DuoEar: イヤホンの片側を別用途に使用する手法の提案

In this paper, we propose a method that utilizes each side of the earphones for different purposes, deviating from the typical use of earphones as a hearable device that outputs sound. The earphones “RN002 TW” used in this paper are equipped with various sensors, including a 9-axis sensor, enabling them to capture the movement and status of devices and fixed objects. As an experiential scenario where each device can be used for different purposes, attaching one side to the ear and the other to the hand allows for various interactions. For instance, it is possible to play different sounds while performing headbanging by capturing data from the head posture and the hand’s surroundings. Another proposed experience involves wearing the device on the user’s ear, with the other end embedded in a ball. This setup provides the user with auditory feedback of the swish of ball, as well as its speed and rotation.
