The aim of this thesis is to accomplish a user study on how e-book users experience the electronic book, the e-book, as an instrument for reading fiction. The study is based upon qualitative interviews with twelve e-book users and a small survey carried out at the Stockholm City Library. The purpose is to identify the users' incentive for choosing the e-book as a medium for reading fiction, elucidate if and how the interface of the e-book affects the reading experience, and distinguish if there are any factors common to the users in their choice of reading e-books. How the users look upon the future of the e-book is also discussed. Among the people asked in the survey we note little if any demand for the e-book as an instrument for reading fiction.

The following report documents the development process of that upgrade ascarried out by the author. The project draws on research in usability design and cognitivepsychology to develop a user-friendly interface.

This thesis was developed as an assignment from Ludosity Interactive where the goal was to develop a copy of the Xbox Live Indie Games-marketplace from the Xbox 360. Ludosity Interactive had a necessity to easily test a game's attractiveness to potential customers using testing people from outside the company in a simulated Xbox Live Indie Games test environment; excluding this developed system there is no other way to do such an analysis without actually releasing the game on the Xbox Live Indie Games marketplace and then analyze the resulting sales from the product.The finished system had to be similar to the original system to the degree that a user could see past the interface itself and use the system just as he/she would have used the real marketplace. It also had to be easy to change and add games to the system so that Ludosity Interactive easily could show the games and the data that they deemed interesting for their tests. The final product was developed using C#, XNA and XML together with an Agileinspired development method in combination with Pivotal Tracker. This report describes how this product was developed..

A degree project has been carried out at Motion Control, Västerås. The degreeproject ?Grafisk Skärm för Inbyggda System? have developed a first prototype of anembedded system with a display, a graphical user interface with touchscreen andpossibilities to communicate with external units.The work initiated with surveys of critical components. A technical specification forthe desired end product was developed. With the technical specification as support,design specifications for hardware and firmware were developed.After the specifications were done, a circuit diagram was developed and a circuitboard was made.

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.

This thesis contains a usability evaluation of ?Barnplay?, a Swedish video-on-demand service targeted at children. The objective of the study was to identify usability issues in the video service and to develop measures on improving the user interface, with special focus on adaptation to the broad target group of 3-11 year olds.The study was conducted by first mapping established practices in designs of VOD-services targeted at children, followed by interviews and usability tests with children between 2-11 concerning their use of ?Barnplay?. Based on the initial data collection, a prototype was developed and then evaluated by usability testing and A/B-testing.The main conclusion of the study is the need of better individual adjustment of the video content selection to better appeal to different age segments within the target group.

Chalmers University of Technology today have numerous computers which are never powereddown, at the same time there is a need for more computation power for researchers.Hence, we have investigated the possibility to use the computers for computing power andsecondly, if there is no work to be done, to put them into power saving mode.We have made a thorough study where we compared different distributing systems andin the end HTCondor was chosen as the best to implement. HTCondor is an excellent systemfor opportunistic use of computing power, i.e. make use of computers that no one elseis currently using. The system is used at several universities around the world with goodresults and would be excellent at Chalmers, where there is a need for such a system.Our implementation shows that HTCondor is well capable of handling unused computingpower. HTCondor can handle most file types that may be run on the system.

The use of mobile devices has increased dramatically in recent years and the development of newtechnologies has made it difficult for developers to know what screen size and device the visitor isusing. This has resulted in the fact that today there is a problem with the interface for web pages onmobile devices. They are not adapted to the flexibility required for the interfaces to be recognizedon various mobile devices. Instead of developing two separate web pages, where one is designed formobile devices and one for desktop and keep them both continously updated, responsive webdesign simplifies the work process. Responsive web design is a flexible and dynamic interface thatadapts to mobile device and screen sizes.

Jag kommer i denna uppsats beskriva den designprocess som pågått vid skapandet av en webbaserad informationsplattform från koncept till slutprodukt.Mitt uppdrag har varit att effektivisera en webbyrås nuvarande sätt att hantera och sprida information på, som bestod av en blandning mellan digital och analog information, och skapa en ny webbaserad informationsplattform. Den nya webbaserade informationsplattformen ska kunna samla all information på en plats och skapa ett effektivare informationsutbyte mellan de anställda på företaget.Jag har använt mig av två teoretiska ramverk; Nielsens tio heuristics samt Krugs visuella design hierarki.Jag har arbetat nära beställaren för att kunna skräddarsy webbplatsen till deras behov.Resultatet efter ett omfattande arbete med designmallar och front-end kodning blev grunden för webbyråns webbaserade informationsplattform, utvecklad för att effektivisera spridningen av information på företaget..

Syftet med uppsatsen är att undersöka om Feldenkrais-metoden kan vara till hjälp i sångutövande, och hur man kan använda Feldenkrais-metoden i sångundervisning. Jag har valt att använda mig av en kvalitativ undersökning där jag utgått från litteratur, en intervju samt deltagande observation ur ett emiskt/etiskt perspektiv. Som sångare eller utövare av något musikaliskt instrument är det av stor vikt att man är medveten om, och tar hand om sin kropp, för att kunna prestera på topp och hålla i längden. Feldenkrais metoden kan i detta fall fungera som en nyckel till att finna lätthet i rörelse och andning. Man bör dock belysa att det finns många andra metoder att nå kroppsligt välbefinnande på, och att det är upp till individen att känna vad som passar bäst.The aim of this thesis is to examine if the Feldenkrais- method can be of help in singing practise, and how you can use the method in voice teaching.

Tankarna som har lett till den här uppsatsen är sprungna ur många långa och sena datorspelsessioner över internet. Man kunde ana att personer pratade olika beroende på om de var tvungna att trycka ner en knapp (Push-To-Talk) när de pratade med varandra eller om de bara kunde tala rakt ut (Voice Activation/Activated). För att undersöka frågeställningarna valdes en kvalitativ metod inspirerad av Hutchins tankar på hur kognition bör studeras i dess naturliga kontext (?cognition in the wild") realistisk soldatsimulator och undersökningsdeltagarna rekryterades från ett community som ofta spelar sagda spel. På så sätt eftersträvades det att studien genomfördes i sin ?vilda? kontext där röstchattandet blir en kombination av uppstyrt problemlösande och socialt småprat.

This report is the result of a diploma work made at IMT at US in Linköping. The purpose of this piece of work is to investigate the possibility to design a general program for data-acquisition using LabVIEW, suiting different hardwares and connections. Great importance has been attached to communication with serialport, using bluetooth, because different wireless PPG-instruments has been developed parallel to this project. These PPG-circuits uses this type of serialcommunication. Communication with USB, GPIB and analog connection has also been examined and analog communication has been tested practically.

The main objective of this thesis was to develop appropriate strategies and find factors that affect the usability of parameterized designs. This was accomplished by investigate the user-interface and how it is designed to meet the user's information needs. The thesis also embraces the basic theories in terms of investigation, cognitive design principles and human behavior patterns in the interaction with the machine. The approach has led to an explorative investigation in this subject area.The thesis also had the purpose to achieve more efficient ways for development of motor chainsaws at Husqvarna AB's department Global Cutting Equipment. That can be achieved through reduce costs of development per sold unit.

This essay is a survey of thirteen user studies performed in the field of image retrieval. The purpose is to try to distinguish principles that should be kept in mind when wanting to make image databases available for a wide and varied group of users. The essay tries to answer two questions, namely: Are there any results in accordance among the different studies? What in the user studies should be considered when it comes to how content description, interface and functions for searching can be designed when creating systems for image retrieval? Each study is first reviewed on its own, and then a comparative analysis of all the studies is carried out. Derived from the result of this analysis, the conclusion is presented in the form of a row of suggestions to which aspects are to be suitably included in the design of image databases.
