Denna rapport handlar om en användbarhetsutvärdering av synthesizern OP-1, utvecklad av företaget Teenage Engineering. Studien är kvalitativ och undersöker bara den omedelbara användarupplevelsen av produkten. Rapporten baseras på resultat från ett antal användbarhetstester, utförda på företaget i fråga. Användbarhetstesterna avser att undersöka hur en användare kan förstå hur OP-1:s kan användas och hur de kan förstår dess olika lägen och vidare på vilket sätt detta påverkar den initiala användarupplevelsen.Totalt nio av fjorton tillfrågade personer har ingått i användbarhetstesterna. Urvalsgruppen bestod av personer med tidigare, dock varierande mängd, erfarenhet av synthesizers.

User friendly and usable are two words that are often mentioned in the context of marketing new products. By doing so it adds an extra sense of quality to the product. The meaning of these words is therefore something that every product wants. But what is it that makes a product usable and user friendly? What methodology exists formaking sure that a product is usable? Does it exist applicable processes to ensure user centered development? These questions together with a practical example are parts of what will be addressed in this report.The thesis was carried out for C2 Management, a company that works with supporting other companies in their work with quality and constant improvements.

Thermal fatigue is a serious problem in todays power plants. A large amount of damages around the world circles around that subject. The damage can come from the mechanism of two flows mixing with different temperatures in a T-junction. It is a fundamental prerequisite that these T-junctions are frequently tested for damages. An amount of criterias steers the rate of testings.

This report presents the development process of a mobile interface for the C2-monitor. A monitoring tool used to support the operations for the broadcasting services of Ericsson Broadcasting and Media Services (EBMS). With the support of the C2-monitor, operators can monitor hundreds of channels and services produced from EBMS. To enhance a more flexible working environment, the C2-monitor needs to be developed further to support mobile devices with a customized design to take advantage of mobile phones features and functionality. Established and well-recognized design methods and principles have been applied in the development process and user testing have been made iteratively throughout the project.

This report presents a master thesis project performed at Elekta AB during the fall of 2013 and early 2014. Elekta is a medical technology company and their main product in the Stockholm office is a gamma knife used for radiosurgery. The gamma knife contains a cluster of a dozen motor servos and motors used for adjusting the patient and the radiation sources over a CAN bus. A self-developed hardware-in-loop simulator running on a PC with LabVIEW is currently being used for integration level testing of the control system of the gamma knife. The simulator has some problems with it not running in real-time and having other performance issues.

In today?s IT world where software is constructed in a rapid pace, testing has become a crucial area to master when testing has to be done at a greater speed. To still be able to handle the demands of high quality software, companies have to spend more resources on testing and introduce test automation. By automating test cases the testers can gain time which they can spend on doing more complex testing and thereby increase the quality of the software.In this thesis we have helped Extenda AB, who delivers systems to retail companies, to introduce test automation in one of their customer specific projects. This has been done using their own in-house ?capture/replay? tool ECP (Extenda Cashier Player).We have also derived a process that explains how Extenda can introduce test automation on other customer projects.

This paper works as an assignment from the Video On Demand Company Headweb, who wanted aninterface analysis of their own and their competitors VOD services. The purpose is to help Headwebwith their own interface by studying theirs and others interfaces and make an analysis on how theyfunction, how they look and how good the usability is with every service, with hope to findsomething that could make the VOD service of Headweb better.I have also studied how the interfaces of the VOD services look on different platforms, to see howthey are designed as a whole. This has been an expert analysis where I have studied the differentVOD-services by myself, without any external users.To find advantages and disadvantages with the services and their platforms, I have used differenttheories, models and design patterns to frame areas such as filmsearch, categorization, registrationand navigation. I have compared the VOD services with each other and drew conclusions for eacharea to see how the interfaces differ between the services, but also between platforms.My analysis has shown that all VOD services in this project have a very unique interface, eventhough they all have the same goal, to allow the user to control their viewing of film. They usevarious functions and structure and use their own page names and categorizations.

ABB and Prevas have initiated a collaboration to sell a system to optimize steel industry furnaces, called FOCS. The purpose of this thesis is to investigate possibilities for integrating Prevas FOCS and ABB 800xA.The result of the investigation is used for an implementation of a prototype of the integrated system. The study shows a general method that can be used when implementing two software systems. The prototype of the integrated systems is made with usability principles in mind. This is a very important aspect in order to create a good working environment for the operators of a steel plant.

The City Library has a problem getting children interested in reading. Futhermore, there are no clear signs to aid children to navigate themselves to books targeted to their age group. To solve this problem, this thesis aims to design signs that is both illustrative and informative.Of the images that were tested during the research, I would assume that children in such a wide age range requires the simplest level of abstraction from testing the three testing icons, since the second level of abstraction was not interesting enough for the kids. The third, nearphotorealistic level was most liked by the children who were in the city library more often and looked for books themselves..

The communication with government and municipality through Internet has in-creased during the last couple of years. Therefore we have chosen to focus our bachelor thesis in this particularly area and the needs for usable web services for the citizens. In this bachelor thesis we are studying a increasing group users, namely elderly citizens. During the study we have analysed E-governments ser-vices usability through usability tests. The combination of conversations and meetings with individuals, observations of interactions and literature studies give us the opportunity to explore the users needs.

This report describes how the process has evolved during the creation of a new web page forthe company Scandinavian Travel Agent DMC.

The aim of this study is to examine the patient's understanding of the counselling while testing for an STI. The method was an inquiry directed to patients at two receptions, where tests for STI are made, and on the Internet for patients who made a test within the last year. The study involves 95 participants, 39 answered the inquiry directly after the test. The main results show that most participants are positive to talk about their sexuality and sexual strategies with the personnel, irrespective of who takes the initiative to the counselling. Women are yet more negative then men to talk about their sexuality, even if the test is made voluntarily by the woman.

This aim of this thesis is to measure the effect of the user interface in real searches on the Internet through a small experiment. Theories on web and search usability and psychological factors concerning usability were first explored. Then three interfaces were constructed, one "good" that followed usability guidelines and had multiple search functions, one "bad" that completely disobeyed those guidelines and had only a simple and small search field, and one "intermediate" interface that was a mix of the two. The search field was set to different sizes, with the shortest in the "bad" interface, a medium field in the "intermediate" interface and several long fields in the "good" interface. All three interfaces were then attached to the same web search engine, Altavista.

In order to increase the independence in everyday life of the elderly population, we have developed a lifting aid for loading in the private car trunk. Independence from outside assistance affects self-esteem in a positive direction and can help increase the quality of life for a large group of individuals. As people age and experience changes in performance, it is important that aids and support is available, particularly to reduce the experience of aging and it?s increasing physical limitations. The aim was to develop a function prototype characterized by simplicity, which facilitates loading of the private cartrunk.The project was conducted at the request of Autoadapt AB, which is one of the leadingactors in car adaptations for individuals with disablilities.
