Abstract
A computer-implemented method for measuring skin conductance of a writing instrument's user, including: applying a DC voltage to user's fingers contacting the writing instrument during a writing session with the writing instrument; measuring a current generated by reverse iontophoresis following applying the DC voltage; calculating an average skin conductance over a specific timeframe from the measured current; storing calculated average skin conductance data as historical data; comparing the average skin conductance to historical data from the same user or to reference data from a group of users; and providing an indication to the user in case that the skin conductance has decreased and/or the calculation results.
