Description

a method of inputting characters in a character set by using a button,

Keyboard and information processing device

The present invention relates to the field of information processing, and in particular, to a method for inputting characters in a character set using a key, a keyboard, and an information processing apparatus. Background technique

In the field of conventional information processing, for the technique of inputting characters by using a button, there is a technique in which a button corresponds to an input character. For example, in a personal computer, there are buttons representing the English letters A-Z and buttons representing the numbers 0-9. When any one of the buttons is activated, the English letter or number corresponding to the button appears on the screen. When you need to input Chinese characters (for example, you can use the purple Chinese input method, etc.). When the pinyin corresponding to the Chinese character is input, a display bar appears on the screen, and the display bar displays the Chinese character having the pinyin, and the user selects a correct Chinese character therefrom. When it is necessary to input Japanese, the user uses the alphabetic key A-Z in the state where the language selection is set to Japanese, and enters the Roman phonetic symbol of hiragana, and the corresponding hiragana appears on the screen. Another example is the calculator. On the calculator, there are buttons representing the numbers 0-9 and buttons representing the symbols "+", "-", "x", "÷", "=". The user inputs the expression using the keys representing the numbers 0-9 and the keys representing the symbols "+", "-", "x", "÷". When the user enters "=", the final result of the operation appears on the LCD display. A feature of these traditional methods is that a button corresponds to a character. The characters in the character set that the user wants to input uniquely correspond to one button, so many buttons are required. When the number of keys is less than the number of characters in the character set, it will not work. Therefore, the number of technical buttons transmitted using the keys to input characters is large, and the keyboard volume cannot be reduced.

With the development of information processing technology, the volume of the keyboard needs to be smaller and smaller. The number is getting smaller and smaller. Traditional keyboards and methods of inputting characters using keys have been unable to adapt. Summary of the invention

It is an object of the present invention to accommodate the needs of modern information processing techniques, to reduce the number of keys required in character input, and to reduce keyboard volume.

One solution of the present invention is to multiplex some of the characters in the character set with a single button, and use a limited number of keys to input characters in a more concentrated set of keys than the number of keys.

The present invention provides a method for inputting characters in a character set by using a button. The number of characters in the character set is greater than the number of the buttons. The method includes: allocating all the characters in the character set to the button. At least one of the keys is assigned a plurality of characters in the set of characters; distinguishing the characters assigned to the at least one of the keys; wherein the combination of the selected characters in the selected set of characters produces the desired complete character.

The present invention provides a keyboard, including a button for inputting a character in a character set, the number of characters in the character set is greater than the number of the buttons, wherein all the characters in the character set are assigned to the button, At least one of the keys is assigned a plurality of characters in the character set; the characters represented by the at least one key are distinguishable.

The present invention provides an information processing apparatus, including: a keyboard, including a button for inputting characters in a character set, the number of characters in the character set being greater than the number of the keys, wherein all characters in the character set are all assigned to The button, at least one of the buttons is assigned a plurality of characters in a character set; the characters represented by the at least one button are distinguishable; and the display screen displays a result of inputting characters through the keyboard.

Since the present invention multiplexes certain characters in a character set by one button, the number of keys required for character input is saved, and the keyboard volume is reduced. DRAWINGS

Figure 1 is a flow chart of the method of the present invention. The present invention provides a method for inputting characters in a character set by using a button. The number of characters in the character set is greater than the number of the buttons. The method includes: allocating all the characters in the character set to the button S1. The at least one of the keys is assigned a plurality of characters in the character set; and the at least one button assigned with the plurality of characters in the character set distinguishes the character S2 represented by the at least one button.

For example, the character set is a number 0-9, "+,,""-","x","÷","=", has 15 characters, only two buttons, respectively, numeric keys and arithmetic symbols Buttons, where the number buttons are assigned numbers 0-9 characters, and the operator buttons are assigned "+", "-", "x,,""÷","="5 buttons. Thus, for a numeric button, it is necessary to distinguish which of the 0-9 characters is represented; for an operator button, it is necessary to distinguish between "+", "-", "x", "÷", "= "Which character of the 5 characters. The following is a discussion of how a button assigned to a plurality of characters in a character set distinguishes the character it represents. The distinction is mainly in two ways:

(1) distinguishing between characters represented by the at least one button by means of activation of the at least one button.

1) distinguishing between the characters represented by the at least one button by means of a time interval between two activations of the at least one button. For example, if the time interval between two activations of the at least one button is less than the preset duration T, then the character represented by the at least one button is switched once. For example, T = 0.2 seconds can be specified in advance. If the at least one button is activated and is not activated again within the preset duration ,, or the other button is activated after the at least one button is activated, the character input is successful.

Take the above example as an example. For example, you would enter the equation "9x5 = ". The digital keys representing the numbers 0-9 are successively activated nine times in succession, wherein the time interval between each two consecutive activations is less than Τ. Since the digital button initially represents 0, after one activation, the button is switched to represent 1, and after two activations, the button is switched to represent 2, and after 9 activations, the button is switched to represent 9. Then the operator symbols representing "+", "-", "x", "÷", "=" are activated, and the "9" input is considered successful. The symbol keys are then activated twice in succession, with a time interval between each two consecutive activations being less than T. The initial operation symbol button represents "+", and after switching once, it switches to "-", and when it is activated twice, it switches to "x". Then activate the number button and the "9x" input is successful. The digital button is then activated 5 times in succession, and the time interval between each successive activation is less than! ¹ . Then, activate the arithmetic symbol button and the "9x5" input is successful. Then, the arithmetic symbol button is continuously activated 4 times. After the predetermined time T has elapsed, "9x5=" is entered successfully and the result is 45 on the display.

2) There is also a mode button in addition to the at least one button, and the activation mode button causes the at least one button to represent a specific character.

2 is a mode switching mode of a five-dimensional calculator according to Embodiment 1 of the present invention; Example of a button example. In order not to obscure the inventive point of the invention, the display portion of the calculator is not shown, only the button portion is shown. There are 7 keys in the button part, among which there are 5 input buttons and 2 function buttons. Among the 5 input buttons, the upper button is used to input the number 0, 1/ operation symbol "+"; the right button is used to input the number 2, 3/ operation symbol "one"; the lower button is used to input the number 4, 5/ operation symbol "X"; The left button is used to enter the number 6, 7 / operator " ÷ "; the middle button is used to enter the number 8, 9, decimal point (·) / operator " = ". The two function buttons are the mode button and the delete button.

After the mode button is activated, enter the arithmetic symbol input mode and input the operation symbol. At this time, the above five input buttons represent "+", "-", "x", "÷", "=". When the active mode button is activated and an input button is activated, an arithmetic symbol is entered, which is automatically converted to digital input mode. In the digital input mode, when the interval between two activations of a button is within T, the content of the input is switched, such as: the up button activates the first input 0, if the second activation and the first activation If the time interval is less than T, the input changes to 1. If the time interval between the third activation and the second activation is less than T, since the button can only input the number 0 or 1, the input is changed back to 0, and so on. When the key of the input number is no longer activated within a period of time T, the digital input is considered successful or another key is activated after the number is entered (except for the delete button). The digital input is considered successful. Short activate delete button to delete one character entered, long activate delete button to delete all characters. The short activation delete button means that the duration of the activation of the delete button is less than or equal to the preset duration M. The long activation delete button means that the duration of the activation of the delete button is greater than the preset duration M.

Also take the input equation "9x5 = " as an example. First, activate the middle button (in this case, the input 8), and then activate the middle button again (in this case, the input 9) within the preset time length T. Then, activate the mode button, then activate the lower button (this represents the input operation symbol " _x ,,"). At this time, it automatically converts to the digital input mode. Then, activate the lower button (in this case, the input 4), and then in the pre- In the set time length T, the next button is activated again (in this case, the input is 5). Then, the mode button is activated and activated. Button (this means the input operator symbol "="). Display the result of the operation on the display

45.

3) If the activation duration of the at least one button is greater than a preset duration M (ie, long activation), then the at least one button is caused to represent a particular character.

Fig. 3 is a view showing an example of a button of a long-and-short activation mode of a five-dimensional calculator according to Embodiment 1 of the present invention. The display portion of the calculator is not shown, only the button portion is shown. There are 7 buttons in the button section, including 5 input buttons and 2 function buttons. Among the 5 input buttons, the upper button is used to input the number 0, 1/operation symbol "+"; the right button is used to input the number 2, 3/ operation symbol "one"; the lower button is used to input the number 4, 5/ operation symbol "X" ; The left button is used to enter the number 6, 7 / operator " ÷ "; the middle button is used to enter the number 8, 9 / decimal point (·). The two function buttons are the confirmation button and the delete button.

For the above 5 input buttons, long activation (ie the activation duration of the button is greater than the preset duration M) Enter the arithmetic symbol and the decimal point, short activation (ie the activation duration of the button is less than or equal to the preset duration M) Enter the number. Activate the confirmation button to get the final calculation result. When the interval between two short activations of an input button is within T, the content of the input is switched, such as: the upper button is short to activate the first input 0, if the second short activation is activated with the first short activation If the time interval is less than T, the input changes to 1. If the time interval between the third short activation and the second short activation is less than T, since the button can only input the number 0 or 1, the input is changed back to 0, and so on. When the key of the input number is no longer activated within a period of time T, the digital input is considered successful, or the key of the input number is activated after the short activation, and the digital input is considered successful, or the other key is activated after the number is entered (delete Except for the button) It is also considered that the digital input is successful. Short activate delete button to delete one character entered, long activate delete button to delete all characters.

Also take the input equation "9x5 = " as an example. First, the short-acting button (in this case, the input 8), then short-activate the middle button within the preset duration T (at this time) Representative input 9). Then, activate the next button (this time represents the input operation symbol "X"). After that, activate the lower button (in this case, the input 4), and then activate the lower button for a preset period of time T (in this case, the input 5). Then activate the confirmation button. The result 45 is displayed on the display.

(2) Distinguish the character represented by the at least one button by reselecting with a button.

1) responsive to the at least one button assigned with a plurality of characters in the character set being activated, displaying an association between the plurality of characters and the button by using a display screen, determining the at least one by using reselection of the button The character represented by the button.

In order not to obscure the inventive point of the present invention, the display portion of the five-dimensional Japanese input device is not shown, and only the button portion is shown. There are 5 input buttons and 2 function buttons. Among the 5 input buttons, the upper button is used to input a force, ka $ sa ft ta na ά ha ma ya ra wa/number 1; the right button is used to input i $ ki L si 3⁄4 ci ni X> hi * mi i 9 Ri i/number 2 ; the down button is used to enter 3 u < ku su cu i3⁄4 mi > hu mu *ø yu 3⁄4 ru u/ number 3 ; the left button is used to enter tei†ke 甘 se T te 3⁄4ι ne he 3⁄4 me X e L re X. e/number 4 ; The middle button is used to enter ^ o ko so t to 0) no (5 ho 3⁄4 mo ^ yo 3⁄4 ro 3⁄4 o/number 5. The two function buttons are the confirmation button and delete respectively. Button.

When you want to enter a Japanese hiragana, first select the vowel button corresponding to the hiragana. Five options on the display will correspond to the upper, lower, left, and middle buttons (or 1, 2). , 3, 4, 5). Then select the button corresponding to the hiragana (or select the number corresponding to the hiragana). Since each of the above buttons corresponds to 10 hiragana, the correspondence formed by the five selections is insufficient. The upper and lower buttons need to be the page up button and the page down button respectively. Short activate delete button to delete input One character, long activate delete button to delete all characters. The meanings of short activation and long activation are the same as in the first embodiment. Selecting the confirmation button will cause some commonly used characters on the display to include dialing "" and "sound". For the method of selecting these characters, refer to the vowel + navigation mode discussed below, so I won't go into details.

Take the input as an example. Since the corresponding vowel is 3⁄4>, select the button. At this point, the following association appears on the display:

Up button / number 1 -

Right button / number 2 - ,

Down button / number 3 - $

Left button / number 4 - †Z
