The present work is based on the research and design of a mobile AR experiment performed in the context of the emerging interdisciplinary fields of digital heritage and experience design. In an attempt to find a method to support the justification and discovery of elements that can influence the user towards the fulfilment of an objective in a heritage experience, my experimental research reveals that a combination of play moments including elements of embodiment and sensuousness in mobile AR are most suitable to convey a story. Determining suitable gameplay and game mechanics requires an appropriate setting and context for a user’s encounter with digital heritage. My research outlines a design methodology to reveal how the aesthetics of mobile AR technology can be designed to support critical user experiences through play and discovery. / Designing Digital Heritage.

Purpose – We propose a multidisciplinary approach based on an extensive data base which provides digitalized photographic material from the end of the 19th century up to recent times. Thus a large amount of photographic evidence will be exploited, structured and enriched by additional sources to serve as a foundation for an application relying on 3D visualizations. The application addresses scholars as well as the general public and will provide different kinds of information and tools for research and knowledge transfer. Design/methodology/approach – The method applied will be diachronic: the virtual model may show one point in urban history depicting a certain state of past Dresden and also its development through the various eras. In addition the method works in a dualistic mode: on the one hand the physical development of the urban area will be explored and presented in detail, on the other hand the analysis of the pictures will give profound insights in the specific perception of the urban space. Originality/value – This methodology aims to make large repositories more accessible and proactive in information-seeking. Using a 3D application as an access for media repositories, research tools and functionalities which can improve the scientific handling of the data will be considered. How should the data and information be processed to meet the researcher’s needs? Which information can be retrieved from the visual media? What needs to be considered to ensure scientific standards and motivation while working with the image repositories? Users of the virtual archives can benefit extensively form effective searching functions and tools which work not only content- and theme-based but also location-based. Practical implications – The outcomes of the research will be presented in a 4D browser and available in an Augmented Reality presentation. The design will comply with the requirements of the field of application, whether aiming at a scientific, educative or touristic purpose. The paper itself considers three different approaches to the topic highlighting the multidisciplinary strategy and opportunities of the project. The first one considers research questions from art history. The second one reflects on concepts from information science, photogrammetry and computer vision for visualizations and the third one introduces an interaction concept for an AR application for the Zwinger in Dresden.

Despite the rapidly growing adoption of augmented reality (AR) applications, existing methods for interacting with AR content are rated poorly, with surveyors of the area calling for better means of interaction, while researchers strive to create more natural input methods, mainly focusing on gesture input. This thesis aims to contribute to the aforementioned efforts by recognizing that technologies for consumer-grade smartphone-based pose estimation have been rapidly improving in recent years and due to their increased accuracy may have untapped potential ready to be utilized for user input. To this end, a rudimentary system for pose based input is integrated into prototype applications, which are constructed with both pose based input and touch input in mind. In this work, pose, pose estimation, and posed based input refer to using the distance and orientation of the user (or more precisely, the distance and orientation of their device) in relation to the AR content. Using said prototypes within a user interaction study allowed the identification of user preferences which indicate the approaches that future efforts into utilizing pose for input in an AR context ought to adopt. By comparing questionnaire answers and logged positional data across four prototype scenarios, it can be clearly identified that to perceive pose input as intuitive, the AR experiences shouldn’t employ a scale which is so large that it requires substantial shifts in the position of the user, as opposed to merely shifts in the position of the user’s device.

In this paper, a technical overview will be provided for a developed mobile exergame, with a particular focus on its movement tracking. By utilizing spatial movement readout from the AR algorithm, we've managed to create an easy to use exergame that allows the user to track their horizontal movement. In contrast to a more conventional approach, our solution can work indoors, and can be applied to vertical motion tracking as well. The applied method led to an exergame tailor-made for its target group, but it didn't include a thorough examination of other alternatives to our AR usage. This means that our solution should be researched further to better understand its relevance in the field, while we've shown with a practical example how it can be utilized. / Heart-eXg
