Webmaster's Guide to the Wireless Internet part 37. The Webmaster’s Guide to the Wireless Internet provides the Wireless Webmaster with all of the tools necessary to build the next generation Internet. Packed with the essential information they need to design, develop, and secure robust, e-commerce enabled wireless Web sites. This book is written for advanced Webmasters who are experienced with conventional Web site design and are now faced with the challenge of creating sites that fit on the display of a Web enabled phone or PDA | 332 Chapter 7 Deck of Cards Designing Small Viewpoint Content Summary In this chapter we have discussed the pyramidal navigational structure that is fairly prevalent on the WWW We have discussed the many mistakes that are commonly made by Webmasters making the transition to wireless and how these mistakes are largely the result of an attempt to represent the WWW on a smallviewpoint device. In order for Webmasters to provide effective compelling applications it is necessary for us to work within the constraints of the wireless involves accommodations of a technical nature such as the minimized use of images and extraneous markup as well as accommodations of a human nature such as taking mobility into consideration and minimizing the data a user must input to interact with an application. There are some unique features to WML that allow us to send multiple screens to the user at once and it is possible to use this feature to our user s advantage by limiting the number of server connections that must be initiated by the handheld device. It s possible to build a swift-feeling application by making use of the hub-and-spoke metaphor and parceling our site into one deck for navigation and several decks of content. In addition a linear task-based navigation scheme will result in a more efficient relay of information to the user. In this chapter we also examined the display differences among the different browsers and found that there are significant differences in how the most common WML browsers display content and UI elements. Designing an application and branching your code with these differences in mind will help to ensure the best user experience possible. It is of critical importance to test your applications on a wide variety of devices and although we re dealing with a great many devices and input mechanisms it is possible to apply some thought to the usability of our applications so as to create a more effective user experience. Last but certainly .
