Abstract
This paper describes the implementation of a Multimodal Guidance System (MGS) for upper limb rehabilitation through vision, haptic and sound. The system consists of a haptic device that physically renders virtual path of 2D shapes through the point-based approach, while sound technology provides audio feedback inputs about patient’s actions while performing a manual task as for example: starting and/or finishing an sketch; different sounds related to the hand’s velocity while sketching. The goal of this sonification approach is to strengthen the patient’s understanding of the virtual shape which is used in the rehabilitation process, and to inform the patient about some attributes that could otherwise remain unseen. Our results provide conclusive evidence that the effect of using the sound as additional feedback increases the accuracy in the tasks operations.
