Abstract (eng)
The topic of this diploma thesis is augmented reality (AR) and smartphones. AR is a variation of virtual reality (VR), enabling us to overlay the real environment with virtual information and objects, and therefore enrich or extend the user’s perception. By definition, AR can be applied to all human senses. In this paper the main focus is exclusively directed towards visual perception, which can be visualized by means of displays.
The thesis is divided into two parts. The first one deals with the several components of AR such as displays, tracking techniques and registration, as well as interaction techniques that are needed for an AR system. Finally, the different fields of application of AR are examined and a classification of AR systems into indoor and outdoor systems is carried out.
The second part of the diploma thesis analyzes the question, how AR can be made accessible to a broader public. Here the emphasis is on mobile devices, so called handheld devices. Due to the rapid development and the massive distribution of smartphones, these "all-rounders" offer a perfect platform for the commercial implementation of AR applications. Different sensors such as a gps-receiver, a digital compass, accelerometers etc., which are standard features for each and every smartphone nowadays, are the required technical preconditions. Furthermore, the interaction of individual sensors is examined. Beside that, also concrete commercial AR applications on smartphones are described in a further chapter of the thesis. Hereby the research focuses on the so called AR browsers and the respective three main browsers are presented. Additionally, the strengths and weaknesses of AR browsers are discussed, and finally, we reveal a brief foreshadowing of the future perspectives of AR applications on smartphones.
