opening/release direction.
- Avoid deep recesses with vertical or inward-facing walls.
- Add appropriate draft/release geometry.
- Soften or round edges where necessary for successful molding.
- Avoid very thin or fragile features.
- Account for the equatorial joint between the two molded halves.
- Avoid placing critical surface features directly on the joint where possible.
- Maintain consistent geometry and alignment between both hemispheres.
- Account for normal molded-cork manufacturing tolerances.
- Design the equatorial joint so its visual impact can be minimized after bonding and finishing.
Design intent is important: this should NOT become a generic smooth massage ball. The aggressive raised nodes are a fundamental part of the product. We want to preserve as much of the pronounced geometry and concentrated-pressure characteristics as manufacturing allows.
We will provide reference renderings showing the intended design. The CAD designer will need to translate these references into one coherent, symmetrical, manufacturable product, rather than simply copying AI-generated geometry.
The workflow will be:
Initial CAD → review by our cork manufacturer → DFM feedback → CAD revisions → final manufacturer-approved geometry.
We are not asking for production mold/tooling design at this stage. We need the product geometry engineered correctly so our manufacturer can approve it before tooling.
Deliverables
- STEP/STP file
- Native editable CAD file (SolidWorks, Fusion 360, Creo, or equivalent)
- STL for prototype/3D-print evaluation
- Dimensioned drawing/PDF
- Top, bottom and side views
- Section/exploded view showing the two molded hemispheres and equatorial joint
- Basic rendered views for design confirmation
- At least 1–2 reasonable revision rounds following manufacturer feedback
Experience with DFM, injection/compression molding, molded rubber/elastomers/cork, mold-release geometry, draft analysis, and consumer product development is strongly preferred.
When applying, please briefly explain how you would approach the raised nodes on a spherical surface while preventing undercuts and maintaining proper mold-release geometry.
Please include examples of manufacturing-ready molded products or similarly complex organic/spherical products you have designed.
This is a production CAD/DFM project, not simply a 3D visualization/rendering project.

We are looking for a skilled 3D artist to create and optimize a high-quality 3D AI model for real-time use. The model should have clean topology, optimized geometry, proper UVs, and high-quality textures/materials. Experience with Blender and AI-assisted 3D modeling workflows is preferred. The final asset should be lightweight, visually accurate, and suitable for games, AR/VR, or other real-time applications. Please share your portfolio and examples of similar optimized 3D models.

I'm evaluating an immersive e-commerce platform and looking for an experienced development team to provide preliminary feasibility, timeline, and ballpark MVP pricing.

Proposed MVP scope:

• Three.js/WebGL immersive 3D environment
• CMS-controlled 3D/seasonal content
• AR virtual try-on using webcam/photo upload
• Approximately 40 product colors and 15 style variations
• Computer-vision head measurement and head-shape analysis
• Color matching and personalized product recommendations
• Shopify commerce integration with inventory/order synchronization
• TikTok Shop and Amazon integrations
• Customer accounts with saved try-ons/recommendations
• Creator/affiliate dashboard with attribution, commission tracking and payouts

• Secure cloud deployment with PCI-DSS, GDPR/CCPA and SOC 2 readiness considerations
Anticipated stack includes Next.js/React, Node.js, PostgreSQL, Redis, Three.js/WebGL and AWS/Vercel, although I'm open to technical recommendations.

At this stage, I'm looking for:
Whether this is within your team's capabilities
What components your team can handle directly
Ballpark MVP development cost
Realistic development timeline
Whether AR/computer vision should be custom-built or leverage existing technology

This project is currently in the evaluation stage. I'm gathering preliminary feasibility and pricing before moving forward. I'm not requesting unpaid development, prototypes, or detailed architecture at this stage.
