In the context of building software systems, Service-oriented Systems (SOS) have become one of the major research topics in the past few years. In SOS, services are basic functional units that can be created, invoked, composed, and if needed deleted on-the-fly. Since these software systems are composed of different services there is no easy way to assure the Quality of Service (QoS), therefore, formal specification of both functional and extra-functional system behaviour, compatibility, and interoperability between different services have become important issues. As a way to address this issues, resource-aware timing behavioural language REMES was chosen to be extended towards service-oriented paradigm with service specific information, such as type, capacity, time-to-serve, etc., as well as Boolean predicate constraints on control flow guarantees. In this thesis we present a design framework that provides a graphical user interface for behaviour modelling of services based on REMES language. NetBeans Visual Library API is used to display editable service diagrams with support for graph-oriented models. A textual dynamic service composition language was implemented, together with means to automatically verify service composition correctness. We ensure also an automated traceability between service specification interfaces, where both modelling levels are combined in an efficient tool for designing SOS.

The growing demand for UI test automation has triggered the development of many tools. Researchers and developers have been continuously working to further improvise the existing approaches. If we look at GUI test evolution we can observe a clear progress from manual testing towards complete automation. Numerous approaches have been made to automate the GUI testing process. Record and playback tools, key-word driven methodologies, event flow exploration strategies, model based approaches are continuously evolving with higher level of automation. Similarly, new ideas and strategies to make these tests efficient are also emerging. Optimization of this resource consuming activity is another very important aspect in this area.  Dependencies between different tests can create deadlock scenarios, while running larger test suites. A concept of Ordered Test Suite can be used to cope with such dependencies. Following the Model Driven Architecture initiative by Object Management Group, a new global trend of Model Driven Engineering is creating a big sensation in the field of model based software development. Using the same principle, studies have also been made to automatically generate tests from models. Behavioral models can be made using the model driven approaches and these models can be analyzed to generate tests automatically. This master thesis addresses different approaches made for Graphical User Interface test automation, some optimization issues and solutions, a case study done at a software company to automate User Interface testing and a model driven approach for automatic test case generation.

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 userinterface for the C2SR-system was performed. Officers representing the future users in the NBD played an important role when gathering these requirements. Another important part of the pre-study was the evaluation of software that contains parts of the functionality necessary for the C2SR-system. On the basis of the results from the pre-study, we have designed a user interface to the future C2SR-system. To demonstrate the most important conclusions, a prototype was implemented.

Graphical user interfaces for high-assurance systems must fulfill a range of security requirements such as protected and reliable presentation, prevention of unauthorized cross-domain talk, and prevention of user-input eavesdropping. Additionally, it is desirable to support legacy applications running in confined compartments. Standard isolation methods such as virtual-machine monitors provide one frame buffer per security domain, where each frame buffer is managed by one legacy window system. This raises the question of how to safely integrate multiple (legacy) window systems and protect the displayed data while preserving the usability of modern user interfaces. Our paper describes the OverlayWindow System, a general mechanism for multiplexing windows of multiple distinct window systems into the host frame buffer. Thus, each legacy window appears to the user as one corresponding host window that can be moved and resized. To achieve this, only slight modifications of the legacy window system are required whereby, the source code does not have to be available. Our implementation of an Overlay Window System successfully multiplexes Linux, GEM and native L4 applications.

<p>Implementeringen av tredje generationens mobila nät (3G) har lett till att nya användningsområden skapats inom mobila tjänster. Bandbreddens ökade kapacitet gör det nu möjligt att skicka betydligt större mängder information än i tidigare mobila nät. Detta har även medfört att nya tjänster skapats för 3G-mobiltelefoner. Ett område under utveckling är mobil turistinformation. Mobila Guiden är en mobil turistapplikation som TelecomCity i Karlskrona tagit fram. Det är en guide över världsarvet i staden som presenteras på en 3G-mobitelefon. Användarna får en karta över Karlskrona centrum med olika besökspunkter som innehåller information i form av text, bilder och ljud.</p><p>Det finns dock vissa problem när det gäller mobiltelefoner. Den förhållandevis lilla skärm som de har gör informationspresentationen komplicerad. Det är svårt att designa program som tillfredsställer användarna. Inom databranschen har Human Computer Interaction och andra områden inom gränssnittsdesign studerats men när det gäller de betydligt mindre skärmar som en mobiltelefon har så är forskningen inte lika långt framskriden</p><p>Syftet med detta arbete är att utifrån ett användarperspektiv analysera och identifiera hur en mobil applikation för 3G-nätet som presenterar turistinformation bör designas för att intressera och tilltala användaren. Fokus ligger på att applikationer av denna art i framtiden skall tilltala ett brett användarkollektiv. Resultatet av vårt arbete skall ge normativ kunskap och ses som ett vetenskapligt bidrag i utvecklingen av framtidens informationspresentation i mobila nät.</p><p>Studien påbörjades med en genomgång av befintlig litteratur. Sedan genomfördes en fallstudie med kvalitativa intervjuer för projektet Mobila Guiden i Karlskrona samt en fokus-gruppsdiskussion. Vi använde sedan en avslutande surveyundersökning för att få kvantitativa åsikter om gränssnittet i applikationen. Utfallen från intervjuer, fokusgrupp och surveyundersökningen analyserades sedan i förhållande till utvald teori.</p><p>En mobil turistapplikation måste presentera ett brett informationsutbud som exempelvis en karta med sevärdheter, mat, boende och evenemang för att tillfredsställa användarna. Användbarheten bör vara av sådan art att det skapas en dialog mellan applikation och användare. Användaren måste även få feedback och information om hur programmet används. Färgvalen bör också noga beaktas då tydlighet är ett måste på en liten skärm. Individuella inställningar för bildspel, textstorlek och ljud bör finnas tillgängliga. För att användarna ska vara nöjda med applikationen bör också helhetskvalitén runt tjänsten vara tillfredsställande.</p> / <p>The implementation of the third generation of mobile networks (3G) has led to a creation of new areas of use within mobile services. Increased capacity of the bandwidth has made it possible to send a considerable amount more data than in the predecessors of 3G. It has also led to new services within 3G. One area which is under development is mobile tourism information. Mobila Guiden is a mobile tourismapplication which TelecomCity, Karlskrona, has developed. It is a guide over the world heritage in the city which is presented on a 3G mobile phone. The user is presented with a map over Karlskrona City on a mobile phone with different points of interest. These points include information in the form of text, pictures and sound about the object.</p><p>Certain negative aspects regarding mobile phones surface under the discussion. The screens on mobile phones are relatively small which makes information presentation complicated. It is hard to design the user interface for applications so that the users becomes satisfied. Within the computer industry, Human Computer Interaction and other areas concerning user interface has been studied, but when it comes to the small screens of mobile phones the research is not that widespread.</p><p>The aim of this report is that from a user perspective, analyze and identify how a mobile application for the 3G-network that presents tourism information should be designed to satisfy user needs. We focus on that applications of this kind in the future should appeal to a broad customer base. The result of this report will give normative knowledge and be regarded as an academic contribution in the future development of information presentation in mobile networks.</p><p>Our investigation began with a study regarding existing literature. Thereafter a case study with qualitative interviews relating to Mobila Guiden in Karlskrona took place along with a focus group meeting later on. We finally used a survey to get quantitative data regarding opinions of the user interface of the application. The results of the empirical study were then analyzed in relation to appropriate theories.</p><p>A mobile tourism application must present a broad range of information to satisfy the users, for example: a map with sights worth seeing, restaurants, hotels and happenings. The usability should consist of the creation of a dialogue between the application and the user. The user must receive feedback and information on how to use the application. The choice of colour should be taken under consideration since the screen size makes it imperative that the user interface is clear and easy to understand. It should also be possible to make individual adjustments regarding the speed of a picture slideshow, font size and sound.</p>

<p>Tools development is a sometimes overlooked process that is crucial for developing high quality games. The experience of the users will vary which makes usability an important issue as well as having good guidelines for communications and development of user interfaces. This report presents the development process of two different tools used in production of high-quality projects at Avalanche Studios and describes both the added functionality as well as the methods used to provide them.</p> / <p>Programmering av verktyg är en process som ofta är förbisedd men som är mycket viktig för utvecklingen av hög-kvalitativa spel. Den varierande kunskapsnivån hos användare gör att det är viktigt att fokusera på användarbarheten samt även ha bra riktlinjer för kommunikationer och utvecklingen av användargränssnitt. Den här rapporten presenterar hela utvecklingsprocessen av två olika verktyg som används vid utveckling av högkvalitativa projekt vid Avalanche Studios, och går igenom både ny funktionalitet samt även använda metoder för att uppnå detta.</p>

Museums can be perceived as stuffy and forbidding; web technologies can enable museums to expand access to their collections and counterbalance these perceptions. Museums are searching for new ways to communicate with the public to better make a case for their continued relevance in the digital information age. With the emergence of multitouch computing, other diverse forms of digital access and the popularization of the user experience, challenge museum design professionals to synthesize the information seeking experience that occurs on multiple computing platforms. As a means of addressing these issues, this Master’s Report summarizes the One Butterfly design project. The project's goal was to create a design for a multitouch interface for federated search of Smithsonian collections. This report describes the project’s three major phases. First, an idea for an interface was developed and designs based on that idea were captured and clarified. Second, a formal review of related research was undertaken to ground these designs in the museum informatics, user interface design, and multitouch interaction design literatures. Finally, the report concludes with a review and reflection on the designs and their underlying ideas in light of things learned in the previous phases. / text

Šiame darbe sprendžiama mobiliųjų įrenginių internetinės vartotojo sąsajos vartojamumo problema, kuri kuo toliau, tuo labiau tampa aktualesnė, kadangi vis daugiau paslaugų bei veiklos procesų yra perkeliama į mobiliąją erdvę. Vartojamumas tampa vienas iš svarbesnių veiksnių, lemiančių internetinės sistemos išlikimo bei naudojimo perspektyvas. Tačiau išlieka atviras klausimas – ar kuriant internetinę sistemą tikslinga investuoti laiką bei resursus ir greta įprastinės vartotojo sąsajos vystyti dar ir mobiliesiems įrenginiams pritaikytą sąsają. Nagrinėjama sritis yra pakankamai nauja todėl tokio pobūdžio tyrimai arba bent jau jų rezultatai dar nėra plačiai paplitę bei skelbiami. Analizės metu buvo išnagrinėti vartojamumo tyrimo metodai bei mobiliųjų įrenginių internetinės vartojo sąsajos rekomendacijos. Pasitelkus dalį išanalizuotų metodų vartojamumo požiūriu buvo ištirtos dvi eksperimentinės tos pačios sistemos vartotojo sąsajos – mobilioji bei įprastinė, naudojamos mobiliajame įrenginyje. Eksperimentui reikalingos vartotojo sąsajos buvo realizuotos sukūrus bei įdiegus „naujienų tinklaraščio“ informacinę sistemą, turinčią tiek įprastinę tiek mobiliesiems įrenginiams pritaikytas vartotojo sąsajas. Vartojamumo tyrime buvo panaudoti trys vartojamumo tyrimo metodai, kurių pagalba sistemos vartojamumas tiriamas keliais aspektais: rekomendacijų laikymasis, sistemos techninės savybės, vartotojo sąveika su sistema. Gauti rezultatai leidžia daryti išvadą, jog kuriant internetinę...

So it is natural that more and mode services are served through mobile internet. As all regular applications, mobile web applications should be usable and user friendly. These aspects make a quite big influence on success of software. The main goal of this work is to make a usability research on web user interface for mobile devices. This research will show if there is a sense to make separate user interface for mobile devices when you are going to develop web system which will be also used by mobile devices users. The field of this work is web user interface for mobile devices and its usability. The object of this work is user interface usability research methodology.

The process of patient care relies on clinical data spread across specialized hospital departments. Powerful software is being designed to assimilate this disconnected patient data before treatment can be decided. However, these data are often presented to clinicians on interfaces that do not fit clinical workflows, leading to poor operational efficiency and increased patient safety risks. This project relies on ethnographic design methods to create evidence of clinician preferences pertaining to the presentation and collection of information on user interfaces in patient rooms. Using data gathered in clinical observation, a prototype interface was designed to enable doctors to conduct clinical tasks through a usable patient room interface. The prototype evaluation with doctors identified clinical tasks that are relevant in the patient room and provided insight into the perceived usability of such an interface. The evaluation sessions also elucidated on issues of patient-centeredness in technology design, effortless authentication and interface customizability.

In this work the main aspects were discussed that need to be evaluated by establishing graphical user interface. There were discussed some user interface languages and technologies such as XML, XUL, XIML, XSLT, CSS, XHTML, analyzed some used methods for automated user interface generation. On a basis of this analysis, the proper method was chosen to apply for generating of user interface using ODRES method results. On the next stadeges of the work it was designed and developed prototype of the GUI generation system. The main goals were to develop cross-platform user interface, using as mutch as possible simplyer technologies along with that securing constant design on different web browsers. Generation process operates using the GUI specification stored in the MS SQL database and converting it to XML and along with the XSLT files used as parser. After these files are opened using web browser, XML and XSLT code is processed to an XHTML code. The process of the user interface generation is flexible and alows user change GUI’s appearance on the fly adjusting it’s specification stored on the database or XSLT rooles as well. During this work were made some ot the modifications to the ODRES database: appended few more attributes, describing graphical elements characteristics and web form relations; added extra tables.
