abstract = {State-of-the-art control rooms are equipped with a variety of input and output devices in terms of single-user workstations, shared public screens, and multimodal alarm systems. However, operators are bound to and sitting at their respective workstations for the most part of their shifts. Therefore, cooperation efforts are hampered, and physical activity is limited for several hours. Incorporating mobile devices, wearables and sensor technologies could improve on the current mode of operation but must be considered a paradigm shift from control rooms as a collection of technically networked but stationary workstations to control rooms as pervasive computing environments being aware of people and processes. However, based on the reviewed literature, systematic approaches to this paradigm shift taking usability and user experience into account are rare. In this work, we describe a root concept for control rooms as human-centered pervasive computing environments and introduce a framework for developing a wearable assistant as one of the central and novel components. Furthermore, we describe design challenges from a socio-technical perspective based on 9 expert interviews important for further research on pervasive computing environments in safety-critical domains.},

abstract = {Control room operators rely on a range of technologies to communicate crucial information and dependably coordinate a disparate collection of tasks and procedures. Tools that are capable to design, to implement, and to evaluate interactive systems that can assist the tasks of control room operators in these environments therefore play an important role. This paper offers a framework that facilitates the early research steps into evaluating work flows, interfaces, and wearable sensors in the context of an emergency dispatch center. It entails a primarily web-based, quick-to-deploy, and scalable method that specifically targets preliminary studies in which large-scale and situated deployments are not feasible. By using open-source and affordable wrist-worn sensors, it furthermore enables investigating any relationships between interaction design in control rooms and operators' physiological data. Our evaluation on a preliminary study with 5 participants shows that basic scenarios are able to induce differences which can be measured by reaction times in the interactions as well as in the data from the smartwatch.},

abstract = {As immersive virtual experiences find their way into our living room entertainment, they are becoming part of our daily technological consumption. However, state-of-the-art virtual reality (VR) remains disconnected from other digital devices in our environment, such as smartphones or tablets. As context switches between acting in the virtual environment and resolving external notifications negatively influence immersion, we look towards integrating smart devices into virtual experiences. To this aim, we present the VRySmart framework. Through either optical marker tracking or simultaneous localization and mapping (SLAM), embedded smart devices can be used as VR controllers with different levels of integration while their content is incorporated into the virtual context to support the plausibility of the illusion. To investigate user impressions, we conducted a study (N = 10) where participants used a smartphone in four different virtual scenarios. Participants positively assessed smart device usage in VR. We conclude by framing implications for future work.},

abstract = {Existing virtual reality (VR) authentication schemes are either slow or prone to observation attacks. We propose CueVR, a cue-based authentication scheme that is resilient against observation attacks by design since vital cues are randomly generated and only visible to the user experiencing the VR environment. We investigate three different input modalities through an in-depth usability study (N= 20) and show that while authentication using CueVR is slower than the less secure baseline, it is faster than existing observation resilient cue-based schemes and VR schemes (4.151 s–7.025 s to enter a 4-digit PIN). Our results also indicate that using the controllers’ trackpad significantly outperforms input using mid-air gestures. We conclude by discussing how visual cues can enhance the security of VR authentication while maintaining high usability. Furthermore, we show how existing real-world authentication schemes combined with VR’s unique characteristics can advance future VR authentication procedures.},

Haptics cannot only increase the user experience and make technology more immersive, it can also transmit information that is hard to interpret only through vision and audio, such as the softness of a surface or other material properties. In this workshop, we aim at discussing how we could interact with technology if haptics is strongly supported and which novel research areas could emerge.},

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

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.

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.},
