Questionnaire experiment using networked service robots

Abstract

We have developed a questionnaire system using networked service robots. Each robot has a touch display to show the questions and answers. The touch data are transferred to a server PC, and the selected answer is displayed in real time. Conventionally, it has been difficult to discern the reliability of the response data. The robot system is not only visually appealing but also capable of obtaining reliable data using additional information such as answering time, pressure, and facial expression. We conducted the experiment and analyzed the results of the answers based on the response time. In this paper, we explain the system and the results.
