Many of us have gotten used to using touch enabled devices to get work done and play. Wouldn’t it be nice if your tablet could biometrically identify and authenticate you? Biometric Touch Sensing by Christian Holz @ Microsoft Research aims to address just that. With each time, the touchscreen senses the input coordinates and obtains biometric data to identify the user:
watch prototype Bioamp senses the impedance profile of the user’s wrist and modulates a signal onto the user’s body through skin using a periodic electric signal. This signal affects the capacitive values touchscreens measure upon touch, allowing devices to identify users on each touch.
Such a approach would make it easier for tablet users to interact with their device without having to worry about passwords or any interruptions to their workflow. More information is available here.
