In the area of advanced multi-modal telepresence (telemanipulation) or virtual environment applications, the haptic modality has received increasing attention in recent years. In addition to multimedia (3D stereo graphics and 3D acoustics) the haptic modality ? comprising the human kinesthetic, tactile, and temperature senses ? is one of the most important modalities in human system interaction because of the strong physical coupling of the human operator to the system. Kinesthetic feedback devices are interfaces allowing force and torque feedback to human operators. These forces and torques are usually measurements from remote teleoperator environments or are computed in virtual reality haptic rendering engines as the result of virtual objects interacting with each other. Haptic interfaces have been successfully used in various application domains, e.g. telesurgery, medical and surgical virtual reality systems, rehabilitation, tele- and micromanipulation, telemaintenance, virtual protoyping, scientific visualisation, and education. In order to offer a haptic device allowing high force tasks in large volumes the Institute of Automatic Control at the Technische Universit?t M?nchen designed the hyper-redundant haptic display ViSHaRD10 (Virtual Scenario Haptic Rendering device with 10 actuated DOF), which is used in combination with virtual reality and telepresence applications. To give the human operator the impression of operating in a remote or virtual environment this device is additionally combined with a head mounted display.
