We present a new tactile display for use in dexterous telemanipulation and virtual reality. Our system renders the location of the contact centroid moving on the user’s fingertip. Constructed in a thimble-sized package and mounted on a haptic force-feedback device, it provides the user with concurrent feedback of contact location and interaction forces.We believe such a design will enable more ...

Abstract In thermal power units, superheater outlet temperature is a very important parameter, but because of its long delay time and large inertia, it difficult to obtain good control effect by traditional algorithm. this paper, taking supercritical once-through boiler as the research object, combined with established superheated steam object model, two-degree-of-freedom system based on VRFT d...

FUNCTIONS OF INFORMATION DISPLAYS ometric appearance of a real environment by visually presenting static and dynamic features as if the viewer were to be actually looking at them. A viewer looking at such an image can thus interpret the image as if it represented a virtual space on the far side of the picture plane. Vehicle instrument panels, road signs, warning placards and maps are all exampl...

along with the advent of recent communicative technologies, new cyber social networks have been emerged as the most influential line of interaction. this is a new world free from many of constraints and limitations of the physical world. it lacks weather, gravity, and geographical features; therefore it does not require addressing many of structures and necessities of the real world. in the vir...

Vision allows for obstacle detection and avoidance. The compensatory mechanisms involved in maintaining these functions in blind people using their remaining intact senses are poorly understood. We investigated the ability of congenitally blind participants to detect and avoid obstacles using the tongue display unit, a sensory substitution device that uses the tongue as a portal to the brain. W...
