What is Virtual Reality?

Virtual reality is an artificial environment that is created with special software and presented to the user in such a way that the user is able to recognize himself and operate in that environment. Virtual reality has been widely used for gaming and general entertainment purposes, but the technology has also found its way into the military and medical fields.

Virtual reality systems have advanced significantly over the past decade. Virtual reality technologies hold great opportunities for the development of effective assessment techniques for neglect because they can provide “multimodal and highly controllable environments”. In a virtual world, the patient not only reacts to the stimuli, as occurs in the computerized tests, but can actually interact with this computer generated 3D, lifelike environment, providing an entire new realm of possibility for evaluation and treatment.

Virtual Reality in the past

One of the first attempts to use virtual reality in the treatment of USN was a non-immersive virtual environment for training safe street crossing in neglect patients. Some researchers have patients manipulate virtual objects with a haptic pen. Others use a head-mounted display to manipulate the patient’s view of the standard paper-and-pencil tests or track a moving ball.

Kinect, new approach to Virtual Reality

One of the newest (reasonably priced) Virtual Reality approaches is Microsoft Kinect. Kinect allows your console or PC to track your movements in real time. It’s ridiculously complicated and made up of tech that's been around for about 15 years, but allows for effects and functions that have only been available at huge expense up until very recently. Kinect enables also advanced gesture recognition, facial recognition, voice recognition, is capable of simultaneously tracking up to six people, including two active players for motion analysis.
