Mobile technology is changing the way people and corporations communicate with
each other. This technology is now used to talk, obtain information, play games,
and for a host of other reasons. The smallness of mobile devices presents a unique
set of problems that are not present in the desktop or laptop environment. In
mobile devices, buttons and styluses play a major role, but input processes are
slow. The small amount of information that can be displayed, and the slow speed
at which the user can get it, can also be quite annoying. Commands can be given
orally, but this technology is not yet mature. In short, the user interface is
the main concern in mobile devices. This book addresses this issue.
