Quiet Blink

Imagine reading a page and accidentally sending a command because you blinked twice. MindClick is my prototype for deliberate blink commands. Quiet Blink tests its rules in Python on public forehead EEG, electrical recordings made through scalp electrodes. A false activation means the rules send a command when none was requested. Separate copies with simulated commands added let me count missed commands too.

Both extra checks reduced unwanted outputs from 54.3 to 42.0 per recording-channel hour, about 23% fewer, while the injected-command miss rate stayed near 26%. That is useful progress, but still too error-prone for reliable control. Device validation remains future work.
