Virtual Reality Player

Sophisticated virtual reality systems still tend to be complex, expensive, and cumbersome. However, with advances in computing power and more compact VR hardware, one can expect eventual commercialization of VRD players following the successful distribution of two-dimensional DVD and CD players. Computer recognition of hand and facial gestures currently happens 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 motion by the one's hands and face. This integrates conceptual components from anatomy, kinesiology, and human biovisual processing. Human gestures can be measured via computer via a mechanical glove or indirectly via the optical analysis of motion pictures. There is a great deal of potential for further development of optical monitoring of lip, facial, eye, head, hand, and body motion. Significant obstacles remain. Computers cannot currently track things that are obscured from the line of sight by other objects, insufficiently lit, or too challenging. Future progress concerning methods to translate optical pictures into virtual three-dimensional things should create opportunities for much greater precision in optical monitoring of human movement. methods of haptic feedback may also be of interest.

Virtual Reality is already a multi-billion-dollar field with applications in entertainment, information analysis, design, medicine, robotics, trade, direction, military, real property, travel, dating, sports and instruction. Multiple factors will probably further accelerate growth in elementary VR technology and expand its use to diverse industries. Evolutionary and revolutionary (e.g. nanocomputing, holotechnology computing, living and quantum computing) advances in computing will enhance the performance and drop the cost of Virtual Reality (VR) systems available commercially and the general population. Disruptive technological advances in computer-assisted sight and computer-brain connections will probably lead to next-generation image projection systems without shutter glasses and accompanying sickness. Progress in the field of telerobotics will increase demand for high-quality VR-based interfaces for human operators. For VR related information, please also see virtual reality and computer vision .

Current 3D imaging systems often use simulated motion parallax, intersecting things, aerial perspective, shading and lighting to lead people to perceive images three-dimensionally. Future 3D imaging systems might be able to make actual, travelling 3D things using moving holotechnology pictures using micro-mirror arrays. The site on advanced interactions and virtual reality has more developments on virtual reality.

The essence of virtual reality is fooling the human body into perceiving things that are only simulated. From this perspective, it is no surprise that the human body can respond negatively, especially when it gets conflicting impulses from different senses and is not totally fooled. With respect to vision, a limitation of today's VR imaging systems is disharmony between eye focus (adjusting the lens of each eye at the apparent distance of the object viewed) and eye axial convergence (coordinating the orientation of both eyes to cross lines of sight at the perceived distance of the object). This problem is more serious for head mounted image display systems in which images are displayed relatively near to one's eyes. Another problem is latency (lagtime) between the kinetic motion signals that the brain gets from the inner organelles of one's ear and the visual movement signals that the brain gets from one's eyes. In the event of a lag in visual image processing, then the body receives impulses of movement from kinetic senses in rapid-response but signals of motion from vision after lag time.
