Who should read this book?

Whether you're completely new to web design, a seasoned pro looking for inspiration, or a developer wanting to improve your sites' aesthetics, there's something for everyone here.

How? Because instead of trying to cover every possible area of creating a web site, we've focused purely on the design stage; that is, everything that happens before a single line of code is written.

However, great design is more than just aesthetics. Long before we open our graphics program of choice, we'll be conducting research, dealing with clients, responding to briefs, sketching out sitemaps, planning information architecture, moving from doodles to diagrams, exploring different ways of interactivity, and building upon design traditions.

But ultimately, you'll be finding out how to create web sites that look drop-dead gorgeous.

For a period of 6 years, the course retention rate for Marylhurst University's (MU) online courses was 91%, which is within four percentage points of its on-campus course retention rate (Schreck, 2001). This grounded theory, web-based, research study aims to explicate the reasons why MU online students complete courses at high rates and develop this understanding into an online student retention model. A grounded theory approach was used to conduct this study, which is described by Creswell (2002) as, "a systematic, qualitative procedure used to generate a theory that explains, at a broad conceptual level, a process, an action, or interaction about a substantive topic" (p. 439).

University websites hold considerable power for reaching prospective students via a cost-effective means as many view the Internet as the great equalizer among institutions. Unlike traditional forms of marketing, the quality of a website does not have to be limited by university size or budget as the price of accessing the medium and distributing the message can be equal for all. Therefore, in terms of marketing activities, websites have the potential to remove the disparity between what larger universities are able to accomplish and what smaller ones would like to achieve. But establishment of a website provides no guarantee that visitors, especially prospective students, will find what they seek within a reasonable time frame. Therein rests the dilemma for institutions - failure to locate desired information or difficulty negotiating the site might, and likely do, lead prospective students to exit. The focus of this research study was two-fold: to evaluate the extent to which university websites use relationship marketing techniques to communicate with prospective students and to evaluate the usability of these sites. This book is addressed to professionals in higher education responsible for student recruitment and marketing.

"Adding Ajax" is ideal for intermediate to advanced web developers who are worried and confused about Ajax, thinking that it will force them to start over with their craft. This refreshing guide will calm those fears by offering an entirely new approach to the topic. Rather than introduce Ajax as a completely new way of doing things, this book shows you how to integrate Ajax with existing sites, and does so by building to Ajax rather than building from an Ajax foundation. By reading this book, you will learn how Ajax allows you to create "rich" web applications, but more importantly, you'll see how the practices you already follow feed right into Ajax - and that, in most cases, you already work with the technologies involved. Adding bits and pieces often makes much more sense than tearing down and rebuilding, and you'll learn to integrate Ajax with your usual process. This book: provides an overview of the Ajax technologies, and the importance of developing a strategy for change to your site before sitting down to code; offers nuts and bolts coverage of the heart and soul of Ajax: how to work with the XMLHttpRequest object; introduces and demonstrates several of the more important Ajax libraries, including Prototype, script.aculo.us, rico, Mochikit, and so on; and gets into the interactive element that is Ajax, including how to work with events and event handlers that work across browsers. It also explores the concept of web page as space, and covers three popular approaches to managing web space; explains how to make data updates, including adding new data, deleting, and making updates, all from within a single page; explore the effects Ajax has on the Web -- breaking the back button, losing browser history, dynamic effects that disappear when the page is refreshed, and more; covers advanced CSS effects, including drag and drop 'scroll bars', pagination, and the use of SVG and the Canvas object; and explores mashups - Ajax's ability to bring in different web services, and combine the data in any number of ways, directly in our web pages. At the end of "Adding Ajax", there's reflection on whether starting over might be a fun idea, but by then you should be much more comfortable with it.

As Web-based interactive 3D graphics, popularly referred to as Virtual Reality (VR), continue to become more affordable, research and development groups in various fields have been adopting Web-based VR technology. Despite substantial adoption, how and how much the technology benefits target users and the providers who choose to adapt the technology is not well understood. Previous research has established that VR provides users with unique human-computer interaction. However, little is known about how users experience the Web-based VR technology and how user-system interaction contributes to system usability. This book investigates user perception of Webbased VR comparing to conventional 2D graphics and system usability affected by the user-system interaction process. The impact of Web-based VR on system usability was empirically examined from an integrated view of technology acceptance in information systems and human-computer interaction. In addition, the impact of user characteristics on user-system interaction while using a VR system was examined. This book provides new knowledge about usability, sense of presence and technology acceptance in VR and provides insights for future research, which should be important to anyone designing, developing and evaluating a VR system in general and to an electronic commerce or market research system in particular.

Our environment is more and more shaped by the influence of digital media which itself evolves at tremendous pace. A small example: 15 years ago, offthe- shelf computers were only able to cope with flat 2D graphics. Improvements in system design made it possible to process 3D scenes, leading to a powerful contribution to our everyday life. However, such scenes need to be created by experienced artists employing difficult and expensive tools. The increasing demand for realism makes things not easier. At the same time, the rapid improvement of commodity hardware enables the development of low cost systems for 3D photography. How can systems for volumetric scene reconstruction be efficiently designed? How may high quality be combined with real-time processing? And how is it possible to create a lightweight architecture using a single computer? After presenting an introductory overview and sketching a novel approach to scene reconstruction, the author Christian Nitschke gives a survey of related work in high-performance reconstruction by shape from silhouette and shape from photo-consistency. To convey a profound understanding to the reader he explains the fundamentals of scene and camera geometry, image formation, light and color as well as 3D reconstruction from multiple views. The novel approach is then introduced in two steps by mapping a basic algorithm to an advanced algorithm using graphics hardware acceleration. Performance and quality issues are analyzed and discussed in detail. The book aims at software and system engineers, scientists and researchers, technical directors as well as the interested public.
