- KonferenzbeitragDesign Problem-Solving with External Representations(Workshop-Proceedings der Tagung Mensch & Computer 2009, 2009) Wiese, Eva; Adenauer, JulianTo develop a product out of a set of given variables and operators, complex information processing and the application of problem-solving strategies is needed. Unfortunately, these complex requirements on human problem-solving abilities are confronted with the designer’s cognitive and creative limitations resulting from a restricted working-memory capacity. To overcome these limitations and to foster a creative and innovative product development, suitable supporting systems are needed. Their development should be based on a profound understanding of the cognitive actions and perceptual processes that are involved in design problem-solving. Thereby, a permanent exchange between internal thinking, reasoning and decision making steps and external writing, sketching and verbalisation steps takes place. The most challenging question in this context is how external representations should be configured and how interaction with these representations should be implemented to efficiently combine mental and motor actions. Another interesting question is, whether virtual environments are helpful for design problem-solving by providing information-rich, interactive visualisations in a 3D manner. To answer these questions and to deduce cognitively based guidelines for the development of design support systems, several experiments in virtual environments are planned in a laboratory setting.
- KonferenzbeitragMixed reality mockups for multimodal evaluation of product prototypes(Workshop-Proceedings der Tagung Mensch & Computer 2009, 2009) Adenauer, Julian; Wiese, EvaIn the process of industrial product development, there is a constant need for prototypes representing the current state of development. Since the manufacturing of physical prototypes is very cost-intensive, virtual prototypes gain more and more importance. Moving from a 2.5D screen visualization to a 3D virtual reality visualization (e.g. in a CAVE) offers a better spatial impression and the possibility of visualizations in a 1:1 scale. However, those virtual prototypes cannot be a complete replacement for physical ones because of their exclusively visual nature which does not allow the evaluation of non-visual features like weight and inertia. We propose using mixed reality (MR) technologies to serve as a bridge between virtuality and reality, combining the advantages of both worlds. These functional and intuitively usable prototypes enable the designer to find flaws in the concept and allow the inclusion of customer-feedback and usability tests in early development phases.
- WorkshopbeitragTime and Timing in Human-Computer Interaction(Mensch und Computer 2023 - Workshopband, 2023) Riemer, Martin; Bogon, Johanna; Rußwinkel, Nele; Henze, Niels; Wiese, Eva; Halbhuber, David; Thomaschke, RolandTime perception is an integral aspect of human experience and has numerous implications for the communication between humans and computers. When interacting with computers, user experience is often compromised by non-optimal latency and temporal misperception. In this workshop, we gather scientists from diverse research fields (including Human-Computer Interaction, Psychology, Computer Sciences, and Design) to discuss the possibilities of altering the temporal experience of users of interactive systems and to reflect on the potential benefits and risks of such a systematic manipulation. This workshop aims to foster a shared understanding of imminent research questions at the intersection of time perception and HCI research and to identify strategies for tackling them in collaborative projects.
- WorkshopbeitragTime Matters - Even (more so) in Human-Robot Interactions(Mensch und Computer 2023 - Workshopband, 2023) Russwinkel, Nele; Wiese, EvaRobots are more and more integrated into everyday environments, which makes it essential to examine how to design them so that humans are motivated and capable to interact with them. An important challenge for robotics is to determine how to design robotsthat accurately infer the human interaction partner’s goals, intentions, and emotional states, and are able to adapt to their actions in time and space. Certain aspects of this challenge can be addressed through appropriate design of robot appearance and behavior, and equipping robots with appropriate models of social cognition. Other aspects, however, arise on the human side of the “equation”, where lifelong experience with human interaction partners raises certain expectations of how verbal and nonverbal social cues are supposed to be interpreted, how actions are supposed to be coordinated and how emotional and motivational states are supposed to be communicated. If a robot meets these expectations, humans can interact with it quite intuitively, make accurate predictions regarding its actions and intentions, and interpret its social signals with ease. The question is how robots can be equipped with representations to meet these expectations. Most robots, however, violate anthropomorphic expectations in terms of their appearance, behavior and cognition, which can negatively impact performance, affect and motivation in human-robot interaction. In this paper, we discuss how the interplay between robots’ actual capabilities and human expectations regarding these capabilities imposes challenges specifically for the time- dependent aspects of social human-robot interactions.
