// THE GAME
Asteroids fly toward your face. Tilt your hand up — they retreat. Tilt down — they rush forward. No buttons. No controllers. Just discrete thumb-to-finger gestures tracked by VR cameras.
// CONTROLS
// INTERACTIVE DEMO
A real game loop. Move your mouse left and right — the ship follows. Asteroids rain down from the void. In the lab, this same mechanic is driven by your fingers: a discrete thumb-to-pinky gesture commands lateral motion. Same brain circuits, prettier graphics.

Mouse becomes hand
In this demo, mouse X drives ship X. In the VR build, the same input arrives from your fingers — a discrete, individuated motor command.
Every dodge logs
Time-to-evade, error margin, sustained accuracy — these aren't game stats, they're motor-learning measurements. The lab reads them at 48 Hz.
Action → feedback → adapt
A motor skill emerges from the loop you're closing right now. Multiplied across thousands of players, that loop becomes a population-scale motor learning curve.
// MODULAR PLATFORM
Hand Solo is built as a versatile platform. The same core game adapts to multiple input modes, from clinical-grade VR to a phone in your pocket. Every interaction — patient or not — feeds back into a single research dataset.
VR + Visual Hand Tracking
Standalone VR headset. The integrated cameras track your fingers in real time. Discrete thumb-to-finger gestures control the ship — pinch to steer, oppose to fire, lateral shift to evade.
VR + sEMG · AI
Same VR experience, deeper signal. A surface electromyography wristband reads muscle activation directly. An AI model decodes intention from the raw EMG — useful when fingers don't yet move on their own.
Accelerometer · Whole Body
Phone or wrist-band accelerometer. The whole body becomes the controller — lean, step, shift weight to steer the ship. Designed for balance training in older adults and post-stroke patients.
Mobile · Console · PC
For everyone else. A real, fun arcade game on your phone, console, or computer. Tilt, drag, swipe, gamepad — whatever you have. Healthy gamers play for fun; their motor data broadens our research dataset.
Every input feeds a single research dataset
Whether the ship was steered by a clinician's patient in VR, a senior with a phone, or a teenager on a Switch — every trial lands in the same data lake. Reaction time, error patterns, learning curves, gesture timing.
// INGEST
All 4 modes stream anonymized motor traces in real time.
// LEARN
The lab fits population models of motor learning across age, condition, and skill.
// FEED BACK
Improved difficulty curves, gesture libraries and protocols ship back to every mode.
