The user first presses the character key of the corresponding character in the handheld device 200 according to the stroke of the desired text, and the handheld device 200 matches at least the character of the character key 210 from the character database 280 according to the pressing order of the character key 210. A combination of required characters. When each word is entered, the user has to press more than one stroke character. When the user wants to input the word "bad", the stroke is a combination of "丨", "J", ",", and the strokes shown in Fig. 2A are arranged. The character key "2" and the character key are required to be sequentially input. 3" and the character key "4". The processor combines the stroke characters of the three-character key 210 to match the character database, and matches the desired character combination of "丨", "", ",". The handheld device 200 divides the dial area 230 into nine squares to display the desired character combination and at least one of the characters corresponding to the desired character combination loaded from the character database (step S320). The processor 270 reads at least one character corresponding to the desired combination of characters from the character database 280, and outputs the desired character combination to the display screen 220 along with the corresponding text. The display screen 220 divides the dial area 230 into nine squares when the desired character combination and its corresponding text are obtained. The middle grid of the nine squares is used to display the desired character combination, and the four surrounding cells adjacent to the middle grid are the selection area 233, and the selection area 233 is used to display the text corresponding to the desired character combination. 1377792 ·* As shown in Figure 4A, the required character combination matched by the processor 270 is "丨" "," corresponding text.

The text of U," to the word selection area 233, such as the second box: "small", the third grid: "less", the fourth grid: "dust" and the fifth grid: "tip". Next, the handheld device 200 analyzes whether any of the handheld devices 2 is pressed (step S331) or if at least one of the update buttons is pressed (step S330). ^ If the user judges that the selected word area 233 does not have the required text, the update key can be pressed to update the text loaded from the character database in the selected word area (step S332). The update method is as follows: First, as shown in FIG. 4B, pressing the forward update key 252 or the backward update key 251 'the processor 270 sequentially extracts four corresponding intermediate grids according to the order in which the characters are stored in the character database 28〇. The characters of the character combination, or the characters of the four character combinations corresponding to the intermediate cells are sequentially taken out to be output to the display screen 220. The display screen 220 displays the acquired text in the word selection area 233 in accordance with the code of the nine squares of the dial area 230. Secondly, as shown in FIG. 4C and FIG. 4D, the four corners of the nine squares are used as the candidate area 234. When the processor 270 obtains the text output from the character database 280 to the display screen 220, the next sequential text is simultaneously output to The screen 220 is displayed. The display screen 22 displays the acquired characters in the selected character area 233 in accordance with the code of the nine-square grid of the character area 23, and loads the text of the next-order sequence 9 into the candidate area 234. For example, Box 6: "Inferior", Section 7: "Province", Box 8: "Finch" and Box 9: "Thai". First, as shown in FIG. 4E and FIG. 4F, when the backward update key 251 is pressed, the processor 270 causes the display screen 22 to delete the text of the selected word area 233 and transfer the text of the candidate area 234 to the selected word. Field 233. Next, the processor 2 stores the text order according to the character database 28G, loads the text in the next order of the character combination corresponding to the intermediate grid (in this example, the order of the backwards) to the display 'screen 220' to display the screen 22 〇 The text of this sequence will be displayed in candidate area 234. 'Small is about, 4' replaces "small", "province" replaces "less", "bird" replaces soil", and Nai replaces "tip". The sixth box reloads the word "弋", the first L is loaded with *" child" in the eighth box, and the second box is loaded with the word "spirit". When the field presses the update button 252, the processor will The display screen 220 clears the text of the candidate area coffee, and the text of the word selection area 233 is transferred to the l area 234. Then, the processor 270 stores the character sequence of the character sequence of the manned pair according to the character database 280. The second-order (the order of the department to the other item) to the display screen 22 〇, showing the camp will move this time - the order The text is displayed in the word selection area 233. "If "inferior" replaces "t", "province" replaces "road", "bird" replaces "home", "thai" replaces stupidity" and the second box reloads "small" The word, the third box reloads the "less # μ 4th reloading "dust" word, the fifth box reloads the "tip" word. 1377792 By this, the player is based on step S330 and step S332 If the user finds that the desired text is in the previous selection, the forward update key 252 or the backward update key 251 can be pressed to return to the previously displayed text for the selection action. When the user does not press the update button, it is determined whether any of the direction keys are pressed (step S331). If any of the direction keys is not pressed, the representative display screen 220 does not display the text required by the user, and the handheld device returns. Step S330.
