Bridging game metrics and user perception in remote virtual reality exergames: Lessons from a COVID-19 home-based...

Area of Science:

• Gerontology
• Human-Computer Interaction
• Exercise Science

Background:

• Virtual reality (VR) technology is becoming more affordable.
• VR exergames offer potential for promoting physical activity and engagement in older adults.
• Limited understanding exists on how VR game metrics and user experience data influence long-term adherence.

Purpose of the Study:

• To examine the feasibility of a custom VR exergame, "Seas the Day," for at-home use by older adults.
• To assess the evolution of VR-generated game metrics and user experience over time.
• To understand factors influencing long-term adherence to VR exergames in older adults.

Main Methods:

• Thirteen community-dwelling older adults participated in 18 seated VR sessions over 6 weeks.
• Activities included Tai Chi, rowing, and fishing simulations.
• In-game metrics (e.g., repetitions, response times, errors) and a difficulty-adjusted performance index (DAPI) were recorded. A Game User Experience Scale was administered at weeks 3 and 6.

Main Results:

• Most participants demonstrated improving or stable performance, with notable gains in Tai Chi completion time, rowing efficiency, and fishing response times.
• The difficulty-adjusted performance index (DAPI) indicated overall upward performance trends.
• Game User Experience ratings remained high, particularly for enjoyment and ease of use, suggesting sustained engagement.

Conclusions:

• Custom VR exergames are feasible for promoting physical activity and engagement among older adults in home settings, even during social restrictions.
• Game metrics and user experience data provide valuable insights into feasibility, adaptability, and individualized progress.
• VR exergaming holds potential for promoting well-being, highlighting the need for personalized engagement strategies.
