A starting point for discussion on use of augmented reality - here discussion will be held on topics such as simple AR for advancing product visualization in advertising, AR and heads up devices (HUDs) used for computer enhanced learning experiences, and AR for placing knowledge based information tags attached to objects.
Augmented reality involves a mixture of use of computer generated imagery and graphics with imaging of real world environment and vice versa. Simply put, it can be the use of computer enhanced imaging and it can be observed in a number of different applications commonly found in daily activities. It can be used in applications from architecture, to gaming, to personal entertainment and education and many different areas in between. Two common examples that can be used for reference are, the lines of scrimmage (otherwise known as the first down line) superimposed on the football field and which represent where the ball was hiked, and the radar and weather report that the weather broadcaster uses to describe the weather patterns on a screen background. Both of which are computer generated image enhancements that seem seamless to the viewer. In more complex examples, 3D images of objects can appear to be projected into the scene of a real world setting as though it is observed through the view of the camera.
Introducing Augmented Reality (AR)
The basic idea of augmented reality (AR) is to mix reality with virtual reality. Typically it is based on computer generated imagery overlaid or superimposed over real world views to create an augmented display. This display is then in turn returned back to the viewer for a seamless view that provides an illusion that the computer generated imagery is truly in the real world scene. The computer graphics that are generated for augmenting the real world scene can vary from 3D modeled objects, to video graphics and simple lines and text which can provide additional information about the augmented scene. Therefore, as suggested by Yu et al., AR can be a useful visualization technique that can be used for many domains such as engineering, medical, robot, military, mobile travel, education, entertainment and so on.

Of particular interest to those in the field of Engineering Technology are the uses of Augmented Reality as applied to use in Engineering Design. In the field of Design Drafting, for example much of the future success lays in the methods utilized for design. Various adaptations of emerging media technologies such as Augmented reality will be necessary for the sustainment of good design for the future. Computer science and the application of new technologies (including augmented reality) within higher educational institutions are a key topic of discussion among educational leaders across the nation. What institutions are providing towards computer aided design drafting (CADD) and technical illustration within their engineering technology curriculum is of particular concern for the engineer of 2020 and beyond.
Augmented Reality in Engineering Technology
Drafting is considered the visual language of industry and engineering. The technical drawing extension is the art and discipline of composing plans that virtually communicate how something functions or has to be constructed. Further extension to that is technical illustration, which is a specialized technique used to visually communicate information of a technical nature. These can be images that convey certain information such that the object "is" or "does". A prime example of these specialized and advanced methods of technical illustration is the use of augmented reality. A potential benefit is the use of augmented reality to facilitate visualization.
Imagine a group of product designers and engineers working together on a prototype model for a new client. Then during product development the group wanted to do a joint design review with the client, even though the client was not available for a face-to-face meeting. A remote meeting would be required and suddenly it was found desirable to present the design of the prototype mocked-up and imaged as a 3D object. The example below shows use of augmented reality to facilitate visualization of such a 3D object.

Even though the group and client are physically separated, if each of them had access to 3D CAD files, a model of the product can be enhanced with augmented reality and like the Viking Footwear example an interactive display of the product could be accomplished, where clients can simulate a walk around of the display looking at different aspects of it.
Another example of augmented reality use is to simulate projected media onto an object. By projecting media as information it can be used to assist the participant. The example below shows a mechanic wearing a tracked head-worn display which is used to demonstrate use of augmented reality for maintenance and repair (ARMAR) at Columbia University Computer Graphics and User Interface Lab. This example integrates real-world knowledge bases with detailed 3D models providing a system that can be used as a maintenance simulator and training tool. It also includes use of motion tracking, mobile computing, wireless networking, 3D Modeling, and human-machine interface technologies.

Many other forms and uses of augmented reality can be applied to engineering design and technology as well. Further examples are shown however this is just a small sampling of various forms of use. I would encourage you to explore these and many others as well.
