モバイルデバイスのためのベルト巻取り機構を用いた省エネルギーでの振動提示

抄録

For operation and experience in mobile devices, vibration feedback is used in addition to audio-visual feedback. In general, however, the vibrators need to drive the entire body of the device which is larger than the actuators, and it is difficult to present a strong vibration stimulus in a mobile environment requiring small size and low energy actuators. Therefore, we propose a device that drives by winding a thin belt with DC motors, and presents vibration by touching the belt with a fingertip. This method makes it possible to present vibration with low energy by vibrating a lightweight belt instead of the entire device body. In this paper, we measured the frequency characteristics of the proposed device and compared the power required for the vibration presentation with the conventional vibrators. As results of experiments, it was confirmed that the proposed device can present vibration with less energy than conventional devices.
