PoseSonic: 3D Upper Body Pose Estimation Through Egocentric Acoustic Sensing on Smartglasses

"In this paper, we introduce PoseSonic, an intelligent acoustic sensing solution for smartglasses that estimates upper body poses. Our system only requires two pairs of microphones and speakers on the hinges of the eyeglasses to emit FMCW-encoded inaudible acoustic signals and receive reflected signals for body pose e…

C-Auth: Exploring the Feasibility of Using Egocentric View of Face Contour for User Authentication on Glasses

In this paper, we present C-Auth, a novel authentication method for smart glasses that explores the feasibility of authenticating users using spatial facial information. Our system uses a down-facing camera in the middle of the glasses to capture facial contour lines from the nose and cheeks. The images captured by th…

HPSpeech: Silent Speech Interface for Commodity Headphones

We present HPSpeech, a silent speech interface for commodity headphones. HPSpeech utilizes the existing speakers of the headphones to emit inaudible acoustic signals. The movements of the temporomandibular joint (TMJ) during speech modify the reflection pattern of these signals, which are captured by a microphone posi…
