AI Gesture Control for 3D Workflows

Translate hand gestures/signs into precise CAD/DCC commands in real time.

🔓 Project is open source

What is MotionCoder?

MotionCoder is an AI-powered, modular, on-prem framework that maps 3D hand gestures/signs to intents + parameters, live values (e.g., draw circle, split edge, move 5 mm) and executes them in target apps. Beginner-friendly core gestures; no sign-language knowledge required.

Benefits

More efficient: do more with fewer steps.
More ergonomic: less micro-movement, more focus.
More speed: real-time gestures → commands.
Less time: fewer mode switches and dial ogs.
Fewer clicks: gesture-first interactions.

Real-time, low-latency pipeline • Undo-safe integrations • Reproducible runs

Video demos

No videos yet — the project is still in an early prototyping phase. A first demo is in progress and will be published here once ready, with regular updates on YouTube. In the meantime, you can read the pitch below.

My Company Name and Logo

Originally, I wanted a very short domain name (for example, xxxx.ai). Since most four-letter .ai domains are already taken, I decided on xtan.ai – it happened to still be available, so I registered it.

The logo is based on a straight line and a tangent curve: together, they form an X with an integrated S-shaped arc. You can visualize this by plotting y = 1.5x and y = tan(-0.5x) { -π < x < π }.

About & Contact

In short: I’m moving into the software development field.
