Abstract

The invention discloses an input system and an input method for a portable terminal, and the portable terminal. The input system comprises a sphere, a rotating detection unit, a click detection unit and a control unit, wherein the sphere is partially embedded into the outer surface of the portable terminal, can rotate under the action of an external force and can click towards the direction of a main body; the rotating detection unit is positioned at the lateral part of the sphere, and used for outputting corresponding electric signals according to the rotating direction of the sphere; the click detection unit is positioned at the lower part of the sphere, and used for outputting the corresponding electric signals according to the click of the sphere; and the control unit is connected with the rotating detection unit and the click detection unit, and used for receiving the electric signals output by the rotating detection unit to control the movement of a cursor in a screen display unit of the portable terminal and receiving the electric signals output by the click detection unit to determine the content selected by the cursor. The input system of the invention has the advantages of simple and convenient operation, high response speed and low cost, and is not easy to damage.

Description

technical field [0001] The present invention relates to the technical field of electronic equipment, in particular to an input system and an input method in a portable terminal, and a portable terminal. Background technique [0002] The latest development of electronic technology and information communication technology makes personal portable terminals widely used, and more and more input devices and methods are used for cursor direction control of portable terminals, including four-way keystrokes, joysticks, scroll wheels, touch screens, etc. , a trend that reflects the need for fast, easy user interfaces. [0003] The four-way keystroke is an input device that can move the cursor up, down, left, and right in four directions by clicking different buttons. It is an interface commonly used in portable terminals at this stage, but its response speed is slow and it takes up a lot of space, which is not conducive to portable terminals. development, and pressing keys for a long...
