In the haptic rendering system that allows the force display of complex deformable objects, the coherence remains difficult because of the different refresh frequencies necessary for real-time haptic display and realistic visual display. In this paper, a time series based predict method is proposed to extrapolate the force computed by the deformable model to go beyond interactively to haptic real-time...
A new softness display system has been developed which is based on the principle of deformable length of elastic element control (DLEEC). In this system, operator can feel the softness of the virtual objects with the softness display device. Compared with other haptic device, the device is passive and exert the react force only when the operator "actively touch" the virtual objects. The...
In this paper, it is proposed that a new design of texture haptic display system consisting of a rotating cylinder that evokes a virtual touch sensation of texture surfaces contacted to the user's finger. Small holes, which simulate different surface texture with different rotating speed, are drilled on the cylinder made of aluminum alloy. The user places his or her finger on a small window and moves...
