Age Differences in Performance, Operation Methods, and Workload While Interacting with an MP3 Player
This study aimed to reveal age-related interaction characteristics through user observations. The interaction behaviors of comparatively younger adults (20s) and older adults (40s~50s) were examined while they used an MP3 player, and age-related differences regarding performance, operation methods, and workload aspect were analyzed. The results reveal that the higher error frequency, poorer ability in terms of physical operation, and the lower subjective performance of the older adults are due to an age effect while higher workload aspects are due to a lack of background knowledge.
