In: IADIS International Journal on Computer Science and Information Systems. - Lisbon, Portugal : IADIS Press. - 1646-3692. ; 10:2, s. 95-112

Journal article (peer-reviewed)abstract
- The aim of the project presented in this paper is that visually impaired and sighted players should be able to play the same game and share a gaming experience. The goal is that the game should be accessible to visually impaired players without any additional tools, such as text-to-speech, that may reduce the immersion. At the same time, sighted players should perceive the game as a regular game. This paper presents an evaluation of the game where the player immersion has been evaluated through a post test immersion questionnaire. The study was conducted with three independent groups: sighted players using graphics (n=10), blindfolded sighted players (n=10) and visually impaired players (n=9). Although progress in the game and the reported sense of control differed between groups, player immersion was very high in all groups. There were differences between the three groups only in one out of five immersion factors. The result shows that it has been possible to provide an immersive experience irrespective of whether the players are playing the game with graphics or using audio only.

PyGPU: A high-level language for high-speed image processing
- 2007
-
In: [Host publication title missing]. - 1646-3692. ; , s. 66-81
-
Conference paper (peer-reviewed)abstract
- Image processing is an area with many computationally demanding algorithms. When implementing an algorithm the programmer has to make the choice of either using a high-level language, thereby gaining rapid development at the expense of run-time performance. Or, using a lower-level language having higher runtime performance, but also a higher implementation cost. In this paper we present PyGPU, an embedded language that enables image processing algorithms to be written in the highlevel, object-oriented language Python. PyGPU functions are compiled to execute on the graphics processing unit (GPU) present on modern graphics cards, a streaming processor capable of speeds more than a magnitude higher than those of current generation CPUs. We demonstrate a number of common image processing algorithms, showing how these can be implemented succinctly and clearly using high-level abstractions, while at the same time achieving high performance.

Unraveling perceptions of barriers to digital transformation : contrasting small and medium-sized with large enterprises
- 2023
-
In: IADIS International Journal on Computer Science and Information Systems. - : IADIS Press. - 1646-3692. ; 18:1, s. 102-119
-
Journal article (peer-reviewed)abstract
- With the proliferation of contemporary digital technologies, Digital Transformation (DT) has become a significant theme for companies across almost all industries. DT encompasses the digitalization of internal processes, the provision of digital services and products, and the enhancement of the customer experience. Previous research has delved into different barriers that impede successful DT. In our study, we investigate further how these barriers are perceived by employees at small and medium-sized enterprises (SMEs) in contrast to larger enterprises (LEs). We employ a mixed-methods approach by performing a quantitative analysis using the Means, Mann-Whitney U test with effect size and integrating it with qualitative results converted into frequencies. Our empirical data consist of two samples consisting of participants from 189 SMEs and 221 LEs for quantitative analysis and participants from 238 SMEs and 281 LEs for qualitative analysis. Overall, the results suggest a relatively similar perception of DT processes, indicating culture and structure as major barriers. However, the establishment of resources dedicated to managing DT emerges as a vaster barrier for SMEs than for LEs. At the same time, SMEs face fewer barriers regarding general personnel resources.

State of Gender Equality in and by Artificial Intelligence
- 2022
-
In: IADIS International Journal on Computer Science and Information Systems. - : IADIS. - 1646-3692. ; 17:2, s. 31-48

Journal article (peer-reviewed)abstract
- When talking about sustainability, we usually think that it is only about safeguarding the environment; nothing is further from reality. Of course, the environment is a crucial component of sustainability and our survival, but it is important to recall that the society and the economy play important roles in this regard, and without the interconnection and development of these three perspectives it will not be possible to achieve sustainable progress. The Sustainable Development Goals (SDGs) established by the United Nations (UN) defend this idea and address the main challenges that humanity faces. One of these challenges is gender equality, which is identified in the perspective of social sustainability through SDG 5. Gender equality is a very complex and difficult challenge to address due to the great cultural diversity of our society. Thus, achieving this goal will require laying a solid foundation and working together by combining very different fields of knowledge. In this sense, Artificial Intelligence (AI) is one of the fields that is currently having the greatest impact and relevance for the development of new technologies and for the advancement of numerous areas. This growing evolution of AI demonstrates that its repercussions at the social level must be analyzed and addressed in such a way that AI becomes a positive asset for sustainability and, in this particular case, for gender equality.For all these reasons, this study aims to analyze the current state of the art and collect the existing knowledge in the fields of AI and gender equality, by conducting a Systematic Mapping Study (SMS). The obtained results and findings have allowed us to identify the most relevant advances in this regard, as well as the gaps and drawbacks that currently exist and on which we must urgently focus to address gender equality both in and by AI. In the same way, these findings demonstrate the limited joint development of both fields, but also indicate an increase in the relevance and the number of proposals that these fields are receiving in recent years.

System representations formats and their influence on user experience evaluations
- 2018
-
In: IADIS International Journal on Computer Science and Information Systems. - Lisbon : IADIS Press. - 1646-3692. ; 13:1, s. 96-109
-
Journal article (peer-reviewed)abstract
- Knowledge is lacking on the choice and use of representations in a design process when seeking to investigate user experiences. Two types of representations (a storyboard and an interactive prototype) of the same system were used in a user experience evaluation involving 24 participants to investigate how different representation formats influence participants' responses to interactive systems. Data from a questionnaire and individual interviews were compared. Very few differences in questionnaire responses were found. However, the interactive prototype gave rise to more design proposals as well as more personal reflections on experiences although with a focus on interface design details. The storyboard elicited more responses on the core ideas of the concept, but less grounded in reflections on personal use. The differences are attributed to how each representation managed to convey interactivity and context, resulting in differences in experienced agency. It is therefore suggested that there is a need for further research, but with less focus on the type of system representation and more focus on how the content and affordances of system representations can be designed to elicit rich and personal reflections on user experience in early design phases.

Challenges and Opportunities with Information System Support for Healthcare Processes : a Healthcare Practitioner Perspective
- 2015
-
In: Proceedings of the 8th IADIS International Conference Information Systems 2015, IS 2015. - : IADIS Press. - 9789898533333 ; 10:1, s. 80-96

Conference paper (peer-reviewed)abstract
- Healthcare processes require the cooperation of different healthcare providers and medical disciplines. In such an environment, the quality and safety of care rely heavily on the ability to exchange information from one software to another, and from one person to another. However, information systems that support a seamless flow of information along healthcare processes are not broadly used in healthcare environments. Usually, healthcare organizations have their own autonomously developed information systems that do not support the cooperation of different organizational units and medical disciplines. This has led to the fragmentation of the patients’ information in proprietary heterogeneous systems across healthcare organizations. The aim of this paper is to: (1) explore how healthcare practitioners´ in Sweden experience information system support in their daily work activities, and (2) present and illustrate how key design principles of a process support system prototype can support healthcare practitioners in their work practice. An important conclusion from this research is that a process support as the one described in this paper creates new opportunities to organize and coordinate healthcare

Process oriented information systems : A key to evidence based medicine
- 2015
-
In: IADIS International Journal on Computer Science and Information Systems. - : IADIS Press. - 1646-3692. ; 10:1, s. 64-79
-
Journal article (peer-reviewed)abstract
- The primary and basic component of healthcare is information. Being a healthcare practitioner involves using medical knowledge and patient information to deliver the best possible care. When decisions about the care of the patient are made they must as far as possible be based on research-derived evidence rather than on clinical skills and experience alone. This decision process is complex as evidence is infrequently available in a form that can be acted upon at the time decisions must be made. The aim of this paper is to present and illustrate how a prototype visualization of a process support system can support the availability of relevant medical knowledge in a way which seamlessly integrates with healthcare practitioners work practice, and thereby enables healthcare practitioners to work in accordance with EBM. An important conclusion from this research is that a process support as the one described in this paper can reshape the practice of EBM.
