GSR This app is brilliant! It allows kids (and adults!) to make their own GSR electrodes for a lie detector test or stress indicator and it really works! Great for science fair projects or just for fun. Make sure you follow the directions carefully when making the electrodes.
Can someone kindly tell me the threshold levels used to determine the GSR levels? As in, the screen is made to change colours from blue (neutral) to red (stressed). At what GSR level is the distinction made?
Amazing idea I totally never hit this though: the ear phone could be used to a sense of heartbeat.
Made time between samples 0.2 seconds.
Some improvements for Samsung phones
