Hands-Free Mouse Uses Eyes And Muscles Instead

A hands-free computer mouse built using the Neuro PlayGround Lite board combines head tracking via an IMU sensor with biological signals to replicate standard mouse functions. Head movement pans the cursor, jaw clenching triggers a left click via EMG electrodes, and eye blinks (single triple or double) handle right-click and drag via EOG signals. The project demonstrates how accessible input devices can be built from off-the-shelf components as an alternative to expensive commercial solutions.
