Abstract

This study evaluated the influences of mobile phone interface design on the operating performance of aged people. To achieve the objective, the present research adopted a 2×2 within subject experimental design to develop different experimental treatments based on two types of software interfaces and two types of hardware interfaces. A total of 20 subjects including 10 younger participants (15-30 years old) and 10 older participants (over 40 years old) were tested in this experiment. Three dependent variables were under study. One measure refers to the operating time of subjects who were requested to perform several tasks in the experiment. The second measure refers to the error frequency, defined by the number of incorrect steps that subjects make when they perform the tasks. The third variable was the subjective convenience that was measured by a seven-point Likert scale. Finally, this study discussed design directions in cell phone design for the aged people. The conclusions from this study provided a useful reference for the mobile phone designer.
