OpenSeizureDetector - Pebble Version

This seizure detector uses a (Pebble)[http://getpebble.com] smart watch. The watch has an accelerometer and vibrator motor and a bluetooth radio to talk to another computer. Most importantly, it comes with instructions to write code for it on the manufacturers (web site)[http://developer.getpebble.com].

So it is an ideal platform for an accelerometer based seizure detector similar to the Arduino based one I made in 2013. For more details see the (OpenSeizuredetector)[http://openseizuredetector.org.uk] web site.

Principle of Operation

It is based on an accelerometer monitoring movement. It uses a fourier transform to extract the frequency spectrum of the movement, and monitors movements in a given frequency band. The idea is that it will detect the rhythmic movements associated with a seizure, but not normal day to day activities.

If the acceleration within the given frequency band is more than a threshod value, it starts a timer. If the acceleration remains above the threshold for a given period, it issues a warning beep. If it remains above the threshold for a longer specified period, the unit alarms (continuous tone rather than beep).
