Virtual Reality


Virtual reality is a simulated experience that can be similar to or completely different from the real world. Applications of virtual reality can include entertainment and educational purposes. Other, distinct types of VR style technology include augmented reality and mixed reality

Virtual Reality (VR) is the use of computer technology to create a simulated environment. Virtual Reality’s most immediately-recognizable component is the head-mounted display (HMD). Human beings are visual creatures, and display technology is often the single biggest difference

From visual simulation to virtual reality to games

Language tends to be seen primarily as a device for reporting on the nature of the world around us. This view engenders the default assumption that linguistic expressions normally refer directly to actual individuals and actual relationships in which they participate. But to

Virtual reality for the treatment of autism

Autism is a mental disorder which has received attention in several unrelated studies using virtual reality . One of the first attempts was to diagnose children with special needs at Tokyo University using a sandbox playing technique. Although operating the computer controls

Virtual reality -based post-stroke hand rehabilitation

A VR-based system using a CyberGlove and a Rutgers Master II-ND haptic glove was used to rehabilitate four post-stroke patients in the chronic phase. Each patient had to perform a variety of VR exercises to reduce impairments in their finger range of motion, speed

Virtual reality in neurorehabilitation
free download

Imagine the following scenario. Stuck in traffic, you have your digital agent make contact with the secretary at the Rehabilitation Center via your wireless palmtop. You are immediately provided with a verbal listing of your daily schedule. It is clear that you will have a tight

On temporal-spatial realism in the virtual reality environment
free download

Abstract The Polhemus Isotrak is often used as an orientation and position tracking device in virtual reality environments. When it is used to dynamically determine the users viewpoint and line of sight eg in the case of a head mounted display the noise and delay in its

The effects of virtual reality on consumer learning: an empirical investigation
free download

As competition in business-to-consumer e-commerce becomes fiercer, Web-based stores are attempting to attract consumers attention by exploiting state-of-the-art technologies. Virtual reality (VR) on the Internet has been gaining prominence recently because it enables

The virtual reality modeling language and Java

This paper describes a series of studies involving a haptic device which can display virtual textures and 3-D objects. The device has potential for simulating real world objects and assisting in the navigation of virtual environments. Three experiments investigated:(a)

Decoupled simulation in virtual reality with the MR toolkit
free download

Abstract The Virtual Reality (VR) user interface style allows natural hand and body motions to manipulate virtual objects in 3D environments using one or more 3D input devices. This style is best suited to application areas where traditional two-dimensional styles fall short

Disneys Aladdin: first steps toward storytelling in virtual reality

Virtual Reality (VR) is a new technology consisting on a graphic environment in which the user, not only has the feeling of being physically present in a virtual world, but he/she can interact with it. The first VR workstations were designed for big companies in order to create

Keynote address: haptics feedback for virtual reality
free download

Haptic feedback is a crucial sensorial modality in virtual reality interactions. Haptics means both force feedback (simulating object hardness, weight, and inertia) and tactile feedback (simulating surface contact geometry, smoothness, slippage, and temperature). Providing
