Designing for physically disabled users: benefits from human motion capture – a case study
Résumé
Purpose: The present study aimed to improve the design of an interface that may help disabled children to play a musical instrument. The main point is to integrate human motion capture in the design process. Method: The participant performed 20 pointing movements toward four selected locations. A three one-way analysis of variance (ANOVA) was performed in order to determine the most efficient input location. For each button position, we compared (1) the reaction time (RT), (2) the movement time (MT), and (3) the spatial variability of the movements. Results: According to the results obtained for RT and MT, one position was the most efficient button location in order to produce efficient movements. Conclusions: As the case study showed, combining the 3D motion capture system and the statistical analysis led to help the designers their design methodology and crucial choices.
