Virtual Reality

Virtualability is the degree to which a virtual reality system realistically approximates the real world environment which it simulates. A major growth area for virtual reality applications is the field of medicine. Virtual reality is used in numerous ways for medical diagnosis, healing, instruction, and research. Virtual-reality uses help doctors to identify and extract malignant tissue. Medical robotics ("medibotics") with Virtual Reality (VR) interfaces enable microsurgical operations with more accuracy than traditional surgical methods. Virtual Tomography (VT) integrates multiple Computerized Tomography (CT) or Magnetic Resonance Imaging (MRI) images of internal organss with simulated kinesthetic interfaces. Endovascular physicians use three-dimensional scans to guide direction of various catheters inside blood vessels. virtual reality and psychological treatments covers more information along these lines.

We all connect with computers in a host of ways. For example, merely watching a screen and typing is an interface. Nonetheless, without the immersive, responsive, and sophisticated characteristics described above, these interactions do not meet the criteria for Virtual Reality.

Optics may also be used to track movement of humans. An elementary method of optical tracking involves fastening multiple lights to a glove or body suit and then tracking them three dimensionally, but this only tracks a limited quantity of points. Gesture recognition by computers currently happens. It involves computer modeling of the configuration of human hands and face -- drawing from the fields of anatomy, kinesiology, and sight perception. simulating physical contact with objects in virtual environments discusses additional information about these concepts.

Virtual Reality is being commonly used for aircraft navigation. The most well-known uses are VR systems for pilots that superimpose pictures of maps, navigational graphics, or targeting information shown on the horizon, other aircraft or the ground from a Head Mounted Display (head mounted display). Although air traffic controllers deal frequently with three-dimensional situations, VR uses to air traffic control systems are not widespread. Also in the aerospace field, but not navigation per se, virtual reality is used extensively for aircraft training. virtual home tours also has interesting notes on this topic.
