Conference paper (peer-reviewed)abstract
- Motion-based games offer positive effects on physical, social, and mental health for the players and have been common during the past decade, enabled by commercial motion tracking devices. However, little is known about the impact of game mechanics on the player experience, movement, and performance in motion-based games. In this paper we present results from a study with 35 participants comparing two different game mechanics, one reactive and one strategic, for a casual motion-based game. The assumption was that a more strategic mechanic would lead to less movement but more enjoyment. However, there was no significant difference in player experience, performance, or movement between the two game mechanics. In addition, a key aspect for the players preferred game mechanics was the perceived amount of thinking the game mechanic required.

Digitalized Co-production of Emergency Response : Using Volunteers as First Responders
- 2024
-
Licentiate thesis (other academic/artistic)abstract
- Contemporary global challenges like global warming, rapid urban development, and the current unstable security situation, lead to an increase in large-scale crises (e.g., forest fires) alongside frequent smaller emergencies (e.g., house fires and traffic accidents). The increase in emergencies strains professional response organizations, necessitating additional resources. Civilian volunteers are therefore increasingly being integrated into the response system. The development is mediated by information and communication technologies (ICTs) which enable communication between professional responders (e.g., the municipal rescue services, the emergency medical services, the Public Swedish Answering Point) and citizens. While many studies focus on spontaneous volunteer activities emerging on social media, fewer examine organized volunteerism initiatives at the local emergency response level. Over a decade ago, a municipal rescue service in northern Sweden established an initiative recruiting volunteers as first responders and equipping them with basic response tools. The volunteers undergo training in tasks such as cardiopulmonary resuscitation (CPR) and fire extinguishing. They are dispatched to predefined response tasks using simple ICT applications like SMS lists or mobile apps. This initiative has expanded to other areas due to perceived benefits such as shorter response times and reduced casualties and material damage. The phenomenon can be labelled as an emerging form of ICT-enabled or digitalized co-production of public services. However, previous research indicates a research gap in understanding, describing, and defining this type of co-production. The overall aim of the thesis is to describe how these ICT-enabled initiatives emerge and develop over time and identify the related effects on the response system. This is expected to provide recommendations on how they can be developed and supported. This aim is divided into three specific objectives, where each has been addressed through a research paper: 1- identifying how the existing literature describes ICT-enabled/digitalized volunteerism in large- and small-scale emergencies, 2- identifying how these initiatives emerge and operate, and can be maintained in small-scale emergencies, introducing more systematized knowledge on this concept, 3- initially evaluating the contributions of volunteers in the initiatives. Leaning on a case study approach inspired by action research, a combination of data collection methods has been adopted, e.g., a literature review, interviews, and incident reports filled out by volunteers. For the data analysis, the theoretical lens of ICT-enabled/digitalized co-production of public services has been applied. The first paper is a literature review study that examines digitally enabled volunteering activities in crises and small-scale emergencies. It highlights the prevalence of studies on volunteers using social media for crowdsourcing in crises, often termed digitalized volunteerism which entails virtual and, or physical contributions by volunteers to the response efforts. In contrast, fewer studies focus on volunteers' role in local small-scale emergencies, labelled as "hybrid" ICT-enabled or digitalized coproduction. The term hybrid here refers to the loose affiliation of the volunteers where they collaborate with the rescue services but are not officially associated through binding contracts. Hence, they are in between spontaneous and organized volunteerism. Both volunteering modes support professional response systems and display similar needs for steering, financial support, coordination, and integration of ICT artifacts. However, crises require increased coordination to manage uncertainties, risks, and data overload effectively. The second paper presents three models describing the emergence of hybrid digitalized co-production initiatives in urban and rural areas, as defined in Paper 1, along with how national authorities can support them. These models i.e., Rural, Urban, and National consist of three phases: Recruitment, Response, and Maintenance. Each model exhibits distinct characteristics. In rural areas for example, there is a need for more regular training due to low alerting frequency, and the possibility of using simple dispatch ICTs as cost-effective solutions. Conversely, urban areas have more alerts, necessitating more advanced ICTs, with less emphasis on regular training compared to rural areas. At the macro-level, the national model highlights roles that national actors can play such as facilitating a joint Application Programming Interface (API), joint insurance solutions, and an ICT system that can register incoming and active volunteers. The third paper is an initial evaluation of these initiatives at emergency sites, focusing on ICT-enabled dispatch, estimated response times, tasks performed, and collaboration with professionals, to assess the effects of using volunteers. This approach contrasts with previous studies that took an overall perspective and only used qualitative data. A total of 53 incident reports were collected from volunteers, revealing that volunteers arrived before professionals in twothirds of incidents, contributing to an average gain of 5 minutes. Additionally, volunteers performed a broader range of tasks than previously described, and often continued collaboration with professionals on-site, despite the initial expectation of handing over tasks upon the arrival of professional response actors. Also, comparing this data with the rural model from Paper 2, similarities and differences emerged. For instance, there was a higher number of alerts, and the basic ICTs used for dispatch were deemed insufficient, contrary to the model's perception. The thesis’ scientific contribution is a clearer conception of digitalized co-production of, above all, local emergency response as an emerging phenomenon. In the three papers, the ICT dispatch was identified as central and needs further development to enhance this co-production form. The thesis also sheds light on the need to integrate the initiatives into the official governmental frameworks. Furthermore, the thesis provides a primary understanding of how the concept works on the ground and provides an initial evaluation of the effects. In the practical field, the thesis offers insights into the importance of volunteers as additional resources to the official response systems, highlights challenges, hindrances, and enablers, and suggests potential solutions and improvements. Future work will include a further collection of incident reports for more reliable assessments and complementary interviews with volunteers. Also, the potential role of volunteers in larger crises, for example, as part of civil preparedness, will be further explored.

Sensor Requirements for Logistics Analysis of Emergency Incident Sites
- 2020
-
In: Proceedings of the 17th ISCRAM Conference. - : Information Systems for Crisis Response and Management. - 9781949373271 ; , s. 952-960
-
Conference paper (peer-reviewed)abstract
- Using sensors to collect data at emergency incident sites can facilitate analysis of the logistic operations. This can be used to improve planning and preparedness for new operations. Furthermore, real-time information from the sensors can serve as operational decision support. In this work in progress, we investigate the requirements on the sensors, and on the sensor data, to facilitate such an analysis. Through observations of exercises, the potential of using sensors for data collection is explored, and the requirements are considered. The results show that the potential benefits are significant, especially for tracking patients, and understanding the interaction between the response actors. However, the sensors need to be quite advanced in order to capture the necessary data.

Cognitive design of a digital desk for the emergency room setting
- 2014
-
In: AMIA Annual Symposium Proceedings. - 1942-597X. ; 2014, s. 274-281
-
Journal article (peer-reviewed)abstract
- Digital desk technology has a still mainly unexplored potential to support the everyday work of collaborating clinicians. This paper presents ER Desk - a digital desk that was designed to specifically support a team of healthcare professionals working in an emergency room setting. The underlying design requirements were elicited in a comprehensive distributed cognition study of paper-based practices in an emergency room of a middle-sized Swedish hospital. We present the user interface and visualization requirements for digital desks for small clinical emergency room teams. Moreover, we discuss key design issues more generally with a focus on supporting team awareness, cognition, and collaborative routines of healthcare personnel working in clinical environments such as emergency rooms and intensive care units.

Framtidens skadeplats : intervjuer med landstingens beredskapssamordnare
- 2016
-
Reports (other academic/artistic)abstract
- Syftet med föreliggande studie var att genom intervjuer med beredskapssamordnare från Sveriges landsting försöka skapa en bild av hur uppfattningen var att skadeplatsen såg ut idag och skulle kunna kommat att förändras på sikt. Vidare önskade intervjustudien söka svar på frågor som rörde komplexiteten på skadeplatsen genom att diskutera ledningsförhållanden, samverkan med andra aktörer, alarmerings- och dirigeringsfunktionernas roll i det svenska sjukvårdsystemet samt hur ett möjligt arbete med ett återtagande av förmågan till ett civilt försvar skulle påverka systemet i sin helhet. Överlag har detta syfte uppnåtts genom ett rikt material kring relevanta frågeställningar som belyst ett flertal kritiska aspekter både i dagens situation men även för framtiden.Resultatet ger en relativt entydig bild av hur situationen uppfattas på landstingsnivå idag av personalen som behandlar beredskapsfrågorna. Den bild som målas upp fokuserar kanske främst på en upplevd avsaknad av centrala och nationellt övergripande styrningar vilket menligt påverkar förmågan att lyfta ledningsförmågan från regional till nationell nivå vid en större händelse som överstiger den regionala förmågan. Den svenska modellen för att hantera samhällsstörningar av idag är väl anpassad för att hantera händelser inom ramen för det egna länets geografiska område. Befintliga koncept för samverkan och samordning bedöms fungera bra i vardagen, exempelvis vid de vanligaste fallen av skadeplatser: trafik och brand. Detta innebär dock att systemet fungerar väl under förutsättning att händelsen är begränsad i såväl tid och rum som vad avser antalet drabbade. En större händelse eller flera händelser samtidigt på olika platser, särskilt om det finns försvårande faktorer såsom utsläpp av farliga ämnen eller en högre hotbild, skapar försvårande omständigheter som upplevs svårhanterliga idag. I ett framtida scenario upplevs även risken för dessa händelser och terrorattacker att öka. Avhängigheten av IT samt ett samhälle som i allt högre grad förlitar sig på ”just in time”-leveranser gör att sårbarheten har ökat och upplevs fortsätta göra det även i framtiden. Andra viktiga områden som lyfts är nuvarande och befarad framtida brist på kompetent personal samt att utbildnings- och övningsverksamhet inte kan bedrivas i önskvärd utsträckning, delvis på grund av personalbrist och –omsättning.Vidare syns den generella uppfattningen vara att det saknas ett tydligt ledarskap på nationell nivå då det sällan, om alls, utkommer några direkta styrningar rörande vad som skall uppnås och i vilken utsträckning. Detta har också påvisats i avsnittet ovan rörande före-, under- och efterperspektivet där det finns en klart övervägande del synpunkter på de två förstnämnda perspektiven. Nationell styrning är alltså något som uppfattas vara efterfrågat och då inte bara avseende ledning under insats utan även i frågor rörande enhetlig utrustning och metodik samt utbildnings- och övningsfrågor. Få respondenter har tagit upp efterperspektivet i någon större utsträckning men då det har förekommit har det framförallt berört erfarenhetshanteringsfrågor och den brist som upplevs finnas inom detta specifika område idag. Erfarenheter från den egna verksamheten, såväl i vardagen som vid insatser vid allvarliga händelser, behöver tas om hand, följas upp och sedan utgöra grund för ett levande utvecklingsarbete.

Battlefield trauma care
- 2018
-
In: Proceedings of the Human Factors and Ergonomics Society 62nd Annual Meeting. - : Sage Publications. ; , s. 634-638
-
Conference paper (peer-reviewed)abstract
- Introduction: Rapid and structured medical care is important to increase wounded patients’ chances of survival in modern warfare. This requires a functioning medical chain. Aim: The aim of this study was to expand the knowledge of how the battlefield trauma care affects patient outcome in situations with a large number of casualties in the Swedish armed forces. Methods: An empirical study with a convergent parallel mixed methods design, which included observations and semi-structured interviews. Results: The results show that the trauma care performed at Role 1-units functioned well. The most prominent issue discovered was deficiency in transportation resources for medical evacuation throughout the entire medical chain. Conclusion: Despite that the trauma care performed at Role 1-units functions well, casualties are at risk for preventable complications or death. Improved transportation logistics are required to improve the medical capabilities of the Swedish armed forces.

The importance of using the designated duty officers when assessing the medical response organization
- 2017
-
Conference paper (other academic/artistic)abstract
- BackgroundAn important aspect of disaster medicine is to be proactive and respond quickly when disaster strikes. In Sweden, the role responsible for swift medical response on the regional level is the designated duty officer.MethodsA large exercise to assess national medical response ability was conducted. Seven medical regional staffs (a total of 93 individuals participated as tested participants) were involved in handling a large train accident scenario. The exercise was run for 5 hours, where the different regional staffs were located at their regular command posts. The exercise was organized using Emergo Train Systems.ResultsSeveral capabilities were identified during the exercise as important for the organization to maintain the ability to handle a similar event: documentation and operational picture, communication and terminology, command of resources, strategy for distribution of resources, national co-ordination, and exercise development.The designated duty officers were central to the exercise in several aspects: 1) in developing and verifying a realistic scenario and preparing background information, 2) as participants in the exercise, 3) assessors of the staffs’ behaviors, and 4) as domain experts when interpreting the exercise outcome.ConclusionsUsing subject matter experts is central to many research domains. However, the more complex a situation is the larger the demand of expertise is. The technical platform allows for coordinating complex exercises, whereas the subject matter expert in terms of the designated duty officer is required to guarantee validity and reliability in these large-scale exercises.Key messages:Running complex scenarios to train and test abilities requires subject matter experts in both planning, preparation, implementation, and assessment.Sophisticated simulator and training platforms, such as Emergo Train Systems, facilitates while the designated duty officers are necessary to guarantee validity and reliability in the exercise.

The relationship between Workload, Teamwork, Situation Awareness, and Performance in Teams A microworld study
- 2011
-
In: Proceedings of the Human Factors and Ergonomics Society Annual Meeting. - : Sage Publications. - 1541-9312. ; , s. 851-855
-
Conference paper (peer-reviewed)abstract
- In modern military organizations teamwork performance is central, yet the underlying factors contributing to such performance are debated. The purpose of this paper was to investigate how several known teamwork measures relate to a prior model of operator performance (Nählinder et al, 2004). This study expands this model to the team level and in the command and control domain. Specifically, this paper studies the relationship between individual and team workload measures, situation awareness measures, and performance measures in 18 two-person teams. The study has two major findings: Firstly, the various team cognition measures statistically cluster into four meaningful concepts (workload, teamwork, situation awareness and performance). Secondly, a Structural Equation Model indicates that the relationship between the various individual and team measures can be described in a model resembling the model found in previous studies (Nählinder et al, 2004). In particular, the results show that the general workload in the microworld study has a negative effect on both teamwork and situation awareness. Teamwork, in turn, also affects situation awareness, which has major impact on performance.

Intracorporeal suturing: Transfer from Fundamentals of Laparoscopic Surgery to cadavers results in substantial increase in mental workload
- 2015
-
In: Surgery. - : Elsevier. - 0039-6060 .- 1532-7361. ; 158:5, s. 1428-1433
-
Journal article (peer-reviewed)abstract
- INTRODUCTION:A spatial secondary task developed by the authors was used to measure the mental workload of the participant when transferring suturing skills from a box simulator to more realistic surgical conditions using a fresh cadaver. We hypothesized that laparoscopic suturing on genuine bowel would be more challenging than on the Fundamentals of Laparoscopic Surgery (FLS)-simulated bowel as reflected in differences on both suturing and secondary task scores.METHODS:We trained 14 surgical assistant students to FLS proficiency in intracorporeal suturing. Participants practiced suturing on the FLS box for 30 minutes and then were tested on both the FLS box and the bowel of a fresh cadaver using the spatial, secondary dual-task conditions developed by the authors.RESULTS:Suturing times increased by >333% when moving from the FLS platform to the cadaver F(1,13) = 44.04, P < .001. The increased completion times were accompanied by a 70% decrease in secondary task scores, F(1,13) = 21.21, P < .001.CONCLUSION:The mental workload associated with intracorporeal suturing increases dramatically when trainees transfer from the FLS platform to human tissue under more realistic conditions of suturing. The increase in mental workload is indexed by both an increase in suturing times and a decrease in the ability to attend to the secondary task.
