Ready when you are

A helper presses Start (or the S key). Then tilt your head to choose and hold a long blink to speak.

Set up HeadVoice first

Tilt to choose. Hold a long blink to speak. A long blink with nothing chosen shows more messages.

Calibrate HeadVoice

About 25 seconds: tilt in each direction, blink normally, then close your eyes three times. A low tone means close your eyes, a high tone means open them.

Cloud processing uploads the 25-second clip encrypted, uses it once to compute your settings, and deletes it right away.

Low tone: close your eyes. High tone: open them.
