Procedures and design Individuals who participated in the study gave written informed consent and then were sent to a reserved and quiet room to perform the tasks only in the presence of the researcher. The computer monitor was positioned on a table in front of the participants. The chair was adjusted in accordance with the size and need of the individual, with a footrest available if needed. For wheelchair users, their own wheelchair was used. After the necessary adjustments to perform the task, questionnaires and functional assessment scales were applied; then the researcher provided verbal instructions and performed a demonstration of interfaces according to each task (Kinect® for Windows, LMC® or touchscreen). Subjects were instructed to use the dominant hand (i.e., the least affected side) for all interfaces used during the game.
