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.
