Designing More Private and Socially Acceptable Hand-to-Face Gestures for Heads-Up Computing

We propose a subtle one-handed finger interaction technology for heads-up computing, which utilizes the proprioceptive advantages of the face as the contact surface combined with the imperceptible characteristics of micro-gestures to improve the social acceptability and privacy of hand-to-face gestures in public environments. Its implementation was based on the use of a finger IMU which can collect data generated by finger movement. We verified the feasibility of this interactive technique in three public environments and the results of user study showed that our Interactive technology performed good social acceptability and privacy.
