Objective To analyze the distribution of hand sizes of university students and study the effects of users' hand sizes on the operation on touch screen mobile phone. Method In this study we collected hands' data from 250 university students and classified their hand sizes into three types(small, median and large) by cluster analysis firstly, then we adopted serial target pressing task to explore the effects of different hand sizes on the operation performance of touch screen mobile phone. Results(1) University students' hand-type sizes accord with normal distribution in general;(2) When the median size mobile phone is used, the performance of the three hand-types of users have no significant difference, large-hand users' hand muscles are more labor-saving than others, and median-hand users hold better subjective evaluation than small-hand users and large-hand users. Conclusion University students' hand-type sizes accord with normal distribution. Hand-type sizes significantly affect the use of touch-screen mobile phone, large-hand and median-hand users' use it better than small-hand users.
