Hur kan svårighetsprogression användas i skapandet av Puzzlehunts med syfte att uppnå en ökad upplevd känsla av flow hos spelaren? Denna frågeställning behandlas i uppsatsen och problemet som måste lösas är hur man kan bygga upp en ackumulerad kunskap om något vars syfte är att hela tiden tvinga dig att hitta nya lösningar på problem. I mer traditionella spel kan upprepning lära spelaren hur spelmekaniken fungerar. I puzzlehunts kan upprepning av spelmekanik inte användas eftersom målet för varje pussel är att hitta mekaniken som löser problemet. Uppsatsen visar att man genom inlärning av hur man skall tänka för att hitta lösningarna till pusslen kan bygga upp en ackumulerad kunskap hos spelaren och därmed även ha en svårighetsprogression och öka upplevd nivå av flow hos spelaren.

Pervasive games are computer games that build, to various extents, on social interaction as a driving force in the game play, on integration between physical and virtual worlds and on constant access to constantly ongoing games from virtually every existing context (anytime, anywhere gaming). This new genre of computer games presents many challenges for both researchers and industry; one of the most important is how to understand enjoyable player experiences in this new kind of computer gaming. The purpose of this thesis is to identify and explore the mechanisms in pervasive game designs that are of most importance for creating enjoyable Pervasive gaming experiences, and further to translate the findings of the exploration into a playability model for pervasive games. My empirical work focuses on the most important aspects for creating enjoyable player experiences when playing pervasive games. Evaluation methods from the usability and playability area have been deployed in order to identify what factors and aspects the players consider of most importance for their experience when they play pervasive games. Three specific pervasive games have been studied; SupaFly, Pervasive Treasure Hunt and Furiae. Theoretically, the thesis departs from existing knowledge about Playability, and the most prominent and accepted frameworks for understanding player experiences in computer gaming have been considered. Of the existing models and frameworks, the GameFlow model was selected as a theoretical point of departure. The main contribution of the thesis consists of a model for understanding player enjoyment in pervasive games - the Pervasive GameFlow model. Pervasive GameFlow elaborates the GameFlow model by adding 14 new criteria identified in the empirical evaluations of three pervasive games, criteria of great importance for enjoyable Player experiences in pervasive games. Further, the thesis answers questions concerning how the players are putting the anytime, anywhere and mobility aspects of pervasive games into practice - how they perceive and handle games that offer constantly ongoing game play. The results also provide insights into the reach or impact of the novel Pervasive aspects of pervasive games and their importance for the players and player experiences. Finally, the thesis provides notes on how evaluation of pervasive games should be performed.

This diploma thesis "New urban games and their players" treats the new phenomenon of urban games. The text is based on the classical games theory joined with the latest developments in the area and some relevant concepts of urban sociology. From a sociological point of view this thesis explores urban games as a new leisure time phenomenon and clearly states its characteristics as well as its definition. The main focus lies in examining the recent developments in Czech urban games and describing the variety present in urban games today. Other related topics of urban activities are also explained. The mechanics of urban games is explored in the case study of Compagnie, an urban game that took place in Prague in 2010. In the case study, the urban game basics are shown in order to help the general public to understand it. This work is concluded with a socio-demographic analysis of urban game players based on an enquiry done with the participants of the game. The whole text mixes theoretic approach with practical study of urban games, sociological analysis and participatory observation.

While much attention in location-based game and wearable research is about their benefits as in-class education or is aimed at children, rather less research has been done about the combination of location-based games and wearables in private use. This paper investigates a game solution for the low history knowledge of German teenagers and focuses on the learning success of the combination of a proposed location-based mobile game and wearable, called ‘Geocation’ for educational purposes as well as the enjoyment of it. Two prototype sets, functional and appearance, about the location-relevant topic ‘King Ludwig II’ were created and tested with 36 teenagers in Munich. To analyze the learning success pre-and post-test surveys were conducted and applied to the strategy of gamification. The enjoyment of the combination of the location-based mobile game and wearable was evaluated by connecting it to the GameFlow theory and conducting post-test interviews. The study has shown that the connected wearable was not crucial for the player’s learning success; however, it contributed to the user’s motivation and enjoyment.

In a recent pilot study, it was revealed that certain players of Pokémon Go did not account for the game while asked to specify the games they played regularly, although they had previously mentioned that they play the game daily. This paper will explore those player’s perception of Pokémon Go in aim to understand why they did not account for the game. This study uses a series of interviews of the participants to explore how they perceive the game. The interviews are analysed thematically using predefined themes and the results suggests that the reason to why the game was not accounted for might be related to the pervasive nature of the game.

This thesis focuses on how location-based games can be used to experience places of cultural heritage in new ways. A prototype game was created in which players follow a day in the life of a sergeant while walking to different locations at Karlsborg fortress and unravel a plot about the plan to steal Sweden’s gold reserve. To analyze how well a location-based game worked in this setting gameflow theory was used to measure the player experience, focusing on how concentration and immersion was handled. Since players will switch their focus a lot between the game and their surroundings it is important that the game helps them know what to concentrate on and stay immersed during the game. A small testing session was conducted at Karlsborg fortress which showed an indication that players were able to stay immersed while playing the game and that the social interaction between players played an important role in their experience.

The aim of this thesis is to compare two different interface approaches for pervasive gameswith a focus on immersion. We designed and created two small pervasive games and implemented bothon two different platforms; smartphone and wearable device. We created four pervasive gameprototypes which we tested with a group of fourteen testers. We subsequently conducted interviewsusing the Repertory Grid Technique. The findings suggest that our testers appreciated wearable devicesmore than smartphones in the context of immersion, while they identified characteristics theyassociated with each platform; Smartphones were considered familiar, inconspicuous, casual but notvery exciting. Wearables were considered a new experience and fun but also strange and attention-drawing.

Online gaming has over the years become very popular and during the global pandemic of 2019, gained an even larger amount of people indulging in the activity. All this online activity has led to a decline in in-person social interactions which have been researched to have negative effects on young adults. This thesis aims to find ways to promote more in-person social interaction with the help of games. An artifact in the form of a video game was created with active video game principles and pervasive game characteristics in mind, with the goal of achieving social interaction between players and spectators. Nintendo Joy-Con controllers are the main controller used and an external microphone to capture sounds is used to fulfill the prerequisites of pervasive games. A collection of five different minigames was created, all with different ways that noise can affect the gameplay. The results of the experiments showed that the artifact promotes in-person social interactions between players and spectators by making the spectators able to interact with the games.

Abstract Modern urban space, technological infrastructure, and sociability combine into a hybrid space that is the arena for urban pervasive games. Over the past two decades the changes in this game arena have been stealthy although substantial. Technological developments have helped to achieve true mobility of gaming devices, increased precision in localization, improved connectivity, and reduced orchestration required per player. Current pervasive location-based games can be played anytime anywhere. Subsequently, doors have been opened for a growing number of commercial games. These changes demand a new conceptualization of the urban game arena. This thesis focuses on playful appropriations of hybrid space. Hybrid space is urban space that entails ubiquitous technologies. Therefore, playful appropriations of hybrid space are always, to some extent, digital as well as urban. Prior research has identified two metaphors for urban pervasive games —true mobility and true sociability. This thesis proposes an additional metaphor, called synchronicity, for binding together different realities in pervasive games. They can be anything from mirror world like realistic virtual environments, such as 3D virtual representations of a city, to abstract realities, such as the backstory of the game, or the space identity of a certain location. While location awareness is an important binding factor between the virtual and physical worlds in pervasive gameplay, synchronizable elements can be anything from encouraged collocated gameplay to semantic similarities between the combined realities. This thesis is based on five game constructs that have been specifically designed and implemented as pervasive research games. Research data has been collected and analyzed with a mixed methods approach from field trials conducted in the wild. Constructive research is complemented with a literature review that maps the characteristics of current location-based mobile games and the game space. The main contribution of this thesis is the identification of the digital, abstract, and physical layers of reality in digital urban pervasive games. The second contribution is the identification and categorization of the synchronizable elements that bind these realities together. This thesis offers initial insights into translating this knowledge into the design of future pervasive games. / Tiivistelmä Urbaanitila on jatkuvassa muutoksessa, sillä se muotoutuu ja järjestyy uudelleen siellä kulkevien kaupunkilaisten kautta. Ubiikin teknologian, ihmisten kanssakäymisen ja modernin tilakäsityksen yhteisvaikutuksesta syntyy niin sanottu hybriditila, joka muodostaa peliareenan monille pervasiivisille peleille. Viime vuosikymmeninä tällä peliareenalla on tapahtunut vaivihkaisia mutta perustavaa laatua olevia muutoksia. Pelilaitteista on tullut aidosti mobiileja, ja ne kulkevat kaikkialla pelaajien mukana. Pelijärjestely vaatii vähemmän vaivaa pelaajaa kohden, paikannuksen tarkkuus on parantunut ja muutosten kautta myös kaupallisia pelejä on enemmän saatavilla. Nykyisiä pervasiivisia sijaintipohjaisia pelejä voi pelata milloin vain ja missä vain. Edellä mainittu kehitys edellyttää pervasiivisten pelien ja pelitilan uudelleen konseptualisointia. Väitöstyön aihe ei ole pelillisyys sellaisenaan, vaan “pelillisyys ja sen hyödyntäminen hybriditilassa”. Hybriditila on aina urbaani ja sisältää ubiikkia teknologiaa, minkä vuoksi pelit tässä tilassa ovat lähes poikkeuksetta myös digitaalisia. Aiempi tutkimus esittää, että saavutetut kehitysaskeleet voi niputtaa kahden metaforan alle. Nämä metaforat ovat: aito mobiilius sekä aito sosiaalisuus. Tämä väitöskirja esittää kolmannen, vielä määrittelemättömän tai saavuttamattoman metaforan näiden jatkoksi: synkronisuus. Synkronisoitavat piirteet tai elementit sitovat todellisuuksia yhteen pervasiivisessa pelitilassa. Tilassa olevat todellisuudet voivat olla realistisia pelimaailman kaltaisia virtuaalitiloja tai abstrakteja todellisuuksia, kuten pelitarinan muodostama todellisuus tai jonkin tietyn paikan tilaidentiteetti. Vaikka sijaintipohjaisuus on tärkeä todellisuuksia yhdistävä piirre, synkronisoitavat elementit voivat olla muutakin kuin sijaintikoordinaatteja. Pervasiiviset pelit nivoutuvat pelaajiensa päivittäiseen elämään, mikä tekee pelin kontekstista erottamattoman osan peliä. Tämä ominaisuus oikeuttaa ”in the wild” -menetelmien käytön tutkimuksessa, mikä tarkoittaa, että pelaamista ja pelejä tarkkaillaan luonnossa todellisessa ympäristössään. Tässä väitöstyössä käytetään konstruktioina varta vasten tätä tutkimusta ajatellen suunniteltuja ja toteutettuja pervasiivisia tutkimuspelejeä. Konstruktiivista tutkimusta tukee lisäksi teoreettinen tutkimusosio, joka koostuu kirjallisuuskatsaukseen pohjautuvasta nykyisten sijaintipohjaisten pelien ja pelitilan kategorisoinnista.
