Virtual Trade

The scope of virtual trade has expanded to include not only stock trading, but also almost every form of buying and selling goods and services. The applied science of Virtual Reality (VR) is still in its infancy, but is evolving promptly. Currently, the base-line criteria for virtual reality have artificial creation of 3D vision through a head-mounted VR display, monitoring of hand location and direction to handle artificially constructed things such as by a motion-measuring glove, and sound that reasonably corbehaves to parts in the fabricated construct. Simple simulated touch -- for example, by a configuration-monitoring glove is more and more common. In any event, this is still not required to meet the base-line definition of virtual reality. Also, virtual commerce has information about this VR topic.

Computer interpretation of hand configurations and facial expressions is already underway and will probably lead the development of optical information transmission from humans to computers. Gesture interpretation is based on computer processing and three-dimensional modeling of the structure and movement of the human hands and face. This integrates conceptual components from anatomy, kinesiology, and human vision. Human gestures can be recorded through a computer directly through a mechanical glove or indirectly through the optical processing of video images. There is a great deal of potential for advanced development of optical measurement of lip, facial, eye, head, hand, and body movement. Significant obstacles remain. Computers cannot now monitor components that are obscured from the line of sight by other objects, insufficiently lit, or too complex. Future generation development of methods to translate optical pictures into virtual 3D objects should open the door for much greater precision in optical monitoring of body movement. Link to methods of haptic feedback provides further information.

Virtually-enabled telerobotics is used in to make possible humans to perform work in dangerous environments such as: outer space; areas with chemical or biological hazards; combat zones; oil fields; and under the sea. Virtually-enabled robotics can also help in large-scale activities (such as mining, earthmoving, and architecture) and small-scale activities (especially surgery on a micro-scale, nanomanfacturing, genetic applied science and virtual biology). Virbots are used for computer world uses. For additional perspective, you may wish to visit virtual reality and navigation .

Shutter glasses are one mechanism to present alternate images to one's eyes. These glasses first block the image to one eye at a time, timed with two different perspectives alternatively shown on a screen. When the alternating perspective pictures are displayed in sufficiently quick order, then the brain integrates them into a single 3D picture. head mounted displays frequently have some type of shutter glasses as part of a helmet and graphic displays that are somewhat near to the eyes. The close screen displays make it easier to cover much of the field of vision (e.g. over 60 degrees), but requires very high-clarity imaging. The head device might be: part of an armature for following head movement; or physically unconnected with motion of one's head tracked by optical, magnetic, or ultrasonic monitors.
