University of Waterloo computer scientists have developed a computer input device that works by simply touching the fingertips in different ways. Called Tip-Tap, it doesn’t require batteries or other modes of power, but instead uses radio frequency identification (RFID) tags to sense when fingertips touch, thus making them perfect for disposable surgical gloves. This means they would have access to things like x-rays and diagrams, without having to touch anything.
So far, they’ve developed a prototype, in collaboration with the National Research Council of Canada (NRC), that consists of a halved RFID antenna with each side boasting three chips to allow two-dimensional fingertip input. Tip-Tap can be built into a glove or directly attached to the skin like a temporary tattoo.
