Impacts of Robot Learning on User Attitude and Behavior

User Perception of Teachable Robots: A Comparative Study of Teaching Strategies, Task Complexity and User Characteristics

“…-Personality: We measure five personality traits (Neuroticism, Extraversion, Openness, Agreeableness, and Conscientiousness) by using the Mini-IPIP, 20-item Likert scale [8]. -Robotic Prior Experience: We assess the participants' prior experience with robot through the robotics experience scale, 5-item Likert scale [18]. -Perceived Control: we measure the perceived control of participants over the robot by adapting a 3-item Likert scale from Delgosha et al [7].…”

“…-Testing phase: After visioning the training video, participants proceed to watch a sequence of four videos, in which the robot's performance is assessed across diverse environments of the same nature as the assigned task. Similar to [18], we consider different trajectories in the testing trials, encompassing two successful, one ambiguous and one failure. In the ambiguous trajectory, the robot actions may not optimal but ultimately lead to success.…”

“…All videos involving the experimenter training and testing the robot are demonstrated via a Wizard-of-Oz approach. This choice is made to maintain the failure and agent's performance consistent between the conditions [18]. The links to all videos can be found on the project website.…”

“…In a recent study [18], researchers investigated the influence of diverse teaching methods, including interactive Reinforcement Learning (RL), on users' perceptions of a care robot. Their findings highlighted a correlation between the level of anthropomorphism attributed to the robot and the extent of involvement in the teaching.…”

“…We conduct a comparative analysis of three teaching scenarios involving distinct teaching methods: Interactive RL from Evaluative Feedback, Preference-based RL, and a Download condition where the robot learns without a human intervention. The latter condition was inspired by the work of Moorman et al [18] and represents the control group of the study as no interaction with the robot is invovled. Figure 1 depicts the three teaching scenarios.…”
