User Experience of Geocaching and Its Application to Tourism and Education

Advances in technology have provided new ways of using entertainment and game technology to foster human interaction. Games and playing with games have always been an important part of people’s everyday lives. Traditionally, human-computer interaction (HCI) research was seen as a psychological cognitive science focused on human factors, with engineering sciences as the computer science part of it. Although cognitive science has made significant progress over the past decade, the influence of people’s emotions on design networks is increasingly important, especially when the primary goal is to challenge and entertain users (Norman 2002). Game developers have explored the key issues in game design and identified that the driving force in the success of games is user experience. User-centered design integrates knowledge of users’ activity practices, needs, and preferences into the design process. Geocaching is a location-based treasure hunt game created by a community of players. Players use GPS (Global Position System) technology to find “treasures” and create their own geocaches; the game can be developed when the players invent caches and used more imagination to creations the caches. This doctoral dissertation explores user experience of geocaching and its applications in tourism and education. Globally, based on the Geocaching.com webpage, geocaching has been played about 180 countries and there are more than 10 million registered geocachers worldwide (Geocaching.com, 25.11.2014). This dissertation develops and presents an interaction model called the GameFlow Experience model that can be used to support the design of treasure hunt applications in tourism and education contexts. The GameFlow Model presents and clarifies various experiences; it provides such experiences in a real-life context, offers desirable design targets to be utilized in service design, and offers a perspective to consider when evaluating the success of adventure game concepts. User-centered game designs have adapted to human factor research in mainstream computing science. For many years, the user-centered design approach has been the most important research field in software development. Research has been focusing on user-centered design in software development such as office programs, but the same ideas and theories that will reflect the needs of a user-centered research are now also being applied to game design (Charles et al. 2005.) For several years, we have seen a growing interest in user experience design. Digital games are experience providers, and game developers need tools to better understand the user experience related to products and services they have created. This thesis aims to present what the user experience is in geocaching and treasure hunt games and how it can be used to develop new concepts for the treasure hunt. Engineers, designers, and researchers should have a clear understanding of what user experience is, what its parts are, and most importantly, how we can influence user satisfaction. In addition, we need to understand how users interact with electronic products and people, and how different elements synergize their experiences. This doctoral dissertation represents pioneering work on the user experience of geocaching and treasure hunt games in the context of tourism and education. The research also provides a model for game developers who are planning treasure hunt concepts.

3D Mesh Simplification. A survey of algorithms and CAD model simplification tests

Simplification of highly detailed CAD models is an important step when CAD models are visualized or by other means utilized in augmented reality applications. Without simplification, CAD models may cause severe processing and storage is- sues especially in mobile devices. In addition, simplified models may have other advantages like better visual clarity or improved reliability when used for visual pose tracking. The geometry of CAD models is invariably presented in form of a 3D mesh. In this paper, we survey mesh simplification algorithms in general and focus especially to algorithms that can be used to simplify CAD models. We test some commonly known algorithms with real world CAD data and characterize some new CAD related simplification algorithms that have not been surveyed in previous mesh simplification reviews.

Influencing Perceived Agency: A Study into User Experiences in Digital Interactive Storytelling

User experience is a crucial element in interactive storytelling, and as such it is important to recognize the different aspects of a positive user experience in an interactive story. Towards that goal, in the first half of this thesis, we will go through the different elements that make up the user experience, with a strong focus on agency. Agency can be understood as the user’s ability to affect the story or the world in which the story is told with interesting and satisfying choices. The freedoms granted by agency are not completely compatible with traditional storytelling, and as such we will also go through some of the issues of agency-centric design philosophies and explore alternate schools of thought. The core purpose of this thesis is to determine the most important aspects of agency with regards to a positive user experience and attempt to find ways for authors to improve the overall quality of user experience in interactive stories. The latter half of this thesis deals with the research conducted on this matter. This research was carried out by analyzing data from an online survey coupled with data gathered by the interactive storytelling system specifically made for this research (Regicide). The most important aspects of this research deal with influencing perceived agency and facilitating an illusion of agency in different ways, and comparing user experiences in these different test environments. The most important findings based on this research include the importance of context-controlled and focused agency and settings in which the agency takes place and the importance of ensuring user-competency within an interactive storytelling system. Another essential conclusion to this research boils down to communication between the user and the system; the goal of influencing perceived agency should primarily be to ensure that the user is aware of all the theoretical agency they possess.

Metrics for Predicting User Behavior and Experience in an Interactive Storytelling System

In much of the previous research into the field of interactive storytelling, the focus has been on the creation of complete systems, then evaluating the performance of those systems based on user experience. Less focus has been placed on finding general solutions to problems that manifest in many different types of interactive storytelling systems. The goal of this thesis was to identify potential candidates for metrics that a system could use to predict player behavior or how players experience the story they are presented with, and to put these metrics to an empirical test. The three metrics that were used were morality, relationships and conflict. The game used for user testing of the metrics, Regicide is an interactive storytelling experience that was created in conjunction with Eero Itkonen. Data, in the forms of internal system data and survey answers, collected through user testing, was used to evaluate hypotheses for each metric. Out of the three chosen metrics, morality performed the best in this study. Though further research and refinement may be required, the results were promising, and point to the conclusion that user responses to questions of morality are a strong predictor for their choices in similar situations later on in the course of an interactive story. A similar examination for user relationships with other characters in the story did not produce promising results, but several problems were recognized in terms of methodology and further research with a better optimized system may yield different results. On the subject of conflict, several aspects, proposed by Ware et al. (2012), were evaluated separately. Results were inconclusive, with the aspect of directness showing the most promise.

Verkkopalveluiden jatkuvan ylläpidon kehittäminen: Case Aucor Oy ja WordPress

Verkkopalveluiden ylläpitovaiheessa halutaan varmistua, etteivät palveluun tehdyt muutokset aiheuta verkkopalvelussa virhetilanteita ja palvelu toimii moitteetta. Muutoksen hyväksyntätestaus voidaan tehdä regressiotestauksena vertaamalla palvelun tilaa ennen ja jälkeen muutoksen. Sisältöpainotteisessa verkkopalvelussa testaaminen keskittyy loppukäyttäjälle esitetyn sivun semanttiseen sekä visuaaliseen oikeellisuuteen sekä erilaisiin toiminnallisiin testeihin. Työssä tarkastellaan etenkin suositulla WordPress-julkaisujärjestelmällä toteutettujen verkkopalveluiden ylläpitoa. Keskeisenä osana julkaisujärjestelmillä toteutettujen verkkopalveluiden ylläpitoa on julkaisujärjestelmän ja sitä täydentävien lisäosien päivittämistä ajantasaisiin versioihin. Nämä päivitykset paitsi tuovat uusia ominaisuuksia verkkopalvelun kehittäjille, myös paikkaavat järjestelmän tietoturvahaavoittuvuuksia sekä korjaavat aiemmissa versioissa esiintyneitä virheitä. Tässä työssä kehitettiin kohdeyrityksen aiempia verkkopalveluiden ylläpitoprosesseja niissä tunnistettujen kehityskohteiden perusteella. Uudistettu kokonaisuus jakautuu kahteen kokonaisuuteen: päivitystarpeen seurantaan sekä päivitysten tekemiseen. Päivitystarpeen seurantaa varten kehitettiin uusi työkalu helpottamaan kokonaiskuvan hahmottamista. Päivitysten tekemisen osalta työssä keskityttiin automatisoidun regressiotestauksen kehittämiseen, missä tärkeimpänä testauskeinona käytetään verkkopalvelusta tallennettujen kuvankaappausten vertailuun perustuvaa visuaalista testausta. Uusien ylläpitoprosesseille määriteltiin myös seurannan kohteet uudistuksen onnistumisen ja jatkokehityksen arviointia varten.

Adherence to Treatment in Psychotic Disorders - Development of user-centered mobile health intervention

The aim of this study was to explore adherence to treatment among people with psychotic disorders through the development of user-centered mobile technology (mHealth) intervention. More specifically, this study investigates treatment adherence as well as mHealth intervention and the factors related to its possible usability. The data were collected from 2010 to 2013. First, patients’ and professionals’ perceptions of adherence management and restrictive factors of adherence were described (n = 61). Second, objectives and methods of the intervention were defined based on focus group interviews and previously used methods. Third, views of patients and professionals about barriers and requirements of the intervention were described (n = 61). Fourth, mHealth intervention was evaluated based on a literature review (n = 2) and patients preferences regarding the intervention (n = 562). Adherence management required support in everyday activities, social networks and maintaining a positive outlook. The factors restricting adherence were related to illness, behavior and the environment. The objective of the intervention was to support the intention to follow the treatment guidelines and recommendations with mHealth technology. The barriers and requirements for the use of the mHealth were related to technology, organizational issues and the users themselves. During the course of the intervention, 33 (6%) out of 562 participants wanted to edit the content, timing or amount of the mHealth tool, and 23 (4%) quit the intervention or study before its conclusion. According to the review, mHealth interventions were ineffective in promoting adherence. Prior to the intervention, participants perceived that adherence could be supported, and the use of mHealth as a part of treatment was seen as an acceptable and efficient method for doing so. In conclusion, the use of mHealth may be feasible among people with psychotic disorders. However, clear evidence for its effectiveness in regards to adherence is still currently inconclusive.

Automated UI testing. WBCT, a computer-automated user test environment tool.

Today, the user experience and usability in software application are becoming a major design issue due to the adaptation of many processes using new technologies. Therefore, the study of the user experience and usability might be included in every software development project and, thus, they should be tested to get traceable results. As a result of different testing methods to evaluate the concepts, a non-expert on the topic might have doubts on which option he/she should opt for and how to interpret the outcomes of the process. This work aims to create a process to ease the whole testing methodology based on the process created by Seffah et al. and a supporting software tool to follow the procedure of these testing methods for the user experience and usability.

User Experience Patterns for/of Innovation by Design: A Survey on Design Practices in the Software Development and Innovation Lifecycle

The User Experience (UX) designers are undoubtedly aware of how many UX design methods currently exist and that sometimes it becomes a problem to choose an appropriate one. What are all of methods that designers have in their “arsenal”? When can they use them? This thesis presents the research on the design methods in the contemporary context of User Experience (UX) and Innovations by using a survey approach. The study is limited to cover the domain of consumer mobile services development and provider companies around the world. The study follows 2 clear objectives: (1) to understand what design methods are currently used in that context and to what extent they are used (2) to identify at what stage according to the UX design thinking process for creating innovations they are placed. The study contributes to the research in the field of UX design and Innovations and extends the knowledge in that field together with communities’ (UXPA, SIGCHI, SIGSOFT) members’ cooperation. The research is vital due to lack of information on design practices and their application in the chosen context.

Standardized electrical tests for electrical equipment in road vehicles Case: Visedo Oy PowerMASTER M-frame

Electrical road vehicles were common at the begin of the 20th century but internal combustion engines took a victory from electrical motors in road vehicles. The acknowledgement of the environment, and the price and the availability of the crude oil are reasons for the comeback of the electrical vehicles. Advancement in industrial technology and political atmosphere in EU as the directive 20--20--20, which consists of reducing fossil emission, increasing renewable energy and increasing the energy efficiency, have made the electrification popular again. In this thesis tests based on standard ISO 16750--2 electrical loads for electrical equipment in road vehicles are made for Visedo Oy's PowerMASTER M-frame power electronics device. This device is designed for mainly drive trains in mobile work machines and marine vessels but can be used in other application in its power range which also includes road vehicles. The functionality of the device is tested with preliminary tests which act as a framework for the tests based on standards.

Virtuaalisen oppimisympäristön funktionaalisen käyttöliittymätestauksen automatisointi

Tämän tutkimuksen kohteena on Turun yliopistossa kehitetyn www-pohjaisen ViLLE-oppimisjärjestelmän funktionaalisen käyttöliittymätestauksen automatisointityö. Tutkimusta varten olen kerännyt kattavasti aineistoa aihetta käsittelevästä yleisestä kirjallisuudesta ja artikkeleista sekä toteutuksen kannalta spesifistä tietoa tarjoavista Internet-lähteistä. Tutkimuksessa olen tehnyt myös pienehkön määrän testausalan asiantuntijahaastatteluja. Tutkimuksen empiirisessä osuudessa olen valinnut testaukseen käytettävän testaustyökalun sekä toteuttanut valitulla testaustyökalulla ViLLE-oppimisjärjestelmän testauksen automatisointityön soveltamalla käytäntöön tutkimuksen teoriaosuudessa esitettyä tietoa hyvistä käytänteistä funktionaalisen käyttöliittymätestauksen automatisoinnissa. Tutkimuksen toteutuksessa olen käyttänyt kvalitatiivista tutkimusmenetelmää. Tutkimuksen empiirisen osuuden pohjalta kerätyn havaintoaineiston perusteella olen selvittänyt vastaukset seuraaviin tutkimuksessa esitettyihin tutkimuskysymyksiin: • Miten käytetty testaustyökalu on valittu ja mitkä olivat valintaan vaikuttaneet tärkeimmät kriteerit? • Miten käytetty testaustyökalu soveltuu ViLLE-oppimisjärjestelmän funktionaalisen käyttöliittymätestauksen automatisointiin? • Millä eri tavoin käytäntöön viety hyvien testiautomaation laatimistapojen mukainen toteutus vaikuttaa nyt laadittuun testiautomaatioon? • Esiintyikö toteutetussa testiautomaatiossa tutkimuksen teoreettisessa viitekehyksessä kuvattuja funktionaalisen käyttöliittymätestauksen automatisoinnille tyypillisiä ongelmia ja miten ongelmat saatiin ratkaistua? Tutkimuksen tulokset osoittavat melko selvästi, että ViLLE-oppimisympäristön funktionaalisen käyttöliittymätestauksen automatisointityön toteutukseen valittu Vaadin TestBench -testaustyökalu, joka on valittu tutkimuksen alkuvaiheessa suoritetun evaluoinnin perusteella, soveltuu käyttötarkoitukseensa hyvin. Lisäksi pystyin luotettavasti havainnoimaan, että testiautomaation ylläpidon tarve sekä testien laatimiseen kuluva aika vähenevät merkittävästi, kun testit laaditaan heti alusta lähtien rakenteeltaan modulaariseksi sekä tietyin teknisin keinoin mahdollisimman vähän käyttöliittymän rakennetta huomioonottavaksi. Ongelmia testiautomaation laatimisessa voivat aiheuttaa käytetty työkalu itsessään, testattavan järjestelmän toteutus sekä testien suoritusympäristö. Huolimatta kirjallisuuskatsauksen perusteella tehdystä varautumisesta tyypillisiin testiautomaation laatimisessa esiintyviin ongelmiin, myös joitakin sellaisia ongelmia esiintyi, joihin en ollut osannut varautua. Mahdollisiin ongelmiin etukäteen varautuminen kuitenkin selvästi auttoi suurimpaan osaan testiautomaation laatimisessa esiintyneistä ongelmista.
