Abstract
The aim of this study was to design user-friendly off-line human–robot interactions based on a telephonic conversation database (TCD), and to provide the elderly living alone independently (ELAI) with psychological support. A TCD was established based on phone calls to 170 ELAI, made once every 2 weeks for 10 years. Based on the TCD, conversation flows were continuously analysed through a Question–answer-response format, which was centred on 366 ordinary topics, 291 physical topics, and 322 psychological topics. Usability was evaluated in a trial involving 15 ELAI in their homes over a 4-to-8-week period. Their emotional states were evaluated using the Profile of Mood States (2nd Edition Short Form) and Functional independence measure (FIM) pre- and post-trial. Eighty-seven per cent of the participants indicated that the robots helped them in their daily lives. A close examination of the changes in all participants showed statistically significant improvements in mood and 3 out of 5 FIM cognitive items. Eighty-seven per cent of study participants wished to continue the experiment. We determined that the communication robots, in conjunction with the TCD, improved the psychological well-being of the ELAI.
