The client of the project was Medilink AB located in Lindesberg, and the contact person was Nils-Erik Söderström, Chief Executive Officer. The project was supervised by lecturer, Lennart Wihk, and examined by lecturer and professor Fredrik Thuvander at Karlstad University.

The company Sound Precision has developed a new Line Array loudspeaker system (VHA-40). When using this system, their customers need computer aid to get the best possible sound-quality and control of sound levels for the whole audience. The aim of this thesis is to develop a truly useful sound quality simulator for the VHA-40. The system will help the sound engineers to position the loudspeakers for optimal sound by simulating loudspeaker configurations and visualizing the resulting sound quality and quantity. To solve this a human-centered design (HCD) approach is taken to implement a system that is truly useful for the users, meaning that they will use it more and hence deliver better sound for the audience.

This essay deals with the subject of communication through Facebook. In this survey we studied 100 youths from Karlstad and their communication habits and behavior patterns on Facebook. The social network site Facebook has since its start in 2004 made a mark in modern communication. Today in 2010 the site has more than 500 million users. This paper wants to study what happens to other types of communication.

The report aims to investigate how well a certain type of affordable embedded single board computer can hold up against today's more expensive computers in a computer system by doing various tests on a system with the specified requirements. The system has a Raspberry Pi as the single board computer which task is to control a camera based on coordinates obtained from a server as well as capture and stream a video signal on a network.The researches were conducted to check how much network traffic a single-chip computer sent in different video formats and how much CPU utilization was required. Studies were also made to ensure the accuracy of the camera control. The researches have been experimental, where several tests have been performed and analyzed.The results show that a sufficiently good accuracy can be obtained from the camera steering unit, in which two different servos have been investigated. When the video format MJPEG and H.264 are used, the single-chip computer is able to transmit a video signal up to 1280x720 at 15 fps.

Today we can create digital 3D models which can be realised almost instantly through production methods such as 3D printing and computer controlled milling.What if this same technology could be applied to the development and construction of terrain parks?With snow as the material tools could be developed using similar principles to design and sculpt the surface, only on a larger scale.How would terrain park designers adapt their process to use this new technology? In this Industrial design thesis I explore how the ideas of the terrain park designer can be expressed through such a system with focus on the designers knowledge and skill without the need to learn complicated 3D programs.Sketch, create, ride. .

This thesis examines which function the information technology may have in thechildren's library, with the example from two library computer programmes. One is anexpert system, Hedvig, which will help children to choose and to find books, and theother is a computer game, The mysterious signs, that will teach children library user education.The main question is: What conceptions do the project-leaders, the children'slibrarians and the children have concerning the function of these two programmes in thechildren's library?The study is based upon qualitative interviews with two projects-leaders, fourlibrarians, three computer programmers and twenty-eight children.The theoretical material consists of examples on other library computer programmesfor children developed in Denmark and USA, some American studies in children'sabilities to use computerized information retrieval systems, and studies concerningchildren's relations to computers.The adult's conceptions of the computer programmes are divided into categories asfollows: Democracy, aspect of sex, complement, marketing, reading promotion,development of competence, information technology development, pedagogics, adulteducational activities, compensation and armusement, pedagogics, usefulness,effectiveness and information. These categories shall be seen as the conclusions of the thesis..

A LED spectrometer has been constructed for qualitative spectrometry using certain wavelenghts. The LEDs and the photodiode are being controlled with a microcontroller that is connected to a computer to power the components and save data. The spectroanalysis made with the LED spectrometer were significantly different to a standard spectrometer, concluding that more analysis should be made until a final product is ready. Some areas of improvements are suggested. .

The healing process of human bone can be aided by the presence of differentmaterials. A material that is transformed into bone when in contact with bone iscalled a boneconductive material. By transforming into bone the material reduces thetime that it takes to heal a fracture. This report is a study of existing boneconductivematerials on the market to see if there is a material available that would be suitable totest on larger fractures. The wanted application is to be able to heal fractures up to50 mm which is a fracture too big for the body to heal on its own.The healing process of human bone can be aided by the presence of differentmaterials.

A case study of professional interaction designers' usage of design materials was conducted. Five interviews were performed in order to gain insight in the systems used by designers, how these work, how they collaborate within them, and what they think of recent research about them. Design studios allow collaboration for several users at once. Digital material (mockups, pictures, etc.) are commonly used, but needs to be made analog, e.g. printed, to be usable in the design studio environment.

This thesis is covering my design of an architectural object for the use in a pedagogical setting. The purpose is to create contextual premises for students, making possible the testing of designs, involving plants suitable for the urban environment. Hence, the main features in the object design is suggestive to the urban outdoor rooms - rooms that are formed amongst the city facades. The thesis is also about the design process set out from a technical reality, based on camera imagery. To a large extent, the thesis consists of reflections concerning the object's function towards pedagogy, perception and materials. Furthermore, the object claims to be a hybrid between architecture and landscape architecture.

This essay examines how three big Swedish newspapers depicts e-sports and computer gaming and how the depiction change during 2000-2013. The study will also examine whether e-sports is being portrayed as competitive sport. The purpose is to investigate which attitudes that can be identified towards computer gaming and its culture in major newspapers such as Aftonbladet, Dagens Nyheter and Svenska Dagbladet and how these attitudes eventually changed over time. The sources that will be used in both the quantitative and qualitative analysis are based on web articles, mainly because the paper editions does not provide much, if any, information about computer gaming and e-sports and also because of the convenience of being able to quickly find articles to study. Results indicate that computer gaming is being depicted in a clear negative fashion during 2000-2006, and that the depiction of e-sports is somewhat positive but not as glorifying as for the years 2007-2013. During this period, there is a apparent tendency of e-sports being introduced to readers who are unfamiliar with the gaming culture. As for the attitudes towards computer gaming, the depiction is still somewhat negative, mainly because the debate about computer games and violence was revived because of several acts of violence in shape of school massacres and mass murder.

This is a thesis on D-level. In a previous course, at our program Computer Science, we came up with an idea of how to improve/complement training for new employees who are situated in a stressful workplace at companies who are in a constant need of rehiring. We developed this concept and came up with an idea for a simulator that could train staff as well as relieve stress and tension for new employees. The idea matured and became a Serious Game simulator based on a dual-wield Wii-controlled PC-based simulator with Bluetooth support.The purpose of this paper is to produce a design concept for a simulator as well as conducting research on the topics: mental and physical learning abilities, psychomotor abilities, visual perception, hand-eye coordination, confidence, simulators and Serious Games. The conducted research will be the foundation for the design concept which will be implemented in our co-workers', Henrik Djerf & Daniel Gomez-Ortega, prototype.

Visualization is a rapidly growing area of computer graphics. Due to the very progressive development of computer technology and especially 3D-graphic boards yesterdays imagination of visualizations, today is a reality. At Saab Bofors Dynamics in Linköping missile systems are developed. Through the development, different subsystems are simulated before the manufacturing starts. The results of these simulations have to be visualized to get a meaning.
