Abstract

Training a myo-electric prosthesis could benefit from a virtual reality environment (VRE) as a training tool, however it should match the wishes and needs of prosthesis users and therapists. We investigated whether an existing VRE, developed for exploration of prosthesis use, complied with the needs and wishes of the end-users, regarding control and feedback. The VRE simulated a coffeehouse where different types of cups of coffee needed to be grasped. A preliminary sample of eight prosthesis users and eight therapists tried out the VRE and subsequently filled out a 7-item numeric rating scale questionnaire. Prosthesis users were not very satisfied with the control in the VRE, mainly due to the delay between the muscle impulse and the prosthesis movement. Therefore, they felt that the control did not correspond to a daily life experience with their own prosthesis. End-users agreed that sparse visual feedback was used and, then, only when needed. Negative feedback was however present in the game, which was only noted by therapists. Prosthesis users and therapists agreed with most items of the questionnaire, indicating that they experienced most factors of the framework in the VRE. However, the observed differences in experiences between end-users showed that both prosthesis users and therapists should be involved in the assessment of training tools.
