Real-Time Avatar Feedback in Virtual Reality Exercise

Poland28 participantsStarted 2024-05-06

Plain-language summary

The goal of this study is to examine whether real-time feedback provided by a virtual trainer avatar during virtual reality (VR) exercise influences participants' exercise well-being and movement accuracy. The study also aims to compare different types of feedback delivered by the avatar. The main questions this study aims to answer are: Does real-time avatar feedback improve exercise well-being during VR-based training? Does real-time avatar feedback improve movement accuracy during exercise? Are there differences between no feedback, verbal feedback, and combined verbal-gestural feedback? Researchers will compare three VR exercise conditions: no feedback, verbal feedback, and combined verbal-gestural feedback, using a randomized crossover design so that each participant experiences all conditions. Participants will: Take part in three VR exercise sessions, each lasting approximately 15 minutes Complete the sessions under different feedback conditions, with the order randomized Perform guided physical exercises while wearing a VR headset and following a virtual trainer avatar Provide self-reported ratings of exercise experience after each session This study is an interventional, randomized crossover trial conducted in adults, with all procedures completed during a single study period.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.

What they're measuring

Exercise Accuracy Index (EAI) based on motion tracking during VR exercise

Timeframe: During each VR training session across fourteen moderate-intensity exercises (up to three sessions per participant); not assessed during inter-exercise rest periods or during the final low-intensity cool-down exercise.

Exercise Well-Being

Timeframe: Immediately after each VR training session via computer-assisted web-based questionnaire (CAWI), up to three sessions per participant.
