Method and apparatus for inputting Chinese characters
First Claim
Patent Images
1. A Chinese character inputting apparatus, comprising:
- a keypad having a predetermined number of keys; and
a converter which converts depressed key information generated by said keypad into stroke data corresponding to character strokes, wherein the depressed key information for each provided Chinese stroke is entered by the pressing of any two or more keys of said keypad, and wherein;
the Chinese stroke “
”
is entered by pressing at least a first pair of horizontally oriented keys, the Chinese stroke “
”
is entered by pressing at least second pair of vertically oriented keys, the Chinese stroke “
”
is entered by pressing at least a third pair of keys oriented consecutively toward a lower-left direction, the Chinese stroke “
”
is entered by pressing at least a fourth pair of keys oriented consecutively toward a lower-right direction, the Chinese stroke “
”
is entered by pressing at least a fifth pair of keys oriented consecutively toward an upper-right direction, and an additional predetermined set of character strokes are entered by pressing two keys located respectively at peripherally opposing areas of said keypad.

Abstract
The inputting apparatus and method is disclosed which associates at least two keys consecutively pressed with a corresponding Chinese character stroke. When a user presses keys associated with the strokes constituting a Chinese character, the inputting method of the invention will generate various strokes based on the user input and then meaningful Chinese character. Since the Chinese character inputting method according to the invention is only concerned with the direction of consecutively pressing at least two keys, it is only necessary for the user to consider the direction of depression of the keys corresponding to the strokes when inputting strokes without considering which key is to be pressed, thereby greatly reducing the memory burden of the user.
