TouchRing: subtle and always-available input using a multi-touch ring

We propose a finger-worn touch device TouchRing to provide subtle and multi-touch input. TouchRing leverages printed electrodes and the capacitive sensing technique to detect touch input. It allows users to perform multi-touch gestures in one hand to increase input modality. TouchRing worn on the index finger allows multi-touch using the thumb and middle finger. Ten multi-touch gestures are designed in this paper. We also propose touch detection and gesture recognition approaches in TouchRing. Gesture Recognition accuracy is evaluated in the user study. Applications for TouchRing are also proposed to make controlling smart glasses more convenient.
