Virtual Reality

What is Virtual Reality?

Virtual reality or virtual realities (VR), also known as immersive multimedia or computer-simulated reality. It is a computer technology that replicates an environment, real or imagined, and simulates a user’s physical presence and environment in a way that allows the user to interact with it. Virtual realities artificially create sensory experience, which can include sight, touch and hearing.

Features of virtual reality systems

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 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.
