Addressing user experience and societal impact in a user study with a humanoid robot

摘要

Abstract. Using a preliminary exploratory case study the presented work investigates the feasibility of methods for the evaluation of user experience factors in human-humanoid interaction as well as measurements of societal impact in user studies. The case study is based on two tasks participants had to perform with the HRP-2 robot. The robot was controlled by the participants via speech commands to pick up (task1) and put down (task2) an object onto another place. Main goal of the case study was to explore the methodological concept on how to measure novice users ’ experiences during the collaboration with the humanoid robot HRP-2 via speech commands and if the general attitude towards robotics changes because of the interaction with the robot. To address users ’ experiences during the user study, participants were asked after each task to state their thoughts and feelings they had during the interaction (retrospective think aloud). Furthermore, participants were interviewed by means of two validated standardized questionnaires (NARS and AttrakDiff) and an especially developed questionnaire. The preliminary results show that retrospective think aloud is a good way to gather qualitative data on users ’ experiences. Furthermore a final interview on societal impact of humanoid robots gave insights into how novice users imagine a future society with robots. 123 1
