- WorkshopbeitragThe AR-Marker in the Urban Space(Mensch und Computer 2019 - Workshopband, 2019) Nestler, Simon; Pranz, Sebastian; Neuburg, KlausWhen considering the role of Augmented Reality (AR) in the urban space, most previous work is focusing on touristic and everyday life use cases. However, the project “Archäologie der Gegenwart” which we present in this paper illustrates the different aspects of change in Hamm during the last 50 years. Thus, our AR approach opens up a deeper understanding of the urban cultural change processes by the means of AR. Our considerations lead to adding an AR layer as a fifth social dimension in the urban space. Technically, we robustly link this fifth layer with the existing topography by marker-based tracking with six degrees of freedom (6 DOF). When building AR applications for the urban space, the deeper understanding of the marker paradigm is crucial: During our workshops we identified and analyzed seven requirements for the utilization of markers in the public urban space. Additionally, we analyzed the general AR marker paradigm from the human-computer interaction (HCI) perspective by considering the affordances and signifiers of the marker objects themselves, analyzing the tracking technology and summarizing the marker’s role for past, present and future AR applications. Thus, the role of the AR marker is twofold: On the one hand the marker is part of the 6 DOF tracking technology, on the other hand it makes AR layers perceivable in the urban space. We expect that the importance of these markings for guiding citizens through AR experiences will emerge in urban spaces, whereas the role of markers for technical tracking purposes will decrease.
- WorkshopbeitragIntuitive Interfaces? Interface Design and its Impact on Human-Robot Interaction(Mensch und Computer 2019 - Workshopband, 2019) Muhle, Florian; Bock, IndraOne goal of developing humanoid robots and virtual agents is to allow for intuitive and natural interaction with technical systems. However, up to now existing robotic systems do not live up to this promise. Based on an empirical approach that combines the analysis of the interface design of three different robot/agent systems with the micro-analysis of empirical encounters between humans and respective systems, we show that and how the systems provide contradictory 'affordances', which make it systematically difficult to start and continue satisfying interactions with them.
