Our state-of-the-science research facility contains cutting-edge equipment, now including an immersive virtual reality system consisting of a 4k wide-angle projector and a 180-degree spherical screen. The immersive virtual reality system allows full control of the visual scene to investigate the role of visual information during standing and walking. The visual screen surrounds a fully instrumented, split-belt treadmill. The split-belt treadmill can operate in belt-driven or subject-driven mode, the latter using measurements from the motion capture system to adjust belt speed and maintain the subject in the center of the treadmill during walking. The motion capture system is a 9-camera Vicon motion capture system for measurement of 3D kinematics. Auxiliary digital inputs/outputs allow synchronized integration with external devices, such as galvanic vestibular stimulation (GVS) and electromyography (EMG). Installed directly over the treadmill is a safety harness to prevent falls.
