VRGaitAnalytics: Visualizing Dual Task Cost for VR Gait Assessment
summary
A low-cost VR gait lab uses HTC Vive Pro with Vive trackers to record foot kinematics and a dual-task paradigm where participants memorize numbers while walking with anticipated or random virtual obstacles. Real-time metrics (velocity, step length, step width, crossing success) and side-by-side trial comparison playback let experimenters spot that high cognitive load shortens step length and increases step width; a feasibility study with therapists and students finds the system usable and clinically relevant.
