KnuckleBoard is an experimental keyboard interface developed by researchers at KTH Royal Institute of Technology and Ericsson Research for easier typing in mixed reality.
The interface takes advantage of proprioception, the body's sense of movement and position, by allowing users to type by tapping on their own knuckles with special gloves.
The KnuckleBoard prototype consists of two gloves with conductive pads on fingertips and knuckles, monitored by Arduino boards, enabling users to type alphanumeric characters in a VR or AR environment.
Users testing KnuckleBoard found it effective for typing while sitting, standing, and walking, hinting at potential applications beyond typing such as in VR, AR software, and games.
