Recent advances in mobile computing have spawned a very heterogeneous environment of mobile devices, which is reflected by the presence of the devices’ different capabilities. This chapter focuses on handling this device heterogeneity in the context of content adaptation of mobile services so that generic content can be provided to any device in the heterogeneity spectrum. We present an approach that enables mobile services to adapt its content provision to a mobile device by considering the device’s content provision capabilities. Those capabilities encompass both the communication channels for content delivery and the capabilities to present content to the user. Our approach is designed as a service platform that implements a content adaptation procedure for Web-based mobile services by utilizing device capability databases and generic page transformation. This approach enables mobile devices to visualize any generic content device specifically on their integrated browsers.


While HTML will continue to be used to develop Web content, how to effectively and efficiently transform HTML-based content automatically into formats suitable for mobile devices remains a challenge. In this paper, we introduce a concept of coherence set and propose an algorithm to automatically identify and detect coherence sets based on quantified similarity between adjacent presentation groups. Experimental results demonstrate that our method enhances Web content analysis and adaptation on the mobile Internet.

Most Web pages are designed with desktop platform access in mind, but with the proliferation of mobile devices such as Personal Digital Assistants (PDAs) and mobile phones, accessing Web pages through a variety of devices without proper content adaptation can result in an aesthetically unpleasant, un-navigable and, in most cases, unsatisfying experience. This article provides an overview of approaches in Web content adaptation framework and techniques being developed to extend the Web application access to non-desktop platforms. After describing general adaptation techniques, the article focuses particularly on the adaptation requirements of learning systems, especially when they are accessed through mobile devices.

The mobile environment presents numerous challenges to users and developers alike. Ideally, mobile content should be designed to enhance a user's experience rather than simply serve up the same content originally designed for other platforms. This chapter presents a study of techniques for “content adaptation”, the process of reformatting content and displaying it optimized for a mobile device. Adaptation techniques consist of a varied number of mechanisms by which content is adapted into a format more “friendly” to mobile devices. The idea of “friendly” can range from simple accessibility requirements to a dynamic redesign. Included in this discussion is a summary of the advantages and disadvantages of current techniques. Examples of different techniques are presented and illustrated along with the system framework necessary to implement them.

Content adaptation is defined as the process of selection, generation, or modification of content which include text, images, audio, video, navigation, interaction, any object within a Web page, and associate service agreement (Forte, Claudino, de Souza, do Prado, & Santana, 2007) to suit user’s context (TellaSonera, 2004). With the proliferation of mobile devices such as personal digital assistants (PDA) and smart mobile phones which have the capability of accessing the Internet anytime and anywhere, there is an increasing demand for content adaptation to provide these devices with appropriate content that is aesthetically pleasant, easy to navigate, and achieve satisfying user experiences. This article first provides an overview of frameworks and techniques in Web content adaptation that are being developed to extend Web applications to non-desktop platforms. After describing general adaptation techniques, this article focuses particularly on the adaptation requirements for e-learning systems, especially when they are accessed through mobile devices.
