Experience of Youths and Older People With Virtual Reality Games for Cognitive Assessment: Inductive Thematic Analysis and Insights for Key Stakeholders (Preprint)

Abstract

BACKGROUND Virtual reality (VR)–based goal-oriented games for cognitive assessment are rapidly emerging and progressively being used in neuropsychological settings. These games have been validated quantitatively, but minimal qualitative insights from users currently exist. Such insights on user experience are essential to answering critical questions linked to the games’ large-scale usability, adoption in hospital settings, and game design refinement. Current qualitative studies on these games have used general questionnaires or web-based reviews to answer these questions, but direct observation from primary settings is missing. We believe that direct observation of participants playing these games and subsequent interaction with them is critical to developing a more objective, clear, and unbiased view of the games’ efficacy, usability, and acceptability. OBJECTIVE In this study, we aimed to extract constructive and relevant insights directly from the participants who played VR-based goal-oriented games. We used these insights to answer vital questions linked to the practical utility of VR-based cognitive assessment. On the basis of these results, we also aimed to provide actionable insights to key stakeholders in the field, such as researchers, game developers, business personnel, and neuropsychology and allied professionals. METHODS Interview data from 82 younger (aged 18-28 years) and 42 older adult (aged >60 years) participants were used. The interview data were obtained from the 2 pilot studies we conducted on VR games for cognitive assessment. Inductive thematic analysis was conducted on the interview data, and later, the findings were carefully interpreted to develop implications for the key stakeholders. RESULTS We identified 5 themes: ergonomic issues, learning and training, postgame effects, game feedback, and system purpose. Regarding hardware, headset weight, adjustment straps, and controllers need to be improved to promote easy use of the device. Regarding software, graphics quality, immersion experience, and game mechanics are the primary deciding factors for a positive user experience. The younger group prioritized purpose and utility for long-term use, whereas the older participants cherished the entertainment aspect. Researchers and game developers must conceptualize and develop games that can provide maximum insights into real-world abilities. Manufacturing businesses need to improve the headset and accessories to make them more user-friendly. Finally, neuropsychology and allied practitioners must identify strategies to engage and train the participants to try VR-based cognitive assessment games. CONCLUSIONS VR-based games for cognitive assessment are promising tools to improve the current practices of neuropsychological evaluations; however, a few changes are required to make the overall user experience enjoyable, purposeful, and sustainable. In addition, all the key stakeholders need to focus on meaning and purpose over the hype of VR and are advised to work in synergy.
