Richard Nieva reports on SilentSpeller, a hands-free interface for inaudible texting. Developed by University of Tokyo PhD student Naoki Kimura, the prototype provides users with a 1164-word dictionary accessed through tongue movements detected by an existing smart retainer product. Working under the guidance of Google Glass technical lead Thad Starner, Kimura will present the project at CHI22 this spring; potential applications include aiding sufferers of Parkinson’s disease and other motion disorders.
