This paper reports an evaluation practice of an information display for persons with dementia. Developed device to inform time of daily meals was installed at a group home and four month user test was carried out. 88 year old female who often asks time of meals repeatedly was chosen as a subject. Voice and image data were collected to analyze the information acquisition of the user. As a result of speech and behavior analysis, percentage of successful information acquisition was increased from 50% to 100% after the intervention. Meanwhile, the percentage of information acquisition by asking people was reduced from 100% to 43% against the increase of using the device. Therefore, proposed display methods would be also useful for people living alone at home, and have promising potential to reduce care giver burden. As the user got accustomed to using the device in progression, even persons with severe memory disorders are considered to be capable of adapting new device by taking time. Application of vivid colors was also found to be helpful to call attention to the information. These results indicate that speech and behavior analysis is effective in evaluation of devices concerning cognitive functions and suitable for persons with dementia as the data can be collected in the context of daily living.
