However, re-solutions to wicked problems embodied in frame and change the understanding of the problem itself. Research through Design (RtD) is a constructive methodology to understand this interplay of problem framing through designing artifacts. RtD is also suited to resurface the theory within those artifacts through annotation. These annotations expose and emphasize qualities, values and assumptions held within artifacts by its creators. In addition to those modes for annotation, we will suggest two additional abstract frames through which RtD artifacts can be further annotated: Open Research Agenda and Interdisciplinarity. We will apply both frames to one research artifact, Loaded Dice to distill qualities from this artifact’s framing. Through this we will show how creating and deploying an artifact can change its environment which also includes its creators. 2017-01-01T00:00:00Z http://dl.gi.de/handle/20.500.12116/6153 Designing a Holistic Behavior Change Support System for Healthy Aging Herrmanny, Katja; Schwarz, Michael; Paldán, Katrin; Beckmann, Nils; Sell, Jennifer; Wagner, Nils-Frederic; Dogangün, Aysegül Ziegler, Jürgen In this paper, we describe the development of a behavior change support system to improve health. The system is designed for people in the age range of 50–65 with an interdisciplinary approach. The basic structure of the presented system consists of two main modules: a monitoring module to collect and analyze data and an intervention module to support behavior changes. Based on the results of a requirements analysis and findings gathered from a conducted literature review and own analyses, the behavior change system addresses the following lifestyle areas: physical activity, nutrition, mental fitness, sleep, and nature contact. We outline how the concept is developed with regards to the results of the requirements analysis and psychological foundations to explain and predict motivation and behavior change processes. We describe how single system components match phases of behavior change models and how they were implemented into an Android application. Finally, we present the results of usability studies where the comprehensibility of the concept and application was tested together with the usability of navigation structure and design. The results show that the target group is able to understand the concept and can navigate through the system easily. 2017-01-01T00:00:00Z http://dl.gi.de/handle/20.500.12116/6155 On the Attempt to Implement Social Addressability within a Robotic System Graf, Philipp; Marquardt, Manuela; Compagna, Diego Ziegler, Jürgen We conducted a Human-Robot Interaction (HRI) study during a science event, using a mixed method experimental approach with quantitative and qualitative data (adapted version of Godspeed Questionnaire and audio-visual material analysed videographically). The main purpose of the research was to gather insight into the relevance of the so-called “point of interaction” for a successful and user-friendly interaction with a non-anthropomorphic robot. We elaborate on this concept with reference to sociological theories under the heading of “addressability” and “social address” and generate hypotheses informed by former research and theoretical reflections. We implement an interface on our robot system, comprising two LEDs, which indicate the status of the robot/interaction, and which might possibly serve as basal form of embodied social address. In one experimental condition, the movements were accompanied by a light choreography, the other one was conducted without the LEDs. Our findings suggest a potential relevance of social address for the interaction partner to receive additional information, especially if the situation is a contingent one. Nevertheless, the overall rating on the Godspeed scales showed no significant differences between the light conditions. Several possible reasons for this are discussed. Limitations and advantages are pointed out in the conclusion. 2017-01-01T00:00:00Z http://dl.gi.de/handle/20.500.12116/6156 S. Diefenbach/M.
