ScanRing: Hybrid Authentication System in a Ring Device Using a Distance Sensor and an IMU Sensor

Takashi Amesaka

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… MoreScanRing: Hybrid Authentication System in a Ring Device Using a Distance Sensor and an IMU Sensor

Exploring User-Defined Gestures as Input for Hearables and Recognizing Ear-Level Gestures with IMUs

Takashi Amesaka

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,… MoreExploring User-Defined Gestures as Input for Hearables and Recognizing Ear-Level Gestures with IMUs

EarHover: Mid-Air Gesture Recognition for Hearables Using Sound Leakage Signals

Takashi Amesaka

We propose a novel gesture recognition method, “EarHover,” which enables mid-air gesture input for hearables. This method focuses on the phenomenon of sound leakage specific to hearables and utilizes speakers and external microphones, which are highly compatible with hearables, for… MoreEarHover: Mid-Air Gesture Recognition for Hearables Using Sound Leakage Signals

EarLock: Personal Authentication System for Hearables Using Sound Leakage Signals

Takashi Amesaka

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
