An ear piece could read out a question. A smart watch could detect a binary response.

2. Could the smartwatch detect more than a binary response? The entropy of the message = number of accurate + accessible gyroscope states.

I ask these questions because last week I formed an idea about using wrist rotation as a steerable interface on an index of human knowledge.

The transaction costs of interacting with devices are both mechanical and social.

Hopefully the apparent nervous twitch localised to your wrist would not be a give away...!

(jokes obv.) That could be made subtle. I think it is probably possible to create a prototype of this right now.

You could ignore the preliminary problems I foresee with choosing the domain of knowledge quickly and just move ahead with interfacing.

I guess what is exciting about this idea is that it wasn't possible at all before the creation of smart watches that could detect movement.
