Design and Implementation of an Input Interface for Wearable Devices using Pulse Wave Control by Compressing the Upper Arm
Yuma Akimoto, Kazuya Murao · 2021
In this paper we propose an input interface for wearable devices that enables simple command input by sensing blood flow changes using a pulse sensor installed in many wrist-worn wearable devices caused by body compression. The proposed method consists of four processes: pulse measurement, peak detection, calculation of the time interval between peaks, and command transmission. We proposed four input methods to determine a command based on the combination of compression patterns, and conducted an experiment in which four subjects were asked to choose one of several options with each input method.
