Problems solved by technology

However, in order to apply traditional techniques, the rollers must have enough room to move laterally
Therefore, conventional techniques are not suitable for portable terminals because space saving is an important factor in the design of portable terminals

Abstract

A wheel input device and a method thereof enable a four-way key stroke, space saving, effective key arrangement, and suitability for existing operating systems or application programs by using a scroll wheel. A direction change button may be used to control the directional property of the scroll wheel. By rotating the scroll wheel in the up / down direction after clicking the direction change button, a cursor on a screen display unit moves in the right / left direction differently from its initial function. By clicking the direction change button once again, the function of the scroll wheel returns to its initial function. A specific function may be set for a long click of the direction change button. Alternatively, a click identification unit may be used, instead of the direction change button, to provide a four-way key stroke.

Description

Technical field [0001] The present invention generally relates to a wheel input device of a portable terminal and a method thereof, and more specifically, to a method of enabling four-way key stroke of a scroll wheel installed in the portable terminal. Background technique [0002] The latest developments in semiconductor circuit integration technology and information and communication technology have led to the widespread use of personal portable terminals such as mobile phones, personal digital assistants (PDAs), and the like. Input devices such as keyboards, touch screens, joysticks, scroll wheels, etc. are commonly used in portable terminals. Joysticks or scroll wheels are increasingly being used in portable terminals to enhance messaging. This trend reflects the need for fast and convenient user interfaces. [0003] The scroll wheel (also called a track wheel or scroll wheel key) is an input device that typically provides three functions such as up / down movement and confirma...
