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..

The way we interact with computers will soon change dramatically. The input Interfaces are becoming more and more intuitive and one of the latest technologies is a touch screen Interface capable of dealing with multiple inputs simultaneously. The tools we use to communicate with the computer - such as the mouse and the keyboard, will slowly disappear and be replaced with tools more comfortable and more natural for the human being to use. The purpose of this project was to create a basic framework for future projects dealing with this Interface, as well as creating some example programs. This report describes my work and my experiences with this new Interface..

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 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.

In the future network-based Swedish Defence (NBD), attaining information superiority will be of great importance. This will be achieved by a network of networks where decision-makers, information- and weapon-systems are linked together. As a part of the development of NBD, we have performed a study of user Interface design for a future network-based tool package for analysis of sensor systems, referred to as the C2SR-system. This thesis was performed at Ericsson Microwave Systems AB, Sensor and Information Networks, during the autumn 2002. A pre-study concerning the requirements of usability, trustworthiness and functionality of a user Interface for the C2SR-system was performed.

This thesis project is based on a business idea where users can design their own t-shirt online. The project shows the first step in the development process where a prototype for a user Interface is created and evaluated.The purpose of this thesis project is to answer the following question:How does one develop a user Interface for t-shirt design with consideration to interaction design theories?In order to answer this question the design process began with scheduling the work at hand. The first step was to build a conceptual model based on specifications made prior to this project. This conceptual model became the foundation for the physical design.A high fidelity prototype was created using Macromedia Flash and Actionscript 2.0.

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.

This essay explores to what extent the Swedish language version of Google Images meets the usability requirements of average everyday users. Previously published studies on user behaviour and users? Interface and search option preferences define the usability requirements, which are matched against Google Images? actual Interface and search options. The retrieval method of Google Images is also briefly discussed, and users? opinions about Google Images too, as they come across in the previously published user studies.The findings are that Google Images lack some of the things that users ask for, but it still seems to be the most used image search engine among average internet users and more appreciated than other search engines.

This thesis describes the process of developing a reservation system for common resources through a TV-Interface. The system is developed in cooperation with the company Dreampark and is built to work in their platform for TV, Dreamgallery. The main goal was to develop a reservation system and to make it work with Dreamgallery, to develop a demonstration version of the system. The thesis describes the approach for developing an easy-to-use and customisable program and Interface for making reservations. How this is inserted into an existing program in a suitable way.

This thesis has been performed at Scania CV AB Technical Centre in Södertälje and its aim hasbeen to study the causes and effects of deformations in the Interface between the rear axlehousing ADA1100 and the central gear house R780 during operation. Design changes that wouldincrease the sealing capability of the studied Interface are also suggested. Finite element (FE)and CAD software have been the primary tools in this study.Finite element (FE) simulations are used in the industry to predict and develop engineeringdesigns. The main motive for FE simulations has traditionally been to identify weak spots in thedesign, regarding high tensions and large deformations.The FE model is an aggregation of submodels and Interface models that represents the rear axlehousing, suspension, central gear, central gear housing, wheels, bolts and weldings, and theirinteractions. The submodels have different material properties and they are connected withcontact Interface models.Boundary conditions are defined on the bushings in front of the rear axle and on the air bellowsbehind the rear axle.

Due to a growing interest in communication in today?s society the demand for equipment that is used in communication networks increases while the competition between companies that produce this equipment grows. To meet the increasing demand and at the same time having a competitive product development many companies use some effective product design, such as the modular product design. When a modular product design is used it?s good to compare different module configurations for a certain product and to simplify these comparisons some tool can be used.

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.

This paper reports a study on the usability of e-commerce accessed through smartphones. There is much research in the usability of mobile Interfaces and many sets of design patterns have been created but a few studies are available for specific domains, and in this report we focus on mobile e-commerce. In this study a framework is developed for how to design mobile e-commerce Interfaces with a high degree of usability. Furthermore, the study also contributes a method to how other specific domain can develop a framework with general standards to work from when creating a web Interface. By examining two sets of design principles and 14 design patterns, we evaluate which ones are critical in the design of a mobile e-commerce Interface for achieving a high degree of usability.
