Uppkomsten av dagens Web 2.0 har skapat möjligheter till större interaktivitet hos användarna. Denna utveckling har även följts av en möjlighet att skapa användargenererat innehåll, ett fenomen som benämns User Generated Content (UGC). En av de viktigaste aspekterna inom UGC är att det måste uppnå en god användbarhet, men likväl måste tjänsterna också erbjuda en rik subjektiv upplevelse. Denna subjektiva upplevelse benämns som User Experience och är ett uttryck för den upplevelse och tillfredställelse en användare känner då den ställs inför ett interaktivt gränssnitt. Syftet med uppsatsen var att identifiera User Experience av UGC-tjänster.

The power system modelled in this thesis work has been developed for simulationwhen e.g. the production in some part of the power system is changed. The powersystem has been modelled according to the swing mass of the system, the frequencydependency of the load and the turbine governor. The model determines the systemfrequency, the period of regulation and the power exchange between the differentsubsystems in the Nordic synchronized system.In this model the system frequency is assumed to be the same in all different parts ofthe power system and the voltage conditions in the power system are neglected. Forthat reason power swings does not occur between different subsystems in the powersystem, which usually occur as a result of the swinging connection between thetransmissions line.

This essay focuses on the term usability while conducting a user centred system design. Usabilitymeans to what extent a user can use a product to achieve effectiveness, efficiency and satisfaction.Development using a user centered system design means that knowledge about the end-users andit?s opinions becomes a crucial part of the development process. The question of this essay is if usinguser centred system design will lead to good usability.We used methods from a user centered system design point of view while developing an applicationfor a Swedish bookstore company called Bokia AB. This included user and task analysis following by aclose relationship between the developers and end-users by using sketches and showing themprototypes of the system while collecting feedback.After concluding our case study we determined that using methods from user centered systemdesign could be used as a great tool to further improve the usability and to improve an applicationssuccess chances..

Vår uppgift har varit att skapa ett grafiskt användargränssnitt till en pick and place maskin eftersom den ursprungliga programvaran inte fungerade på ett tillfredsställande sätt. Programmet är implementerat med C++ som programmeringsspråk och är designad på ett sådant sätt att vidareutveckling kan ske om så behövs. Programmet är begränsat till att användas tillsammans med tidigare utvecklad programvara för denna maskin. Rapporten beskriver det grafiska användargränssnittets delar, både hur de fungerar och hur de är implementerade..

In my exam-project, ?For Götha Kendo Club ? an athletic clubs new graphical profile? at HDK ( School of Design and Crafts ) i chose to redesign the visual identity of Götha Kendo Club, a kendo-club in Gothenburg. Kendo is a japanese fencing sport, where swords of bamboo are used, together with protective armor.My work consists of a new logotype for Götha Kendo Club; three different posters for recruiting beginners; a website layout, presented with a pdf-file; and a beginners folder, with an introduction to kendo.The aim was, not only to give Götha Kendo Club a new fresh look, but also to attract a target group to the sport, namely people who are interested in competition, exercise and athletics.To achieve this I created a though look where tension and focus was the lead; using only three colours, red, white and black, and with progressive typography set in with the modernistic HouseGothic typeface I created this fresh and exciting look. The photography by Ida Nordung where shoot with white backdrop, creating a hard contrast to the dark clothed kendo models.Finally I collected rules and guidelines for the graphical and visual elements of Götha Kendo Club new style in a graphical guide..

IKEA HaparandaTornio employ some two-hundred people in its furniture retail store.Keeping track of staff statistics and employee information has previously been achievedthrough the use of a basic Microsoft Office Excel spreadsheet. The store?s human resourcesdepartment requested an upgrade to this system with the hope of speeding up andsimplifying the administrative process, as well as to make it easier to monitor HR-relatedtarget statistics. 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.

Theory has concluded that consumers evaluate advertising not only based on what the advertiser's message aims to communicate, but also how the message is communicated. As the most popular activity on the world's largest social media channels is to upload and share photos, it has become crucial for advertisers to define strategies that maximize the reach of photo posts. Two observed variations of images used in posts are graphical images and digital photographs. The aim of this study is to investigate which of these two strategies that generate most positive impact on the sender and its brand. 230 users of the Chinese Facebook and Twitter counterpart, Sina Weibo, were exposed to manipulated Sina Weibo posts after which they answered a survey.

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.

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..

This is a thesis project in the field of information technology which begins by evaluating existing food price comparison systems and subsequently aims to design an improved, web based system for said purpose. The system features interfaces for price reporting, price comparisons as well as various search and review functions. The objective is to create a system able to compete with existing price comparison systems, which requires careful selection of products that can be found in all foodstores that also represent different households; a user-friendly price reporting and price comparison interface and an efficient tool for ensuring the validity of reported prices.The designed system features a more accurate formula for calculating average prices in events where the real price is missing; a more reliable security mechanism forv alidation of reported prices and a more comprehensible interface for viewing price reports, reporting prices, reviewing stores and products in comparison with existing systems. The system does, however, suffer from some optimization issues primarily in the form of inefficient database modeling; SQL queries and JavaScript code although testing has shown that these shortcomings do not hamper overall performance to such a degree that usability is compromised. Further usability testing performed on the system with five test subjects shows that a high level of overall user-friendliness has been achieved even though some special features, such as the detailed report containing price information per product for each store need to be improved.It is not possible to say at this time whether or not the designed system will be able to compete with existing ones or if the very concept of food price comparisons per se is viable in terms of profitability and marketability.

This paper deals with the difficulties of applying user-centered design practices as an independent developer, based on the visualization of a game concept in the form of a prototype. The aim is to evaluate the usability of user-centered design practices, specifically in the field of games development. Throughout this paper, I will give an account of the methods used for testing, as well as a review of previous research done in this field of study. Finally, I will end with a discussion regarding the pros and cons of user-centered design, as well as some thoughts about its importance in similar projects..

At the department of Electronic Warfare Assessments at the Swedish Defence Research Agency in Linköping one of the activities is modelling and simulation of the duel between a robot and a target. The aim with this Master's thesis is to develop a simulation model of an hovering helicopter. First a theoretical description of the forces and moments acting on an helicopter is given. Then the equations of motion are derived. These equations are simplified to be valid only for a hovering helicopter and the result is a mathematical model.

New technological innovations like tablets and smartphones have a taken significant market share on the web and puts new demands on webpages, the user interface and compatibility among different client devices. The full test of a web-based system prior to the publication is often regarded as an important part of the process to create a complete and successful website. This bachelor thesis investigates the possibility to analyze mobile-adapted web sites using a system that first records the visitor's activities and then replays them for an expert analyst to provide valuable information to developers about how their site can be improved.The essay begins with a litterature study on today's most common web development tools and then examines the possibility to apply them during the development of the analysis tool. The work also describes two methods, pair programming and waterfall method used during the project. Three different evaluation methods are presented and one of the models is applied on the finished system.The project results in a web-based analysis tool written mainly in JavaScript using the jQuery library.

In visual programming the developer specifies her code, using visual tools. Within the range of visual programming languages lay icon-based languages, form-based languages, and diagram languages.Mediator is a multimedia authoring tool that allows the user to create interactive CD-ROM presentations, dynamic HTML pages and Flash projects, without any coding or scripting. The user can create interactivity in her project, using event driven and icon-based visual programming, through a ?drag and drop? user interface. This report intends to determine some of the qualifications of a tool of this kind, as well as its limitations.The report is based on a case study, in which a smaller software application was to be updated using Mediator 9.
