The Center for Usability and Aging Research (CUAR) assemble data for over 170<br> community-dwelling older adults, who volunteered as an informant for usability testing<br> and research. In the course of database enrollment, they participated in a usability<br> test for an automatic coffeemaker, as a demonstration of activities in CUAR. In this<br> article, we analyzed data of 170 people aged 60 and over, for examining relationships<br> between results of usability testing of a coffeemaker and database items which includes<br> demographics information, test results of cognitive aging (e.g. MMSE, AIST-CAT),<br>and subjective evaluation on difficulty of artifacts usage. The results showed the in-<br>dependence between two errors, which were observed in over 25% participants, and<br> also errors and the task accomplishment, indicated by statistical independent and also<br> by comparing the lists of effective items in database. Some research questions which<br> should be pursued for cognitive aging and usability research.
