    Depends on what the vector of the force is, and so on, I believe. Do you want to measure downward pressure, pressure on the mouses buttons, lateral motion?

    Do you want to measure the force on/in the arm, or that applied to the mouse and then extrapolate that to approximate what is happening to the person?

    Design considerations and elaboration ;o)

    Do you want to measure force in all three axes?

    Why not start with a kitchen, post office or bathroom scale?

    When at work or working with "mentally ill" children, do you refer to them as spastics? lol

    I thought you'd need an accelerometer to do this type of job?

    CJ, spastic used to be a well recognised and acceptable term used to describe those with cerebral palsy.

    But the word has been used (misused) as an insult of recent, and thus you have highlighted the stigma synonymous with it.
