Resumo

Introduction: Left-Right Confusion (LRC) is a difficulty that may persist into adulthood, yet it remains underexplored in the literature. Exergames present a promising approach, as left-right learning involves body awareness and motor response. Objective: This paper presents the design, development, verification and utility evaluation of a serious exergame created to mitigate LRC. Methodology or Steps: The game was designed using PEED and MOLDE methodologies, supported by a literature review, and involved the participation of 24 domain experts. The game was implemented in Unity and uses MediaPipe for motion capture. Utility was assessed with the SEU-Q v2 questionnaire. Results: The game met all mandatory and most desirable requirements identified during the design process. In the utility evaluation, it achieved mean scores of 4.27/5 from the player perspective and 4.52/5 from the professional perspective, with an overall mean of 4.40/5. Qualitative data converged with quantitative findings. These results indicate that the game is perceived as useful, safe, and engaging, with potential to address LRC.
