Immersive virtual reality in older people: Case study

Abstract

Background: The use of Immersive Virtual Reality (IVR) is booming in all age groups. However, some structural problems have limited its application in more fragile groups. Objective: Analyze the safety, usability and experiences of IVR in older people. Method: 4 males (2 parkinsonian and 2 healthy, 57-78 years) participated in the study. They conducted an RVI session (10-15 minutes) with a Head-Mounted Display (HTC Vive Pro) device. The safety of immersive experience (SSQ), system usability (SUS) and impressions after experience (GEQ and an ad hoc satisfaction questionnaire to identify strengths and weaknesses of the tool) were evaluated. Results: Everyone completed the session successfully, without adverse effects. The usability of the system was good, even overcoming obstacles such as the presence of vision corrective glasses and hearing aids. The opinions after the session pointed out the positive experience and all showed their willingness to repeat it, describing it as entertaining, fun and useful. Conclusion: The successful use of the RVI in the cases presented opens the door to future research with clinical trials that can evaluate the improvements of physical, psychic and social variables in the Spanish senior population.
