Chapter 20. Mobile and Wireless Systems > The Mobile User Experience

The Mobile User Experience

Market observers sometimes talk about the killer app for mobile devices of all kinds, and many think there isn't one yet. Actually, we think the killer app for small mobile devices is already clear: person-to-person communication. After all, that is obviously what drove the growth in mobile phones and pagers, and even some data services such as iMode in Japan. For larger mobile devices, such as the Palm, it is possible to provide limited interaction for focused applications, especially those that are useful to people moving around. Such applications include notifications of important news, maps and directions, and information about nearby locations. It is less clear if such devices will ever be commonly used simply to buy books or other items on the Web.

This suggests that there are two kinds of interesting applications for mobile devices: those of particular interest to customers on the move, and those that are useful adjuncts to other e-commerce applications whose main use is on the Web. Obviously, there is a large category of other mobile applications for specific uses, or internal uses within companies and other organizations, but they are outside the scope of this book.
