Current, state of the art firefighters equip collect this sort of info and 
transmit it to a monitoring station for the safety of the firefighter.

Subject: [EE] Biometric & Motion measurements

> heart rate, rate of breathing(?), skin conductance) along with an
> accelerometer on the back hand or the back of the cue stick and a
> pager-like device with two buttons that would let the player indicate
> shots that were made or missed.

> straight - sometimes, it's not known WHY shots aren't going in, so if
> there is unintentional side-to-side motion in the stick while a shot
> is being made, that would be a very interesting data point).

> - what other parameters may be interesting in this context
> - processing - centralized or distributed
> - connectivity (probably wireless, to make it less obtrusive to the 
> player)
> - any pointers to reading materials about any of the relevant topics

> Thanks for any ideas also.
