A universalização do acesso ao conteúdo disponibilizado em sistemas Web tem se tornado crucial para que todas as pessoas, independente de deficiências ou de outras restrições possam ter acesso a ele. Diversos estudos indicam que, apesar da instituição de leis federais sobre acessibilidade para conteúdo Web em diversos países, muitos sítios ainda apresentam problemas. A falta de conscientização das pessoas envolvidas em projetos de desenvolvimento Web sobre a acessibilidade e a não utilização de técnicas adequadas para desenvolvimento de aplicações têm um impacto considerável sobre a acessibilidade. Levantamentos foram realizados com o objetivo de identificar características dos desenvolvedores sobre o conhecimento e uso de técnicas para acessibilidade. Entretanto, os estudos realizados investigaram somente o uso de um conjunto restrito de técnicas e, além disso, também não investigaram a correlação entre as respostas obtidas pelos participantes e o nível de acessibilidade das páginas desenvolvidas por eles. Neste trabalho, propõe-se efetuar um levantamento sobre a percepção de acessibilidade e uso de técnicas para desenvolvimento de sistemas Web considerando acessibilidade com pessoas envolvidas em projetos de desenvolvimento Web no Brasil de diferentes áreas de atuação. Este levantamento foi acompanhado de avaliações de acessibilidade automatizadas com uso de métricas sobre sítios desenvolvidos pelos participantes, para verificar a influência dos fatores investigados na acessibilidade dos sítios e na percepção de acessibilidade dos participantes. O levantamento realizado contou com a participação de 613 participantes de todo o Brasil. Os resultados indicaram que no Brasil a percepção da acessibilidade por pessoas que participam de projetos de desenvolvimento Web ainda é bastante limitada. Mais do que promover o treinamento das pessoas envolvidas em projetos sobre questões técnicas, é necessário promover maior conscientização sobre a acessibilidade e sobre os problemas que pessoas com diferentes restrições e habilidades enfrentam ao utilizar a Web. / Universal access to content in Web based systems is an essential aspect to enable everyone to have access to it, regardless of disabilities or any other restrictions. Several studies indicate that, although federal legislation regarding to Web accessibility have been promulgated in many countries, accessibility is still an issue for many Web sites. The limited awareness of accessibility by people involved in Web development and the lack of appropriate use of development techniques in the development of applications have a deep impact on accessibility. A few surveys have been carried out to identify the main characteristics of Web developers regarding accessibility concepts and techniques for accessibility. However, the studies reported up to this date have only investigated the use of a restricted set of techniques by developers. Besides, they have not addressed the analysis of the correlation between the answers provided by the subjects and the accessibility level of their Web pages. The proposal of the work presented in this master\'s thesis is the development of a survey on the accessibility awareness and on the use of techniques for accessibility by people involved in the development of Web based systems. Automatic metric based accessibility evaluations on the Web sites developed by the subjects were carried out to support the investigation of the impacts that the issues investigated have on the Web pages accessibility and on the accessibility awareness. The survey was answered by 613 subjects from all Brazilian states. The results show that in Brazil the accessibility awareness is still very limited. Training people involved in Web projects on technical issues alone is not enough. It is necessary to promote a wider awareness of accessibility and of the problems people with different restrictions and abilities deal with when using the Web

Fem till åtta procent av Sveriges befolkning är diagnostiserade med dyslexi och nästan tjugofem procent har läs- och skrivsvårigheter. Nittiofyra procent av Sveriges befolkning använder internet inom alla områden i vardagen, allt från utbildning och arbete till att läsa nyhetstidningar och söka information i uppslagsverk.Från tidigare forskning är det känt att kunskap om att tillgänglighet på webben är ett problem för personer med dyslexi, men inte tillräckligt många människor tar ansvar för att det ska förändras. Vår värld går från analog till digital i dagens digitalisering, därför är det viktigt att göra digitalt innehåll tillgängligt för alla typer av människor, oavsett funktionsnedsättning eller inte.Denna studie syftar till att få en djupare förståelse, genom ett frågeformulär, angående hur människor med dyslexi och/eller läs och skrivsvårigheter upplever tillgängligheten på webben idag. Studien identifierar vilka hinder dessa människor står inför när de försöker få ta del av information på webben och analyserar hur de identifierade och analyserade hindren kan användas för att skapa en ”easy-to-use-and-implement” verktygslåda. För att validera om verktygslådan hade kunnat användas på webbplatser för att anpassa hur informationen visas och därmed öka tillgängligheten, genomfördes ett användbarhetstest. När användaren inkluderas tidigt i processen är det möjligt att förbättra prototypen innan den släpps live och görs tillgänglig för utvecklare. Användbarhetstestet genomfördes i form av ett Think Aloud protocol och syftade till att koppla samman både slutanvändarens tankar med beteendet under tiden verktygslådan användes.Resultatet av studien visar att majoriteten av deltagarna inte tycker att speciellt många webbplatser idag är anpassade för personer med dyslexi. De tycker också att webbplatser borde erbjuda möjlighet att anpassa hur innehållet visas på webbsidor utan att behöva använda webbläsartillägg. Resultatet visar på att prototypen innehåller funktionalitet som minskar dessa hinder för personer med dyslexi. Man kan också se att den tidigare forskning av färger, teckensnitt, textstorlek och radavstånd är fyra av sex kategorier som deltagarna i denna studien anger som de största hindren när man försöker ta del av information på webbplatser idag. Vad deltagarna också upplevde, var att verktygsfältet hade kunnat innehålla fler val inom de utvalda kategorierna för att anpassa verktygsfältet för den enskilda personen istället för en stor grupp människor. Det är också ett av förslagen för framtida forskning. / Five to eight percent of Sweden's population is diagnosed with dyslexia and almost twenty-five percent experience reading and writing difficulties. Ninety-four percent of Sweden's population uses the internet in all areas of life, from education and work to reading newspapers and gathering information from encyclopedias. From previous research, it is known that web accessibility is a problem for people with dyslexia, but not enough people take action. The world goes from analog to digital in today's digitalization, therefore it is important to make the digital content available and accessible for all kinds of people, regardless of disability or not.This study aims to get a deeper understanding, through a questionnaire, of how people with dyslexia and/or reading and writing disabilities experience the accessibility on websites today. The study identifies what obstacles these people face when they try to access information on websites and how the identified and analyzed obstacles could be used to create an easy-to-use-and-implement toolbar to help people overcome these obstacles.. To validate if the toolbar could be used on websites to customize how the information is displayed and thereby access the information easier, a usability test was conducted. When the user is included early in the process, it is possible to improve the prototype before it is released live and available for developers to implement on their websites. The usability test was conducted through a Think Aloud protocol and aimed to connect the end-users thoughts with their behavior while using the component. The result of the study shows that the majority of the participants do not think that many websites today are adapted for people with dyslexia and think websites should offer the ability to customize how the content is displayed on web pages without having to use browser extensions. The result also shows that the easy-to-use-and-implement toolbar includes functionality that will decrease these obstacles for people with dyslexia. You can also see that the previous research on colors, font style, font size, and line spacing is four of six categories the participants in this study see, as the biggest obstacles when they try to access information on websites today. What they also experienced was that the toolbar should include more choices within these categories to customize the toolbar for the individual person instead of a large group of people, which also is one of the suggestions for future research.

With the rise of e-learning and recent legislations of the European Union enforcing conformance to Web Content Accessibility Guidelines 2.0 for web applications of public sector bodies, the issue of identifying and solving web accessibility issues in e-learning applications is more relevant than ever. This thesis is based on a case study of a publisher of course literature whose intention is to improve the accessibility of their e-learning applications. The thesis contains a theoretical foundation on disabilities, e-learning and web accessibility including assistive technologies, the web accessibility guidelines WCAG 2.0 and the web accessibility evaluation method WCAG-EM. This theory is used for developing solutions to accessibility issues found in the e-learning applications and comparing accessibility with e-learning theory. The results are presented as concrete examples to be useful for developers of e-learning applications. It was found that there exist a few instances where accessibility and e-learning contradict each other, but the solutions to accessibility problems are most often not affected by the learning premise of the applications.

I takt med införandet av webbtillgänglighetsdirektivet har fenomenet webb­tillgänglighet aktualiserats. Begreppet tillgänglighet används inom webbutveckling för att be­skriva i vilken mån en produkt, en service eller en miljö är användbar och navigerbar för per­soner med särskilda behov eller funktionsnedsättningar. Webbtillgänglighet innebär strävanden efter att göra det enklare för sådana personer att uppfatta, navigera, förstå och bidra till webben (Kulkarni 2019). Den här uppsatsen undersöker vad arbetsverksamma inom webbutveckling anser krävs för att införa tillgänglighet på webben. Syftet är att nå en ökad förståelse av vad arbetsverksamma anser krävs för att införa tillgänglighet på webben samt vilka hinder och vil­ken problematik de stöter på i processen. Forskningsfrågan är ”vad tycker webbutvecklare och interaktionsdesigners krävs för att skapa tillgäng­lighet på webben?”. Undersökningen är utformad som en kvalitativ, deskriptiv fallstudie. Datainsamlingen utförs genom semistruktu­rerade intervjuer med konsulter hos IT-bolaget XLENT. Datan har tematiserats med hjälp av kodning och analyserats utifrån det teoretiska ramverket som används, nämligen aktivitetsteori (AT). Problem är bland annat att webtillgänglighet ofta prioriteras lågt hos beställare, svårig­heter att förklara fördelar och vikt av webbtillgänglighet samt begränsade resurser. Slutsatsen är att det som anses krävas är ökad kunskap och medvetenhet om webbtillgänglighet hos be­ställare och arbetsverksamma, fler incitament för att införa tillgänglighet, pragmatisk lagstift­ning, prioritering av tillgänglighet från början av ett projekt, mer samarbete med testpersoner samt fler färdigt inbyggda lösningar i webbläsare. / The web accessibility directive has made web accessibility as a phenomenon a current issue. The concept of accessibility is used in web development to describe to what extent a product, a service or an environment is usable and navigable for people with certain needs or disabilities. Web accessibility involves the goal of making it easier for such persons to perceive, navigate, understand and contribute to the web (Kulkarni 2019). This study examines what practitioners in web development think is required to initiate accessibility on the web. The pur­pose is to reach a greater insight into what practitioners think is required to initiate web acces­sibility and what obstacles and problems they encounter during the process. The research ques­tion is: “what do web developers and interaction designers think is required to initiate web accessibil­ity?”. The study is a qualitative, descriptive case study. The data collection is made through semi-structured interviews with consultants at the IT-company XLENT. The data has been the­matized through coding and has been analyzed based on the theoretical framework, namely activity theory (AT). Problems observed are, among others, that web accessibility often is a low priority among clients, difficulties in explaining advantages and the importance of web acces­sibility and limited resources. The conclusion is that what is considered required is increased knowledge and awareness among clients and practitioners, more incentives to initiating web accessibility, pragmatic legislation, that web accessibility is prioritized from the very beginning of a project, more cooperation with people with disabilities during the process and more ready-made solutions in browsers.

Purpose –Comparing the accessibility of e-commerce for General Merchandise, between major retailers and novelties, in the conformance of web accessibility guidelines, and the implementation of rich internet applications specifications. So that to figure out whether the differences exist between them, if so, what are the differences, and analyzing upcoming e-commerce and established e-commerce.  Method – The descriptive and quantitative case studies were used to evaluated 45 websites respectively from major retailers and novelties in General Merchandise of e-commerce, where sample websites were selected from Alexa’s rank lists. Then the WAVE tool, Accessibility Quantitative Metric (WAQM), and Fona assessment were applied for analyzing cases for representing the accessibilities and answering the research questions of purpose.  Findings – ARIA specifications as a kind of technological solution really had positive functions on web accessibility when only focusing on accessibility guidelines, because the novelty websites with less ARIA attributes resulting in lower accessibility levels generally, even though there were also many other elements that can affect accessibility.  Implications – In the main branch of General Merchandise, the degree of web accessibility in major retailer websites was better than that in novelties, which means as far as e-commerce is concerned, the accessibility of mature websites that had been established for a long time was contemporarily stronger than that of new websites with creative products.  Limitations – From the perspective of the sample, there were limitations in sample sources, size, websites languages, while in the technical aspect, the evaluation of dynamic contents just aims at keyboard navigation, and the tool of Fona assessment also had restrictions.

Digitalization in society is going fast and was accelerated further by the Covid-19 pandemic. By this, many people's everyday tasks were transferred to digital environments. This meant in Sweden that most new internet users in 2020 were people over the age of 75 and people with different types of disabilities. Due to this increase in digitalization and all these new internet users, accessibility online is a subject that has gained higher significance. Since September 2020, all Swedish municipalities' websites must be accessible by law. Municipalities have a great responsibility to make information and necessary services available to the public. The purpose of this study was to investigate how well municipalities succeed with their work with web accessibility as a consequence of the legislation in Sweden and identify where the municipalities meet concrete obstacles in order to comply with the law. The purpose was also to investigate how the work with web accessibility on municipal websites can be simplified, improved, or otherwise enabled for those who work with such issues in the municipalities. To fulfill the purpose, two research question was formed for the study: 1.     In the process of making municipalities’ websites accessible, which are the concrete obstacles that make the work difficult for those who work with such issues in the municipalities?   2.     How can the work with the accessibility of municipal websites be simplified, improved, or otherwise enabled for those who work with such issues in the municipalities? To answer the research questions, two methods were chosen, a web survey and in-depth interviews, which corresponds to a combination of a quantitative and a qualitative method. The web survey was sent out to all municipalities in Sweden with the focus to answer RQ1 and the in-depth interviews were conducted with two accessibility experts with the focus to answer RQ2. Several obstacles were identified relating to lack of resources, lack of competence, lack of understanding of the law and the interpretation of it, attitudes, and old technology. Solutions on how the work can be simplified for those who work with web accessibility were identified relating to attitudes, resources, competence, legislation, and consumer demands. The main conclusions were that even though a municipality comply fully with the law, it does not mean that the website is accessible for all users, hence the law is not comprehensive enough. It also shows that there are several aspects that makes it hard for the municipalities to comply with the law and that most of these aspects also are the areas that needs improvement for the work to be simplified for the municipalities.

As the web continues to evolve, so does our need for achieving an accessible web for people with disabilities. Content management systems (CMSs) have well observed accessibility problems with generated content, and in recent years, several features have been proposed in order to minimize or eliminate these problems. This study investigated CMSs in current use to find common accessibility problems and evaluated a set of features proposed by Acosta, T. et al. in 2018, targeting these problems. The study initially found a general lack of information, guidance and technical support provided by CMSs to editors promoting the generation of accessible content. The results indicate that even editors highly aware of accessibility may not be able to create accessible content due to the limitations of their systems. The study also received positive feedback towards the evaluated features from professionals, indicating that the features are of practical value and may help the editor by minimizing or eliminating common accessibility problems in content generated through CMSs. / Webben fortsätter att utvecklas, och det gör också vårt behov av att göra webben tillgänglig för personer med funktionshinder. Innehållshanteringssystem (CMS) har flera kända tillgänglighetsproblem med dess genererande innehåll och under de senaste åren så har ett antal tillgänglighetsfunktioner föreslagits för att minimera eller eliminera dessa problem. Den här studien undersökte CMS som används idag för att hitta vanliga tillgänglighetsproblem och evaluerade en samling av föreslagna funktioner av Acosta, T. et al. som riktade sig mot dessa problem. Studien fann i början en generell brist på information, vägledning och tekniskt stöd från CMS till redaktörer som främjar skapandet av tillgängligt innehåll. Resultaten visar att även redaktörer som är medvetna om tillgänglighet inte alltid har möjligheten att skapa tillgängligt innehåll på grund av begränsningarna i deras system. Studien fick också positiv återkoppling av de utvärderade funktionerna från yrkesverksamma inom området, vilket indikerar att funktionerna har ett praktiskt värde och kan hjälpa redaktören genom att minimera eller eliminera vanliga tillgänglighetsproblem i innehåll som skapats via CMS.

Was bedeutet Barrierefreiheit im Internet? Welche Elemente auf einer Website werden zur Barriere für Menschen mit Sehbehinderungen oder Blindheit? Was sind Barrieren für gehörlose Menschen und was sind Barrieren für körperlich eingeschränkte Menschen? Und wie können diese Barrieren erkannt und abgebaut werden? Welche Lösungsmöglichkeiten gibt es und mit welchem Aufwand sind diese umzusetzen? Die Arbeit zeigt am Beispiel einer Plattform für Studierende mit Behinderungen an der TU Dresden Barrieren im täglichen Umgang mit elektronischen Dienstleistungen für betroffene Nutzer auf. Dafür wird die Anwendung verschiedener anerkannter Evaluationsmethoden am Praxisobjekt demonstriert und mit echten Nutzer-Interviews ergänzt. Auf der Grundlage der erhobenen Daten wird das der Plattform zugrundeliegende Kontextszenario qualifiziert und erweitert und ein Redesign durchgeführt. Die erfolgreiche Anwendung und Umsetzung der Richtlinien für Barrierefreiheit und Gebrauchstauglichkeit wird anschließend dokumentiert und demonstriert.

Acessibilidade na Web tem como objetivo possibilitar que qualquer pessoa possa entender e interagir com o conteúdo de uma página Web, independente de deficiências ou outros fatores. Embora exista uma grande quantidade de trabalhos realizados na área, pode-se ainda perceber que pessoas com alguns tipos específicos de deficiências encontram mais dificuldades ao navegar na Web, como no caso dos usuários cegos. Com intuito de minimizar os problemas enfrentados por esses usuários cegos ao navegar na Web, foi proposta nesta tese uma abordagem que consiste em extrair automaticamente o conhecimento de navegação implícito na apresentação visual de uma página Web e alterar o design dessa navegação de uma maneira otimizada a esses usuários. Com esse objetivo, primeiramente foram estudados os trabalhos relacionados aos principais problemas enfrentados pelos usuários cegos ao interagir com a Web, assim como os conjuntos de diretrizes de acessibilidade e usabilidade específicos para minimizar esses problemas, fundamentados em um mapeamento sistemático conduzido sobre o tema. Após a identificação dos problemas e diretrizes, foi desenvolvido um classificador baseado no método Naïve Bayes, considerando-se três características comumente encontradas nos padrões de design de menus de navegação, com intuito de classificar automaticamente os links contidos nesta página em diferentes classes referentes às estruturas de navegação. Após desenvolvido, o método foi testado e avaliado em sites governamentais por meio de uma análise estatística, apresentando um boa taxa de acerto em suas classificações. Com base nas dificuldades encontradas na primeira etapa de pesquisa, foi proposto um modelo de interface próprio aos usuários cegos que utilizam a Web com auxílio de um leitor de tela. Com base no classificador desenvolvido, foi proposta uma abordagem para automaticamente transformar os links de navegação classificados pelo método, em um padrão de navegação otimizado aos leitores de tela. Como prova de conceito, foi realizada uma extração semiautomática de conteúdo das páginas Web, com intuito de transformar esse conteúdo para o novo modelo de interface proposto. Nesse contexto, foi desenvolvido um protótipo de mecanismo de apoio, denominado NavAux. Esse protótipo foi avaliado através de um percurso cognitivo. Para isso, foram definidas algumas tarefas e a exploração da interface foi realizada com apoio do leitor de tela JAWS. Os resultados apresentaram indícios de que a abordagem proposta pode ser considerada uma alternativa viável para minimizar os problemas de acessibilidade enfrentados pelos usuários cegos ao navegar na Web. / Web Accessibility aims to enable that any individual may understand and interact with a Web page content, regardless of disabilities or other factors. Although there is a large number of research studies in this area, it can be noted individuals with some specific types of disabilities find it more difficulty browsing the Web, such as those who are blind. In order to minimize the problems faced by blind users when browsing the Web, the study reported in this thesis proposed an approach which consists in automatically extracting the navigation knowledge implicit in the visual presentation of a Web page and changing this navigation design to an optimized way to those users. For this purpose, the research started with a review of the papers related to the main problems faced by blind users when interacting to the Web, as well as the specific sets of accessibility and usability guidelines to minimize these problems, based on a systematic mapping study conducted on the topic. After identifying the problems and guidelines, the next step involved the development of a classifier based on the Naïve Bayes methods, considering three features commonly found in the design patterns of navigation menus, in order to automatically classify the links contained on each page into different classes relating to the navigation structures. After developed, the method was tested and assessed in governmental websites through an statistical analysis, showing a good success rate in its classifications. Based on the difficulties encountered during the first step of the research, the study proposed an interface model tailored to blind users who use the Web with the help of a screen reader. Based on the developed classifier, the study proposed an approach to automatically transform the browsing links classified by the method into an optimized navigation standard to screen readers. As a proof of concept, the following step involved a semi-automatic extraction of Web pages content, in order to transform this content to a new proposed interface model. In this context, was developed a prototype of the mechanism, named NavAux. This prototype was evaluated through a cognitive walkthrough. To this, were defined some tasks and the interface operation was performed with support of the JAWS screen reader. The results presented signs that the proposed approach can be considered a viable alternative to minimize the accessibility problems faced by blind users when browsing the Web.

A diversificação nas formas de acesso à Web, alavancada pelo crescente uso de dispositivos ubíquos, principalmente smartphones e tablets, tem motivado o desenvolvimento de métodos para adaptação do conteúdo disponível na Web, dado que grande parte do conteúdo não foi projetado para ser acessado nesse novo contexto. O conteúdo Web é composto por diversos elementos que, em geral, fornecem interatividade aos usuários. Alguns destes elementos, tais como menus, são responsáveis por auxiliar a navegação no site, ajudando na localização e acesso das informações que por ventura o usuário esteja procurando. No entanto, muitos dos menus disponíveis na Web não foram desenvolvidos de uma forma acessível e nem suportam a interação em dispositivos, criando dificuldades que impedem os usuários interagirem satisfatoriamente com esses elementos. Além da diversificação de modos de acesso, existe também a diversificação do perfil de usuários que fazem uso dos recursos da Web. Alguns desses usuários encontram barreiras que tendem a dificultar ou limitar seu acesso às aplicações e conteúdos Web em geral. Nesse sentindo, este trabalho teve como objetivo principal abordar o problema de adaptação de conteúdo Web para dispositivos móveis, com foco nos menus, fornecendo uma solução personalizada de acordo com as preferências do usuário, a fim de que as barreiras de interação fossem reduzidas ou eliminadas. Inicialmente estudou-se os diferentes padrões de menus, bem como as diretrizes de acessibilidade e usabilidade para criação de menus acessíveis. A partir desses estudos, foi desenvolvido uma metamodelo que deu origem a linguagem AMenu, contendo todos os detalhes técnicos sobre a acessibilidade e usabilidade. Em seguida, foi desenvolvida a ferramenta AMeG, para validar a linguagem AMenu. Com base na avaliação da linguagem, foi desenvolvido o mecanismo de adaptação, que faz uso da linguagem AMenu para geração dos menus acessíveis e adaptados para dispositivos móveis. Finalmente, um estudo de caso com usuários idosos foi conduzido, a fim de comparar os menus gerados pelo mecanismo em relação aos menus originais. Os resultados obtidos apontam um melhor desempenho na interação com os menus gerados pelo mecanismo, uma vez que os participantes obtiveram uma redução de 54% no tempo de realização das tarefas e cometeram 82% menos erros. Por outro lado, os resultados apontam que todos os participantes responderam melhor à abordagem de adaptação desenvolvida neste estudo, uma vez que eles conseguiram concluir com sucesso todas as tarefas definidas para o estudo. / The diversity of means to use the Internet, ensured by the growing upcoming of ubiquitous devices such as tablets and smartphones, has promoted research on adaptation of the content that used to be mostly targeted only to desktop platform into this new context now known as the mobile devices. Some of the elements such as the menus are designed to facilitate the usage of the website once they help at finding and using the information that the user looks for. However, most of the menus available on websites do not apply the mobile devices, nor provide users with interaction, which nearly disables the interaction with the mentioned devices. There yet must be added the profile diversity of the web content users. Some of these users, such as elderly people, find limitations that tend to hamper their access to web content on the mobile devices, once aging commonly represents both physical (visual, hearing and motor abilities) and cognitive (attention, memory and reasoning issues) impairment that directly interferes on the usage of the computing devices that do not portray adjustments to such audience profile. This paper aims at investigating the issues related to the adaptation of web contents into the mobile devices. We focused on the menus in order to reduce or eliminate the limitations elderly people could find while using the mobile devices. We initially analyzed different patterns and structure of menus, as well as the guidelines upon accessibility and usability involved in the menus designing process. Based on this analysis, we developed a metamodel that originated the AMenu language, in which all technical data upon accessibility and usability involved in the menus designing process was included. Then, we developed the AMeG tool in order to assess the language created under the development perspective. Based on this assessment, we developed of an adaption mechanism that uses the AMenu language to generate menus adapted to the mobile devices. We then run a study case with elderly people in order to assess the menus generated by the mechanism, based on the comparison with the original ones. The results demonstrated that the participants had a better performance in the interaction while using the menus generated by the mechanism rather than the original ones, since they spent 54% less time performing tasks and made 82% less mistakes compared to the original menus. We also verified a quitting average of 33% among the participants while performing the assigned tasks using the original menus. On the other hand, the results point out that all participants responded better to the approach developed in this study as they all managed to successfully finish all the assigned tasks.
