Re:Show HN: Skate Moves – Spatial pro skating with real-time... by culturengine on Tuesday August 19, 2025 @12:59PM (#44953685)
Hi HN! I'm Andrew from Spatial Magic (https://spatialmagic.ai).

This project uses computer vision to track body movement and simulate pro skating moves in real-time. You can ollie, manual, 180, 360, and grind. Crouching in a squat position will boost your speed.

Video demo: https://youtu.be/RPbfttCTpDE

Running on a MacBook Pro, we've optimized the latency to ~10ms, so the avatar feels like it mirrors your body movements and represents you, which makes the experience much more expressive and immersive.

This is part of a bigger effort, where we're building spatial computing experiences beyond wearables.

We'd love feedback on what tricks and gameplay you would like to see next!
