Using High Frequency Accelerometer and Mouse to Compensate for End-to-end Latency in Indirect ...
summary
A hardware+software prototype embeds a high-frequency accelerometer into a mouse (Arduino Leonardo bridge) and predicts pointer position with a second-order Euler integrator combining optical velocity and measured acceleration. Compared to derivative- and smoothing-based predictors it yields lower lateness and jitter; lab studies (10 for model fitting, 12 for performance) show 16 ms compensation improves target-acquisition time with no side effects and 33 ms can give ~16% speedup under high added latency, but large compensation causes an elastic snapback and needs 1000 Hz input.
