Studies in the field of interaction design and the human memory claim there can be positive effects on the memory when information is presented for the user as a graphical pattern rather than a series of numbers. This thesis aims to influence designers to choose graphical patterns as an interface for information display. Low-fi and hi-fi prototypes of graphical patterns were constructed and tested in a variety of configurations by two users. The users showed differences in the ability to memorize a sequence of digits depending on how this sequence was presented. This study suggests that users are more easily able to recall information presented via a graphical user interface than when the same information is only presented digitally..

Today, Ericsson Microwave Systems (EMW) uses non-graphical user interfaces in some of their Ada95 applications. EMW wishes to develope a more easy-to-use and platform independent graphical user interface (GUI) for their applications. To meet these requirements EMW has chosen to evaluate Java in GUI development with Ada95. To make it possible for the Java GUI to communicate with the Ada95 application, some kind of standardized interface is required. CORBA is a specification of such an interface.

The web sites of Swedish public libraries display a high level of heterogeneity when it comes to design and graphical user interface. The thesis is based on the opinion that the visuals of a public library web site have implications for the user as well as for the library. The design of the graphical user interface influences the attention of the user and his/her ability to absorb information. Furthermore, there is a connection between the visuals and the users opinion about the credibility of the content of the web site, as well as of the organisation itself. The research question is: Which factors may have an impact on the design of the graphical user interfaces of a public library web site? The purpose is to create an understanding for these factors and emphasize them.

GCM is a product information management system which handles data for consumer packaged goods. GCM was developed during the middle of the nineties and was acquired by Prevas AB in 2004. The GCM application relies on the services provided by the organization GS1, which supplies global specifications and validations for trade items across several sectors. GCM is updated regularly due to the frequent changes in specifications from GS1. However, the overall graphical user interface design has not been redesigned during these years.This dissertation studies possible improvements for the webpage that handles product data in GCM.

Already in the late 1970´s it became clear that the traditional catalogs in libraries were not suited for children, neither their interests nor their way expressing themselves were accounted for. The goal of this thesis is to investigate if and how children?s OPACs (Open public access catalogs) interface design is at present adapted to the presumed audience of children. My method consists of literature studies and an investigation on the Graphical interfaces in OPACs for children, according to the five criteria formulated by childrens library consultant Lena Lundgren and IT-consultant Kia Gumbel. The aims are to find out: a) what requirements for children?s OPAC interfaces and their usability are defined in literature and b) what the actual (real) features of the children?s OPAC interfaces are.

During the development of microwave based sensors such as radar target seekers, input signals are needed to verify the performance of the system. Therefore, a channel board has been developed by previous thesis projects at Saab Bofors Dynamics. It uses a technique called Digital Radio Frequency Memory (DRFM). The purpose of this board is to sample and digitally store radio frequency signals in order to reconstruct them after a certain delay.The aim of this thesis project was to use the channel board named above to construct a portable instrument for generation of stimuli signals. This assignment has been divided into two tasks: firstly, to construct and put together the hardware components and secondly, to implement a graphical user interface for the instrument.

Scania InfoMate develops web applications that support truck distributors and workshops with the necessary tools for an effective maintenance process. However, the end-users of these applications are faced with as many different Graphical interfaces as there are applications. As a consequence, important effects of recognition are lost, developers spend unnecessary time designing new solutions for each application and Scania InfoMate does not present a homogeneous brand image towards its customers.Therefore the aim of this study is to give a suggestion of how a standardized Graphical interface for web applications at Scania InfoMate should be designed. The given suggestion should come from thorough investigation of both end-user needs and recent research within the area of usability. In addition to a standardized interface this study also aims to deliver guidelines that support future web application development at Scania InfoMate.Through a combination of methods, mainly heuristic evaluation and user interviews, an elaborate description of usability and consistency problems in a defined web application portfolio is produced.

A degree project has been carried out at Motion Control, Västerås. The degreeproject ?Grafisk Skärm för Inbyggda System? have developed a first prototype of anembedded system with a display, a graphical user interface with touchscreen andpossibilities to communicate with external units.The work initiated with surveys of critical components. A technical specification forthe desired end product was developed. With the technical specification as support,design specifications for hardware and firmware were developed.After the specifications were done, a circuit diagram was developed and a circuitboard was made.

The Mobile phone has contributed to massive changes in the way that human beings communicate with each other and is a technology that is a part of society?s globalization. Opinions differ in the area of user interface where some feel that mobile phones exclude users such as senior citizens or users with an intellectual or a physical disability.Universal Design ??design for all?, is a vision that intends to bring about settings, products and services that suits as many people as possible irrespective of an individual?s needs and prospects. The criteria for ?design for all? are among other things flexibility, user friendliness, comprehensibility and a high tolerance for mistakes.The purpose of this essay is to investigate the mobile phones graphic user-interface from the theory of a universal design.

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.

Fastighetsregistret (The Cadastre) is a large and important information sourcesupplied by Lantmäteriet (the Swedish mapping, cadastral and land registrationauthority). Fastighetsregistret provides geographical information about the 3.2 millionestates in use in Sweden. Fastighetsregistret has a large number of users who trustthat the provided data is reliable, but experience shows that the data can have varyingquality. As a user it is not always possible to access more detailed information inorder to assess to what extent the data in Fastighetsregistret is reliable.The purpose of this master's thesis is to investigate the possibilities of a system with agraphical user interface that present, classify and visualize the quality of the data inFastighetsregistret. The defined user group for this suggestion is internal users atLantmäteriet who have a good understanding of Fastighetsregistret.

This master?s thesis was performed at PartnerTech AB in Åtvidaberg. It addresses the problem of managing test results obtained from testing electronics manufactured by PartnerTech. PartnerTech has developed a test system, called Tor, which performs tests on manufactured boards and stores the test results in files. The Tor system consists of both hardware and software part, where the software runs on an ordinary PC with MS DOS/Windows 2000.

This paper reports a study in how interaction design and graphic design is affected in the process of developing an mobile application to complement the use of an existing webbsite. The paper also ask how developers are affected in this process by the use of designpatterns. The purpous of the report was to see how designpatterns affects the development of mobile applications and how the interaction and graphic design differs between various company webbsites and their related application. A study was conducted by comparing three diffrent webbsites with three related applications to find material for our thesis. Interviews were conducted on three diffrent companys that work professionaly with creating mobile applications.

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.

This work aims to evaluate the possibility of using a graphical programming language to develop software for a digital signal processor. A fixed-point digital signal processor called Blackfin BF-537 is used for this. Instead of using conventional programming languages, like C or assembler, for software development the possibilities to use a graphical environment to fill the same purpose are examined. The development environment primarily used is NI LabVIEW, but also the use of Mathworks Matlab Simulink is investigated. A variety of programs consisting of various signal processing operations and utilities are developed using these development environments.
