In this study, a companion robot system for older adults was developed, and 18 older adults from an elderly care center in Central Taiwan were recruited. Based on the results, the participants thought that the system would improve their lives and that they were willing to immerse themselves in the use of the system. However, it was difficult to use. They held different opinions on its perceived ease of use. The older the participants were, the less their perceived ease of use was. The main reason for this might have been the fact that these older adults were not good at speaking Chinese and English, and that they were also hard of hearing.
