Following on from the triumph of the touchscreen, we see before us the advent of a new revolutionary technology which can change the interface between the real and the virtual world from the ground up.

Tim Cook, CEO of Apple, has the following Deutsche Bank Research is estimating to say on the subject: “It will happen in at approx. € 7.5 billion in 2020 (Deutsche a big way, and we will wonder when it Bank Research, 2015). does, kind of how we wonder how we live without our phone today” (Leswing, Augmented Reality versus 2016) Tim Cook expanded upon the “big Virtual Reality way” in which it could affect our lives: “I In order to take a detailed look at the do think that a significant portion of the subject matter, you first have to understand population [...], will have AR experiences what the concept of augmented reality every day, almost like eating three meals actually entails.

Even if most people haven´t yet consciously come into contact with the technology, numerous examples of augmented reality already exist in practice.

Seeing as reality in the most varied of situations. However, there are still a few areas augmented reality should present the real world as if one were looking through a that need addressing so as to enable a comprehensive application of the new standard pair of glasses, the relatively well-developed smartphone displays which are technology in the future. The following explains in more detail the three greatest now on offer are not entirely suitable as hardware. The added value of the data glasses challenges with regard to the hardware, software and user acceptance. lies in separately addressing both eyes, thereby enabling a spatial representation of the virtual content. Furthermore, the Making the hardware smart user has both hands free, and can use HoloLens AR glasses from Microsoft. It is when it comes to the hardware that However, even these AR glasses are the data glasses while working. These augmented reality poses great challenges in need of some improvement, which are crucial reasons why future-oriented to the manufacturer. As indicated at the is why they have only been used as an data glasses will win out for augmented start when we were generally considering example from the technical perspective reality applications (outside of the end the possible augmented reality hardware, for the general challenges in the area of customer area) against smartphones the development of Microsoft´s HoloLens hardware. and tablets.

As the many use cases show, augmented reality is therefore no longer just a trend of the remote future. Already today, we are seeing many examples in industry as well as in the everyday lives of each and every one of us.

Starting with marketing campaigns at Potentials for the workshop Opel, through to apps from Audi or MINI, in the automotive aftersales it is often possible users to integrate Augmented reality applications can make augmented reality in their everyday lives workshops much more efficient overall. without any special additional equipment. They can shorten workshop times and The industry has also recognised the the associated waiting times for the very promising potential in the use of customer, in turn increasing customer this innovative technology in production satisfaction. This area has often been processes, and has already successfully characterised by employees having to tested it in pilot projects, for example as put in a lot of leg work to fulfil their duties, shown by Volkswagen with its use in the which has caused valuable time to be lost. plant logistics. Added to this is the increased complexity and model variety of the vehicles, as Alongside the increase in efficiency in the well as the growing use of special tools production, there are also considerable and automotive fluids for repair work. opportunities to be exploited in the Researching suitable repair manuals is automotive industry as well as particularly tedious, time-consuming and requires in aftersales.

The automotive industry is currently experiencing a radical change, and must continue to strive forward so as to be able to integrate augmented reality into the already functioning processes. Available potentials can be exploited here, particularly in the workshop environment.
