- We have deposited Ti-Si-C thin films using high-power impulse magnetron sputtering (HIPIMS) from a Ti3SiC2 compound target. The as-deposited films were composite materials with TiC as the main crystalline constituent. X-ray diffraction and photoelectron spectroscopy indicated that they also contained amorphous SiC, and for films deposited on inclined substrates, crystalline Ti5Si3Cx. The film morphology was dense and flat, while films deposited with dc magnetron sputtering under comparable conditions were rough and porous. Due to the high degree of ionization of the sputtered species obtained in HIPIMS, it is possible to control the film composition, in particular the C content, by tuning the substrate inclination angle, the Ar process pressure, and the bias voltage.

- This paper presents the initial results from a project that aimed to collect visitor data at a traveling exhibition starting at the Regional Museum in Kristianstad, Sweden during 2014-2016. The project was intended also to contribute to the creation of an atmosphere “About time”, which was the subject of the exhibit. We built a system that was integrated as an interactable part of the exhibition by using elements of quiz game mechanics in combination with elements of data based tracking applications and elements of visual art installations. The data provides statistics which are used to visualize the current status of the visitors’ attitude toward specific questions about time, imprinting the visitors themselves an integral part of the exhibition. Visitors build a visual Game Ego when answering questions and at the same time provided statistical data that can be monitored and extracted from the system. The results show that we succeeded to some degree but more can be done towards incorporating game design elements to engage the user, such as feedback and challenge.

Spelforskning i Sverige : LevelUp projektrapport
- 2024
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Rapporten bygger på tre delstudier med olika datainsamlingstekniker:En bibliometristudie av svensk spelforskning baserad på data från Scopus respektive SwePub.En enkätstudie över svenska spelforskningsmiljöer.En intervjustudie om svenska spelforskarmiljöer.Bibliometristudiens ansats har varit bred. Materialet inkluderar därmed även poster som endast har en perifer koppling till spel, men returnerar i fallet SwePub färre än 3000 poster. Spelforskning bedrivs på många lärosäten i Sverige och publiceras inom många ämnesområden. Totalt 95 forskare har en publicering som omfattar 10 eller fler spelpublikationer1. Det finns starka lokala kluster av forskare som sampublicerar men sampubliceringen mellan svenska och nordiska lärosäten är inte så omfattande. Jämfört med Finland har Sverige färre publikationer med ett tydligt fokus på spelforskning.Enkätstudien visar att spelforskarmiljöerna oftast består av ett antal forskare med olika ämnesmässig bakgrund där de själva definierar sig som spelforskare snarare än att organisationen som sådan gör det. Miljöerna har sammantaget och högt räknat runt 30 aktiva doktorander men siffran är osäker. 94% av respondenterna anger att deras forskning ligger inom ”spel för andra områden än underhållning” och endast 6% anger ”spelteknikfokus”. 44% anger ”spelbranschen”. Det är tydligt att spel för just underhållning inte ligger fokus för svensk spelforskning. Detta är remarkabelt då den svenska datorspelsindustrin är en multimiljardindustri fokuserad på just spel som underhållning. Det finns alltså en mycket stor diskrepans mellan industri och svensk spelforskning.Intervjustudien ger en bild av att spelforskningen bedrivs inom splittrade miljöer, av forskare med olika ämnesmässig bakgrund. Det finns en tydlig upplevd brist på forskningsfinansiering inom adekvata områden och det finns brister i de finansieringsinstrument som finns idag. Detta påverkar såväl vilken typ av forskning som kan bedrivas inom spel och rekryteringen av forskarstuderande. Respondenterna är överlag mycket positivt inställda till idén om en nationell forskarskola. Flera ser också Svenska Spelforskarrådet som en viktig aktör för att stärka svensk spelforskning både nationellt och internationellt.Rekommendationer:Det bör finnas en tydligare egen hemvist för forskning och utbildning inom spel för att tydliggöra kärnan i området.Fokus för forskningen behöver förändras så att spel för underhållning kommer mer i fokus.Finansieringsinstrumenten för spelforskning behöver förändras för att möjliggöra en sådan förändring.En nationell forskarskola inom spel bör inrättas.Det finns anledning att lära av framgångsrika miljöer i Finland och Danmark.

- Games for health is one of the most prominent areas for serious games, i.e. games with a purpose beyond only entertainment. The purpose of a health game may be to inform about health related issues; promote healthy lifestyles and even to drive behavioral change. This paper outlines the initial game design considerations and some future research directions for a game focusing on cardiovascular health. As the overall aim of the project is to promote a healthy lifestyle through diet and physical activity to prevent future cardiovascular disease, we focused on “taking care of your heart” as the basis for the game. Hence we call the game Happy Heart and use a heart symbol as a non-playable character (NPC) that the player needs to take care of. To some extent we are inspired by the electronic Tamagochi toys (Bandai) where players need to take care of a digital pet. The heart symbol is universal and is also an ideograph that expresses the concept of love and as such it transcends language barriers.The burden of non-communicable diseases (NCD) is rapidly increasing across the world. Today they are the main drivers of morbidity, disability, and mortality in low- and middle income countries (LMICs), and are expected to increase due to unhealthy lifestyles in the wake of ongoing societal changes [1]. Among the major risk factors in many LMICs are poor diet, insufficient physical activity, tobacco and alcohol consumption, and exposure to hazardous substances, e.g. from air pollution. LMICs currently contribute three quarters of the deaths from NCD.Among the NCD, cardiovascular diseases are the most common cause of hospitalization in Nepal [1]. Digitalization and collaboration with the education sector (e.g. community schools) in health promotion interventions could further improve children’s behavior by targeting factors that affect their lifestyle outside the family environment [4]. Hence, the Digital Game Based Learning approach.

- In serious game development, graphic design needs to be eye-catching, while also depicting subject matter content in a responsible, accurate, and clear way. Previous research has shown that abstract and symbolic game visuals seem to be preferable for learning and providing an engaging experience. Our research focuses on describing the challenges involved in creating effective visual communication through game graphics in cross cultures. In particular, we’re interested in examining if certain styles of visual communication are more or less effective between different cultural demographics. To examine this, we have created a serious game which aims to promote healthy food and nutrition habits to teenagers in both Nepalese and Swedish schools and by doing so also motivate behavioral changes toward healthier eating habits. We are currently conducting studies to see whether preferences and image recognition differ between the two demographical spheres. This paper will only discuss the exploratory study done in Nepal. Ultimately, this paper aims to contribute development guidelines that can aid developers in creating more effective visual communication in their serious games, and we primarily focus on exploring what we call the compromise of ‘clarity’ and ‘appeal’ in the creation of game graphics. We present an initial model for choosing at what level in terms of realism/abstraction and taxonomic hierarchy the graphical components of serious games optimally should be produced in order to solve the dilemma of precise, unmistakable, yet appealing visuals in serious games. It all comes down to two primary decisions: defining the taxonomic hierarchy of the items to depict, and choosing the style in which to depict them. With a better understanding of when different game visuals are more or less appropriate, both in terms of style and in which objects are represented, game developers will be able to balance production costs better while also creating something that strikes the compromise between clarity and appeal.

Game graphics and effective learning : A review of visual communication research in serious games
- 2022

Ingår i: Proceedings of the International Conferences Interfaces and Human Computer Interaction 2022, Game and Entertainment Technologies 2022. - : IADIS Press. - 9789898704412 ; , s. 165-173

- The visuals of a game is a crucial element when it comes to providing good player experiences. Visuals are also an incredibly complex subject in a game context since different modes of visual representation can be more or less “appropriate” for different settings. For example, while one can look at photo-realism as an impressive feature of a game due to its technical complexity and functionally accurate representation of real-world objects, it might still not be a fitting choice for different audiences, or for different pedagogical strategies. Serious game research seldom focuses on understanding the design of these components or their applicability to different types of learning, and it more often focuses on games’ mechanics and how well they manage to capture subject matter content while still being engaging. The aim of this paper is to explore the gap in visual communication research, describing what studies tend to focus on providing some valuable context. This review was conducted on papers that dealt with visual aspects of serious games. The results show that visual communication is rarely addressed in serious game development research. Future research would benefit from taking visual communication in detail to facilitate the effectiveness of serious games.

- An important factor for success in project-based learning (PBL) is that the involved project groups establish an atmosphere of social interaction in their working environment. In PBL-scenarios situated in distributed environments, most of a group's work-processes are mediated through the use of production-focused tools that are unconcerned with the important informal and social aspects of a project. On the other hand, there are plenty of tools and platforms that focus on doing the opposite and mainly support informal bonding (e.g., Facebook), but these types of environments can be obtrusive and contain distractions that can be detrimental to a group's productivity and are thus often excluded from working environments. The aim of this paper is to examine how a game-based multi-user environment (MUVE) can be designed to support project-based learning by bridging the gap between productivity-focused and social software. To explore this, the authors developed a game-based MUVE which was evaluated in a PBL-scenario. The result of the study revealed several crucial design elements that are needed to make such a MUVE work effectively, and that the acceptance towards game-based MUVEs is high, even with a rudimentary execution.

- In this study we report on the film growth and characterization of thin films deposited on amorphous quartz. The experimental studies have been complemented by first-principles density-functional theory metastable Ti-Fe-C film changes. With increasing annealing time, there is a depletion of iron close to the surface of the film, while regions enriched in iron are simultaneously formed deeper into the film. Both the magnetic ordering temperature and the saturation magnetization changes significantly upon annealing. The DFT calculations show that the critical temperature and the magnetic moment both increase with increasing Fe and C-vacancy concentration. The formation of the metastable iron-rich Ti-Fe-C compound is reflected in the strong increase in the magnetic ordering temperature. Eventually, after enough annealing time nanocrystalline -Fe starts to precipitate, the amount and size of which can be controlled by the annealing procedure; after 20 min of annealing, the experimental results indicate a nanocrystalline iron-film embedded in a wear-resistant TiC compound. This conclusion is further supported by transmission electron microscopy studies on epitaxial Ti-Fe-C films deposited on single-crystalline MgO substrates where, upon annealing, an iron film embedded in TiC is formed. Our results suggest that annealing of metastable Ti-Fe-C films can be used as an efficient way of creating a wear-resistant magnetic thin film material. approximately 50-nm-thick Ti-Fe-CDFT calculations. Upon annealing of as-prepared films, the composition of the10 min, nanocrystalline -Fe starts to precipitate, the amount and size of which can be controlled by the annealing procedure; after 20 min of annealing, the experimental results indicate a nanocrystalline iron-film embedded in a wear-resistant TiC compound.

- We have synthesized Ti–Si–C nanocomposite thin films by dc magnetron sputtering from a Ti3SiC2 compound target in an Ar discharge on Si(100), Al2O3(0001), and Al substrates at temperatures from room temperature to 300 °C. Electron microscopy, x-ray diffraction, and x-ray photoelectron spectroscopy showed that the films consisted of nanocrystalline (nc-) TiC and amorphous (a-) SiC, with the possible presence of a small amount of noncarbidic C. The growth mode was columnar, yielding a nodular film-surface morphology. Mechanically, the films exhibited a remarkable ductile behavior. Their nanoindentation hardness and E-modulus values were 20 and 290 GPa, respectively. The electrical resistivity was 330 µ cm for optimal Ar pressure (4 mTorr) and substrate temperature (300 °C). The resulting nc-TiC/a-SiC films performed well as electrical contact material. These films' electrical-contact resistance against Ag was remarkably low, 6 µ at a contact force of 800 N compared to 3.2 µ for Ag against Ag. The chemical stability of the nc-TiC/a-SiC films was excellent, as shown by a Battelle flowing mixed corrosive-gas test, with no N, Cl, or S contaminants entering the bulk of the films.
