The reason for this problem was bad usability. It is an important issue for developing method or techniques to evaluate usability. As Jay et al. (2008) concluded, there were five techniques for evaluating usability and they were using questionnaires, screen captured scene, eye activity data, activity observation and interviewing. And based on our literature review, we customized a psychological usability questionnaire which considered effectiveness, efficiency, satisfaction, error-prevention, learnability, sociability, and mental workload, generating a tool meant to reveal the subjective cognition of product usability. This research develops an approach for measuring the usability of a motion-related health management product by using psychological data gathered from questionnaires and physiological data gathered from a heart rate sensor and an eye tracking device. Our analysis shows that the psychological data and physiological data tends consistent when the cognition appears to be positive on usability. The finding and suggestions enable motion sports designer guidelines to reduce the deviation of exercise effectiveness and efficiency of visual information receiving so that could improve the usability of their products.
