ABSTRACT
Technology has changed the way people interact with the world. It has brought people closer together but also further apart. Technological change and advancement have been exponential since time began, gathering speed in the eighteenth-century “Age of Enlightenment” and accelerating since the middle of the twentieth century. Virtual reality is defined as “computer-generated simulation of a three-dimensional image or environment that can be interacted with in a seemingly real or physical way by a person using special electronic equipment, such as a helmet with a screen inside or gloves fitted with sensors”. Augmented reality has similarities with virtual reality, in that it uses computer-generated images, animations and sound, but instead of being a separate virtual world the images are overlaid with reality. Technology is generally expensive, and this is because of the high costs of development, and the high costs of ongoing maintenance and training.
