Sensor based utterance interpretation system SAR for communication robot

This study develops a dialog system named SAR for communication robots. SAR employs robot\´s sensor information to accept oral commands from users. There is a difficulty for the robots to deal with the oral commands because humans frequently use an anaphoric expression or an abstract expression. SAR succeeds in interpreting these expressions based on the obtained sensor information. For example, SAR could interpret Japanese anaphoric expressions such as "KOTTI MUITE (look at me)". Moreover, SAR could interpret an abstract expression such as "MOUSUKOSHI SUSUME (move further)".
