Safety-critical HCI

I am researching on the application of HCI principles to safety-critical systems. I focus on people using interactive systems while being involved in mentally demanding tasks. During my previous research I designed and developed interactive systems for car drivers to support them ahead of critical situations. I developed mobile solutions for emergency teams to facilitate the triage processes during disasters. Furthermore, I developed collaborative multi-touch interfaces in order to prepare rescue teams for large scale crisis situations. I analysed the process of collaborative problem solving on multi-touch interfaces as well as on mobile devices. Additionally, I dealed with the usage of RFID devices for identifying and tracking patients in emergencies. I developed a heuristic for evaluating the usability of user-interfaces in lifethreating, time-critical and unstable situations. Moreover, I developed an concept for integrating information from social media in the crisis management processes. I developed mobile apps for guiding and supporting citizens during disasters. Last but not least, I developed a virtual reality system for evaluating interfaces for emergency situations.

Digital Topographies. Using AR to Represent Archival Material in Urban Space (2020)

In this paper we discuss how Augmented Reality as a form of spatial computing can contribute to the concept of a mediated city, and tackle possible problems that we understand as conflicts between different modes of spatial perception. In reference to Spatial Sociology we assume that space includes a physical dimension as well as a social dimension and discuss a multidimensional framework to analyze AR applications. We argue that spatial computing provides a digital topography that creates new ways of understanding and orientation as well as multidimensional problems. As an example we present an ...

The AR-Marker in the Urban Space: Affordances and Roles of AR Markers from an HCI Perspective (2019)

When considering the role of Augmented Reality (AR) in the urban space, most previous work is focusing on touristic and everyday life use cases. However, the project Archäologie der Gegenwart which we present in this paper illustrates the different aspects of change in Hamm during the last 50 years. Thus, our AR approach opens up a deeper understanding of the urban cultural change processes by the means of AR. Our considerations lead to adding an AR layer as a fifth social dimension in the urban space. Technically, we robustly link this fifth layer with the existing topography by marker-based ...

Social Emergency Software - die Zukunft des Behördenfunks? (2018)

Mithilfe des gegenwärtig zur Verfügung stehenden (digitalen) Behördenfunks lässt sich eine nahtlose Skalierung der Strukturen des Krisenmanagements in großen und komplexen Schadenslagen nur eingeschränkt realisieren. Denn die der Kommunikation zugrunde liegenden statischen Hierarchien und Strukturen lassen sich nicht flexibel und adaptiv an die Komplexität und Dynamik der Schadenslage adaptieren. Daher stellt sich die Frage, inwieweit in anderen Branchen etablierte Konzepte für eine neue Art der digitalen Kommunikation auch die Kommunikation zwischen Einsatzkräften ...

Virtual Reality Crisis Simulation for Usability Testing of Mobile Apps (2015)

Usability testing is expensive in some fields due to the resource requirements that go hand in hand with taking the context of use into account. Crisis related applications are one such field, typically requiring the reenactment of an extensive crisis scenario. To lessen the resource requirements crisis scenarios can be reconstructed as virtual reality simulations. This paper outlines the development of an initial prototype of such a simulation. A refined prototype could eventually allow usability testing of a mobile app in a virtual reality crisis simulation.

Evaluating human-computer-interaction in crisis scenarios (2014)

The various processes in crisis management are uncertain, unstable and time-critical. In crisis scenarios the support of emergency workers by the means of interactive systems is challenging. Even smaller blind spots in the human-computer- interaction (HCI) might cause the unusability of the overall crisis management system. Therefore, regular usability testing of the overall system by emergency workers is essential in crisis scenarios. In crisis management usability tests are the foun- dation for the successful introduction of interactive systems. Usability tests in crisis situations are highly ...

Creating a common operation picture in realtime with user-centered interfaces for mass casualty incidents (2012)

Accurate, accessible, and realtime information on the number, location, and medical condition of patients are critical for the successful management of mass casualty incidents (MCIs), where the number of patients exceeds the capacity of the emergency management service (EMS). We present a concept of a collaborative infrastructure which generates a common operation picture in realtime. A complex, stressful and uncommon situation like an MCI creates strong psychological influences and burdens on the rescue workers. Based on our psychological findings we derived eleven special requirements for efficient ...

RFID based Patient Registration in Mass Casualty Incidents (2011)

In MCIs (mass casualty incidents) the EMC (emergency medical chief) has to gain an overview on all patients at the scene. When using paper based patient tags the patient-related information remains at the patients themselves and the information relay is complex. We propose a RFID based solution, which makes the local patientrelated information available to all relief workers at the scene. As a consequence all processes in an MCI are more transparent and the resulting medication and transport of the injured is more efficient. The introduction of RFID enhanced patient tags leads to various usability ...

Interacting with Activity Streams (2011)

Whereas activity streams are intensively used in the Web 2.0, they are not well established in the context of enterprises, yet. The user centered activity stream concept has to be modified before it is efficiently usable for enterprises. Simple and effective information classification and filtering is essential for assessing specific pieces of information in enterprises. As soon as the first enthusiasm about enterprise 2.0 fades away, integration of existing business processes becomes a crucial part of usable activity streams. ...

Assessing qualitative usability in life-threatening, time-critical and unstable situations (2011)

We developed a heuristic for assessing the usability of user-interfaces in lifethreating, time-critical and unstable situations in a qualitative way. The major advantages of our approach as opposed to standardized quantitative questionnaires is the independence from a baseline, the possibility to make absolute statements and the potential for adaptations. When creating a qualitative semi structured interview we adhere to the common modus operandi of the qualitative social research. On the basis of 17 common quantitative questionnaires on usability we defined the five major categories Utility, Intuitiveness, ...

Exploring Multi-touch Gestures for Map Interaction in Mass Casualty Incidents (2011)

In mass casualty incidents a common operation picture, which gives an overview about the current situation is critical information for managing the emergency. In order to support the collaboration between different incident commanders a multi-touch table, placed in the incident command post, is used to present the current operation picture on a map. To place as little additional mental load as possible on the users, any interaction with this map interface should be natural and intuitive. Therefore we investigated in a user study several alternative multi-touch gestures, combined to five sets for ...

Indirect Tracking of Patients in Mass Casualty Incidents (2010)

In MCIs (mass casualty incidents) patient tracking is cumbersome when using paper based approaches. Due to the fact that the spatial positions of the patients are essential in MCIs, we equipped the relief workers with electronic devices. We analyzed two concepts for patient tracking: direct and indirect tracking. The indirect tracking turned out to be superior with regard to the requirements from Feuerwehr TUM (Technische Universität München). An implementation and evaluation of this concept was performed within the scope of the SpeedUp project. This project focuses on the development ...

Design, Implementation and Evaluation of User-Interfaces for life-threatening, time-critical and unstable Situations (2010)

A mass casualty incident (MCI) is an emergency situation in which various circumstances lead to a great number of injured patients at the same place that cannot be immediately medicated by the regular rescue service. The fact that the regional rescue service reaches its limits leads to an abrupt and spontaneous change of the organizational structures. In order to better assist the operation controllers in their crucial decisions by well-founded information, innovations in the field of user-interfaces are a necessity. The relief units have to pass instantaneously all the available information to ...

Beyond Pinch-to-Zoom: Exploring Alternative Multi-touch Gestures for Map Interaction (2010)

Interaction with virtual maps is a common task on tabletop interfaces, particularly in the context of command-andcontrol applications. In nearly all cases, widely known gestures such as pinch-to-zoom are employed. To explore alternatives and variations of this mode of interaction, we have defined five alternative gesture sets for the tasks of modifying the map view and selecting map objects in an emergency management scenario. We present the results of an explorative study conducted with user interface experts, domain experts and inexperienced randomly selected users.

Development and evaluation of a virtual reality patient simulation (VRPS) (2009)

In disasters and mass casualty incidents (MCIs) paramedics initially determine the severeness of all patients' injuries during the so-called triage. In order to enhance disaster preparedness continuous training of all paramedics is indispensable. Due to the fact that large disaster control exercises are laborious and expensive, additional training on a small scale makes sense. Therefore we designed and developed a virtual reality patient simulation (VRPS) to train paramedics in this disaster triage. The presented approach includes gesture based interactions with the virtual patients in order to ...

Mobile User-Interfaces for Text Input in Time-Critical, Unstable and Life-Threatening Situations (2009)

Paper based documentation sheets are still the basis for documentation and communication in mass casualty incidents. Computer assisted emergency management, however, has huge advantages in assisting rescue workers in the emergency management processes. Entering the patient’s name and first name is rather complicated because they could consist of nearly any character string. Unfortunately none of the standard input modalities can be used when taking the emergency specific requirements for mobile user interfaces into account. In emergency environments an input technique which mostly works with ...
