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)
The paper gives insight into main fields of analysis and synthesis of human motion in the recent years or into the works that are still under development. After general introduction half to one page of description is provided for each topics. Simple explanations are omitting theoretical details and rather each use one to two pictures to provide quickly(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)
The paper proposes stepping in place (SIP) as a modality of lower-extremities training in virtual reality. 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(More)
We investigated the effects of combining the visual and haptic modalities on the adaptation capabilities of healthy subjects to the virtual environment. The haptic feedback was provided by the actuated gait orthosis Lokomat programmed with stepping movements employing an impedance control algorithm. The visual cueing (only the reference motion is presented)(More)
