Strong adaptability is a major requirement and challenge in the physiotherapeutic use of motion-based games for health. For adaptation tool development, tablets are a promising platform due to their similarity in affordance compared to traditional clipboards. In a comparative study, we examined three different input modalities on the tablet that allow for configuring joint angles: direct-touch, classic interface components (e.g. buttons and sliders), and a combination of both. While direct touch emerged as the least preferable modality, the results highlight the benefits of the combination of direct-touch and classic interface components as the most accessible modality for configuring joint angle ranges. Furthermore, the importance of configuring joint angles along three distinct axes and the interesting use-case of configuration tools as communication support emerged.
