Features of Virtual Reality Systems
by Vahé Karamian
There are many different types of virtual reality systems but they all share the same characteristics such as the ability to allow the person to view three-dimensional images. These images appear life-sized to the person.
Plus they change as the person moves around their environment which corresponds with the change in their field of vision. The aim is for a seamless join between the person’s head and eye movements and the appropriate response, e.g. change in perception. This ensures that the virtual environment is both realistic and enjoyable.
A virtual environment should provide the appropriate responses – in real time- as the person explores their surroundings. The problems arise when there is a delay between the person’s actions and system response or latency which then disrupts their experience. The person becomes aware that they are in an artificial environment and adjusts their behaviour accordingly which results in a stilted, mechanical form of interaction.
The aim is for a natural, free-flowing form of interaction which will result in a memorable experience.

Although we talk about a few historical early forms of virtual reality elsewhere on the site, today virtual reality is usually implemented using computer technology. There are a range of systems that are used for this purpose, such as headsets, omni-directional treadmills and special gloves. These are used to actually stimulate our senses together in order to create the illusion of reality.

Virtual worlds are three dimensional environments in which you can interact with others and create objects as part of that interaction. How do you do that? You appear as an avatar in the virtual world: an avatar is a virtual representation of you (a 'virtual ego') which can take on any shape or form as you so wish.
