We have been developing and researching chat robot for elderly people. This paper proposed category estimation for voice based chat robot system. Proposed method estimates a category of the user's utterance sentence. Category or topic estimation have been studied by many researchers, however voice base chat system needs a quick response. Therefore our system is simple method just using keyword match...
This paper shows acquiring personal keywords and using them for human-robot communication or supporting to human-human communication. Personal keywords are feature of personality. Proposed system acquiring the keywords from a conversation. Authors developed a prototype of the keywords based communication system. First experiment acquired the keywords from the 2 trial conversations and set up the robot...
Robot therapy is expected to have psychological, physiological, and social effects similar to those of animal therapy. The therapeutic seal robot, PARO, is used in various facilities for the elderly, and its use spreading throughout the world. In previous studies, the effects of PARO were examined by various types of tests. However, the number of subjects in those studies was low. In this study, PARO...
Brain activity during interaction with seal robot “Paro” was measured by functional near-infrared spectroscopy (fNIRS). In the pilot study, there were two experimental tasks: Interaction with Paro that was switched ON (Paro ON) and Paro that was switched OFF (Paro OFF) with one minute rest before and after the tasks. The results showed significant activations around the pre-motor area and the supplementary...
