Mobile virtual worlds

This thesis examines the role of mobile access to virtual worlds in massively multiplayer online role playing games (MMORPG:s). Online gaming worlds have existed for decades, but ever since the smartphone has become more common, new interaction possibilities to these worlds have emerged. We have conducted a literature review to clarify existing gaps in the research community regarding mobile virtual worlds. Through this review, we have constructed a research model containing previously established motivation factors for MMORPG:s, interconnected with possible categories of how to improve the game experience with mobile features. An online survey on this topic was sent out to World of Warcraft players and the results show that many aspects of gameplay through mobile access could improve the gaming experience of virtual gaming worlds. The responses showed very mixed feelings about using many game features from the mobile phone, especially those that tie in with real life. An important finding among the results is the strong reluctance among the players to pay extra money for the addition of mobile access to the virtual world, and a low motivation to use synchronous gameplay features via a mobile computing device

Flawless victory! Investigating search and experience qualities as antecedent predictors of video game success

In recent years, video games have been on the rise as entertainment goods, leading to a growing interest by practitioners, researchers, and, of course, consumers alike. While a few unusually successful video games produce overall high revenues, most released games struggle to break even. Hence, there is an urgent need to better understand what distinguishes fnancially successful games from nonsuccessful video games. Accordingly, several researchers have called for investigations into the drivers of the fnancial success of video games. However, empirical studies within this respect are still lacking. Based on longitudinal data of 351 video games, the current study strives to fll this research gap by investigating the relative importance of potential success factors for the short-term and long-term fnancial success of video games. The results of multiple regression analyses confrm that search qualities such as brand popularity, reviews, and awards as well as experience qualities such as graphics, sound, and game duration signifcantly drive fnancial success in terms of the total number of sold video games in Europe. Consequently, managers in the video game industry can boost their chances for the production of a successful video game by focusing on these factors

Virtual Reality Games for Motor Rehabilitation

This paper presents a fuzzy logic based method to track user satisfaction without the need for devices to monitor users physiological conditions. User satisfaction is the key to any product’s acceptance; computer applications and video games provide a unique opportunity to provide a tailored environment for each user to better suit their needs. We have implemented a non-adaptive fuzzy logic model of emotion, based on the emotional component of the Fuzzy Logic Adaptive Model of Emotion (FLAME) proposed by El-Nasr, to estimate player emotion in UnrealTournament 2004. In this paper we describe the implementation of this system and present the results of one of several play tests. Our research contradicts the current literature that suggests physiological measurements are needed. We show that it is possible to use a software only method to estimate user emotion

Analyzing the Impact of Spatio-Temporal Sensor Resolution on Player Experience in Augmented Reality Games

Along with automating everyday tasks of human life, smartphones have become one of the most popular devices to play video games on due to their interactivity. Smartphones are embedded with various sensors which enhance their ability to adopt new new interaction techniques for video games. These integrated sen- sors, such as motion sensors or location sensors, make the device able to adopt new interaction techniques that enhance usability. However, despite their mobility and embedded sensor capacity, smartphones are limited in processing power and display area compared to desktop computer consoles. When it comes to evaluat- ing Player Experience (PX), players might not have as compelling an experience because the rich graphics environments that a desktop computer can provide are absent on a smartphone. A plausible alternative in this regard can be substituting the virtual game world with a real world game board, perceived through the device camera by rendering the digital artifacts over the camera view. This technology is widely known as Augmented Reality (AR). Smartphone sensors (e.g. GPS, accelerometer, gyro-meter, compass) have enhanced the capability for deploying Augmented Reality technology. AR has been applied to a large number of smartphone games including shooters, casual games, or puzzles. Because AR play environments are viewed through the camera, rendering the digital artifacts consistently and accurately is crucial because the digital characters need to move with respect to sensed orientation, then the accelerometer and gyroscope need to provide su ciently accurate and precise readings to make the game playable. In particular, determining the pose of the camera in space is vital as the appropriate angle to view the rendered digital characters are determined by the pose of the camera. This defines how well the players will be able interact with the digital game characters. Depending in the Quality of Service (QoS) of these sensors, the Player Experience (PX) may vary as the rendering of digital characters are affected by noisy sensors causing a loss of registration. Confronting such problem while developing AR games is di cult in general as it requires creating wide variety of game types, narratives, input modalities as well as user-testing. Moreover, current AR games developers do not have any specific guidelines for developing AR games, and concrete guidelines outlining the tradeoffs between QoS and PX for different genres and interaction techniques are required. My dissertation provides a complete view (a taxonomy) of the spatio-temporal sensor resolution depen- dency of the existing AR games. Four user experiments have been conducted and one experiment is proposed to validate the taxonomy and demonstrate the differential impact of sensor noise on gameplay of different genres of AR games in different aspect of PX. This analysis is performed in the context of a novel instru- mentation technology, which allows the controlled manipulation of QoS on position and orientation sensors. The experimental outcome demonstrated how the QoS of input sensor noise impacts the PX differently while playing AR game of different genre and the key elements creating this differential impact are - the input modality, narrative and game mechanics. Later, concrete guidelines are derived to regulate the sensor QoS as complete set of instructions to develop different genres or AR games

Influence of Psychological Needs and Gaming Motivation on Well-Being of Adult Gamers

Adult online gaming is a fast-growing global entertainment industry, and many gamers spend more time playing games and less time engaging in work or other activities, which negatively affects their lives and relationships. This quantitative study addressed how psychological needs and gaming motivation predicted gaming behavior, life satisfaction, and relationship satisfaction using a mediational model. The theoretical foundation was self-determination theory, which addresses how personal choices are influenced by internal factors, especially psychological needs and motivation. An online survey was used to collect self-reported data from a convenience sample of 935 adult gaming participants using the Basic Needs Satisfaction in General Scale, the Gaming Motivation Scale, the Satisfaction with Life Scale, the Relationship Assessment Scale, and a short demographic questionnaire. Results of multiple regression analyses indicated gaming motivation was a significant mediator of life satisfaction and relationship satisfaction. However, gaming motivation was not a significant mediator of gaming behavior. Findings of this study indicate that for online gamers, quality of life (life satisfaction and relationship satisfaction) is enhanced when gaming motivation is high, suggesting that joy of gaming can positively influence other aspects of life, when psychological needs (autonomy, competence, and relatedness) are positive as well

Derogatory, Racist, and Discriminatory Speech (DRDS) in Video Gaming

Video games have been examined for their effects on cognition, learning, health, and physiological arousal, yet research on social dynamics within video gaming is limited. Studies have documented the presence of derogation, racism, and discrimination in this anonymous medium. However, gamers‟ firsthand experiences are typically examined qualitatively. Thus, this study aimed to establish a quantitative baseline for the frequency of derogatory, racist, and discriminatory speech (DRDS) in gaming. DRDS frequency, sexual harassment, and hate speech measures were administered to 150 individuals from online forums and social media groups. Descriptive and inferential analyses were used to gauge which factors affected DRDS rates. Sex, intergroup and fast-paced game types, time played with others, and identity portrayal showed positive correlations with DRDS. Results indicate an array of complex social and developmental factors contribute to experiencing, perceiving, and personally using DRDS. Implications include psychosocial health impacts similar to everyday harassment, with women being at a higher risk and age as a contributing factor

Designing Location-based Games : How to support players’ social interaction, physical activity and learning about their local environment

The earliest academic studies on location-based games (LBGs) were conducted in the early 2000’s, but the recent upsurge in the popularity and success of commercial LBGs has created a need to re-examine the genre in light of new empirical evidence. In 2016, Pokemon GO brought the LBG genre into a spotlight by being downloaded hundreds of millions of times and generating over 4 billion USD in lifetime revenue to date. Since then, new games such as Jurassic World: Alive, The Walking Dead: Our World and The Witcher: Monster Slayer have emerged. Understanding phenomena related to LBGs is important for various stakeholders from game designers to urban designers and educators. In this dissertation we take an inductive approach to LBG design by gathering evidence from popular commercial LBGs with six original research articles (Studies I-VI). The studies focus on game mechanics that are unique to the LBG genre, and how reported positive outcomes of playing LBGs can be tied to these mechanics. Through the six studies we derive a game mechanics -focused design framework for LBGs, which we name the Triune PoI System, where PoI stands for point of interest. The system consists of three central components: exploration, discovery and navigation, and at the heart of these lies moving to trigger gameplay. The Triune PoI System highlights the importance of LBGs to provide multimodal motivation for players to move and play, and the crucial importance of the playing locations, the PoIs for scaffolding positive outcomes. We demonstrate how the following benefits of playing LBGs (1) physical activity; (2) social interaction; and (3) learning and discovery; are ultimately tied to the Triune PoI System (Studies I-IV). We also investigate the effects of aggressive marketing and LBG game mechanics on players’ well-being (Study V). Here we identify that aggressive marketing can exhaust players, but that the overall LBG playing intensity had a strong significant association with psychological well-being in our sample. We also demonstrate that nostalgia and imagination play crucial roles in scaffolding perceived meaningfulness of playing LBGs (Study VI). Finally, we propose that the popularity of LBGs may be explained by them embodying aspects of the hunter-gatherer lifestyle that are missing in the urban way of living. TIIVISTELMÄ Varhaisimmat akateemiset tutkimukset paikkatietoon pohjautuvista peleistä julkaistiin jo vuosituhannen alussa, mutta pelien viimeaikainen suosio ja kaupallinen menestys antavat aihetta tarkastella paikkatietoon pohjautuvien pelien suunnittelua uuden empiirisen todistusaineiston valossa. Vuonna 2016 julkaistua Pokémon GO:ta on ladattu satoja miljoonia kertoja ja sen suosion inspiroimana on julkaistu sellaisia paikkatietoon pohjautuvia pelejä kuin Jurassic World: Alive, The Walking Dead: Our World sekä The Witcher: Monster Slayer. Näiden pelien ja niihin liittyvien ilmiöiden ymmärtäminen voi olla hyödyllistä monille eri tahoille, kuten pelisuunnittelijoille, kaupunkisuunnittelijoille ja koulutuksesta vastaaville. Tässä väitöskirjatutkimuksessa lähestytään paikkatietoon pohjautuvien pelien suunnittelua induktiivisesti kuuden alkuperäisartikkelin avulla. Tutkimuksessa selvitetään mitkä ovat paikkatietoon pohjautuvien pelien keskeisimmät pelimekaniikat ja miten raportoidut positiiviset vaikutukset nivoutuvat niihin. Tulokset osoittavat, että suosittujen paikkatietoon pohjautuvien pelien keskiössä on ns. "Triune PoI System", joka koostuu 3+1 komponentista: tutkiminen, löytäminen ja navigointi; sekä liikkuminen. Toisin sanoen pelaajat lähtevät tutkimaan ympäristöään, löytävät sieltä mielenkiintoisia kohteita ja navigoivat niiden luokse. Lisäksi pelien keskeisenä elementtinä on pelkästä liikkumisesta palkitseminen. Tutkimuksessa osoitetaan, että liikunta, sosiaalinen vuorovaikutus ja oppiminen on suosituissa peleissä, kuten Pokémon GO:ssa, keskeisesti sidottu Triune PoI Systemiin. Lisäksi selvitetään mitä vaikutuksia kaupallisten paikkatietoon pohjautuvien pelien markkinoinnilla ja mikrotransaktiomekanismeilla on pelaajien hyvinvointiin. Tutkimuksessa havaitaan, että markkinointi saattaa väsyttää pelaajia, mutta kokonaisuutena paikkatietoon pohjautuvien pelien pelaamisella ja hyvinvoinnilla on tilastollisesti merkitsevä vahva yhteys. Lisäksi osoitetaan, että nostalgia ja mielikuvitus tukevat tunnetta pelaamisen merkityksellistä. Lopuksi ehdotetaan, että paikkatietoon pohjautuvien pelien suosiota saattaa selittää niiden tarjoamat metsästäjä-keräilijä-elämän aspektit, joista urbaanissa miljöössä elävät ihmiset jäävät arkielämässään paitsi
