- Walk-in-Place is an established locomotion technique for walking in virtual environments, as it incorporates body motion similar to regular walking. Although there is extensive research on the performance and experience of walking in virtual reality spaces, it typically requires minimal-to-moderate physical movement, e.g., stepping forward and turning around, to explore virtual spaces. Therefore, the question we ask ourselves in this work is how user experience and performance are affected when the user is actively moving in place. In this paper, we explored three body-steering methods for jogging-in-place in virtual environments: (1) head-, (2) hand-, and (3) torso-based. To investigate the performance of the proposed body-steering methods for jogging in virtual reality, we conducted a controlled lab experiment (N = 12) to assess task completion time, number of steps, and VR sickness. We discovered that hand- and torso-based methods require fewer steps than the head-based method, and the torso-based is slower than the other two. Moreover, the number of collisions and virtual reality sickness were comparable among the methods.

Konferensbidrag (refereegranskat)abstract
- The Human Resource (HR) area has made little use of innovative technologies to develop its processes, routines and education. However, we believe that digital tools such as Virtual Reality (VR) can play an important role in developing social aspects of work. We have investigated Human Resource Development Professionals’ (HRD-Ps’) perception of using a VR-prototype for training of social skills in the workplace. A digital three-dimensional world was designed for the study participants, in which they interacted with agents to train social skills in the workplace. Study participants explored a VR-prototype through the usage of head-mounted devices (HMD). We collected the designer’s description of the intended design element of the VR prototype and pre- and post-intervention questionnaire from the study participants and conducted a top-down thematic analysis. The three intended design elements 1) focus on the training experience, 2) learning-depth through emotional response for engagement and motivation, and 3) perspective-taking enabled by game design, were confirmed and reflected upon by the HRD-Ps’. Additionally, using VR for social skills training in the workplace was recognized as innovative, and could have the capacity to position an organization as being in the forefront of digitalization. The conclusion is that VR has a potential to create engagement and provide insights in HR matters, but further studies are needed to show the full power and potential in using VR for HR matters.

Looking for quality in trash : data quality in IoT litter-bins
- 2023
-
Ingår i: ECIS 2023.
-
Konferensbidrag (refereegranskat)abstract
- Internet of Things (IoT) holds significant potential for municipal efficiency and effectiveness. It enables subsystems to seamlessly communicate and permits their integration into a connected whole, affording new opportunities for value creation. In this paper, we present a study of municipal litter-bins that have been retrofitted with sensors to convey data on trash volume in each receptacle. Based on interviews, strategy documents, and notes from project meetings, we analyse their implementation from a data quality perspective and reflect on social- and technical issues. The case illustrates the propensity and consequences of overestimating benefits and oversimplifying technical interventions. This paper contributes to our practical understanding of socio-technical implications of technology use in the public sector in general and the deployment of IoT for smart cities in particular.

Konferensbidrag (refereegranskat)abstract
- The 2030 Agenda has pushed practitioners as well as academia to renew their efforts on promotingsustainability, e.g. in how digital technologies can support cities to improve their environmentalperformance. However, as scholars focus their attention on the positive outcomes of implementation,they often neglect the environmental impact of the artefact itself. We present a study of a Green ISimplementation – a municipal Internet of Things (IoT) solution which was expected to decrease thecarbon emissions produced by urban waste collection in Sweden. Using a mixed methods approach,we present qualitative findings from interviews & project meetings as well as quantitative findingsfrom a Life Cycle Assessment (LCA). We find that (1) the environmental impact of the connectedlitter-bins – however small – is not necessarily offset by any significant benefits, and (2) the mostsignificant way for the stakeholders to reduce environmental impact is to utilize more ecologicallyfriendly trash bags.

Bokkapitel (refereegranskat)abstract
- Social entrepreneurship and responsibility have grown in societies in recent decades. The purpose of this article is to investigate and discuss social entrepreneurship in relation to the SDGs within municipalities in sparsely populated areas in Sweden. Specifically, this article explores how politicians and officials in municipalities view social entrepreneurship, what challenges municipalities face in creating sustainable development, and how municipalities can develop conditions for collaborations between public actors and private companies in order to achieve more sustainable development within the municipality. To this end, close to 40 different stakeholders were interviewed within 15 municipalities in 2 regions in the middle of Sweden. The results illustrate that little attention was paid to the use of social entrepreneurship in these communities and regions. There is also little knowledge regarding the very concept of social entrepreneurship among municipal officials and politicians. Instead, strong focus is placed on creating jobs in the municipalities, where social entrepreneurship can play an important role. Meanwhile, sparsely populated municipalities face challenges in the form of an aging population and population decline. Furthermore, there is also a lack of competence. The companies, for their part, are aware of the important role they play in creating sustainable development in the municipality. The companies employ a large proportion and need skills. From all this, the conclusion is drawn that collaboration between different actors is necessary to create sustainable development.

The connected, sustainable and inclusive society : IoT implementation in a Swedish municipality
- 2022
-
Ingår i: E3S Web of Conferences. - : EDP Sciences. ; 349
-
Konferensbidrag (refereegranskat)abstract
- The Internet of Things (IoT) is expected to transform the way we live, work, and learn. Using IoT could thus be a game-changer for municipalities towards sustainability. The Swedish municipality of Södertälje strives to develop IoT concepts and use open data for a sustainable and inclusive society. The goal of this study was to explore how IoT can enable route optimization and placement planning for increased operational efficiency. The goal was also to enhance the knowledge of the environmental and social benefits of IoT systems in the waste collection system in Södertälje. The analysis is based on Life Cycle Assessment (LCA) and interviews. The results show a minor climate change impact for the IoT solutions in the overall smart waste collection system. The major climate impact contributor was instead associated with the trash bags used. Additionally, the study showed that the performance of the system relies on smart planning of the operations and the transportations.

Using 360-degree videos for virtual reality exposure in CBT for panic disorder with agoraphobia : A feasibility study
- 2022
-
Ingår i: Behavioural and Cognitive Psychotherapy. - : Cambridge University Press (CUP). - 1352-4658 .- 1469-1833. ; 50:2, s. 158-170

Tidskriftsartikel (refereegranskat)abstract
- Background: Cognitive behavioural therapy (CBT) is an effective treatment for panic disorder with agoraphobia (PDA). However, implementation of some of the procedures involved, particularly in vivo exposure, can be time consuming and taxing for routine health care services. CBT with exposure taking place in virtual reality (VR-CBT) is a more time-efficient option and has shown promising results in the treatment of PDA. However, VR-CBT requires expensive equipment and appropriate virtual environments, which historically has been costly and cumbersome to produce. Thus, access to VR-CBT has been sparse in regular care environments. Aims: The aim of this study was to investigate whether VR-CBT using filmed virtual environments produced with a low-cost 360-degree film camera can be a feasible and acceptable treatment for PDA when implemented in a primary care context. Method: This was an open feasibility trial with a within-group design, with assessments conducted at pre-test, post-test, and 6-month follow-up. Participants (n = 12) received a 10-12 week treatment programme of VR-CBT and PDA-related symptoms were assessed by the primary outcome measure The Mobility Inventory for Agoraphobia (MIA) and the Panic-Disorder Severity Scale-Self Rated (PDSS-SR). Results: The results showed that treatment satisfaction was high and participants were significantly improved on PDA-related measures at post-treatment and at 6-month follow-up with large effect sizes (Cohen's d range = 1.46-2.82). All 12 participants completed the treatment. Conclusions: These findings suggest that VR-CBT with 360-degree video virtual environments delivered to primary care patients with PDA is feasible, acceptable, and potentially efficacious.

Konferensbidrag (refereegranskat)abstract
- We here present a series of design explorations focusing on batteryless interactions powered by hand cranking body movements. The explorations concern not only the matter of powering but also the use of human physical engagement for controlling interactive systems, as well as how to support designers in testing, exploring, and making such interactions. This pictorial illustrates contributions concerned with the embodied and electro-physical prototyping of such experiences, in addition to our efforts to facilitate such design work through new technical tools.

On the role of forests and the forest sector for climate change mitigation in Sweden
- 2022

Ingår i: GCB Bioenergy. - : Wiley. - 1757-1707 .- 1757-1693. ; 14:7, s. 793-813

Tidskriftsartikel (refereegranskat)abstract
- We analyse the short- and long-term consequences for atmospheric greenhouse gas (GHG) concentrations of forest management strategies and forest product uses in Sweden by comparing the modelled consequences of forest resource use vs. increased conservation at different levels of GHG savings from carbon sequestration and product substitution with bioenergy and other forest products. Increased forest set-asides for conservation resulted in larger GHG reductions only in the short term and only when substitution effects were low. In all other cases, forest use was more beneficial. In all scenarios, annual carbon dioxide (CO2) sequestration rates declined in conservation forests as they mature, eventually approaching a steady state. Forest set-asides are thus associated with increasing opportunity costs corresponding to foregone wood production and associated mitigation losses. Substitution and sequestration rates under all other forest management strategies rise, providing support for sustained harvest and cumulative mitigation gains. The impact of increased fertilization was everywhere beneficial to the climate and surpassed the mitigation potential of the other scenarios. Climate change can have large—positive or negative—influence on outcomes. Despite uncertainties, the results indicate potentially large benefits from forest use for wood production. These benefits, however, are not clearly linked with forestry in UNFCCC reporting, and the European Union's Land Use, Land-Use Change and Forestry carbon accounting, framework may even prevent their full realization. These reporting and accounting frameworks may further have the consequence of encouraging land set-asides and reduced forest use at the expense of future biomass production. Further, carbon leakage and resulting biodiversity impacts due to increased use of more GHG-intensive products, including imported products associated with deforestation and land degradation, are inadequately assessed. Considerable opportunity to better mobilize the climate change mitigation potential of Swedish forests therefore remains.
