Resumen

The use of virtual rehabilitation systems for upper limbs has been implemented using different devices, and its efficiency as a complement to traditional therapies has been demonstrated. Multimodal systems are necessary for virtual rehabilitation systems since they allow multiple sources of information for both input and output so that the participant can have a personalized interaction. This work presents a simplified multimodal contactless architecture for virtual reality systems that focuses on upper limb rehabilitation. This research presents the following: 1) the proposed architecture 2) the implementation of a virtual reality system oriented to activities of daily living, and 3) an evaluation of the user experience and the kinematic results of the implementation. The results of the two experiments showed positive results regarding the implementation of a multimodal contactless virtual rehabilitation system based on the architecture. User experience evaluation showed positive values regard to six dimensions: perspicuity=2.068, attractiveness=1.987, stimulation=1.703, dependability=1.649, efficiency=1.517, and novelty=1.401. Kinematic evaluation was consistent with the score of the implemented game. © (2023), (Science and Information Organization). All Rights Reserved.
