VR Motion Guidance System — Master's Thesis
Overview
Designed and built a VR motion guidance system for upper-body rehabilitation on Meta Quest, integrated into the MediHopps telerehabilitation platform. The system provided real-time corrective feedback, hybrid feedforward guidance, and an onboarding flow to support unsupervised training sessions.
Key results
In a study with 11 participants, the system reached a usability score of 80.9 (SUS), with strong playability and motivation ratings. I introduced a new metric, the Stability-Adjusted Time Efficiency Score (SATES), to evaluate performance across exercises and track improvement both within and between sessions. Despite limitations in Quest’s body tracking, participants remained engaged and motivated, showing that such a system can support long-term rehabilitation adherence.
Role & ownership
Took complete ownership end-to-end: from defining requirements and designing the architecture, to implementing the system in Unity, running the user study, and analyzing results.
