An Efficient Disposition for Wrist-Worn Device Usage Time Expansion in Wearable Computing Environment

Abstract

Wrist-worn devices have merits of usability such as glanceability, faster reaction time, and low access time. However, usability is restricted by difficulty from mid-air interaction which can cause fatigue and muscle damage. Traditional disposition for wrist-worn users considers only interaction between devices and users who wear devices outside of the wrist. In this paper, we propose efficient disposition (ED) which can expand the usage time for long time use. ED has two disposition for glanceability and long-time use. The former turns the power on all the time for time, blood pressure, heart rate, and blood sugar confirming with low energy consumption. The latter uses for text entry, viewing pictures and videos and so on. Consequently, ED can hold and sustain wrist-worn devices for a long time, therefore it enables users to enjoy better usability.
