You Can Touch This
We might soon have touch-screens on our arms. TouchÃ©
, a gesture-tracking system developed by the Human Computer Interaction Institute at Carnegie Mellon University and Disney Research applies Swept Frequency Capacitive Sensing technology (see a nifty demo video here
). Whereas traditional touch-sensing receives input from a screen and tracks a limited array of gestures, TouchÃ© can be wired to receive input from contact with any surface, including table-tops, doorknobs, and even human limbs. It distinguishes between different gestures by monitoring the sources and amount of pressure applied to a surface.
TouchÃ© holds great potential for innovation in education technology. Using TouchÃ© to facilitate input in augmented reality and wearable computing projects like Google Glass, students would be able to interact and communicate more effectively within a virtual classroom. TouchÃ© could also lead to innovative ways to learn tasks that involve fine motor control (such as playing the piano in the absence of a piano). How else might TouchÃ© be applied to education?
