What is augmented reality?

Augmented reality is defined as a form of technology where computer generated images is superimposed onto objects as a form of enhancement. They improve or augment what is already there.

The integration of the real with the simulated blurs the boundary between the two as well as enhancing our senses. Augmented reality is nearer to the real world than virtual reality which is based upon fully immersive artificial worlds.

What does augmented reality use to generate this enhancement? It uses a variety of media such as graphics, video, smell and touch to mimic those found in the real world. It also changes the way we view the world.

Is this a good or bad thing? The concept of enhancing the world around us is not new as graphics have been superimposed over real world objects for some time now, e.g. television.

But augmented reality has expanded beyond that to include mobile phones, video/computer games and military applications. Mobile phones especially the iPhone use augmented reality apps which allow you to view computer generated images that have been superimposed over real world images. An example of this is an app which helps you to find a restaurant: it does this by displaying restaurant signs/logos as you move in a particular direction.

Another useful type of app is a golf GPRS system which helps golfers around a course. It displays yardages for each of the 18 holes, shows where the hazards are, e.g. bunkers and advice and support on improving your game. If you are golfer then this app will appeal to you immensely – look for the Golfscape Augmented Reality Rangefinder from the Apple store.

Augmented reality is also used in marketing and advertising as a means of enhancing certain aspects of a product in order to make it more attractive which will boost sales. This is discussed in more detail in our augmented reality marketing article.
