mesureing stress by keyboard.

I was having a chat about thinking of generating poetry to create memorable passwords with Paul. This moved on to thinking about measuring identityby using the way we type ( the pattern of time between keys ) as the measure.

Paul made the observation that we might type diffrently when angry or stressed. So the observation that we might beable to do a simple stress monitor by looking at the way we type. Quite a low tech way to augment a machine to measure users 'state'. down side is the training period.

I suggessted using the accellerometer in the laptop to detect taps against the side ( as I am stress punishment). Or have a soft club you could use to hit things - this would be measured and sent back to the stick.
