Can you help me to re-order a story? Design and development of a game-based activity with NAO for children

Social robots are increasingly being used in educational and therapeutic environments, particularly for children with neurodevelopmental disorders. This paper investigates the feasibility of using the NAO robot in a "Reorder a Story" scenario, where children help the robot reorder images to form a coherent narrative. The study aims to assess the technical feasibility, usability, and engagement of the system, as well as the reliability of its technical setup. Seventeen primary school children participated in the experiment, completing a series of tasks while interacting with the robot. The children's performance was evaluated based on the number of errors made during the game and their subjective perception of the experience. Feedback was measured using a Likert scale (1-10) and the Goodspeed Questionnaire's likeability domain (1-5). The results showed high levels of appreciation, with an average evaluation score of 9.59 ± 0.60 and an average likeability score of 4.98 ± 0.06. The average number of errors recorded during the game was 0.94 ± 1.30. However, younger children experienced difficulties, indicating the need for further adaptation of the task. Technical issues were observed, such as robot movement errors and overheating, which were addressed by repositioning the robot and introducing rest periods. These preliminary findings suggest that the NAO robot, delivering the "Reorder a Story" game, is a promising tool to be used with children. Future research should focus on expanding the sample size, including children with neurodevelopmental disorders, to better assess the clinical applicability and refine the system.
