Ever since I got the Parallax / Grand Idea Studio Emic2 sound board I've been wanting to find some way to mimic the hands-free typing / speech system used by Stephen Hawking. And when I figured out how to get the Neurosky Mindwave Mobile headset to identify blinks, I realised I could use blinking as the single minimal-effort input into the system to control a keyboard menuing system.
The system sweeps through rows until I blink, then sweeps along the row to select a character or action with another blink. If I let it go past the end, it cancels and carries on sweeping rows.
See my other projects for more on how to setup the BlueSMiRF for auto-connecting to the NeuroSky headset.
