摘要

A mobile radio terminal or palm computer is equipped with ergonomic and intuitive operating functionality by precise control of a pointer and cursor on a display. Popular personal computer-type operating processes are used to positioning and performing editorial processing. An ergonomic arrangement of control buttons on the front of the case or the sides, in line with the fingers, allows powerful applications to be operated with either the left or the right hand while the device is held securely in the same hand.
