Augmented Reality

world information computer user

Definition: Augmented reality is a system that enhances the real world by superimposing computer-generated information on top of it.

Virtual Reality (VR) is the technology that provides almost real and/or believable experiences in a synthetic or virtual way. Augmented Reality (AR) can be thought of as a variation of VR. In the original publication which coined the term, (Computer-) Augmented Reality was introduced as the opposite of VR: instead of driving the user into a purely-synthesized informational environment, the goal of AR is to augment the real world with synthetic information such as visualizations and audio. In other words, AR is a system that enhances the real world by superimposing computer-generated information on top of it. VR technologies completely immerse a user inside a synthetic environment. While immersed, the user can not see the real world around him/her. In contrast, AR allows the user to see the real world, but superimposes computer-generated information upon or composed with the real world. Therefore, AR supplements reality, rather than completely replacing it. Combining 3D graphics with the real world in a 3D space is useful in that it enhances a user’s perception of and interaction with the real world. In addition, the augmented information, such as annotations, speech instructions, images, videos, and 3D models, helps the user perform real world tasks. Figure 1 shows a wearable computer used for the implementation of AR of an industry training application.
