Researchers at the David R. Cheriton Cheriton School of Computer Science have created a device for wearable computer input suitable for many situations, just by touching your fingertips together in different ways.
Called Tip-Tap, the device is inexpensive and battery-free because it uses radio frequency identification (RFID) tags to sense when fingertips touch. The device could be added to disposable surgical gloves, allowing surgeons to access preoperative planning diagrams in an operating room.
