I am a PhD student in Computer Science looking into sensing the human activity in order to make computing applications more 'aware' of users, their state and environment.

In particular I would like to infer the coarse activity of the human being (e.g. walking, running, standing) using wearable insole FSRs.

I've read about Force Sensing Resistors on this mailing list and on the Internet, but still have some questions.
Not having any biomechanics background I'd like to find out:

a) does it make sense to pursue this direction of using an insole force sensing resistor to infer just the coarse activity of the human (I am not interested in the gait analysis etc.).
b) does anyone have any experience with building such a sensor (i.e. if I use the FSRs from Interlink what would be the best interface?) - any tips & pointers would be appreciated
c) are there any existing databases with FSRs and where could I find them ?

Many thanks,
