Problems solved by technology

Therefore, it will occupy the keyboard space and cannot meet the requirements of the keyboard to minimize the space
Although some mobile communication devices have adopted touch or handwriting input solutions to replace traditional key input solutions, the price of touch screens is relatively expensive, and purchasing touch-screen mobile communication devices will increase the burden on users

Embodiment Construction

[0013] see figure 1 As shown, a small keyboard mobile device 100 includes: a body 1; a display device 2 is inlaid on one side of the body 1, the display device 2 can be a liquid crystal display, and the display device 2 can display a key array; A small keyboard input device 3 is inlaid on the same surface of the display device 2 , and the small keyboard input device 3 includes a direction key 33 , a first function key 34 , and a second function key 35 . The direction key 33 is circular and divided into four areas. The four areas of the direction key 33 are respectively provided with a first pressing part 331, a second pressing part 332, a third pressing part 333 and a fourth pressing part 334. Key 33 is used to move through the selected key array to enter the desired number / letter / symbol.

[0014] The first function key 34 surrounds part of the circumference of the direction key 33 . The first function key 34 is divided into two areas. A mode key 341 and an answer / call key 34...

Abstract

This invention relates to an input method for mobile device with small keyboard. Wherein, after pressing the mode key, direction key and enter key by turns, the host system reads opposite key array with letters arranged on the display device in matrix-form and every letter in one unit; the cursor is on a preset position and displays its position on display device; the most continues to detect whether there is press on the direction key; if yes, the host drives the cursor moving along the pressing direction with distance as the press time summation to match letter. This invention reduces key number to endow the key structure with least area.

Description

【Technical field】 [0001] The invention relates to an input method of a mobile device, in particular to an input method of a small keyboard mobile device. 【Background technique】 [0002] Many key input devices and character input methods have been developed in the field of mobile communication devices in order to easily represent desired characters while minimizing the area of ​​the key input devices as terminal sizes tend to shrink. These key input devices include known 3*4 key input schemes, such as the mobile phone shown in Taiwan Patent Publication No. 590577. [0003] The 3*4 key input scheme has been an obstacle to the miniaturization of mobile communication devices due to the minimum space requirement of the keypad. The minimum space requirement refers to the minimum space required for a user to precisely select a desired key on the keyboard and to separate the key from other adjacent keys on the keyboard when operating the keyboard. Currently commonly used mobile co...
