methods of haptic feedback

When simulating the macroscale characteristics of movement and touch, Virtual Reality (VR) systems must simulate the relative resistance that virtual things would exert on motion by parts of the body especially fingers, arms, and legs. For instance, if one lifts a virtual cube, then one's hand and arm must feel the relevant resistance so that the virtual cube to seem real. Pressure sensation may be transmitted from a computer to one's senses though micropressure machines (tiny pistons, inflatable bubbles, etc) powered by mechanical motors, magnetism, hydraulics, air, or other media. These micro-pressure devices can be integrated into hand devices, electronically-wired clothing, or gyroscopic armatures. Direct resistance from 3D fields might be possible in the future, but remains experimental. Haptic computer-to-human interaction will become widespread with technological advances, but it is presently less advanced than interaction through sight and hearing. Linked page ORI Applied Computer Simulation Labs also has additional information.

When you are planning a vacation or business trip, a virtual tour can give you a much better sense of what you will see at a destination than the information provided by an internet page with a few static, non-engaging pictures. Like virtual home tours, most virtually reality vacation tours are yet not totally 3D or enveloping, but they are increasingly responsive and moving toward more immersion. Virtual vacation tours have tours of cruise ships, resort hotels, cities and towns, parks and scenery and other tourist attractions. Virtual Tours Visalia, California also includes coverage of some of this material.
