This chapter presents the structure of an index which serves as support so allowing the development team to create the specification of the context of use document for the development of Web applications, bearing in mind characteristics of usability and accessibility, each point of the index being explained in detail. A correct preparation of this document ensures the quality of the developed Web applications. The international rules and standards related to the identification of the context of use have been taken into account. Also, the functionality limitations (sensorial, physical, or cognitive) which affect access to the Web are described, as well as the technological environment used by disabled people (assistive technologies or alternative browsers) to facilitate their access to the Web content. Therefore, following the developed specification of the context of use, usable and accessible Web applications with their corresponding benefits can be created.

As we know internet has become a very important factor in our day today life. It is a wide media for communication and exchange of ideas for people staying in any nook and corner of the world. We have proposed a system in which we are developing a speech interactive web application services. Our main aim is to provide these services to the special ones who are unable to make use of the current system so efficiently. In our proposed work we are mainly focusing on the WEB APPLICATIONS. Many a times the disabled people are unable to access internet, for them this system will help to download news, or even access their mails through speech. Our proposed system mainly deals with the ability to handle web applications along with the O.S, mouse and keyboard control through speech, so that they can be used by persons without the use of the hands to develop an interface between the computer and the user. In our proposal we have used SAPI .It provides commands to the main central application which is handled by the GUI. Thus we look forward to develop web application through speech interaction.

Using XML as the source format for authoring technical publications creates opportunities to develop tools that provide analysis, author guidance, and visualization. This case study describes two web applications that take advantage of the XML source format of documents. The applications provide a browser-based tool for technical writers and editors in a 100-person documentation department of a software company. Compared to desktop tools, the web applications are more convenient for users and less affected by hard-to-predict inconsistencies among users' computers. One application analyzes file dependencies and produces custom reports that facilitate reorganizing files. The other helps authors visualize their network of topics in their documentation sets. Both applications rely on the XQuery language and its RESTXQ web API. The visualization application also uses JavaScript, including the powerful jQuery and D3 libraries. After discussing what the applications do and why, this paper describes some architectural highlights, including how the different technologies fit together and exchange data.

Context: Widgets are reusable User Interfaces (UIs) components frequently delivered in Web applications.In the web application, widgets implement different interaction scenarios, such as buttons, menus, and text input.Problem: Tests are performed manually, so the cost associated with preparing and executing test cases is high.Objective: Automate the process of generating functional test cases for web applications, using intermediate artifacts of the web development process that structure widgets in the web application. The goal of this process is to ensure the quality of the software, reduce overall software lifecycle time and the costs associated with tests.Method:We elaborated a test generation strategy and implemented this strategy in a tool, Morpheus Web Testing. Morpheus Web Testing extracts widget information from Java Server Faces artifacts to generate test cases for JSF web applications. We conducted a case study for comparing Morpheus Web Testing with a state of the art tool (CrawlJax).Results: The results indicate evidence that the approach Morpheus Web Testing managed to reach greater code coverage compared to a CrawlJax.Conclusion: The achieved coverage values represent evidence that the results obtained from the proposed approach contribute to the process of automated test software engineering in the industry.

Web services are an emerging technology that has attracted much attention from both the research and the industry sectors in recent years. The exploitation of Web services as components in Web applications facilitates development and supports application interoperability, regardless of the programming language and platform used. However, existing Web services development standards do not take into account the fact that the provided content and the interactive functionality should be accessible to, and easily operable by, people with disabilities. This chapter presents a platform named myWebAccess, which provides a mechanism for the semi-automated “repair” of Web services' interaction characteristics in order to support the automatic generation of interface elements that conform to the de facto standard of the Web Content Accessibility Guidelines 2.0. myWebAccess enhances interaction quality for specific target user groups, including people with visual and motor disabilities, and supports the use of Web services on diverse platforms (e.g., mobile phones equipped with a browser). The Web developers can build their own design templates and the users of myWebAccess can create a personalized environment containing their favourite services. Thus, they can interact with them through interfaces appropriate to their specific individual characteristics.

This chapter at first surveys the Web technologies that can enable ubiquitous and pervasive multimedia communications over the Web and then reviews the challenges that are raised by their combination. In this context, the relevant HTML5 APIs and technologies provided for service adaptation are introduced and the MPEG-DASH, X3Dom, and WebRTC frameworks are discussed. What is envisaged for the future of mobile multimedia is that with the integration of these technologies one can shape a diversity of future pervasive and personalized cloud-based Web applications, where the client-server operations are obsolete. In particular, it is believed that in the future Web cloud-based Web applications will be able to communicate, stream, and transfer adaptive events and content to their clients, creating a fully collaborative and pervasive Web 3D environment.

Developing usable products becomes more and more important for software developers. Developing web applications it’s more challenging than developing desktop applications due to the various users that will interact with the final product. Satisfying users’ expectations becomes a very difficult task, as usability proves to be a very complex goal to achieve in the context of increased productivity targets in software engineering process. The present chapter focuses on the idea of rethinking the concept of usability moving from the traditional view of usability expressed in the internal characteristics of the product towards usability understood as deriving from the quality of interactions between humans, their work and the web design product. Usability is not only an add-on or a final result in the design process but it is embedded as a main concern within the design process itself. In order to build usable products, a great attention should be oriented to users and their needs, and this can be a very challenging task for software developer teams. In this chapter we will describe an interdisciplinary approach, based on applying social sciences techniques and methods that can be helpful in overcoming the difficulties in understanding the users. We will provide a short description of the proposed methods, a guide in applying these methods and a framework that integrates each of the proposed methods into the corresponding step of the web product development life cycle. The chapter ends with the presentation of two case studies showing the applicability of the proposed solution in real design contexts.

This chapter is devoted to the application of Web-based multimedia tools as a complement to traditional e-learning resources to improve the quality of teaching in two senses: adapting lesson contents to improving the understanding and increasing the motivation of the students. The authors present a set of practical tools that have achieved successful results in their courses and that, together, provide a more proactive teaching methodology based on interactive and mobile learning materials. These tools can be divided into two main groups: simulations and interactive videos, directly related to the process of studying, and quizzes and questionnaires, useful to adapt the teaching to the objective comprehension level. In addition, the authors point out the advantages of providing the students with more familiar multimedia materials suitable for being transported and consulted in mobile devices. A basic point of this methodology is that all these resources are available through a Web-based interface, so that the interaction does not depend on the physical presence of the students. Finally, the authors must point out that with their methodology they are focused on monitoring learning, which is achieved directly with online questionnaires, but they have also performed resource monitoring, in terms of degree of satisfaction and practical use. This is achieved, in this case, through the use of surveys and from the analysis of the statistics provided by the Web-based application.

Ontology is the core component in Semantic Web applications. The employment of an ontology building method affects the quality of ontology and the applicability of ontology language. A weighted classification approach for ontology building guidelines is presented in this chapter. The evaluation criteria are based on an existing classification scheme of a semiotic framework for evaluating the quality of conceptual models. A sample of Web-based ontology building method guidelines is evaluated in general and experimented with using data from a case study in particular. Directions for further refinement of ontology building methods are discussed.

Web authoring is the process of developing Web pages. The Web development process requires you to use software to create functional pages that will work on the Internet. Adding Web functionality is creating specific components within a Web page that do something. Adding links, rollover graphics, and interactive multimedia items to a Web page creates are examples of enhanced functionality. This chapter demonstrates Web based authoring techniques using Macromedia Dreamweaver. The focus is on adding Web functions to pages generated from Macromedia Fireworks and to overview creating Web pages from scratch using Dreamweaver. Dreamweaver and Fireworks are professional Web applications. Using professional Web software will benefit you tremendously. There are other ways to create Web pages using applications not specifically made to create Web pages. These applications include Microsoft Word and Microsoft PowerPoint. The use of Microsoft applications for Web page development is not covered in this chapter. However, I do provide steps on how to use these applications for Web page authoring within the appendix of this text. If you feel that you are more comfortable using the Microsoft applications or the Macromedia applications simply aren’t available to you yet, follow the same process for Web page conceptualization and content creation and use the programs available to you. You should try to get Web page development skills using Macromedia Dreamweaver because it helps you expand your software skills outside of basic office applications. The ability to create a Web page using professional Web development software is important to building a high-end computer skills set. The main objectives of this chapter are to get you involved in some technical processes that you’ll need to create the Web portfolio. Focus will be on guiding you through opening your sliced pages, adding links, using tables, creating pop up windows for content and using layers and timelines for dynamic HTML. The coverage will not try to provide a complete tutorial set for Macromedia Dreamweaver, but will highlight essential techniques. Along the way you will get pieces of hand coded action scripts and JavaScripts. You can decide which pieces you want to use in your own Web portfolio pages. The techniques provided are a concentrated workflow for creating Web pages. Let us begin to explore Web page authoring.

The consistent modeling of quality requirements for Web sites and applications at different stages of the life cycle is still a challenge to most Web engineering researchers and practitioners. In the present chapter, we propose an integrated approach to specify quality requirements to Web sites and applications. By extending the ISO 9126-1 quality views characteristics, we discuss how to model internal, external quality, and quality in use views taking into account not only the software features, but also the own characteristics of Web applications. Particularly, we thoroughly analyze the modeling of the content characteristic for evaluating the quality of information–so critical for the whole Web application eras. The resulting model represents a first step towards a multi-dimensional integrated approach to evaluate Web sites at different lifecycle stages.
