2D-RFID input at the tip of your fingers

Researchers at the University of Waterloo in Canada have developed a novel hand-based input technique called Tip-Tap that amazingly requires no batteries.

The wearable device uses a series of three custom RFID tags on both the thumb and index finger with half an antenna on each digit. When the fingertips are touched together, a signal is sent to the computer indicating where the thumb and index finger intersect, which is mapped as a position on a 2D grid.

Usability experiments were carried out using an Arduino Mega, with both on-screen visual feedback and without. Possible applications could include the medical field, where Tip-Tap can be added to disposable gloves enabling surgeons to access a laptop without dictating inputs to an assistant or sterilization issues.
