abstract = {Technology is indispensable in acute care and is seen primarily as a tool. However, 

media equation research shows that people also respond socially and naturally to machines 

as if they were other people. Using qualitative data from participant observations (130 hours) and retrospective interviews (N = 9), we show that technology in acute 

care settings also elicits reactions as one would typically exhibit towards other 

people. Based on existing media equation research, we address four aspects: source 

orientation, specialization, and the computers-are-social-actors hypothesis. Finally, 

we draw conclusions for qualitative data collection, design, and evaluation of technology 

in acute care, and discuss how to support human-machine teamwork.Technik ist in der 

Akutmedizin unverzichtbar und wird vor allem als Werkzeug gesehen. Die Forschung zur 

Media Equation zeigt jedoch, dass Menschen auch sozial und natürlich auf Maschinen 

reagieren, so als wären es andere Menschen. Wir zeigen anhand qualitativer Daten aus teilnehmenden Beobachtungen (130 Stunden) und retrospektiven Interviews (N = 9), dass 

Technik in der Akutmedizin ebenfalls Reaktionen auslöst, wie man sie üblicherweise 

gegenüber Mitmenschen zeigt. Dabei adressieren wir vier Aspekte der Media Equation 

Forschung: Negativität, Quellenorientierung, Spezialisierung und die Computers-Are-Social-Actors-Hypothese. 

Abschließend ziehen wir Schlussfolgerungen für qualitative Datenerhebungen, Design 

und Evaluation von Technik in der Akutmedizin, und diskutieren, wie die Zusammenarbeit 

von Mensch und Maschine im Team unterstützt werden kann.},

abstract = {In a typical home or office setting, a work desk provides a surface that primarily holds objects and is used for everyday tasks such as writing and typing. However, given its centrality and multiple surfaces, many of which are always unoccupied, an ordinary table may find secondary usage as an alternative interface to control facets of a smart home. For tabletop surfaces to work efficiently as alternative interfaces, there is a need to determine their most reachable zones and those that do not have too much clutter. We present Sweet Spots, an AR platform to visualize easily accessible and non-cluttered areas on table-like surfaces using augmented reality to assess suitable interaction areas. Sweet Spots provides designers and researchers with a tool to visualize their ideas and to take the exploration of key parameters that make an interaction area a Sweet Spot.},

abstract = {The need for remote usability testing has increased during the ongoing COVID-19 global pandemic. However, lockdown and physical distancing regulations have affected how HCI researchers conduct in-person tests of systems and technologies under design. We present a Pop-Up Observation Kit, which serves as an affordable mobile usability lab. The kit is sent to participants of a study alongside the system they are testing. The Pop-Up Observation Kit provides a simple, unobtrusive form factor that enables the study participant to concentrate on the task itself and not on documenting the task they are performing. While initially developed to observe hand and finger gestures on a pressure sensor mat for the Rich Interactive Materials for everyday objects project, the Pop-up Observation Kit also applies to other use cases. Additionally, the kit is extensible with additional functionalities combined with the sensor mat to enable better data collection or unmoderated remote observations.},

abstract = {Human-Computer Interaction (HCI) research has been focussing on the design of new interaction techniques and the understanding of people and the way they interact with computing devices and new technologies. The ways in which the work is performed with these interactive technologies has arguably been less of a focus. This workshop aims at addressing this specific aspect of Human-Computer Interaction in the control rooms domain. Control rooms are crucial elements of safety-critical infrastructures (e.g., crisis management, emergency medical services, fire services, power supply, or traffic management). They have been studied in terms of Human-Computer Interaction with respect to routine and emergency operations, human-machine task allocation, interaction design and evaluation approaches for more than 30 years. However, they are dynamic and evolving environments with, for instance, the gradual introduction of higher levels of automation/autonomy. While state of the art control rooms are still characterized by stationary workstations with several smaller screens and large wall-mounted displays, introducing mobile and wearable devices as well as IoT solutions could enable more flexible and cooperative ways of working. The workshop aims at understanding how recent technologies in HCI could change the way control rooms are designed, engineered and operated. This workshop is organized by the IFIP WG 13.5 on Human Error, Resilience, Reliability and Safety in System Development.},

abstract = {Control rooms represent critical infrastructures important for security and well-being of humans. While they have changed considerably with respect to information technologies within the last 30 years, user interfaces are, as our studies revealed, still characterized by windows, icons, menus, and pointers (WIMP). Further research on novel interaction design concepts for multi-monitor WIMP applications is necessary in addition to smart control room and pervasive computing environments approaches. In this study, we examined how control room operators can be supported in their daily work with multi- monitor applications. Based on human-centred design activities, the gaze-supported mouse interaction design concept ``Look & Drop'', approaching the most common interaction problems, e.g. moving the mouse pointer to distant screens, was developed. Results of a laboratory study, expert reviews and a proof of concept installation at a previously unknown control room indicate that Look & Drop could support operators at state-of-the-art control room workstations.},
