RESEARCH

Development of Technology to Utilize Sound Leakage Signals

We are developing interaction and personal authentication systems for hearables.

We focus on the sound leakage of hearables and obtain information on the auricle and hand shape from the echoes of the signal leaking outward.

We use machine learning to recognize hand shapes or identify individuals.

We are exploring the possibility of sound leakage signals.

Clothing Gesture Input for Common Clothing

We have developed a method to use common clothing as a touch interface using acoustic sensing.

This wearable device is removable and designed to transform a common clothing item into a smart clothing.

By using familiar clothing as a touch interface, a more comfortable and natural input method is achieved. More…

Facial Expression Recognition for Hearables

We have developed a system that recognizes the user’s facial expressions by utilizing the reverberation characteristics of the ear canal.

The system is expected to be applied to gesture input and facial expression recognition.

Since this system can be implemented with only a speaker and a microphone, it has the advantage of low cost of implementation on hearables. More…
