Fortmann, Jutta; Glanert, Frank In this article, we give insights into the development of an ‘interface of energy’, which is developed as part of the energy turnaround project ‘enera’. This interface shall allow communication between the human and the future energy network which will be dominated by renewable energy sources and on-site power generation. We show how we applied Human-Centered Design methods to address the challenge of designing a user interface for an infrastructure that is still in development. Further, we show how this approach was successfully combined with public relations, such as feedback sessions on prototypes as part of an open Barcamp. We give insights into interviews, profiles, personas, public operations, user needs, prototyping and testing. As a special feature we conducted prototyping and prototype testing workshops in a residential house within the project region. These turned out to be very successful for many reasons, e. g., in that the natural environment served as a creative stimulator. Besides, the workshops had a lasting effect on the participants, who were members of the project as well as volunteers living in the project region. 2019-01-01T00:00:00Z http://dl.gi.de/handle/20.500.12116/21839 Perception of an Uncertain Ethical Reasoning Robot Stellmach, Hanna; Lindner, Felix This study investigates the effect of uncertainty expressed by a robot facing a moral dilemma on humans’ moral judgment and impression formation. In two experiments, participants were shown a video of a robot explaining a moral dilemma and suggesting a decision to make. The robot either expressed certainty or uncertainty about the decision it suggests. Participants rated how much blame the robot deserves for its decision, the moral wrongness of the chosen action, and their impression of the robot in terms of four scale dimensions measuring social perception. The results suggest that the subpopulation of participants unfamiliar with the moral dilemma assigns significantly more blame to the uncertain robot as compared to the certain one, while expressed uncertainty has less effect on moral wrongness judgments. The second experiment suggests that higher blame ratings are mediated by the fact that the uncertain robot was perceived as more humanlike. We discuss implications of this result for the design of social robots. 2019-01-01T00:00:00Z http://dl.gi.de/handle/20.500.12116/21835 Self-Encounter in Virtual Reality in Robot-Based Telepresence von der Heyde, Markus Have you ever met yourself? Have you met your past? This report is meant to make a phenomenon known in which VR users at a break-in-presence do not fall back into the lab environment. However, we are not yet able to provide tangible evidence and systematic research about it. Setup: We describe a virtual reality application which originally was intended to provide control for a search and rescue robot. Due to a design requirement to use very limited resources, we developed a sparse representation of the past of the robot. The user encounters the past path of the robot in VR as a collection of 360° photo-spheres which each captures one instant. Multiple users of the application can individually review all past pictures. The most recent picture represents the current perspective of the robot. In addition, each user can interact with virtual objects, e. g., control the robot. Observation: According to perceptual research, breaks-in-presence might occur after sensory conflicts. An encounter of one’s self in VR introduces a perceptual and cognitive conflict. Users were able to realign with their own episodic memory and did not fall back into the lab environment as a result of this new type of break-in-presence. 2019-01-01T00:00:00Z http://dl.gi.de/handle/20.500.12116/21836 Argus Vision: A Tracking Tool for Exhibition Designers Skowronski, Moritz; Klinkhammer, Daniel; Reiterer, Harald Contemporary exhibitions are increasingly staged using extensive and often interactive media. To create such exhibitions, exhibition design companies employ professionals from a wide range of different disciplines. The support of interdisciplinary exhibition designers in the design process is one goal of research in Human-Computer Interaction. This includes the deployment of Do-It-Yourself (DIY) Tools that enable professionals from all disciplines involved to design and create interactive media themselves. In this paper, we will present Argus Vision, a DIY Tool, which allows exhibition designers the use of camera-tracking to rapidly prototype and develop immersive exhibitions and interactive installations. We successfully used Argus Vision in two real-world case studies both in the prototyping and in the deployment of two installations in exhibitions. Additionally, we conducted expert interviews with exhibition designers, investigating the tool’s usefulness for them. 2019-01-01T00:00:00Z
