In modern electronic business era, the currently popular topic of wearable computing devices (WCD) has prompted foreign and local industry players to look proactively into various WCD-related developments, including the external appearances of WCD hardware, software applications, human-device interface designs, and the appearances of WCDs expected by general users. Setting aside the necessary functional specifications and application requirements of WCDs, the wearing habits that general users have already developed is a more fundamental consideration. These habits should form the basis for the design of both WCD hardware and software at the technological level. In this paper, an analysis is made of the items that general users customarily wear and the purpose(s) and frequency of wearing them. The findings will serve as a reference for industry players who wish to enter the WCD market.
