> A motion-controlled pointer that reads hand movement in free space — IMU sensing, sensor fusion, and low-latency firmware mapped onto standard input.
// signal path
Reads an onboard accelerometer/gyroscope and fuses the axes into a stable orientation estimate, turning hand motion in free space into cursor movement.
Filters and combines noisy IMU readings to suppress drift and jitter, so small intentional gestures map cleanly to smooth on-screen motion.
Bridges the device to the host as a pointer, translating processed motion into standard input events the operating system understands.
Tight C++ firmware samples the sensor at a fixed rate and streams cursor deltas with low latency — responsiveness is the whole point.
