    do finger touch produce some specific change in cap. As it don'tg work for pen/pencil either unlike in mobile touch pads.

    It may be a capacitive touch pad, those do not work unless you get a capacitive stylus or use your finger, some are resistive which work with anything that can apply pressure.
