Personalized Virtual Reality Environments for Intervention with People with Disability

Abstract

Background: Virtual reality (VR) is a technological resource that allows the generation of an environment of great realism while achieving user immersion. The purpose of this project is to use VR as a complementary tool in the rehabilitation process of people with physical and cognitive disabilities. An approach based on performing activities of daily living is proposed. Methods: Through joint work between health and IT professionals, the VR scenarios and skills to be trained are defined. We organized discussion groups in which health professionals and users with spinal injury, stroke, or cognitive impairment participated. A testing phase was carried out, followed by a qualitative perspective. As materials, Unity was used as a development platform, HTC VIVE as a VR system, and Leap Motion as a hand tracking device and as a means of interacting with the scenarios. Results: A VR application was developed, consisting of four scenarios that allow for practicing different activities of daily living. Three scenarios are focused on hand mobility rehabilitation, while the remaining scenario is intended to work on a cognitive skill related to the identification of elements to perform a task. Conclusions: Performing activities of daily living using VR environments provides an enjoyable, motivating, and safe means of rehabilitation in the daily living process of people with disabilities and is a valuable source of information for healthcare professionals to assess a patient’s evolution.

Enhanced Inclusion through Advanced Immersion in Cultural Heritage: A Holistic Framework in Virtual Museology

“…The IntARSI project leverages multisensory immersive solutions to accommodate diverse audience needs and emotions [20]. WalkinVR pioneers accessibility in virtual reality, allowing mobility-impaired users to engage in virtual reality games [21]. The user-centric ArkaeVision project offers virtual representations, utilizing a 3D environment to generate inclusive and customizable cultural experiences [22].…”

Virtual Reality and Metacognition Training Techniques for Learning Disabilities

“…In addition, trainers can develop virtual scenarios considering the skills to be taught by the subjects according to their abilities and needs. For instance, they can present social scenarios for developing daily living skills for people with autism [46].…”

Bridging the Gap: Virtual Reality as a Tool for De-escalation Training in Disability Support Settings

“…For instance, a study investigated a custom-built VR program to foster empathy in disability workers by immersing them in the first-person perspective of having an intellectual disability [27]. While there is a significant number of studies related to use with clients of disability support organizations [28][29][30][31][32], our study does focus on staff training.…”
