Abstract (in Japanese) (See Japanese page) 
(in English) In the present study, human altruistic behavior was used to measure the robot ’s capability to express
emotional states by facial expressions. An experimental investigation with human participants with a tele-operation
setting in which two persons interact through a computer animated agent was conducted. A simple line-drawing
face was used in order to remove realistic, lifelike and biological human features from the agent ’s face. Participants
were asked to play the ultimatum bargaining game that is usually used to measure human altruistic behavior. All
participants were assigned to be the proposer and asked to decide their offer with in one minute. The corners of
the mouth of the line-drawing face moved up and down according to the amount of the offer. The results suggests
that facial expression change of a simple line-drawing face significantly affected altruistic behavior. Fifteen percent
larger amount of offers were yielded by showing contingent facial expression change.
