In order to understand user behaviour and navigation patterns, user logging is today widely used in analysis and development of user interfaces. These user logs tend to be quite many and can contain a lot of different data. A big issue is how to process and display this data in a perspicuous way to the stakeholder. This study is about how to develop a prototype to handle this issue. It was solved by various methods from human-computer interaction.

Websites today only offer simpler form of technical analysis and are not fun to use, therefore student decided to build a website that makes technical analysis a bit more fun by giving user possibility to experiment with settings for technical indicators and also see clear visible results from analysis. Student decided to build website in ASP.NET. Technical indicators for this project only consist of those who give buy and sell-signals via cross-over, no divergence or pattern finding.This project has three questions that define this project. It?s important that there is good functionality so that performing an analysis is perceived as simple, one question is therefore; what functionality for website is needed in order for analysis to be perceived as more simple?Technical analysis is a pretty complex subject and demands an interface that is perceived as easy to understand and easy to use, it?s therefore important that the interface is well designed, second question is therefore; how should the interface be designed to be user-friendly?When systems grow large they often become hard to develop and later on unmaintainable because of the accumulated complexity and dependency between classes, the code is a mess, the last question is therefore; how can the systems complexity be eased with object-oriented design principles?Jakob Nielsens ten heuristics for User Interface Design were used as inspiration for designing the interface for the website.

Music production software has a strong tradition of two-dimensional Graphical user interface (GUI), in which the time line is represented as a flat composition either horizontally (from left to right) or vertically (from top to bottom). In my degree work titled Sequi, I approach music composition from a different angle. Instead of a two-dimensional time line with only two possibly ways of progression (forward or backward) I constructed a three-dimensional GUI with the maximum of four different ways of progression from any given point in a composition. The height axis is used to describe time-intervals (the time between downbeats) and the wide and depth axes are used to describe progression from one sound to another..

The most common types of smartphones in Sweden are iPhone and Android. Development in the IT feld is constantly changing and Windows Phone is a new operating system that has been introduced on the Swedish market in 2010. However, Windows Phone user interface is quite different from iPhone and Android.The numbers of applications for smartphones are increasing, and users are making greater demands on better  usability. Users want the application to be easy to understand and fast to bring into play.  If the application contains a bug or has other user problems, it can ruin the entire experience. If the user does not have a good experience of the application, the user will quickly stop using the application.Companies that do not have any mobile applications would probably begin with an iPhone application.

Computer use at work has risen considerably over the past fifteen years and is currently a relatively common phenomenon when 76 percent of women and 72 percent of men using the computer in their daily work (SCB Arbetsmiljörapport 2009).According to Gulliksen and Göransson (2009), Sweden is one of the countries which are more advanced in the procurement of computer systems at work. He means that Sweden has unique opportunities and conditions for user participation in the development of computer systems, when the user has the right to influence their working environment through a law in the Work Environment Act. The paper examines the importance of user involvement in system development and the Swedish company's approach and experience of user involvement. To highlight and explore the importance of user involvement, there has been a case study in which users have been representative of the development process. The case study has been conducted on a case company where the system IST analys was in need of a new interface.

The division of Engineering Materials at Linköping University, department of Management and Engineering, conducted a research project concerning Fatigue life of thermal barrier coatings during 2009. During this project equipment to provoke these fatigue failure by rapidly heating and cooling test subjects in cycles, was ordered.Design and manufacturing of the equipment was handled internally at LIU.The equipment was built using a furnace that is lowered and raised over the table where the test subject is placed. To keep the temperature of the furnace a lid slides in place to close the downward facing opening of the furnace when it is in the raised position. On this door there is nozzle that is used to cooling of the test subject by air.To make sure that the equipment can work independently you need an automation controller that can evaluate if movement can occur without danger of collisions. The control system also needs to monitor that all elements are performed according to plan.This degree project is based on a modular system from OPTO 22 and includes the configuration of a PLC that will be supplied with logic and a user interface.The degree project resulted in a graphic interface in which a user can set desired values for different parameters and get information about current values for them.

At Saab Aerospace in Linköping, components for measurement systems to the fighter aircraft JAS 39 Gripen are developed. In this activity you sometimes want to record the traffic transmitted on the data busses that connects different sys-tems. This traffic on the data busses is using the military standard MIL-STD-1553. This project has aimed to create a system for recording and sending 1553-data. The system is used on an ordinary personal computer, equipped with a recon- figurable I/O card that among others has a programmable logic circuit (FPGA).

Man's life has changed in many ways since technology made it?s entry for public at large. In response to this change the science of human-machine interaction was invented. It has in turn evolved into human-computer interaction. With this science the focus is on the customization of the system for the actual person who will use it.The thesis has been implemented in a telecom company's development department.

In recent years seemingly everything has become digital. Some areas, like classical sports, have been slower to adapt to new technical development. Golf is an example of this. Usually when people play golf they bring their clubs, golf balls and a paper scorecard on to the golf course. The advantages of keeping score in a digital way areevident.

The projects goal was to make an already existing indoor positioning system useful forthe average smartphone user. This was achieved by creating an Android applicationwhich, along with a running server, continuously presents the user with all the currentneeded information. It uses the graphics engine andEngine to create the graphical userinterface. The application was created in the development environments Eclipse andAndroid Studio..

This study is an evaluation of the runtime watch function in a OEE software, knownas ProTAK. OEE stands for Overall Equipment Effectiveness, it?s a way to measurethe factories process efficiency. The runtimewatch function allows the user to setup and monitor certain critical objects that are of importance for the pulp and paper process at the mill. The data from the runtimewatch can be correlated towards the suppliers specification for the components.

In this final thesis two simulation models have been integrated. The simulation models are models of JAS 39 Gripen?s fuel system, software and hardware. The time consuming and costly work to develop software has made the department of fuel system to build two models in Xmath/Systembuild. The software model also simplifies the comprehension of how the software in the control computer of the fuel system works.

This study concerns design thinking and how to achieve usability when designing applicationsfor smart watches. The study's focus is on interaction and design for online auctionapplications such as Ebay and Tradera. After studying usability and design for devices withsmall screens, guidelines and design principles for interactive systems, we developed apaperprototype for an auction application. The prototype was used for testing our intervieweeswhile observing and asking questions. After collecting the data we analyzed the responses andfeedback on our prototype and combined the results to previous studies.

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.
