Collaboration in Augmented Reality: How to establish coordination and joint attention?

Schnier C, Pitsch K, Dierker A, Hermann T. Collaboration in Augmented Reality: How to establish coordination and joint attention? In: Boedker S, Bouvin NO, Lutters W, Wulf V, Ciolfi L, eds. Proceedings of the 12th European Conference on Computer Supported Cooperative Work (ECSCW 2011). Springer-Verlag London; 2011: 405-416.We present an initial investigation from a semi-experimental setting, in which an HMD-based AR-system has been used for real-time collaboration in a task-oriented scenario (design of a museum exhibition). Analysis points out the specific conditions of interacting in an AR environment and focuses on one particular practical problem for the participants in coordinating their interaction: how to establish joint attention towards the same object or referent. Analysis allows insights into how the pair of users begins to familarize with the environment, the limitations and opportunities of the setting and how they establish new routines for e.g. solving the ʻjoint attentionʼ-problem

Exploring whole body interaction and design for museums

Museums increasingly use digital technology to enhance exhibition experiences for families, notably in relation to physically mediated installations for young children through natural user interfaces. Yet little is known about how families and children engage with such installations and the kinds of interactive experiences they engender in museum spaces. This paper addresses a pressing need for research to adopt an analytical focus on the body during such digitally mediated interactions in order to understand how bodily interaction contributes to meaning making in the museum context. It reports an observation study of families and children interacting with a whole-body interface (using Kinect) in the context of an installation in a museum exhibit on rare Chinese paintings. The study shows how the installation design engenders particular forms of bodily interaction, collaboration and meaning making. It also contributes design insights into whole-body interaction installations in museums and public spaces

Practical, appropriate, empirically-validated guidelines for designing educational games

There has recently been a great deal of interest in the potential of computer games to function as innovative educational tools. However, there is very little evidence of games fulfilling that potential. Indeed, the process of merging the disparate goals of education and games design appears problematic, and there are currently no practical guidelines for how to do so in a coherent manner. In this paper, we describe the successful, empirically validated teaching methods developed by behavioural psychologists and point out how they are uniquely suited to take advantage of the benefits that games offer to education. We conclude by proposing some practical steps for designing educational games, based on the techniques of Applied Behaviour Analysis. It is intended that this paper can both focus educational games designers on the features of games that are genuinely useful for education, and also introduce a successful form of teaching that this audience may not yet be familiar with

The Gaia System: A Tabletop Projection Mapping System for Raising Environmental Awareness in Islands and Coastal Areas

Islands and coastal areas, including those in the Nordic region, are considered highly vulnerable to the impacts of climate change. Raising environmental awareness is a crucial first step towards protecting the ecosystem and preventing environmental deterioration. In this work-in-progress paper, the first version of the Gaia System is presented, and its use for raising environmental awareness is described. The Gaia System is a tabletop projection mapping system installed at the Sortland Museum in the Vesterålen district, Norway. The system creates a digital twin of the area and enables the user to interact with and explore time (i.e. navigate to the past, the present and the future of the visualised area). The Gaia System targets residents, tourists and stakeholders of the Vesterålen district as its users, aiming to contribute to the sustainable development of the local community through establishing new behaviour patterns among users and/or being used in decision-making processes. The Gaia System prototype was informally evaluated during a demonstration event, when positive feedback was received. However, several adjustments and additions will be made in the next version.publishedVersio

Towards the 3D Web with Open Simulator

Continuing advances and reduced costs in computational power, graphics processors and network bandwidth have led to 3D immersive multi-user virtual worlds becoming increasingly accessible while offering an improved and engaging Quality of Experience. At the same time the functionality of the World Wide Web continues to expand alongside the computing infrastructure it runs on and pages can now routinely accommodate many forms of interactive multimedia components as standard features - streaming video for example. Inevitably there is an emerging expectation that the Web will expand further to incorporate immersive 3D environments. This is exciting because humans are well adapted to operating in 3D environments and it is challenging because existing software and skill sets are focused around competencies in 2D Web applications. Open Simulator (OpenSim) is a freely available open source tool-kit that empowers users to create and deploy their own 3D environments in the same way that anyone can create and deploy a Web site. Its characteristics can be seen as a set of references as to how the 3D Web could be instantiated. This paper describes experiments carried out with OpenSim to better understand network and system issues, and presents experience in using OpenSim to develop and deliver applications for education and cultural heritage. Evaluation is based upon observations of these applications in use and measurements of systems both in the lab and in the wild.Postprin

The Impact of Experiential Augmented Reality Applications on Fashion Purchase Intention

Utilizing the stimulus-organism-response (SOR) model, the purpose of this study is to examine the effects of augmented reality (AR) (specifically augmentation) on consumers’ affective and behavioral response and to assess whether consumers’ hedonic motivation for shopping moderates this relationship. An experiment using the manipulation of AR and no AR was conducted with 162 participants aged between 18 and 35. Participants were recruited through snowball sampling and randomly assigned to the control or stimulus group. The hypothesized associations were analyzed using linear regression with bootstrapping. The paper demonstrates the benefit of using an experiential AR retail application (app) to positively impact purchase intention. The results show this effect is mediated by positive affective response. Furthermore, hedonic shopping motivation moderates the relationship between augmentation and the positive affective response. Because of the chosen research approach, the results may lack generalizability to other forms of augmentation. Therefore, researchers are encouraged to test the proposed model using different types of AR stimuli. Furthermore, replication of the study with other populations would increase the generalizability of the findings. Results of this study provide a valuable reference for retailers of the benefits of using AR when attempting to optimize experiential value in online environments. The study contributes to experiential retail and consumer purchase behavior research by deepening the conceptualization of the impact of experiential technologies, more specifically AR apps, by considering the role of hedonic shopping motivations.Peer reviewe
