MIDP Style Guide for the Java 2 Platform, Micro Edition

10.3 Touch Input

Some devices, such as PDAs, have touch input. It is not available on all devices, however. If a device has touch input, it should be incorporated into the canvas screens of applications so that these screens can behave like native applications and like the high-level screens of MIDP. (See "Touch Input" on page 231 for more information.)
