Smart rings are used for contactless payment, smart lock operation, and health monitoring. For applications such as electronic payment and unlocking smart locks, the implementation of a user authentication system in smart rings is essential; however, some challenges remain. Fingerprint authentication is sensitive to f…
We introduce FlexEar-Tips, a dynamic ear tip system designed for the next-generation hearables. The ear tips are controlled by an air pump and solenoid valves, enabling size adjustments for comfort and functionality. FlexEar-Tips includes an air pressure sensor to monitor ear tip size, allowing it to adapt to environm…
We introduce EarHover, an innovative system that enables mid-air gesture input for hearables. Mid-air gesture input, which eliminates the need to touch the device and thus helps to keep hands and the device clean, has been known to have high demand based on previous surveys. However, existing mid-air gesture input met…
Hearables are highly functional earphone-type wearables; however, existing input methods using stand-alone hearables are limited in the number of commands, and there is a need to extend device operation through hand gestures. In previous research on hearables for hand input, user understanding and gesture recognition…
We propose a novel biometric authentication method that leverages sound leakage signals from hearables that are captured by an external microphone. A sweep signal is played from hearables, and sound leakage is recorded using an external microphone. This sound leakage signal represents the acoustic characteristics of t…
