Abstract

ABSTRACT: The high mobility of smart watches can easily impair interaction performance, and many applications are squeezed into an extremely tiny screen, which causes disorientations. Therefore, this study examines the extent of performance impairment caused by user movements and proposes navigation aids to alleviate the impairment. An experiment was conducted among 28 college students to investigate the influence of user movements and navigation aids on users' performance and subjective feedback. The results indicate that the performance of using smart watches in walking conditions is comparable to that in sitting conditions. However, the use of smart watches while running reduces the success rates of operating, perceived ease of use, perceived usefulness, and flow experience, and it increases subjective cognitive workload. To improve user experience, the effectiveness of providing navigation aids for smart watches is confirmed. Using static navigation aids while sitting and walking and using animated navigation aids while moving can significantly improve users' perceived ease of use and perceived usefulness and decrease cognitive workload. Based on these results, guidelines for tailoring the interface design of smart watches to user movements through navigation aids are proposed.
