Abstract
Techniques are generally described for touch-sensitive devices with biometric information determination capabilities. The touch-sensitive device may include one or more of a transmitter, a receiver, and a processor. The transmitter may be configured to emit light towards a surface of the touch-sensitive device and the receiver may be configured to receive reflected light from a touch to the touch-sensitive device. The processor may be arranged to receive signals from the receiver and determines biometric information, and in some examples location of touch, based on the signals.
