This study investigated elderly users’ understanding of images and their perception of products. Various product function images served as testing samples, and participants were required to rank the various images. The results of this study revealed that the elderly participants easily recognized concrete images or images that were familiar. The elderly participants had various views concerning simplified images. Associative images that could not be associated with objects from daily life were not efficiently recognized. In the present study, we only explored the effect of shape and elements used on elderly people’s understanding of images. The results of this study can serve as a reference for designers when constructing a product’s user interface to be used by elderly people.
