The concept of brand nowadays goes beyond the simple logo printed or displayed on a product or service. Branding is an important element for companies, and the communication channels used to deliver brand messages play a fundamental role. The advancement and innovation in web technologies made web communication artefacts crucial channels for companies and a key aspect of these artefacts is their usability. In this project a re-design process has been carried on the “Iliad Italia S.p.A.” corporate website from scratch, introducing innovative approaches such as user-centered design and value-based design. The developed website has been then used to perform an innovative comparative study aiming of verifying whether or not web usability affects brand perception. Adopting two different innovative procedures, brand perception has been measured on test subjects after using the old website and the new one. Analyzing the gathered data, a visible correlation has been found between usability and brand perception, indeed, using a website with higher usability resulted in a higher brand perception and the usage of a website with lower usability resulted in a decrease in brand perception in test subjects. The project introduced innovative research tools and procedures in a real case scenario, illustrating how they can be adopted in the development of web-communication artefact in companies, moving web development and marketing a step closer each other. / Il concetto di brand oggi va oltre il semplice logo stampato o esposto su un prodotto o servizio. Il branding è un elemento importante per le aziende, e i canali di comunicazione utilizzati per veicolare i messaggi del brand giocano un ruolo fondamentale. Il progresso e l'innovazione nelle tecnologie web hanno reso gli artefatti di comunicazione web cruciali per le aziende, e un aspetto chiave di questi artefatti è la loro usabilità. In questo progetto è stato portato avanti un processo di re-design del sito web aziendale di "Iliad Italia S.p.A." partendo da zero, introducendo approcci innovativi come lo user-centered design e il value-based design. Il sito web sviluppato è stato poi utilizzato per effettuare uno studio comparativo innovativo volto a verificare se l'usabilità di un sito web influisce o meno sulla percezione del brand negli utenti. Adottando due diverse procedure innovative, è stata misurata la percezione del brand successivamente all'uso del vecchio e del nuovo sito web. Analizzando i dati raccolti, è stata trovata una visibile correlazione tra usabilità e percezione del brand, infatti, l'utilizzo di un sito web con una maggiore usabilità ha portato a una maggiore percezione del brand e l'utilizzo di un sito web con una minore usabilità ha portato a una diminuzione della percezione del brand nei soggetti del test. Il progetto ha introdotto strumenti di ricerca e procedure innovative in uno scenario di uso reale, illustrando come questi strumenti e procedure possono essere adottate nello sviluppo di artefatti di comunicazione web nelle aziende, avvicinando lo sviluppo web al marketing. / Begreppet märke går idag utöver den enkla logotypen som skrivs ut eller visas på en produkt eller tjänst. Varumärke är ett viktigt inslag för företag, och kommunikationskanalerna som används för att leverera varumärkesmeddelanden spelar en grundläggande roll. Utvecklingen och innovationen inom webbteknologier gjorde att webbkommunikationsföremål är viktiga kanaler för företag och en viktig aspekt av dessa föremål är deras användbarhet. I detta projekt har en ny designprocess genomförts på "Iliad Italia S.p.A." företagets webbplats från grunden och introducerar innovativa metoder som användarcentrerad design och värdebaserad design. Den utvecklade webbplatsen har sedan använts för att utföra en innovativ jämförande studie som syftar till att verifiera om webbanvändbarhet påverkar varumärkesuppfattningen eller inte. Antagande av två olika innovativa förfaranden, varumärkesuppfattning efter användningen av den gamla och nya webbplatsen har mäts på testämnen. Genom att analysera de samlade uppgifterna har en synlig korrelation hittats mellan användbarhet och varumärkesuppfattning. Att använda en webbplats med högre användbarhet resulterade faktiskt i en högre varumärkesuppfattning och användningen av en webbplats med lägre användbarhet resulterade i en minskning av varumärkesuppfattningen i testpersoner. Projektet introducerade innovativa forskningsverktyg och förfaranden i ett verkligt fallsscenario, som illustrerar hur de kan användas för att utveckla webbkommunikationsartiklar i företag, flytta webbutveckling och marknadsföring ett steg närmare.

Researchers in the area of web usability dwell on the importance of simplicity in a website design so that users can achieve a specific task with effectiveness, efficiency and satisfaction. If a banking website misses one of these characteristics of usability users may get lost in the middle of the website or become frustrated and “will seek information elsewhere”. This study assesses what are the main issues behind the current banking websites through a questionnaire with 74 participants the result of this questionnaire shows that there are still unsolved problems in the current banking websites that impacts the quality of use. This study performs a thorough theoretical study to find out more about the subject understudy and by combining together with qualitative interviews; the study comes up with a proposed solution to improve banking websites’ usability – by implementing a user-centered design. / Program: Masterutbildning i Informatik

Web developers are confronted with evaluating the usability of Web interfaces. Automatic Web usability evaluation tools are available, but they are limited in the types of problems they can handle. Tool support for manual usability evaluation is needed. Accordingly, this research focuses on developing a tool for supporting manual processes in Heuristic Evaluation inspection. The research was conveyed in three phases. First, an observational study was conducted in order to characterize the inspection process in Heuristic Evaluation. The videos of evaluators applying a Heuristic Evaluation on a non-interactive, paper-based Web interface were analyzed to dissect the inspection process. Second, based on the study, a tool for annotating Web interfaces when applying Heuristic Evaluations was developed. Finally, a survey is conducted to evaluate the tool and learn the role of annotations in inspection. Recommendations for improving the use of annotations in problem reporting are outlined. Overall, users were satisfied with the tool. The goal of this research, designing and developing an inspection tool, is achieved.

A constante evolução da Web tem se mostrado como um fenômeno mundial que rapidamente precisa responder aos diversos segmentos da sociedade atual, com websites e aplicativos de compras, governo, bancos, entretenimento e outros. Nesse contexto, é necessário que o conteúdo Web possibilite acesso aos mais diferentes perfis de usuários, independentemente de suas deficiências ou necessidades especiais. Um outro fenômeno mundial é o envelhecimento da população. Os usuários senescentes (pessoas que estão em processo de envelhecimento, o qual acarreta declínio físico e mental gradual, ocorrendo geralmente nos indivíduos a partir de 60 anos de idade), apresentam algumas de suas capacidades reduzidas e, encontram, naturalmente, barreiras ao interagir com os serviços e conteúdos disponibilizados na Web. Essa população tem apresentado um índice de crescimento demográfico grande neste século em relação ao que se via nas gerações passadas. Apesar das exigências de legislação específica, recomendações e diretrizes que auxiliam o desenvolvimento de conteúdo acessível e usável, ainda há muitos problemas de acessibilidade e usabilidade que precisam ser resolvidos, diante do rápido avanço tecnológico observado nos recursos da Web atual. Em especial, observa-se pouca atenção às dificuldades que usuários senescentes possuem, pois a maioria de websites são projetados considerando como público-alvo, pessoas mais jovens e especializadas, muitas vezes, treinadas para interagir nos websites. Portanto, é relevante um apoio para avaliação das páginas Web, visando atender as necessidades dos usuários senescentes. A proposta deste projeto foi desenvolver um apoio para a avaliação de acessibilidade e usabilidade na Web, considerando-se o perfil dos senescentes, com vistas a proporcionar um feedback objetivo, aos desenvolvedores e especialistas. Esse apoio foi elaborado por meio de um Checklist que foi desenvolvido, com base em procedimentos científicos, e análises realizadas, sobre sua aplicação. / The constant evolution of the Web has proven to be a worldwide phenomenon that quickly needs to address the various segments of current society (websites and web applications, government, banks, entertainment and others). In this context, it is necessary that the Web content provides the possibility of access to the different user profiles, regardless of their disabilities or special needs. Another worldwide phenomenon is the aging population. The senescent users (people who are in the aging process, which leads to gradual physical and mental decline, usually occurring in individuals from the age of 60) have some of their capacities limited and they face barriers to interact with services and content available on the Web. This population has shown a high growth rate in this century in comparison to what was observed in past generations. Despite of the demands for specific legislation, recommendations and guidelines that assist the development of content accessible and usable, there are still many problems of accessibility and usability that need to be solved, given the rapid technological advances seen in the current Web resources. In particular, there is little attention to the difficulties that senescent users have, given that most websites are designed considering target audience that usually is composed of young people and specialists, often trained to interact on websites. Therefore, it is important to support evaluation of Web pages, to meet the requirements of senescent users. The purpose of this project is to develop a support for the evaluation of web accessibility and usability, focusing on the older people, in order to provide clear feedback to developers and experts. This support was prepared by a Checklist that was developed based on scientific procedures, and analyzes on its application.

This diploma thesis analyses the phenomenon of adapting e-shops selling electronics and computers to the Generation Y in the terms of website usability. The theoretical part is divided into three main chapters. The first chapter describes a consumer behavior, shopping behavior and the difference between shopping behavior in physical stores and their cyberspace counterparts. The following chapter deals with the Generation Y and its characteristics. The last part describes the web usability itself, its common flaws in usability and the topic of web usability testing. The practical part is dedicated to a web usability testing on selected e-shops. The testing itself  was conducted by the user testing method, where all the tested subjects belonged to the Generation Y. A questionnaire and a guided interview were also used to gather information for the study. The survey revealed many elemental flaws in the terms of  web usability of studied samples and presented suggestions how to correct them. A big problem was found mainly in the design structure of the sites. Users were under constant advertisement pressure which has neutral or even negative effect on the Generation Y.

Title of dissertation: Web Audit Methodology A web site is often the first point of contact between the user and another person or company or organization, so that in the electronic world, a web site is like a calling card. Ideally therefore, a web site should load relatively quickly to prevent the user from looking elsewhere even before the web site has opened. Also, the web site should have a pleasant design to make it user-friendly, it should display helpful content, be widely accessible and, last but not least, fulfil the aims for which it was created. It is the responsibility of web site designers, programmers and creators to ensure that web sites fulfil their function. A web site audit - either during or after its construction - is the best way of checking that all factors relating to access, use, technical processes and other criteria function correctly. There are many audit companies on the market today, each of them offering the customer its own particular perspective, evaluation according to different criteria and audit conducted using various methods. Therefore, the first part of this work contains an overview of different perspectives used to assess the quality of web sites, as well as designers and the specific methodology they apply during web site audits. The second part of this work...

(in English): This thesis is dedicated to the analysis and evaluation of applied information architecture of two selected digital libraries - Manuscriptorium and Kramerius of the National Digital Library. Information architecture is one of several interconnected web design disciplines. For designing purposes, information architecture can be defined as a complex of elements and principles. Analysis and evaluation of the existing information architecture depends on its integration into the web sites context. The thesis contains theoretical part with definition of information architecture, its elements and principles of design. It describes evaluation methods of information architecture as a combination of qualitative and quantitative elements of web sites. Information architecture of digital libraries often means architecture of the system. The thesis contains a definition of a digital library and explains focus on access application. Testing of web usability is the best way of testing the information architecture of digital libraries. It enables to test information architecture from user's point of view. The conclusion provide results of the usability tests.
