The " Bubble " technique is a novel interaction technique to interact with large Virtual Environments (VE) using a haptic device with a limited workspace. It is based on a hybrid position/rate control which enables both accurate interaction and coarse positioning in a large VE. The haptic workspace is displayed visually using a semi-transparent sphere(More)
Today, most haptic devices are designed for desktop applications. Therefore, when dealing with human-scale virtual environments, haptic interaction usually remains limited to only a small portion of the virtual world. This paper describes novel technologies aimed at addressing this issue. We investigate hardware solutions, with the design of devices(More)
This paper describes a new interaction technique called haptic hybrid rotations to overcome the physical angular limitations of force-feedback devices when manipulating virtual objects. This technique is based on a hybrid control of the object manipulated with the device. When approaching the angular mechanical stops of the device, the control mode switches(More)
This paper describes an experiment that was conducted to evaluate three interaction techniques aiming at interacting with large virtual environments using haptic devices with limited workspace: the Scaling technique, the Clutching technique, and the Bubble technique. Participants were asked to paint a virtual model as fast and as precisely as possible(More)
This paper describes two psychophysical experiments which were conducted to evaluate the influence of the ControlIDisplay (CID) ratio on the perception of mass of manipulated objects in Virtual Environments (VE). In both experiments, a discrimination task was used in which participants were asked to identify the heavier object between two virtual balls.(More)
"RoboGamer" is a robotic system which is able to play a video game togather with a human player. In previous computer game systems, the computers are always designed as enemies to the human. However, in this project, we realized a physically connected friendly computer player by a simple robotic system that is composed of a video camera, wire based force(More)
