Den här rapporten behandlar frågeställningen om hur man kan anpassa systemutvecklingav ett informationssystem enligt livscykelmodellen till att inkludera användbarhetstester. Frågeställningen grundar sig i att god användbarhet inte är ett explicit uttryckt mål i Andersens beskrivning av livscykelmodellen. För att besvara frågeställningen har vi utvecklat och testat ett bokningssystem åt en mindre verksamhet. Utvecklingsarbetet har bedrivits enligt en egen anpassning av livscykelmodellen. Testerna har utförts enligt metoden cooperativ evaluation.

The project, Flexible Snowboard System, has been carried out by the project group independently and is a module developed for snowboarders, ski rentals and ski schools. The problems of today?s solutions are that they cause the user an inconvenient standing position when riding the ski lift or skating the transportation slope, also mounting, adjustments and disassembling of the bindings are time consuming and brings undesired wear to the screws and screw holes. In addition any adjustments require that the user steps out of the bindings and have tools at hand. Flexible Snowboard System is a universal module which means that it can be assembled with all of today?s snowboards and bindings.

Denna rapport syftar till att beskriva arbetet med att utveckla en prototyp till den nya versionen av Hmi Designer utvecklat av Bombardier Transportation. Detta designerverktyg används för att skapa det grafiska användargränssnittet på ett tågs kontrolldator. En ny version av designverktyget är nödvändig eftersom resterande delar av Bombardiers programpaket för utveckling av applikationer har bytt både programmeringsmiljö och programmeringsspråk. Den prototyp som utvecklades ska visa på möjligheterna att i ett senare skede utföra ett fullskaligt projekt. Prototypen implementeras som en insticksmodul till Qt Creator, därav beskrivs tillvägagångssättet för att utveckla insticksmoduler i den programmeringsmiljön samt de fördelar och nackdelar som identifierats i och med ett byte till Qt Creator.

In recent years, employees at large companies have started to demand that their employer should work more for good causes. The money the company wants to donate to charity is distributed mostly through a vote to decide where the money will be remitted. The purpose of this design case is to develop a design concept for a web-based donation service that involves all employees at a company. Furthermore, the authors of this study intends to explore how the motivation for employees of a company can be affected by participation in this service. In this design case, the service function, quality and concept was tested and evaluated.

Studiens syfte var att undersöka möjligheterna att använda intervjutekniken Repertory Grid Technique (RGT) som utvärderingsteknik för att utvärdera User Experience (UX) på distans. Detta gjordes genom att de föreställningar som en handledarstödd utvärdering resulterade i jämfördes med det resultat som uppnåddes genom en webbaserad variant av samma utvärdering. Studiens resultat visade på en svårighet för respondenterna i den webbaserade utvärderingen att formulera föreställningar som går att använda för analys av en produkts UX. Diskussionen pekar på en tänkbar lösning i form av förstudier som utförs med en mindre grupp av respondenter för att på detta sätt hjälpa utvärderarna att skapa sig en referensram att använda vid tolkningen av de föreställningar som sedan kan samlas in under en webbaserad utvärdering. Studien syftade även till att jämföra vilka aspekter kopplade till UX som utvärderingarna genererade, samtliga av dessa kopplades till subjektiva eller produktrelaterade aspekter..

The tick-borne disease bovine anaplasmosis is primarily caused by Anaplasma marginale. A variety of wild animals act as reservoirs for A. marginale, but the understanding of their role in the epidemiology of A. marginale is yet poor. This cross-sectional study was conducted to establish if proximity of wildlife affect the prevalence of bovine anaplasmosis in cattle.

For a long period of time there have been discussions about the need to modernize, to keep up with the changes in our society. The schools as a result have to keep up and adapt in order for the education to be up-to-date. This includes the technological developments. Many steps have been taken and mighty sums have been invested in order to keep up the pace ? but are there any consequences from these kinds of investments? In this report I?m going to take a closer look on a recent addition to this phenomenon that were installed by means of a top-down approach and study the teachers and how they have adapted and view the change in their environment ? namely the newly installed interactive writing-boards.The questions I will study include how the teachers express their view about the installation of the interactive writing-boards.

Collaborative music making on the Internet is not a new phenomenon, but no applications have yet caught on with the vast number of laptop and bedroom studio musicians active today. This is strange considering the inherent social and interactive nature of music, especially amongst trends like Web 2.0 where collaboration and user-generated data is key. In this paper I study the problems these applications face, and why they do not have a greater appeal to musicians. With the results I develop and evaluate my own framework, known as Crescendo Online: a multi-user sequencing and modular synthesis environment, intended to pave the way for a new type of online music creation platform..

This study examined how users interact with a smartphone while in a learning situation based on videos via smartphones as a learning tool, and how this interaction and phenomena is experienced. The five test subject were separately given the same task that they were to solve using video instructions that were picked out and given to them. After finishing the task the subjects were observed while they demonstrated how they completed the task. After the observation the subject were interviewed using semi-structured interviews. The results show that the user experience of this phenomena is based on more pragmatic values than we could find in earlier studies, i.e.

This study has researched how user click heatmaps and eye tracking can be utilized in usability testing. We have used the tools SessionCam and Tobii. We designed a website for a small clothing store and conducted usability tests, in order to evaluate the users clicks and eye movements in relation to design choices on the website. The aim of this study was to research how these tools can be integrated in usability testing and how results from the tests can be used to improve usability. We were able to use the recordings of clicks and eye movements and make design changes based on the findings.

Today's technology offers a variety of opportunities to interact with the interactive systems. Human-Computer Interaction in the last decade is the area of research that has contributed the most to this development. But how is this interaction perceived? The user experience is something that is formed by the interaction between human and the computer interactive systems. The objective of this thesis is to investigate how the user experience differs depending on how one interacts with a game.

The purpose of this Master?s thesis is to investigate how academic librarians experience reference work aimed at international students. International students are a growing usergroup in Swedish academic libraries. The study?s main research question is:- How do academic librarians experience reference work aimed at international students?The study was performed with a phenomenographic methodological approach where seven qualitative interviews with academic librarians were conducted.

The project was carried out in cooperation with the department of product development IOS at IKEA. The work included improvements of a new existing product that Ikea soon will release on the market, Observatör, a wall bracket for flat screens. The product is supposed to fulfil the needs within this market for IKEA. However, since Ikea was not satisfied with it, our work was to carry out the improvements that were specified in the beginning of the project. Another task in the project was to develop a side-product that is supposed to be used together with Obeservatör for storage of DVD/decoders.The project included labour as problem definition to final technical drawings and a prototype.

Minimizing power consumption is a critical part of many embedded design projects. Thechallenge is to limit the power consumption of the system and at the same time providesatisfactory service to the user. With regards to microprocessors, the main way of limiting powerconsumption during program execution is to adjust the frequency and the voltage at which theprocessor operates.To enable the implementation of real-time scheduling with support for dynamic voltage andfrequency scaling, an exhaustive study of the Freescale i.MX31 embedded microprocessor isperformed. Specifically, the power consumption relationship to all relevant frequency andvoltage settings is investigated. In addition, to enable frequency and voltage scaling in a real-timeenvironment, a complete timing analysis of proposed voltage and frequency scaling methods isperformed and their suitability for use in real-time systems is evaluated.To integrate voltage and frequency scaling capability into OSE RTOS, a software module hasbeen developed for this operating system.

Contemporary plant design can be examined by how it relates to two extremes - Nature and Art. This idea is explained by Noel Kingsbury in the book The Dynamic Landscape where he places designers and their projects on a gradient (Kingsbury, 2004). Nature, one of the extremes can be represented by a dynamic, species-rich plant design with native species and with nature as the ideal. The other extreme - Art implies a more static view on plant design. Here, the designs consist of colourful flowers, exotic species and cultivars with double flowers.
