The issue of memory over-load turned out to be the critical problem of the usability for the elderly, due to the complex menu structures. Thus this study is meant to explore a suitable menu structure for the senior user, and provide suggestions for the relative researches.The study results are:1. Gender: There is no significant between male and female in the operating performance.2. Menu structure: the performance of the hybrid structure is superior to the linear structure.3. Display mode: There is no significant between the horizontal and vertical display modes in operating performance.4. Task Complexity: A positive ratio between task complexity and menu topological structure was revealed, the harder the task complexity, the better performance of mixed structure can be expected.
