Abstract
Demands for robots which support our daily lives increase, and the communication ability is essential for such robots. Many researchers have been devoting their effort to develop various methods to understand languages, but perceiving the emotion of its conversation partner is also important for communications. Heart Rate Variability is expected to be useful for guessing human feelings, which is considered to be a method for measuring human psychological stress responses. In this report, we confirm the change of a physiological measure, Heart Rate Variability, during conversations with communication robots can be detected by using a pulse oximeter, which encourages to develop future application using sensing devices for physiological reactions.
