The aim of our study is to deepen our understanding of how both social workers and clients describe how user influence within substance abuse care for adults can work. What difficul-ties do they describe meeting, with regards to possibilities to influence the care? To achieve our purpose we had a qualitative approach for this study. It?s based on open thematic inter-views with 3 clients who have substance abuse problems, and with 3 social workers, working at Social Services in Stockholm.

This thesis investigates how web agencys in Stockholm use, value and incoroprate the terms usability, user experience and interaction design in their work process. The purpose of this study is to investigate how creative professionals works with the notions of usability, user experience and interaction design with focus on the end user. Our definition of creative professionals is every employee at a web agency involved in the work process of developing digital artefacts in any capacity. We wanted to investigate how these notions are considered, consciously or unconsciously, during the workprocess. Semi-structured interviews were conducted at three different web agencys with eight different employees.

As organizations are generating more business intelligence in their systems, more employees need access those systems. As a result some sort of permission management needs to be implemented to ensure the information remain safe. Access Control Matrix (ACM) is one way of managing permissions and is widely used among organizations. The issues that comes with ACM is that the matrix itself gets difficult to manage and overview as its complexity increases with the number of permissions. The study utilizes Action Design Research to develop a tool for visualizing permissions.

På senare tid har smarta mobila enheter fått en allt större roll i vardagen och det finns en uppsjö av applikationer till dessa. Den som är uppmärksam kan upptäcka att prestandan och användarupplevelsen kan variera kraftigt mellan olika applikationer. Prestandaoptimering är en viktig del i utvecklingsprocessen för mobila applikationer eftersom mobila enheter ofta har betydligt mer begränsade resurser jämfört med till exempel persondatorer. Eftersom prestanda är komplext med många faktorer som spelar in kan man använda sig av verktyg för att underlätta optimeringsarbetet. För att hitta de mest lämpliga verktygen för prestandaoptimering av Android-applikationer har en utvärdering av en delmängd verktyg som finns på marknaden utförts.

The aim of this Master's thesis is to examine what effect two different models of acquisition have on user satisfaction with information resources at academic libraries. The two models examined are the traditional model where a subject specialist librarian makes the selection, and the user-governed model where the larger part of the selection is based on user requests. The scope is the libraries of Roskilde University, which employs the traditional acquisition model and Malmö University, which employs the user-governed. Both libraries have a user-oriented approach to acquisition. The study encompasses a close examination of the acquisition policy through document analysis and interviews with the librarians in charge of acquisitions at each university, as well as a user-satisfaction survey among the professors and senior teachers on two faculties at each university respectively.

Detta examensarbete utfördes hos företaget Syntronic i mjärdevi. Uppgiften de ville ha utförd var en undersökning och implementation av ny funktionalitet i en redan existerande android applikation som de har utvecklat. Uppgiften i denna applikation var att undersöka möjligheterna till IP-telefoni, eller VOIP som det kallas, så att de kunde ringa varandra via applikationen genom datanätet istället för det ordinära nätet, samt att implementera detta.Detta examensarbete utfördes hos företaget Syntronic i mjärdevi.

This thesis has been performed for the company System Andersson as a part of the bachelors degree in information technology at the School of Engineering in Jönköping. The thesis is based on the development of an iPhone application.System Andersson has an application for Android that is being used for their MPS system (material and production control system). Their customers, however, have also showed interest in being able to use this application for iPhone.The students handle the subject of iOS developing, including the design of the application, the use of the development language Objective-C, the use of the scripting language of Json used for server connections and SQL.The primary goal with this thesis has been to improve the students knowledge in such subjects as application development for mobile platforms, in such areas as Xcode, which is the development platform that Apple uses and Objective-C, which is the development language being used. The result of this thesis is an almost fully functional iOS application, similar to the Android application with some functionality missing..

The most predominant method for forest harvesting in Sweden is the cut-to-length method based on two-machines, a harvester that fells trees and cut them in a predefined length, and a forwarder which transports logs to a landing area for further transport to a processing facility. New machine solutions have to be much gentler to the ground than today?s machines. To be able to develop a forestry machine that preserves the terrain requires a proper understanding of the interaction between tire and soil.The goal of the project is to contribute to the existing knowledge of forest machine tire-soil interaction and to develop a tire-soil model that enables dynamic simulations of forest machines operating in rough terrain. The modeling has especially been focused on the interaction between tires and soft ground.A comparison of theoretical data of different WES-based terrain interaction models and a comparison test data from a full scale field test is presented.

This study investigates augmented reality using third person perspective and what precision can be achieved by using this method. There have been prior studies in regards to precision using augmented reality, however studies using third person perspective is scarce. This study presents a solution using a static camera capturing the user as well as the plane to augment from behind. This augmented image is then transferred to a handheld device that is held by the user. Using this method the user will be free to manipulate and work with the plane without removing the device that captures the scene, a common problem when using visual reference markers in augmented reality.

The aim of this thesis is to study a number of standards and theories, from the two research areas human-computer interaction and psychology, about how a graphical user interface (GUI) should be composed in order to facilitate interaction between humans and computers. Special emphasis is put on how the GUI should take into consideration the strengths and limitations of human cognition and perception. A study of three web catalogues shows how these theories appear when concretised. The following questions are answered in this thesis:What guidelines and styleguides can be found that specify the design of a user-friendly GUI?How do a few library catalogues on the web match a selection of these design principles?The guidelines are extracted from literature concerning human-computer interaction, psychology, automated library systems and web design.

Grafiska dokumentgränssnitt används av de flesta datoranvändare. Det finns i huvudsak tre typer av dokumentgränssnitt; MDI (multiple document interface), SDI (single document interface) och TDI (tabbed document interface). I ena halvan av arbetet har dessa tre analyserats utifrån en rad faktorer med målet att se om någon modells fördelar väger över de andras och om man kan skapa några riktlinjer för när det är bäst att applicera respektive modell när man utvecklar en ny programvara. Analysen är baserad på litteratur samt kvalitativ enkätundersökning och programtest. Andra delen av arbetet har ägnats åt testa om det går att programmera så att slutanvändaren kan välja den modell han eller hon föredrar.

This essay is an investigation of the level- and importance of interactivity on YouTube for the active user. YouTube is a great example of a user-friendly Internet environment which enables the users to take part in a virtual community where they can create the content and, with the various functions the site has to offer, interact with each other. With Uses and Gratifications as a tool for this research we look at the motivations and needs of the user and how they come into play on the most popular video distribution site in the world today. Qualitative interviews on Swedish respondents give us insight in how the YouTube-users with their own words perceive this relatively new highly interactive era. We focus on a narrow group of the most popular age-group of YouTube-users to go deeper - not to expand.

User-centred acquisitions at three academic librariesA new way of developing collections has been adopted at a number of small academic libraries, user-centred acquisitions. The method implies that the main way of building the collection is by means of receiving suggestions of titles from library users. The main purpose of this thesis is to investigate changes in acquisitions of monographs. At a more detailed level it seeks a deeper understanding of what user-centred acquisitions is and how the method effects the acquisitions process. Changes in stock management and the reason why the libraries have chosen the method is investigated as well.

Within system development users have rarely been involved or received much attention during the development. Most of the times, the primary focus within system development lies on insuring functionality, rather than making the system usable. The literature specifies that a non user-centered approach can contribute to a product with low usability, which can lead to an ineffective and unsatisfactory experience for the end users.The purpose of this thesis is to begin an investigation to see if the use of non user-oriented system development methods is a possible cause of low usability in the final system.To achieve the purpose of this thesis, we have conducted a case study. Within the case study we examined the usability of a time reporting system. The case study included seven minor studies; an investigation concerning the development of the system, an expert evaluation of the system, interviews and observations of users, developed paper prototypes and executable prototypes, both which user testing was performed on.The result of this study shows that by working with user-entered methods, the usability in the time reporting system increased after the design had been revised.

Kriminalvården är den myndighet i Sverige som ansvarar för fängelser, häkten och frivård. Myndigheten har länge känt ett behov att inom flera verksamheter kunna få tillgång till delmängder av deras klientsystem i ett mobilt och uppkopplat format.Det största hindret i deras fall med mobilitet och applikationsteknik var säkerheten. Därför genomfördes en riskanalys med hänsyn till frivården och mobilapplikationsteknik.För att välja en lämplig och passande riskanalysmetod jämförde vi ett antal metoder. Det visade sig att metoden CORAS passade bäst. När vi väl genomfört riskanalysen med CORAS försökte vi sedan matcha åtgärderna mot de olika mobilplattformarnas egenskaper för att se hur de kan fullfölja åtgärderna.
