We present work in progress on a tele-immersion system for telerehabilitation using real-time stereo vision and virtual environments. Stereo reconstruction is used to capture user's 3D avatar in real time and project it into a shared virtual environment, enabling a patient and therapist to interact remotely. Captured data can also be used to analyze the(More)
This study proposed virtual reality (VR) as a modality of lower-extremities training. A kinematic model of a human body and a corresponding virtual figure were developed, in order to visualize the movements of the subject in a real-time virtual environment on a large display, which represented a virtual mirror. An optical system with active markers was used(More)
We compared the effects of visual and haptic modalities on the adaptation capabilities of healthy subjects to the virtual environment. The visual cueing (only the reference motion is presented) and visual feedback (the reference motion as well as the current tracking deviation are presented) were provided by a real-time visualization of a virtual teacher(More)
A four degree-of-freedom (DOF) robotic mechanism can be used to manipulate objects in six DOF by using a gripper altered for two-point pivot grasping where the force of gravity is used for six DOF reorientation. We show that one pivot grasp is sufficient to rotate an ashlar-shaped object from known initial stable configuration into arbitrary final stable(More)
