Att sätta sig in i system kan vara krångligt utan rätt sorts dokumentation. Vi har undersökt vilken dokumentation som kan vara lämplig att lämna över till nya utvecklare, som ska arbeta vidare med systemet i software maintenance fasen.Det har gjorts genom att vi har gjort en litteraturstudie om dokumentation samt undersökt vad för dokumentationsartefakter som används när man ska sätta sig in i datorsystem. Vi använde eXtreme Programming för att utveckla ett system som vi försökte dokumentera samtidigt som vi utvecklade det.eXtreme Programming förordar muntlig kommunikation, vilket är svårt att lämna över till nya utvecklare. Vi upptäckte under vår utveckling att det var svårt att föra in dokumentation sam-tidigt som utvecklandet pågick,  därför använde vi bara enhetstester och  strukturerade kod-kommentarer under utvecklingsiterationerna.Vi undersökte hur dokumentationen som skapats fungerade genom att göra en undersökning bestående av strukturerade intervjuer där de fick komma med kommentarer om hur dokumen-tationen hjälpte förståelsen för systemet.Vi lämnar ifrån oss en vidareutveckling  av eXtreme Programming  som innefattar en doku-mentationsiteration  innan överlämnandet  samt en studie om vad för dokumentation som är värdefull att ha vid systemöverlämningar..

In this essay we discuss the broad area of website usability from a tourism perspective. Our goal was to investigate the usability in smaller and bigger tourism websites. We have declared what website usability means and the importance of involving the users when designing a user interface. In a pilot study, we conducted three interviews with people who work with usability and then used the information we got to form questions to use in a focus group interview. In this focus group, we asked three people to assess two Swedish tourism websites, one bigger and one smaller, to find out if they were considered usable and if there was any difference in usability depending on the size of the site.

I den här uppsatsen har faktorer för en ökad användaracceptans och diffusion av Video on demand(VOD)-tjänster identifierats med hjälp av en litteraturgenomgång av tidigare studier i acceptans och diffusion. Litteraturgenomgången ligger till grund för en lista av faktorer som gör en konsument mer villig att anamma en VOD-tjänst. Faktorerna har sedan utvärderas genom en kvantitativ undersökning med hjälp av en webbenkät. Resultatet blev i stor grad det som förväntat där det framgår att utbud och kostnad är de viktigaste faktorerna för en hög acceptans, men även andra faktorer kan spela in som användarvänlighet, kvalitet och sociala faktorer..

This document is a summary of my work to create a project management system for a small firm working with computer graphics. The intention is to manage customers, projects, images and invoices in the easiest possible way. To make the system as flexible as possible a web-interface was chosen which makes it possible to access the system from any computer, making it independent of any particular operating system. The only requirement on the user environment is that the computer must have a connection to the Internet to be able to access the system. The different techniques that have been used to develop the project management system is primarily Ruby on Rails and a MySQL database.

Ett användarinterface i Excel kan återskapas på ett strukturerat sätt i Qt. Programmet Qt är lättanvänt för någon med programmeringserfarenhet, men svårt för andra. Qt finns som gratisversion och är baserat på programspråket C++.Tågföretaget Bombardier använder ett interface i Excel, men med nya versioner av programmet har problem uppstått. I detta projekt undersöks svårighetsgraden av Qt och delar av Excel-interfacet återskapas i Qt.Först skapades en design i Qt med bland annat tryckknappar, komboboxar och textfält. Sedan skrevs kod för designens funktion.

We have different kinds of signal processing everywhere around us in our everyday life, in our cellphones, when we are listening to music, watching TV etc. This makes signal processing a very interesting and important technical area, where the demand of skilled engineers sets the limit of what is possible.Working with signal processing requires in-depth knowledge in areas such as mathematics, physics, electronics, and other related areas. For this, it has traditionally been demanded by a talented developer to also master the advanced programming languages such as C / C + + and Assembler.This has begun to change; today there are several companies that offer graphical development environments for signal processing, environments where programming skills are not needed anymore, and the focus can be on signal processing instead.The goal with this project is to build a corresponding graphical development environment to reach an understanding of what is required of these systems, and also to grasp what opportunities that are available within graphic programming. Inspiration for the work has partly arise from some of the tools available on the market, and partly from previous theses that have been written about graphic programming.The challenge lies in creating a program that can execute signal diagrams in real time from given signal blocks, and be able to handle feedback loops in an efficient way and to do so at the lowest "cost" in terms of clock cycles as possible. This should also be compared against to code, compile and run a complete signal diagram directly.To increase the usability it should also be possibility to externally manage in real time the parameters of the signal diagram during execution.The interface is a separate program, which is to some extent similar to Matlab Simulink, where a signal diagram is drawn up graphically by connecting wires between different signal blocks.

The Division of Language and Communication at Chalmers uses a web-based language tool, named EngOnline, to teach English grammar. The language tool suffers from some shortcomings. These include stability problems and an outdated interface but, above all, there is no documentation. Because of the lack of documentation and EngOnline?s need of maintenance, the Division of Language and Communication has decided to replace the language tool with a new and well documented one.The new language tool was developed using an agile work process; detailed documentation was replaced with more efficient communication.

In my paper I adress the question of what happens in the relationship between the beholder, the artwork and the artist when they meet in the era of Web 2.0. The new smartphone based medium that I write about is Instagram. The artist i write about is the Swedish illustrator Jesper Waldersten. My purpose with this paper was to explore how the the beholder, pictures and artist relate to one another i relation to Instagram and how the interface of the smartphone and the app affect the beholder in these relationships. I also seek out to understand the difference between how Instagrams interface affect the beholder in comparison to the interface of the artists web page and his book.

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.

With the increase in IT related crimes the IT forensics has more work ahead of them and it is constantly rising. The analysis software called EnCase is widely used by IT forensics all around the globe and with it comes an internal programming language called EnScript.This paper is designed to examine whether a manual for the programming language EnScript can make a difference in how efficiently the work is.A study between two groups has been made and an evaluation of the results between the two groups.The manual provided aims to introduce the reader to EnScript as a programming language and also to provide a solid foundation to build on in further work with EnScript.

This report contains a programming improvement work in a LabVIEW? fire testing furnace control system for SP Fire Technology in Borås. Here materials and products behaviour are tested and evaluated, being exposed to fire. For this task, UGNET is being used for control and surveillance of the testing furnace system. System hardware has been updated gradually through the years, while the software has been neglected.

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.

The purpose of this study was to investigate the possibility of streamlining the test process by utilizing pair programming. During the process, pair programming has been practiced as is defined by the Extreme programming (XP) software development methodology, with the other aspects of XP discarded. The focus of the testing itself has been toward unit testing. The methods applied has been with an experimental approach where 93 cases were attempted to be solved by either single programmers or pair programmers. What has been investigated in these experiments was the time needed to complete a case, how many test attempts were needed to solve the case, and how high a percentage of the cases were solved.

The scope of this master´s thesis is the issue of usability in relation to interface design,in particular the interface of a university library´s online public accessed catalogue, orOPAC. Since the OPAC can be seen as the library´s ?shop window? to the world, it isof great importance that the interface to the OPAC can be used by patrons witheffectiveness, efficiency and satisfaction.The master´s thesis is based on a qualitative study performed at Karolinska InstitutetsUniversity library, and contains both a usability evaluation and an interview study. Twointerfaces were evaluated: a standard web interface provided by the system supplier, andan interface developed in-house by Karolinska Institutet´s systems department. The twointerfaces are both connected to the same online library catalogue, thus making possiblea comparative study..
