Real-Time Avatar Feedback in Virtual Reality Exercise

NCT07384065 · Status: COMPLETED · Phase: NA · Type: INTERVENTIONAL · Enrollment: 28

No results posted yet for this study

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.

Conditions

  • Healthy Participants

Interventions

BEHAVIORAL

VR Exercise With No Avatar Feedback

Participants perform a standardized exercise session in a virtual reality environment guided by a virtual trainer avatar. The avatar demonstrates the exercises but does not provide any real-time verbal or gestural feedback during the session.

BEHAVIORAL

VR Exercise With Verbal Avatar Feedback

Participants perform a standardized exercise session in a virtual reality environment guided by a virtual trainer avatar. Real-time motion data are analyzed by the VR system, and the avatar provides adaptive verbal feedback during the exercise session.

BEHAVIORAL

VR Exercise With Verbal and Gestural Avatar Feedback

Participants perform a standardized exercise session in a virtual reality environment guided by a virtual trainer avatar. Real-time motion data are analyzed by the VR system, and the avatar provides adaptive verbal and gestural feedback during the exercise session.
