摘要: Studies have shown that walking has a negative effect on input performance mobile devices. Runners often use their GPS-enabled smartphones to record exercise, but the of running touch screen not yet been quantified. This study aims fill this gap by performing Fitts’ law experiment smartphone. Pointing tasks were performed in conditions where participants either or stationary, and device was handheld armband worn arm armband. Compared stationary conditions, showed higher motion time lower accuracy. Overall approximately 47% compared conditions. Furthermore, speed decreased 26% when interacting with device. Therefore, common interactions while should be foreseen developers designers applications. And although easier targets contribute performance, most importantly, GUI forgiving user error typical context user.
