Virtual Reality

Generating designs using virtual reality technology can greatly reduce prototyping design and testing costs and overall product development time. Over the course of the past few years there has been a rapid increase in the application of virtual reality applied science for diagnostic purposes, treatment, education, and study. Virtual tomography integrates three-dimensional imaging internal body structure from multiple CT or MRI scans with a simulated kinesthetic interface to help in diagnosis and healing. In endovascular simulation, a head mounted display superimposes three-dimensional scans on the patient's skin to guide the placement of implantable devices within blood vessels.

Virtual reality is used for medical instruction and study. With virtual visual and kinesthetic systems, interns and residents can find out how patients with unusual conditions look, feel, and respond to curement -- absent the hazards of harming real patients. Advanced haptic systems enable physicians-in-training to not only see experts at work, but also to move their hands in tandem with the recorded motions of expert practitioners. In medical study, virtual reality is used for modeling molecules and drug design, gene modeling and direction, and other virtual biology uses. Linked page virtual reality enhanced surgery also gives information on this.

Virtual Reality (VR) may be used for athletics in different ways. First, VR can provide enhanced training and instruction for taking part in conventional sports. Second, VR can improve non-participatory involvement in conventional sports that spans, but is limited to, watching. Third, VR can make possible new virtual things for traditional sports or entirely new athletics within virtual environments.

Sound is a major part of virtual reality. As humans have two eyes for vision, people have two ears for hearing. As with vision, one's brain puts together two spatially separated sensory signalss to make three-dimensional inferences about the signal source. It determines three-dimensional location and motion by the source by evaluating: the delay between when each ear hears the sound; level and changes of sound frequency and volume; alteration of sound wave features caused by obstacles; and sounds bouncing off surrounding surfaces.
