Impressions made by blinking light used to create artificial subtle expressions and by robot appearance in human-robot speech interaction

Abstract: The impressions made by a blinking light used to create artificial subtle expressions (ASEs) and by a robot's appearance on users were investigated. The blinking light, which shows the user that the robot is performing speech recognition and thereby prevents utterance collisions, was separated from the robot by embedding it in a pedestal unit. In an evaluation experiment, participants performed five tasks with a spoken dialogue system coupled to a robot placed on the pedestal. The participants' impressions of … Show more

“…To correctly convey the states of the robot when it listened and spoke, we first determined the robot's lighting feedback pattern in the previous studies [32,35,57]. When the robot was listening to a person, the two light-emitting diodes in the robot's eyes flashed in a fixed on-off pattern over 2 s at a frequency of 15 Hz [35] (Figure 2), which was the most acceptable frequency.…”
