Therefore both the on-screen and the robotic agents could express the same behaviours. Fig. 2. On-screen agent RoboStudio2 by NEC Corporation left robotic agent PaPeRo3 by NEC Corporation right . Fig. 3. Experimental Setting. 2 http product robot 3 http products robot intro 88 Human-Robot Interaction Participants The participants were 20 Japanese university students 14 men and 6 women 19-23 years old . Before the experiment I ensured that they did not know about the PaPeRo robot and RoboStudio. They were randomly divided into the following two experimental groups. Screen Group 10 participants The on-screen agent appeared on a 17-inch flat display The agent on the screen was about 15 cm tall and talked to participants. The agent s voice was played by a loudspeaker placed beside the display. Robotic Group 10 participants The robotic agent It was about 40 cm tall talked to participants. Both the robotic agent and the computer display on-screen agent were placed in front of and to the right of the participants and the distance between the participants and the agents was approximately 50 cm. The sound pressure of the on-screen and robotic agent s voice at the participants head level was set at 50 dB FAST A . These agents voices were generated by the TTS Text-To-Speech function of RoboStudio. The overview of the experimental setting is depicted in Fig. 3 and pictures showing both experimental groups are shown in Fig. 4. Fig. 4. Experimental Scene participants in Screen group left and in Robotic group right Procedure First the dummy purpose of the experiment was explained to the participants and they were asked to play the picross game for about 20 minutes after receiving simple .
