This Master Thesis documents the development of an On Board Diagnosis (OBD-II) Interface for remote diagnosis of vehicles. The Master Thesis is part of a project at the company Wayfinder Systems in Lund. The purpose of this thesis was to design a scantool that communicates with a vehicle through its OBD-II port using relevant standards. In order to make the OBD-II Interface development easier, a car simulator was first built. Both the car simulator and the OBD-II Interface were implemented using a linux computer running a C-program with serial communication with an external electrical Interface.

This master thesis project will describe and evaluate the Interfaces between applications and Controller Area Network, CAN, Interface boards from different manufacturers. The Interfaces have corresponding functions but the usage of parameters is different. The simply communication of sending and receiving messages is more alike than the supplementary functions between the different Interfaces. The CAN communication is more controlled by the CAN protocol and is therefore more alike. The evaluation shows differences and similarities between different Interfaces and also difficulties and options to translate them.

The purpose of this study is to evaluate an existing user Interface. The company in question has a web-based user Interface (available through logging in via their website), but they are interested in making the process of using the Interface more convenient and the Interface more accessible, so that users without a background in computing can properly manage the Interface. At the same time they want to apply additional functionalities in order create and to manage increased traffic on the company?s website. For this reason it is important to take into account the issues involved in human-computer interaction (HCI) as well as aspects of cognitive psychology in order to make the tool and the web Interface more usable, more motivational, and therefore more efficient and professional.

For this essay we used pattern theory from Interface design and applied it in an analysis of touch games. In order to make full use of the patterns, we selected five of them and adapted these slightly with the help of game related patterns to be useful for the framework of this essay. The selection of games were the top eight games on the App Store?s ?What?s Hot?. The results showed, among other things, that the games had a clear focus on getting a pleasant apperance, and they did it relatively well.

The purpose of this report has been to develop an administrative web Interface. The web Interface is to be used by the company Zidango and it is going to make it easier for them in their daily work of running a web portal. The Interface had to be developed so it would fit in Zidangos web portal. This meant the work had to be done in the framwork Struts and mostly in JAVA. Thereforeis a shorter theory chapter included in the report that discusses frameworks.

To efficiently examine volumetric data sets from CT or MRI scans good volume rendering applications are needed. This thesis describes the design and implementation of an application programming Interface (API) to be used when developing volume-rendering applications. A complete application programming Interface has been designed. The Interface is designed so that it makes writing application programs containing volume rendering fast and easy. The Interface also makes created application programs hardware independent.

This thesis investigates how different Linux-distributions installation Interface relate to the ISO 9241 standard, parts 12 and 13, and how they relate to the installation Interface of Windows XP, with the hypothesis: "There is a Linux-distribution whose installation Interface according to applicable HCIrecommendations is equivalent to that of Windows XP." With the checklists provided by ISO 9241 an empirical study has been made, and so comparable measurements of how well the Linux-distributions and Windows XP follows the recommendations of the standard was obtained. By comparing the results from the tests similarities and differences between the installation Interfaces can be deducted. As the result and the conclusion shows there are Linux-distributions whose installation Interface, according to the applicable HCI-recommendations, are equivalent to that of Windows XP..

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.

The purpose of this thesis was to create a communication Interface which insures that all the right hardware is in its right place in the IS-node before Ericsson AB delivers it to their customers. One of the first parts of this work was to make sure it is possible to create such an Interface for IS. This thesis then explains how to construct an Interface that retrieves information from the IS-node into a C#-application. One important part of this project was to collect information and transform it to an XML output with the purpose of then being used in other applications in the future. The application created within the scope of the thesis exports the information retrieved from the IS-node in an XML-file or a text-file.

I have in this thesis studied how guidelines for organizing information in a custom- made user Interface could be made. Teletal is service with a special designed user Interface were information is stored. The purpose of this study is to encourage a consistent organization, and management of information in a user Interface. The methods used in this study are as follows ? qualitative interviews and two card-sorting tests, of which one was closed and the other open.

BarnOPAC is a Swedish library Interface for children. It was launched in public libraries in Sweden in 2001 and has now become a part of library software equipment in several public libraries. The purpose of the thesis is to investigate the Interface BarnOPAC on the basis of the childrens perspective. The questions raised consider: how children experience and handle this Interface, how library staff experience it and what viewpoints librarians have on childrens use of it. For this purpose we implemented a user study including eight children using the Interface in a school library.

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.

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.

Research is a time-consuming endeavor which requires appropriate tools to manage often vast amounts of information. Militarization 2.0 is a research project aiming to explore Militarization in social media. The aim of this project is to design a user Interface for supporting researchers in projects involving large amounts of data in qualitative studies. The project will follow the design process of the first version of the Militarization 2.0 research database Interface. The design process involves user studies, interviews and design and testing of paper and digital prototypes.
