Ein konzeptuelles Modell für Kommunikationsstrategien in Krisen basierend auf dem subjektiven Unsicherheitsgefühl der Bevölkerung (2016)

Kristian Rother, Inga Karl and Simon Nestler

In diesem Beitrag wird ein erstes Modell entwickelt, welches das Verhältnis zwischen subjektivem Unsicherheitsgefühl und der objektiven Existenz einer Krisensituation aufzeigt. Anhand des Modells werden Normstrategien für die Kommunikation von Behörden und Organisationen mit Sicherheitsaufgaben festgelegt sowie der typische Verlauf einer Krise dargestellt. Das Modell wurde argumentativ konstruiert und soll vor allem als Diskussionsgrundlage dienen.

Ein Konzept für die Klassifizierung subjektiver Sicherheit in Tweets (2016)

Kristian Rother, Inga Karl and Simon Nestler

In diesem Beitrag wird die erste Iteration eines Prozesses zur Konzeption einer Annotationsrichtlinie zur Klassifizierung von Tweets hinsichtlich des in ihnen ausgedrückten subjektiven Sicherheitsgefühls dargelegt. Basierend auf einer initialen, rudimentären Annotationsrichtlinie wurden Tweets von vier Annotatoren klassifiziert. Diese Klassifizierung wurde zu einem späteren Zeitpunkt wiederholt und die Annotationen wurden hinsichtlich der Interrater- und Intrarater-Reliabilität untersucht. Anhand qualita- tiver Interviews wurden Handlungsempfehlungen für die Überarbeitung der Annotationsrichtlinie abgeleitet.

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

Kristian Rother, Inga Karl and Simon Nestler

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.

Towards Virtual Reality Crisis Simulation as a Tool for Usability Testing of Crisis Related Interactive Systems (2015)

Kristian Rother, Inga Karl and Simon Nestler

Usability testing is expensive in some domains due to the resource requirements that go hand in hand with taking a complex context of use into account. Crisis-related research is one such domain, typically requiring the reenactment of an extensive crisis scenario. To lessen the resource requirements and provide a more exible setup geared towards testing, crisis scenarios can be reconstructed as virtual reality simulations. This paper outlines the development of an initial prototype of such a simulation following the design science method. The prototype is used to test if injecting an item that will be tested into the simulation affects the realism of the virtual reality crisis simulation. The realism was measured in a within-subject experiment and equivalence tests showed that injecting a representation of a simple app had no signi cant in uence on the realism of the simulation.

Crisis-Related Apps: Assistance for Critical and Emergency Situations (2015)

Inga Karl, Kristian Rother and Simon Nestler

In this paper the authors developed applications for apps in times of crises and critical situations. They analyzed how people act in these situations and how to mitigate their uncertainty and fears through situation-specific communication. Including these aspects as well as the general challenges of crisis communication, pros and cons of apps based on existing examples were discussed. The resulting requirements for an app for crises and dangerous situations should assist in designing a communication solution that strengthens the feeling of security of citizens in critical times, such as life-threatening situations. This solution is intended as an additional means of communication for emergency services to modernize crisis communication with affected people.

Social Media als Mittel der Krisenkommunikation (2014)

Simon Nestler

Social Media sind im privaten Umfeld und in Unternehmen weit verbreitet. Im Bereich der Krisenkommunikation herrscht noch Skepsis gegenüber den sozialen Medien. Wenn grundlegende Anforderungen berücksichtigt werden, bieten Social Media großes Potential für die Krisenkommunikation. Die Anforderungen lassen sich dabei am Besten in Form einer eigenen Social Media Plattform umsetzen. Eine solche Plattform verbessert die Kommunikation, Koordination und Kooperation in Krisen. Gleichzeitig werden Betroffene und Hilfsbereite aktiv eingebunden und miteinander vernetzt. Das Potential von sozialen Medien ergibt sich dabei auch aus der Möglichkeit, Unsicherheiten in der Bevölkerung gezielter adressieren zu können. Langfristig ist eine eigene Social Media Plattform eine kostengünstige Ergänzung zur personalintensiveren Telefonhotline.

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

Simon Nestler

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 complex: The usa- bility tests have to be smoothly integrated in the crisis scenario. In crisis scenarios realism leads to an overproportional need for resources. This publication gives an overview on concepts for usability testing in crisis scenarios. These usability tests facilitate an iterative improvement of interactive systems. This concept is not limited to a methodical examination of the usability test itself. Usability testing is considered from HCI perspective and from the perspective of crisis management. This combined analysis leads to a more systematic approach to usability testing in crisis situations. The proposed approach increases the frequency of usability tests without increasing the overall effort.

Nutzung von sozialen Medien als bürgerzentriertes Frühwarnsystem für Krisensituationen (2014)

Inga Karl and Simon Nestler

In Krisensituationen müssen Behörden die Sicherheitslage in der Bevölkerung schnell abschätzen können, um geeignete Maßnahmen für die Bewältigung der Gefahr vorzunehmen. Der vorliegende Ansatz zum Erfassen des subjektiven Sicherheitsgefühls der Bürger beschreibt den Einbezug sozialer Medien in den Prozess der Krisenkommunikation. Indem der Informationsaustausch zwischen den Bürgern auf Facebook, Twitter und Co. in Echtzeit erfasst und analysiert wird, können Unsicherheiten und Ängste in der Bevölkerung frühzeitig lokalisiert werden. Die Visualisierung solcher Informationen stellt eine überblicksartige Zusammenfassung über die Kommunikation der Bürger in gegen wärtigen Krisensituationen dar und dient Behörden als eine soziale Frühwarnkomponente.

Inga Karl and Simon Nestler

IDie Krisenkommunikation stellt Behörden vor die schwierige Aufgabe Bürger über die Krise zu informieren und aufzuklären. Das vorliegende Paper beschreibt einen Ansatz für eine mobile Kollaborationsplattform, die sowohl krisenspezifische Informationen an die Bürger als auch einen Eindruck über die Situation der Bürger an die Behörden vermittelt. Das Konzept bezieht dabei soziale Medien sowie bereits existierende Lösungen für mobile Krisenkommunikation und Interaktion ein. Bei der Herleitung von ersten Umsetzungsvorschlägen dient eine Diskussion verschiedener Anforderungen an die Kollaborationsplattform.

aperto - Ein Rahmenwerk zur Auswahl, Einführung und Optimierung von Corporate Social Software (2012)

Alexander Richter, Michael Koch, Sebastian Behrendt, Simon Nestler, Sebastian Müller and Stephan Herrlich

Der Einsatz von Social Software zur Unterstützung der Zusammenarbeit in und zwischen Unternehmen gewinnt seit mehreren Jahren zunehmend an Bedeutung. Gleichzeitig machen die Charakteristika von Social Software - allen voran deren sogenannte Nutzungsoffenheit - ein Umdenken notwendig. Corporate Social Software unterscheidet sich eklatant von traditionellen betrieblichen Anwendungssystemen, denen bereits bei ihrer Entwicklung klare Strukturen und vorher vorgegebene bzw. definierte Nutzungsszenarien zugrunde liegen. Klassische Vorgehensweisen der Anforderungsanalyse betrieblicher Anwendungssoftware, des IT-Change Management und der IT-Evaluation können hier nur noch bedingt oder gar nicht weiterhelfen. Im vorliegenden Beitrag wird das aperto-Rahmenwerk, bestehend aus dem aperto-Fünf-Ebenen-Modell, der CUP-Matrix sowie den daraus entwickelten Werk-zeugen vorgestellt. Es ermöglicht die vollständige und konsistente Kategorisierung und Klassifizierung der Nutzungspotentiale von Corporate Social Software und un-terstützt somit deren Auswahl, Einführung und Optimierung. Das im Beitrag beschriebene Vorgehen kam in den letzten Monaten mehrfach erfolgreich in Auswahl- und Einführungsprojekten deutscher Unternehmen zum Einsatz.

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

Eva Artinger, Patrick Maier, Tayfur Coskun, Simon Nestler, Mareike Maehler, Yeliz Yildirim-Krannig, Fabian Wucholt, Florian Echtler and Gudrun Klinker

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 and intuitive user interfaces in unstable, time- critical emergency situations. Taking the requirements into consideration we developed a concept to overcome the MCI through the combination of multiple devices. The devices are carefully chosen according to the task of the EMS personnel in the field as well as in the incident command post. Three different interfaces – PDAs for the rescue units in the field, tablet PCs for the incident commanders and a multitouch table in the incident command post – help the entire rescue team to gain efficient situational awareness.

RFID based Patient Registration in Mass Casualty Incidents (2011)

Simon Nestler, Eva Artinger, Tayfur Coskun, Thomas Endres and Gudrun Klinker

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 challenges which are discussed in this paper. Furthermore three different implementations show, how these challenges can be solved in the future. These solutions have been evaluated in a disaster control exercise in order to get an impression of the practical suitability of the proposed solutions. The future introduction of RFID tags in rescue and emergency services can be based on this work.

Interacting with Activity Streams (2011)

Simon Nestler, Benjamin Elixmann and Stephan Herrlich

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. We achieved first research results so far which go along with several interview reports and analyses. In the future standardization could simplify the interaction with existing tools by the means of activity streams. We expect that the way how enterprises use specific tools will become even more important.

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

Simon Nestler, Eva Artinger, Tayfur Coskun, Yeliz Yildirim-Krannig, Sandy Schumann, Mareike Maehler, Fabian Wucholt, Stefan Strohschneider and Gudrun Klinker

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, Memorability, Lernability and Personal Effect. We selected all questions from the questionnaires which are useful for assessing the usability of user-interfaces in emergencies. Furthermore we rephrased the closed-ended questions to open-ended ones. The quantification of research results is possible by weighting the qualitative results in dependence to the research question.

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

Eva Artinger, Tayfur Coskun, Martin Schanzenbach, Florian Echtler, Simon Nestler and Gudrun Klinker

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 the tasks of modifying the map view and selecting map objects in an emergency management scenario. The gesture sets contained widely known as well as new promising gestures.

Indirect Tracking of Patients in Mass Casualty Incidents (2010)

Simon Nestler, Tayfur Coskun, Eva Artinger, Peter Pichlmaier and Gudrun Klinker

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 of strategies for reacting in mass casualty incidents (MCIs) in an appropriate way. In this paper we describe the background, the requirements, the concepts, the implementation and the evaluation. Finally, the results are presented and discussed.

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

Simon Nestler

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 the scene managers by means of mobile user-interfaces. This information circulation should not obstruct the relief units from their various life-saving duties such as triage, medication, registration and transport. Before user-interfaces can be used in life-threatening, time-critical and unstable situations, the environment has to be analyzed in details. Consequently the first part of this work focuses on the operation environment, the users, the computers and the user-interfaces. The specifications of the operation environment concretizes and characterizes the life-threatening, time-critical and unstable situation. The inspections of the users deal with their education, experience, knowledge and tasks. Furthermore, innovative developments in the field of computer technology and the resulting variety of concepts and technologies are presented. Finally a summary of existing concepts and approaches for the development of user-interfaces is given. In the main part of this thesis three different user-interfaces metaphors are examined in detail, for each of them the requirements have been identified in cooperation with the relief workers. On the basis of these requirements different concepts are developed. Afterwards these concepts are implemented and evaluated within the scope of a disaster control exercise. The different user-interfaces focus on training, triage and tracking. All concepts are based on the identified basic conditions regarding environment, users, computers and user-interfaces. The introduction of mobile user-interfaces in hitherto paper-based processes leads to various challenges. Besides the possible fields of application for user-interfaces, this thesis focuses on the possibilities for connecting paper-based and electronic information, for instance by extending the triage tags with rfid-chips, which are electronically readable.

Is it possible to interact with a handheld device while holding it in both hands? (2010)

Tayfur Coskun, Simon Nestler, Eva Artinger, Amal Benzina and Gudrun Klinker

Intuitiveness, attractiveness and efficiency are in general important characteristics of high quality User Interfaces (UI). In the case of a Mass Casualty Incident (MCI) and other life threatening situations good user interfaces are essential as every second counts in these time-critical situations. Finding the best way to interact with the system is a challenge with many open issues. Therefore, it is essential to test different UI alternatives to determine important usability issues as those mentioned before. This paper focuses on the research question how patients can be selected on a map application which runs on a rugged tablet PC. A rugged tablet PC is in general heavy because of its robustness, which introduces a new special requirement in addition to the existing UI requirements. Consequently, since the users are forced to hold the tablet PC with two hands because of its heaviness, they have to perform all UI interaction with the thumbs. This implies that the users are not able to reach every item on the screen of the tablet PC. Therefore all UI elements have to be either on the left or on the right hand-side of the screen. The implementation and the evaluation of the UI alternatives presented in this paper were performed within the scope of the SpeedUp project.

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

Eva Artinger, Martin Schanzenbach, Florian Echtler, Simon Nestler, Tayfur Coskun and Gudrun Klinker

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.

Timing Concept for Assistance of Anticipatory Driving (2010)

Darya Popiv, Mariana Rakic, Klaus-Josef Bengler, Heiner Bubb and Simon Nestler

Driving maneuvers are supported by advanced driver assistance systems (ADAS) within the limits of currently available on-board sensors which recognize driving situations. The recent emergence of new sources providing additional traffic information poses further outlooks on the extension of the anticipation horizon of driving assistance systems. This paper focuses on the timing aspects of ADAS. The presented concept identifies the proper point in time for presenting anticipatory information to the driver. The timing concept is based on early anticipation of driving situations by the system and correctly timed activation of the driver assistance which supports the driver in performing phases of deceleration.

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

Simon Nestler, Manuel Huber, Florian Echtler, Andreas Dollinger and Gudrun Klinker

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 simulate the triage process as realistically as possible. The evaluated approach focuses on the training of paramedics in disaster triage according to the mSTaRT (modified Simple Triage and Rapid Treatment) triage algorithm on a multi-touch table top device. At the Munich fire department fully-qualified paramedics performed 160 triage processes with the triage simulation. The accuracy of the triage processes was compared to previous disaster control exercises with real mimes. The presented results of this explorative evaluation will be the basis for future, larger evaluations.

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

Simon Nestler and Gudrun Klinker

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 only one hand is required. When using hand-helds in emergencies a stylus cannot be used for various reasons. The developement of a fast and intuitive user interface for text input on the basis of the given requirements is the first step toward a mobile user interface for emergency operations.

Mobile computing in mass casualty incidents (MCIs) (2009)

Simon Nestler and Gudrun Klinker

This paper illustrates the future role of mobile computing for the response in emergencies and mass casualty incidents (MCIs). Furthermore it describes the different components and functionalities which will be needed - in the form of a vision. This vision shows that a mobile system is capable to assist emergency teams and incident commanders in MCI operations. This mobile system has to contain functionalities such as information on patients, information on the scene, information on emergency teams, information on infrastructure, MCI knowledge, technical support, management tools, remote collaboration and flexibility. Due to the fact that various researchers performed research on these challenges a wide-spread overview on the state of the art is presented. Finally this paper points out that a powerful user-interface which considers the unstable, time-critical and life-threatening context is indispensable for the successful introduction of mobile computing in emergencies and MCIs.

Common Interaction Schemes for In-Vehicle User-Interfaces (2009)

Simon Nestler, Marcus Tönnis and Gudrun Klinker

In this paper different interaction schemes which are currently implemented by major automotive manufacturers have been identified and analyzed. Complete overviews on all in-vehicle user-interface concepts are rarely spread. This paper gives a deeper insight in interaction schemes and user-interface concepts which are implemented in current cars. Additionally an expert review with 7 experts was performed to get a first impression which user-interface interaction schemes work well in the in-vehicle context. In order to get an impression of the suitability of the interaction schemes for the development of usable in-vehicle user-interfaces we performed different tests. The results are reported in text and tables.

Hybrid approach for management of patient-related information in mass casualty incidents (2009)

Simon Nestler, Manuel Huber, Gudrun Klinker

This work demonstrates how a combination of paper based and electronic objects can improve information access in mass casualty incidents. At the moment paptient-related information is documented on Paper Based Patient Tags (PBPTs) which are attached to every patient. Current research in the field focuses on the introduction of RFID based patient tags (RBPTs) which depend on more compex tools or even on wireless networks. We propose to improve the rlief workers' documentation task by combining PBPTs with RBPTs. This combination, which we call RFID Enhanced Patient Tags (REPTs), is capable of combining advantages from both approaches. On the paper part, paramedics can easily scribble down medical results, it can be read and extended easily by succeeding relief units, colored paper bares can be identified even from far away, and for extending patient record information, nothing but a pen is needed. The use of electronically readable tags enables the paramedics to log their patient contacts, provide the incident commanders with evolving information to acquire the patient location and to review information on previously triaged or medicated patients. Using our implementaiton, all Disaster Control Data can be stored electronically on REPTs and continous wireless communication is not mandatory anymore. Furthermore, all Patient Data can be stored handwritten on REPTs and complex electronic input of textual information is not necessary.

Concept for visualizing concealed objects to improve the driver's anticipation (2009)

Simon Nestler, Markus Duschl, Darya Popiv, Mariana Rakic and Gudrun Klinker

Current advanced driver assistance systems (e.g. Emergency Brake Assistance, Lane Departure Warning, Lane Keeping Assistance and Blind Spot Detection) assist the driver in reacting to time-critical and unstable situations in a proper way. However, the anticipation of situations which are lying in the farer future is currently left primarily to the driver. In this paper, we present visualization concepts for concealed objects in order to support smart deceleration. Smart deceleration requires the anticipation of future traffic condition and the assistance of the driver in performing deceleration phases efficiently. In addition, safety is increased by reduction of potential criticality through the early deceleration phase. We have identified and categorized situations in which a broader anticipation is possible: situations with permanent obstacles, situations with temporarily stopped vehicles and situations with slower driving vehicles. An important issue when presenting information to the driver is the identification of the most suitable perspective. For visualizing the traffic situation in the surroundings of the driver's car we established a virtual bird-eye perspective (VBEP), showing the traffic scene from a 3D viewpoint that is slightly raised above the driver and rigidly tethered to the car. This VBEP is a powerful concept to draw the driver's attention to situations in the further future. On the basis of this concept we developed different visualizations and integrated them in the digital instrument cluster between the speedometer and the revolution counter.

Supporting Casual Interactions between Board Games on Public Tabletop Displays and Mobile Devices (2009)

Florian Echtler, Simon Nestler, Andreas Dippon and Gudrun Klinker

As more interactive surfaces enter public life, casual interactions from passersby are bound to increase. Most of these users can be expected to carry a mobile phone or PDA, which nowadays offers significant computing capabilities of its own. This offers new possibilities for interaction between these users’ private displays and large public ones. In this paper, we present a system which supports such casual interactions. We first explore a method to track mobile phones that are placed on a horizontal interactive surface by examining the shadows which are cast on the surface. This approach detects the presence of a mobile device, as opposed to any other opaque object, through the signal strength emitted by the built-in Bluetooth transceiver without requiring any modifications to the devices’ software or hardware. We then go on to investigate interaction between a Sudoku game running in parallel on the public display and on mobile devices carried by passing users. Mobile users can join a running game by placing their devices on a designated area. The only requirement is that the device is in discoverable Bluetooth mode. After a specific device has been recognized, a client software is sent to the device which then enables the user to interact with the running game. Finally, we explore the results of a study which we conducted to determine the effectiveness and intrusiveness of interactions between users on the tabletop and users with mobile devices.

Einsatzorganisation in Katastrophen: Unterstützung von Einsatzkräften durch mobile User Interfaces (2008)

Simon Nestler

Bei sogenannten Großschadensereignissen wie Bus- oder Eisenbahnunfällen, Großbränden oder Terroranschlägen kommen auf die Rettungskräfte durch den Massenanfall von Verletzten (MANV) besondere logistische Herausforderungen zu. Die Verletzten müssen von der Einsatzleitstelle auf alle erreichbaren Krankenhäuser entsprechend der dort vorhandenen Kapazitäten und der Schwere der Verletzungen verteilt werden. Die Triage durch einen Notarzt oder speziell ausgebildete Rettungsassistenten entscheidet darüber, ob der Patient zunächst vor Ort behandelt werden kann oder umgehend ins Krankenhaus transportiert werden muss. Dieses Buch analysiert die Struktur der Katastrophenbewältigung und zeigt Schwachpunkte im derzeitgen Informationsflusses auf. Anhand eines prototypischen Systems wird demonstriert, wie Einsatzkräfte in Katastrophenfällen zukünftig besser unterstützt werden können. Das vorgestellte Konzept beinhaltet die Ausstattung von Einsatzkräften mit mobilen Geräten, um alle relevanten Informationen zeitnah zum Schadensereignis in elektronischer Form erfassen zu können. Mit Hilfe der am Unglücksort gewonnenen Daten kann so die Koordination der weiteren Versorgung erleichtert werden.

Collaborative problem solving on mobile hand-held devices and stationary multi-touch interfaces (2008)

Simon Nestler, Florian Echtler, Andreas Dippon and Gudrun Klinker

This paper focuses on the coupling of mobile hand-helds with a stationary multi-touch table top device for collaborative purposes. For different fields of application, such as the health care domain, the coupling of these two technologies is promising. For the example of sudoku puzzles we evaluated the collaboration between multi-touch table top devices and mobile hand-helds. During the small-scale evaluation we focused on the differences between face-to-face collaboration and remote collaboration when solving problems collaboratively on table top devices and hand-helds.

Towards adaptive user-interfaces: Developing mobile user-interfaces for the health care domain (2007)

Simon Nestler and Gudrun Klinker

This paper focuses on the development of mobile user-interfaces for disaster scenarios. We propose different concepts how unpredictable and unstable situations can be controlled with the use of adaptive mobile user interfaces. These concepts contribute to the development of more intuitive and adaptive mobile user-interfaces in disaster scenarios. Furthermore we identify possibilities for the improvement of existing mobile user-interfaces in more stable environments with less critical requirements. We point out how presentation of as much information as required and as little information as possible can be achieved by taking the current situation of the users into account. A specific view on the database is presented to each user individually depending on his current duties and responsibilities. In the health care domain different types of information are required by potential users, such as static, patient related and environmental information. The intention of this paper is to stress the importance of adequate mobile user-interfaces in health care applications and to propose how this demand can be met at the best.

Using Mobile Hand-Held Computers in Disasters (2007)

Simon Nestler and Gudrun Klinker

This paper discusses the design and prototypical implementation of a mobile user-interface to assist paramedics in disaster operations based on the mSTaRT triage algorithm. Due to the increasing use of algorithms in the disaster management the introduction of mobile hand-held computers stands to reason. The triage algorithm has been implemented on hand-held computers and tested in a disaster control exercise to evaluate its functionality in real situations. Since mobile, computer-based triage systems for paramedics must not delay the care taking procedures, the major indicator to measure the performance was the time needed by the proposed system as opposed to current paper based methods. The evaluation results were positive.

Design and Development of Virtual Patients (2007)

Simon Nestler Nestler, Andreas Dollinger, Florian Echtler, Manuel Huber and Gudrun Klinker

This paper discusses the design and prototypical implementation of virtual patients to train paramedics in disaster operations. These virtual patients are presented on a multi-touch table top. The current approach focuses on disaster triage according to the mSTaRT triage algorithm. 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, training on a small scale makes sense. The presented approach includes gesture based interactions to simulate the patients as realistically as possible. This more intuitive interaction results in a more realistic simulation of the patient and a better preparation for the real situation.

Resource management in disasters (2006)

Simon Nestler

In so-called mass casualty incidents such as bus or railway accidents, serious fires or terroristic attacks the relief units are confronted with special logistic challenges. The injured have to be spread over all hospitals within reach according to the available capacities and the seriousness of the patients’ injuries. After the patients have been triaged by an emergency physician or a special instructed paramedic they are transported to the appropriate hospitals. In this diploma thesis the weak points in the work flow are analysed and a prototypical system that supports paramedics in performing the triage process is developed. The relief units are equipped with mobile devices in order to guarantee a prompt acquisition of the required information. The coordination of the further treatment can be facilitated when using this acquired information.
