simulating physical contact with objects in virtual environments

When simulating the sensation of touch, Virtual Reality systems must simulate the tangible resistance that virtual things would have on human movement as if they were real. This resistance may be transmitted to one's body though multiple mechanical rods and levers, air cushions, or electro-magnetic devices imbedded in glove or body tights. Simulation of touch and movement through such machines is known as "haptics." Although kinesthetics technology currently is less advanced than computer to human interaction through vision and audio signals, it will probably become more common with technological advances. Related technologies at Virtual Reality may be of use.

The most prevalent sound-based communication from people to computing systems is voice interpretation. Speech interpretation applied science has made considerable progress independently of Virtual Reality. The application of advance voice recognition systems to virtual reality significantly improves the scope and realism of the communication between humans and computers. Virtual Tours Grand Prairie, Texas also deals with these concepts.
