An egg-shaped dual camera that sees body and club movement


Sports Egg helps you understand your golf swing and know what to adjust next.
Sports Egg combines an egg-shaped dual-camera device, motion AI, and a progressive curriculum. It reads your swing, explains what’s off, and gives you one change to test next.


Technology
Real-time 3D pose estimation from RGB cameras, adapting across body types and movement styles.
Graph neural networks plus anatomy-aware constraints interpret the biomechanics behind a movement and pinpoint the meaningful error.
A sports knowledge base and persistent memory generate outcome-oriented voice coaching—focused on whether the movement improves the result.

Research background
Sports Egg brings together visual perception, temporal modeling, and biomechanics to understand movement and turn research into practical coaching feedback.






Calibration-free 3D reconstruction helps the system read your movement without making setup the first part of practice.
0.81 px reprojection errorLightweight inference helps movement analysis happen within the flow of practice, so feedback can return before the next attempt.
147 ms inferenceCross-user generalization is designed to reduce the need for complex individual setup when a new athlete starts training.
<1.5% accuracy drop for new usersBiomechanics-informed analysis looks at relationships between movements, creating a foundation for feedback that explains more than what moved.

How it works
Dual cameras read your full swing at 60 FPS — no wearables, no calibration.
Anatomy-aware AI pinpoints the true root cause of the error, not just what moved.
One clear, spoken adjustment — delivered before your next shot, every time.
Every swing re-enters the loop. Your training record builds with every session.
From signal to coaching cue in under three seconds — every swing.
Future platform
Every sport deserves a serious approach. We learn from real coaches and training data to understand each movement in depth—not just offer generic guidance.
