GalvaPhone is the expansion of EMotoPhone, an earlier project in the Speech Interfaces group. EMotoPhone allows cell-phone users to choose a face manually, representing their current emotion, and send it over a cell phone to another user. The recipient of the EMotoPhone face can then decide whether to accept a phone call from the sender. With GalvaPhone, information about a user's electrodermal activity (also known as the galvanic skin response) is also sent, in addition to the user's self-selected emotion. The electrodermal activity measure is determined by a galvactivator-a glove that measures skin conductivity.
