In this study, we show a new gesture recognition method for clothing-based gesture input methods using active and passive acoustic sensing. Our system consists of a piezoelectric speaker and a microphone. The speaker transmits ultrasonic swept sine signals, and the… MoreGesture Recognition Method<br>Using Acoustic Sensing on Usual Garment

Earphone-type wearable devices, also known as “hearables,” will have many functions in the future. Some of those functions will require authentication of the wearer for access to the user’s privacy information or settlement of payments. In this study, we propose… MoreEarLock: Personal Authentication System for Hearables Using Sound Leakage Signals

In this study, we propose a new input method for mobile and wearable computing using facial expressions. Facial muscle movements induce physical deformation in the ear canal. Our system utilizes such characteristics and estimates facial expressions using the ear canal… MoreFacial expression recognition using <br>ear canal transfer function
