## Abstract

A computing device includes signal generation circuitry and also includes a location on the computing device that is operative to couple a signal generated by the signal generation circuitry into a user. For example, the computing device includes signal generation circuitry that generates a signal that includes information corresponding to a user and/or an application that is operative within the computing device. The signal generation circuitry couples the signal into the user from a location on the computing device based on a bodily portion of the user being in contact with or within sufficient proximity to the location on the computing device that facilitates coupling of the signal into the user. Also, the signal may be coupled via the user to another computing device that includes a touchscreen display that is operative to detect and receive the signal.
