Product Interfaces for Older Adult Users With Cognitive Impairment

The aim of this study is to explore the usability of multiple forms of television remote control interfaces for older adult users and users with mild cognitive impairment (MCI) to clarify the operation performance requirements of these two user groups. The test interfaces were constructed through programming and were capable of recording participants’ task completion time, operation errors, and the locations of their taps. The results show that users with MCI could not perform their initial action quickly and accurately; buttons with larger sizes provided greater operation performance for older adult users and users with MCI.
