A Configurable Footswitch Unit for the Open Networked Neurosurgical OR – Development, Evaluation and Future Perspectives Dell’Anna, Jasmin; Janß, Armin; Clusmann, Hans; Radermacher, Klaus Ziegler, Jürgen Footswitches are used in the neurosurgical operating room for human-device-communication every day. However, problems, such as shifting or confusion of footswitches, often occur due to the parallel usage of up to 5 device-specific footswitches, resulting in a significant burden for the surgeon. There are no footswitches available which offer an optional central activation of different devices from various manufacturers and a reconfiguration during usage. Therefore, a new concept of a configurable central footswitch unit has been developed for optional activation of different devices in an open networked neurosurgical OR setting. In a user-centered evaluation 9 surgeons used both, the configurable central footswitch unit and 4 device-specific footswitches, for a cross-over experiment in an experimental OR setting. It shows that all surgeons were able to handle the configurable footswitch autonomously and that efficiency in surgeon-device-communication can be increased.

Introduction to this Special Issue on “Human-Machine Interaction and Cooperation in Safety-Critical Systems” Mentler, Tilo; Reuter, Christian; Geisler, Stefan Ziegler, Jürgen Mission- and safety-critical domains are more and more characterized by interactive and multimedia systems varying from large-scale technologies (e. g. airplanes) to wearable devices (e. g. smartglasses) operated by professional staff or volunteering laypeople. While technical availability, reliability and security of computer-based systems are of utmost importance, outcomes and performances increasingly depend on sufficient human-machine interaction or even cooperation to a large extent. While this i-com Special Issue on “Human-Machine Interaction and Cooperation in Safety-Critical Systems” presents recent research results from specific application domains like aviation, automotive, crisis management and healthcare, this introductory paper outlines the diversity of users, technologies and interaction or cooperation models involved.

Big Data in a Crisis? Creating Social Media Datasets for Crisis Management Research Reuter, Christian; Ludwig, Thomas; Kotthaus, Christoph; Kaufhold, Marc-André; Radziewski, Elmar von; Pipek, Volkmar Ziegler, Jürgen A growing body of research in the area of information systems for crisis management is based on data from social media. After almost every larger disaster studies emerge with the focus on the specific use of social media. Much of this research is based on Twitter data, due to the ease of access of this (mainly public) data, compared to (more closed) data, such as Facebook or Google+. Based on the experience gained from a research project on social media in emergencies and our task to collect social media data sets for other partners, we present the design and evaluation of a graphical user interface that supports those stakeholders (such as emergency services or researchers) that are interested in creating social media datasets for further crisis management research. We do not specifically focus on the analysis of social media data. Rather we aim to support the gathering process and how actors without sophisticated technical skills can be supported to get what they want and especially need: relevant social media data. Within this article, we present a practice-oriented approach and implications for designing tools that support the collection of social media data as well as future work.

Safety-Critical Personality Aspects in Human-Machine Teams of Aviation Eschen, Solveig C. S.; Keye-Ehing, Doris; Gayraud, Katja Ziegler, Jürgen Working safely and successfully in highly automated human-machine interfaces of future aviation is not only a matter of performance, but also of personality. This study examines which personality aspects correlate with safety-critical performance in human-machine teams. The research tools HTQ (Hybrid Team Questionnaire) and HINT (Hybrid Interaction Scenario) were combined for a comprehensive exploratory study. The HTQ includes personality scales measuring broad factors of personality (Big Five) as well as more specific scales and was added with objective personality assessments to measure risk taking. The simulation tool HINT simulates relevant processes in future human-machine team interaction in aviation. In a study with 156 applicants for aviation careers, safety-critical relations of some facets of general personality as well as risk taking were found. Especially personality aspects concerning disinhibiting, spontaneous behaviour and sensation seeking show correlations with poorer performance in the HINT simulation.
