These interfaces need to be reliable and robust regarding the environmental conditions to guarantee safety of the user and enable a direct interaction between a human and a machine. This paper presents a hybrid MARG and visual sensor system for head orientation estimation which is in this case used to teleoperate a robotic arm. The system contains a Magnetic Angular Rate Gravity (MARG)-sensor and a Tobii eye tracker 4C. A MARG sensor consists of tri-axis accelerometer, gyroscope as well as a magnetometer which enable a complete measurement of orientation relative to the direction of gravity and magnetic field of the earth.

Their purpose is to enable a computer-supported collaboration between multiple users that is based on a seamless use of different devices for natural “post-WIMP” interaction (e.g., multitouch walls, interactive tabletops, tablet PCs, or digital pen and paper). However, to this day, there are no well-established guidelines or toolkits for designing and implementing such distributed user interfaces (DUIs). Therefore, this article introduces the Zoomable Object-Oriented Information Landscape (ZOIL), a novel design approach and software framework for post-WIMP DUIs in interactive spaces. In the following, the ZOIL design principles are first introduced and illustrated. They provide recommendations and examples of DUI interaction design for interactive spaces. Then the different software patterns and architectures that have been employed for implementing the open-source ZOIL software framework are described. This framework facilitates the implementation of ZOIL's design principles in practice.

Their purpose is to enable a computer-supported collaboration between multiple users that is based on a seamless use of different devices for natural “post-WIMP” interaction (e.g., multitouch walls, interactive tabletops, tablet PCs, or digital pen and paper). However, to this day, there are no well-established guidelines or toolkits for designing and implementing such distributed user interfaces (DUIs). Therefore, this article introduces the Zoomable Object-Oriented Information Landscape (ZOIL), a novel design approach and software framework for post-WIMP DUIs in interactive spaces. In the following, the ZOIL design principles are first introduced and illustrated. They provide recommendations and examples of DUI interaction design for interactive spaces. Then the different software patterns and architectures that have been employed for implementing the open-source ZOIL software framework are described. This framework facilitates the implementation of ZOIL's design principles in practice. Lessons learned from ZOIL's implementation are shared, and the implementation is discussed and compared with related work and approaches. The results of an evaluation of ZOIL with designers and developers conclude the article. |

This is insofar surprising, as Longitudinal Research provides the exceptional advantage compared to cross-sectional research of being able to analyze change processes. Therefore, it incorporates time as a dependent variable into the research design by gathering data from multiple points in time. Change processes are not just an additional research area but are essential to our understanding of the world, with HCI being no exception. Only Longitudinal Research allows us to validate our assumptions over time. For example, a user experience study for an electronic consumer product, such as a TV-set, that reveals how excited people about the device are, should also investigate whether this excitement holds over time, whether usability issues arise after two weeks, and eventually whether people will buy the follow-up product form the same company. Our experience with technology is situated in context, and time is one important aspect of our context – ignoring does not necessarily lead to invalid but often insignificant research. In this thesis, we contribute to the area of Longitudinal Research in HCI in manifold ways. First, we present a taxonomy for Longitudinal Research, which provides a foundation for the development of the field. It may serve both as a basis for discussion and methodological advances as well as a guiding framework for novices who strive to apply Longitudinal Research methods. Second, we provide a practical contribution by presenting PocketBee, a multi-modal diary for longitudinal field research. The tool is based on Android smartphones and allows researchers to conduct remote longitudinal studies in a variety of ways. We embed the discussion of PocketBee in a broader discussion of the diary and experience sampling methods, allowing researchers to understand the context of the tool, the advantages and also the inherent problems. Eventually, we present the Concept Maps method, which tackles a specific is-sue of Longitudinal Research – the difficulty to analyze changes in qualitative data over time, as these are normally hidden in large amounts of data and sub-ject to the interpretation of the researcher. In the context of API usability, the method allows the externalization of the mental model developers generate. Concept Maps are used for these external representations and by continually updating these maps, changes over time become apparent and the analysis replicable. The thesis will also help researchers to discover further important research are-as in this field, as for example the variety of methodological issues that arise with gathering data over time. As the topic of Longitudinal Research has not yet been covered comprehensively in the scientific HCI literature, this thesis provides an important first step.}, keywords = {concept maps, diary, hci, longitudinal, pocketbee, taxonomy}, pubstate = {published}, tppubtype = {phdthesis} } The goal of this thesis is to shed more light into an area of empirical research, which has only drawn minor interest in the field of Human-Computer Interaction so far – Longitudinal Research.
