Designing Immersive Virtual Reality Environments for Supporting Patients at Home

Translating Input From Home Care Nurse Experts to Design Requirements

Abstract

Immersive virtual reality computer programs provide new experimental and treatment interventions that hold great promise for nursing. Immersive virtual reality uses sensory cues to represent real-world environments in a way that makes participants feel as if they are in a physical space different from the one in which they currently exist. As the acceptance of immersive virtual reality as a clinical and experimental tool has grown, so has the need to ensure that the context depicted in the environment mirrors both the sensory and the task requirements of the real-world situation. Here, we describe the use of nurse expert key informant group interviews to generate requirements that must be fulfilled in immersive virtual reality environments designed to evoke and engage participants in self-management tasks. An expert panel of four home care nurses participated in three sessions designed to elicit details of common home care challenges, frequency of variation, and typical participants. More than 20 potential scenarios were identified. The design team later used this information to create design requirements for two key scenarios and subsequently develop immersive virtual reality environments for use in research studies, mapping sensory and functional expectations to immersive virtual reality implementations. Challenges in mapping from key informant group findings to requirements are addressed.
