The object of this study is to examine the effective functionality of an OPAC-system while a few participants interacted with the catalogue. I?ve used Carl Martin Allwood?s (1998) four designed usability factors to be able to estimate the effective functionality of the online catalogue. Theoretic basis is Human Computer Interaction together with Allwood?s four defined usability factors.

The purpose of this study was to follow a research-oriented design process and to develop a design draft for a digital service that supports users to make more environmentally conscious choises in their everyday life. By following an interaction design process from start to final delivery, the study aims at creating a broad understanding of the process. Therefore, many userrelated activities were implemented in the study: eg. personas, scenarios, sketching and user testing. The project resulted in digital wireframes for an iPhone application using embedded GPS to identify and locate environmentally friendly businesses.

The aim of this thesis is to define digital library, and to investigate a relation between the construction of a digital library and user needs. The main questions to be answered are: 1 What criteria was used when constructing a digital library, particularly concerning issues like purpose, function, design, supply, services, resources and future development of the digital library? 2 How do the digital library system designers and system builders criteria correspond with those of postgraduate researchers? And what factors affect the use? A digital library is an enterprise that gives access to information stored digitally and directly available on the net. The crucial is that the enterprise has a control over collection of information and responsibility to make it available to a defined group of users. In order to investigate the relation between the construction of the digital library and user needs, I have interviewed five key people involved with the work with the digital library and twenty postgraduate researchers from the Gothenburg University.

This report describes the process of developing a user-friendly and responsive archive website. The website is a Hi-fi prototype and was created for the company JG Communications, to serve as an archive for their customers? style guidelines. To create this website I have used HTML5 and CSS3 to make it responsive for various computer screens. I have also used PHP and some JavaScript to make some of the functions and Adobe Photoshop and Illustrator to make design elements for the prototype.

In order to understand user behaviour and navigation patterns, user logging is today widely used in analysis and development of user interfaces. These user logs tend to be quite many and can contain a lot of different data. A big issue is how to process and display this data in a perspicuous way to the stakeholder. This study is about how to develop a prototype to handle this issue. It was solved by various methods from human-computer interaction.

The aim of this essay is to examine three separate Swedish public libraries and their respective websites on the grounds of the usability sciences. I firstly had to summarize the main properties of the usability-field in order to gain an extended knowledge of its purposes and possible usage for today?s library systems. I was then able to apply the extended knowledge in the examination of the three library websites and the purpose of determining whether or not they were designed according to the standards set by the usability-sciences.Usability is a rather new science that deals with the dissection and examination of computer-based systems, in order to find the key components that make systems user-friendlier. With user needs being the main focus of its research, usability tries to meet all the different needs of the modern user and construct systems that are less system-centered and more user-centered.

The purpose of this Masters thesis is to investigate the role of link collections in Swedish public libraries mediation of Internet resources. The study is focusing on the effects on the contents and the structure in the link collections when the target group is immigrant users. This is done through literature studies completed with an examination of two link collections containing multi-cultural and multi-lingual material and qualitative interviews with the two librarians who are in charge of the collections. The major questions raised in this study are: What function do the link collections have for the public libraries? What is the difference in working with traditional, printed material compared to the work with Internet resources? And how are the selection of Internet resources and the structure of the link collections affected when the collection is intended for immigrant users? The main results are that link collections in public libraries can give a concrete form to political guidelines.

Abstract: After their introduction, technical systems designed for Situational Awareness have changed the possibilities on the battlefield. Today, Swedish tanks use a system known as the TCCS. This system offers many advantages to a tank platoon, but does it also bring disadvantages? This essay examines pros and cons with the TCCS. To find these the author uses a Swedish Armed Forces analyze model in a comparative study.

Our aim in this work has been to redesign ModernFamilies and make a user-friendly interface for people with aphasia. The focus has been to identify general issues they might face while using different technology and applications, in order to find better alternative design for ModernFamilies, with a focus on usability. To approach this issue, we used a qualitative method. Our study includes several interviews and observations preformed in conjunction with the AGNES project (AGeing in a NEtworked Society) and speech therapists. Aphasia requires simple design that in the same time gives them support to understand and use technology and different applications.

The purpose of this Masters thesis has been to study the changes made in shelf arrangement and library environment in a Swedish public library. The aim was to examine the reasoning done by the library staff regarding classification, the Swedish classification system SAB and changes in library environment. The basis of our study were three questions: 1. Why has Västervik public library made changes in the shelf arrangement? 2.

It becomes increasingly more difficult to stand out among the personal sites on the internet today and to become the one who actually gets remembered in the crowd. To be remembered, you need to have a useful website but also a creative appearance added to it.In this practical thesis I have focused on how a website should look like according to users and then added a creative look to the user-friendly website. The purpose of the study is to find out how to connect a useful website with a creative appearance. In order to do that, I first had to find out what users actually want. I used a survey in which I have asked questions about how a website should look like.

The consultancy firm Knowit sought a smartphone application for communication between schools and pupils. Together with the students, it was decided to create the app both for Android and for iPhone. The project would produce a prototype app with limited functionality usable as a proof-of-concept in communication with potential customers.The questions that have characterized the work are; what features would be demanded in a school app, how to program user-friendly functionality and how to use object-orientation to design such an app. A question has also mentioned the differences between development for iOS and Android. The work was done in an iterative process in which the students worked together with planning, programming and testing.

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.
