Abstract

The present invention relates to a method for continuously inputting characters through keys having a plurality of characters arranged on each of them, on a keyboard for inputting characters through a multi-tap method. The method according to the present invention of inputting relevant characters by successively pressing keys in a continuous manner uses the time between keys to divide one successive stroke at suitable positions and make the successive stroke two successive strokes. The character inputting method according to the present invention does not wait until a successive stroke acknowledging time elapses and does not use a successive stroke end key, but allows successive strokes to be continuously entered so as to allow characters to be quickly input. When the character inputting method according to the present invention is used, relevant successive stroke inputs can be made at any time for all characters on a keyboard that uses a multi-tap method, in order to provide consistency, speed, and simplicity to the character inputting method.

Description

Character input method

A device that inputs characters in a multi-tap method on the keyboard of small electronic products such as mobile phones and remote controls. In particular, a method for inputting characters by pressing the batting in a row.

If you assign an English alphabet to each key on a 12-key keyboard, you cannot assign every alphabet to a key. The same is true for phonemes in Korean. Therefore, a plurality of characters are assigned to one key. In addition, a method called 'multi-tap method' or 'in-sitta method' is used to select and input one letter among the assigned letters.

In this method, when a key is repeatedly pressed two or more times, the elapsed time between the key and the key press (hereinafter referred to as the 'kigan time') is calculated, and if the kigan time falls within a predetermined 'battery recognition time', the key is moved back and forth. Pressing it together counts as one 'hit'. The batting is not limited to pressing the second key. This is because it is possible to press the key smaller than the batting time. All the keys you have pressed will be counted as one batter. In one batter, the first key press is called '1 stroke', the second key press is '2 strokes', the third key press is '3 strokes', and the fourth key press is called '4 strokes'. Let's also call it 'the bell'. Then, the key time between 1 and 2 strokes is 12 birds, the key time between 2 and 3 strokes is 23 birds, and the key time between 3 and 4 strokes is 34 birds. do. Among the batters, the only key press is one stroke, 'Danta', up to 2 hits, 'This batter', up to 3 hits, 'three batters', and up to four hits will be called as 'four batters'. If you press the key less than the battered recognition time after pressing the first stroke, pressing the 2, 3, or 4 strokes repeatedly inputs the first single stroke, and the single stroke changes to this batter, and this batter is three batters. The change of three batters to four batters will be called 'development of battering'. If the key interval exceeds the battered recognition time when one key is repeatedly pressed, the development of the batter ends at that position, and the subsequent key press is the first bat of the new batter. Then, for the other stroke, the first letter assigned to the key, the second character for the batter, and the third character for the third batter are entered. Using this method, you can select and enter the required character even if several characters are assigned to one key.

Using the multi-tap method or the in-situ method (hereinafter, referred to as the 'multi-tap method'), even if a plurality of characters are assigned to one key, a required character can be selected and input. However, in the case where two or more characters in a key to which a plurality of characters are assigned are inputted in succession, two or more consecutive batters, three batters, three batters, etc. must be pressed in succession. When a user presses a key to press the batter after a batter in a key, the user must delay more than a predetermined battering time before pressing the batter of the previous batter and then the batter of the next batter. This will prevent the development of batters between two batters. Here, the two batters of the previous battered and one battered in the rear batter will be called 'two battered birds'. Since the conventional batter recognition time is considerably larger than the kigan time when the user presses the batter, the time to wait to exceed the batter recognition time is felt to be quite long, making the user feel uncomfortable. Therefore, a problem that is likely to occur in the case of inputting in this way is that if the next key is pressed while the delay time is still not enough to exceed the predetermined battering recognition time, the batter develops, but the battering is unintentional. To throw it away.

Taking this into account, the 'end of batter' feature appears. Even if the predetermined battering recognition time has not expired after pressing the key, if the battering end is input, the battering is completed as the key pressed before the end of the battering, and the new battering starts from the end of the battering, and the next key is pressed. To make a shot. Because of the difficulty in assigning a battered end to a separate key in situations where there is a lack of keys on the keyboard, it is common to assign it to a key that enters a space or a key that moves the cursor to the right. When you need to continuously press the batter in order to input two or more of the letters assigned to one key consecutively, pressing the battering end key on the two battering birds allows you to press the keys continuously without delaying the battering recognition time.

Several new problems are introduced here. In simple terms, you need to assign a key to end the batter and press the key once more, but if you look closely, you can use the batter end key together with the space key or the cursor movement key to create a more complex problem. . For example, a key assigned to O and P will be called 'O key' for a while, and someone who wants to press O key + battered end key + O key to enter 'OO' will drag it for some time. When the battered timeout expires, the O key + battered timeout + battered end key + O key is pressed, and the battered end key pressed after the battered time expired is recognized as a space key. 'O O' is entered instead. This may be caused by a user's fault, but people are experiencing this much. If the battering end key is assigned to a separate key, the batter may not generate a typo even if the battering time expires in the middle.

These problems were regarded as an inevitable problem because the multi-tap method does not have to use the battered end to not wait until the end of the battered recognition time, and there is no separate key for the battered end.

The battering needs to be terminated because the only criteria for comparing the kigan time is the batting time and no other comparison criteria. That is, when the predetermined battering recognition time has not yet expired, the battering power generation is cut off and new battering input is required. Therefore, in order not to use the battering termination that plays such a role, in addition to the battering recognition time, another criterion for terminating the battering by comparing the key time is needed.

One other criterion is the user's key time values. If the kigan time is within a predetermined battered recognition time, the key pressed back and forth is a battered battering, 12 birds, 23 birds, 34 birds, etc. of battered battered time will be called 'battery bird'.

When you press two batters in a row in a row, the first batter hits the first batter and the second batter stops before pressing the first batter. The battered battered battered battered battered battered batter and battered battered batters. That is, if the Kigan time of two battering birds is smaller than the predetermined battering recognition time, the kigan time becomes a battering bird, and the two batters become one battering together. The battered bird that stops at two battering birds and delays a shorter time than the predetermined battering recognition time is called 'floating bird' because it is time. Compare your battered birds with one another to distinguish between them. Thus, when one battering bird is larger than a predetermined multiple by the other battering bird, it is classified as floating bird. In addition, the average of the user's hovering birds will be referred to as 'blow separation time'. Therefore, the batter separation time is not constant and has a feature that varies depending on the user's habit. The following is a method for continuously pressing the batter without inputting the end of the batter by using the user's key time and the battered separation time together with the battered recognition time. It is a case of continued development. In the first three letters assigned keys,

(1) Pressing a key while waiting for another stroke generates a single stroke. Enter 1 character corresponding to other type. 2 Set to standby.

(2) Press the key while waiting for two hits, this batter occurs. Cancel the character entered at other stage. If 12 birds are less than the battered separation time, enter one character for this batter and set it to 3 strokes. 12 If the bird is greater than the battering separation time, terminate the batter between 1 and 2 hits, divide the batter into 2 batters, enter two letters corresponding to the batter, and set the 2 batters to standby.

(3) If you press the key in three strokes, three batters will occur. Cancel the character entered in this batter. If 12 birds and 23 birds differ by less than a predetermined multiple, enter one character corresponding to three batters and set it to 4 strokes. If 12 birds are larger than 23 birds by a predetermined multiple, the batter is terminated between 1 and 2 hits, divided into 2 batters, and the batter and 2 letters corresponding to the batters are input and set to 3 strokes. When 23 birds are larger than 12 birds by a predetermined multiple, the batter is terminated between 2 and 3 hits, divided into 2 batters, and 2 characters corresponding to the batters and single hits are entered, and the second hit is set to waiting. When the two key intervals differ by more than a predetermined multiple, the average value of the large key interval and the batter separation time is determined to reset the batter separation time.

(4) If you press key while waiting for 4 strokes, 4 consecutive hits will be generated. Cancel the character entered in the three hits. Compare 12 birds, 23 birds, and 34 birds with each other, and if 12 birds are the largest, terminate the batter between 1 and 2 hits, divide them into 2 batters, and enter 2 letters that correspond to the single and triple hits. Put it in the air. 23 If the bird is the largest, the batter is terminated between 2 and 3 strokes, divided into 2 batters, and the batter and 2 characters corresponding to the batters are entered. 34 If the bird is the largest, finish the batter between three and four strokes, divide it into two batteries, enter two characters corresponding to three batters and single batters, and set them as two batters.

Here is a key with two letters assigned to it:

(3) If you press the key in three strokes, three batters will occur. Cancel the character entered in this batter. If 12 birds are larger than 23 birds, the batter is to be terminated between 1 and 2 strokes, divided into 2 batters, and the batter and 2 letters corresponding to the batters are put in the air. If 23 birds are larger than 12 birds, the batter is terminated between 2 and 3 strokes, divided into 2 batters, and the two characters corresponding to the batter and the batter are input.

In the character input process using the above means, the user's key-to-key time and a predetermined battering recognition time are compared. However, the user's key-to-key time and battering separation time are used to determine the position of the batter's end and divide one batter into two batteries. Method, the battering end key is not used. Because the user's battered birds and battered separation time is very small compared to battered recognition time, analyzing key presses in this way is very useful when you need to press keys quickly. This is the method used when you press the batter consecutively to enter the characters on the key assigned to multiple characters in succession, but this makes it possible to speed up the battering process without delaying the battered recognition time or pressing the battering end key. Provides consistency for the input to proceed.

8 and 9 are flowcharts illustrating a process of determining a character to be input when the EFG repeatedly presses an assigned key.

10 is a flowchart illustrating a process of determining a character to be input when an AB repeatedly presses an assigned key.

1 to 6 show a keyboard for inputting characters according to the present invention. Keyboards require double punctuation and numbers, and keys, as well as functions to control input such as spaces, backspaces, and deliits, are also required. In French, German, Spanish, Italian, etc., various symbols may be attached above or below the alphabet, or special characters may be used, and a keyboard for inputting these characters is shown in FIG. 5.

Here, each of the 12 keys on the keyboard is named. 12 to 12 are arranged in the same shape. 7 shows the buttons of a conventional digital telephone. The 12 keys in each diagram are given the same name for the keys in the same position around the keys in FIG. 7. In FIG. 7, the number 1 is written as 'key 1' and the number 2 is written as 'key 2'. And continue this way and call the key with the number 9 called key 9. The key with * is called 'key *', the key with 0 is called 'key 0', and the key with # is called 'key #'.

From the standpoint of handling input from the keyboard, the user presses a key that has a letter assigned to it, and an event has occurred, and each occurrence of the event requires appropriate action. It is to type the character assigned to the pressed key. If a letter is assigned to a key, all necessary actions are completed by entering that letter each time an event occurs. However, when two or more characters are assigned to a key and the multi-tap method is used, a more complicated procedure is required. In other words, whenever an event occurs, the relationship with the previous case must be investigated. If the investigation occurred in a key different from the previous case, the other event occurred and the end of inputting the first letter assigned to the key in which the event occurred. However, if the event occurred in the same key, the time of occurrence of the event should be investigated to find the key time and compared with the batting time. If the Kigan period is longer than the predetermined battered recognition time, the other type of event has occurred and the action is ended by entering the first letter assigned to the key in which the event occurred. However, if the kigan period between the two events is less than the predetermined battering recognition time, the batter has occurred, the action should be taken according to the battering. In the event of a battered batter, the characters entered in the previous case must be canceled first, and then measures taken in accordance with the development of battered batters. In other words, if the previous event is a single batter, this battering, or three battering, it is determined that the batter is a battered batter, this battered battered battered batter, and a battered battered battered battered battered by three batteries. Enter a letter or, if there is no letter assigned to the key, such as a multi-hit case, enter the letter as previously determined.

In the conventional battering processing method as described above, whenever an event of pressing a key occurs, the relationship with the previous event is examined to determine whether the batter is battered. The battered recognition time applies to all phases of battered development. Therefore, in order to stop the development of such battering, it is necessary to delay the time exceeding a predetermined battering recognition time or use the battering end key.

However, since the battered recognition time is commonly applied to all users, it was necessary to set a value that does not cause any problem for inputting a character even if a person has a slow hand movement. Most people are more difficult to hit three batters than this batter. Therefore, a large enough value was used as the battering time so that even a person with slow hand movement could input three batters without difficulty. A simple measurement showed that when people were hitting one key, the key time was about 130-220 ms (milliseconds). However, since the batter recognition time is generally about 2-4 s (second) in the conventional keyboard using the multi-tap method, there is a difference of about ten times compared to the keying time.

In the keyboard using the multi-tap method, the characters in a key assigned with a plurality of characters are continuously inputted. If two batters do not use the battering end and do not delay the predetermined battering recognition time, the batter is continuously pressed. The whole will be a battered one. There must be some distinction between the batters in order to separate each batter one by one. That is, what is necessary is just to have a means which divides a batter and a batter. Here, if a floating bird that stops at two battering birds and delays a shorter time than a predetermined battering recognition time can be made larger than another battering bird, this may be a means of dividing battering and battering. If the distinction between battered birds and floated birds is clear, the battered battering should be divided and the battered battered development at the position of two battered birds.

However, as a result of a simple measurement, when people pressed the battered key on one key and stopped, it delayed briefly and continued to press the key immediately afterwards, and the delayed key length was about 250-450 ms. It took some time to stop and start again, so it wasn't easy to reduce this time smaller.

In the present invention, a batting bird and a floating bird for distinguishing battered battered and battered battered when pressing battered consecutively are used for the intermittent time when the batter is pressed at one key and the delayed time between pressing the batter. There is a sufficient difference between the two because there is a nearly double difference between the two measured values. In order to ensure stable division in operation, set the predetermined multiples as small as 1.5, compare the battered birds with each other, and classify the new ones that differ by more than the predetermined multiples, and set the battered separation time as the average of the classified birds. Repeat.

The user simply stops pressing the keys on two battering birds in order to press the batters consecutively on one key. This is the same as pressing a key between battering and battering when typing characters in a multi-tap mode. This is not a new or special requirement for floating birds. For example, if you need to press these batters and hitters in succession, no one would think that you would press the keys three times in succession, pre-calculating the number of keys to press and keeping the key-to-key time the same. Therefore, the user who inputs the text by the multi-tap method stops pressing the key momentarily between the batter and the single stroke. This is the same as having already distinguished and entered battered birds and floating birds, so that the distinction between battered birds and floated birds is automatically made by pressing a key according to the conventional habit.

8 and 9 are business flowcharts showing the development of battering when battering occurs by repeatedly pressing the key 3 to which the letter EFG in FIG. 1 is assigned. Rather than having a single battered recognition time to determine all changes in batteries, more detailed criteria are applied at each stage of battering, such as comparing keygan times with each other or batter separation times obtained from a user's floating bird. In FIG. 8, when the key 3 is pressed in the first or one standby state, the key-to-key time is calculated. Before the key 3 is pressed, the elapsed time from the last key press to the time the key 3 is pressed is calculated. In the work flow chart, the key press time is greater than the battered recognition time, or the state value is pressed, and the key is pressed by one stroke, but E is displayed by the other input and the second stroke is in standby status.

In key 2 standby mode, key 3 standby mode or key 4 standby mode, if key 3 times greater than predetermined battering recognition time, press key 3, follow the work flow chart and press key becomes 1 stroke of new batter. Is displayed and the other two standby states.

If you press the key 3 less than the predetermined battering recognition time in the 2 other waiting state, the key is 2 hits.If you follow the 2 other waiting state in the work flow chart and 12 birds are larger than the battering separation time, between 1 and 2 strokes, End the batter at, and divide the 1 and 2 strokes into a single and a single stroke, change the display to EE, change the current 2 strokes to 1 stroke, and leave the 2 strokes in the standby state. If 12 birds are shorter than the battered separation time, the batter will advance and combine the 1st and 2nd batters, this batter will be changed to F, and the 3rd standby will be in standby.

If you press the key 3 less than the predetermined battered recognition time in the 3 other standby state, the key is 3 hits. In the work flow chart, follow the 3 other standby state and compare 12 birds and 23 birds. If more than a predetermined multiple, the batter ends the batter between the 1st and the 2nd batter, and the 1st hit is a single shot, the 2nd and 3rd shots are divided into 2 batters, divided into two, the display changed to EF, and the current 2nd hit is changed to 3 Change the stroke to 2 and leave it in the 3 stroke standby state. If 23 birds are larger than 12 birds by more than a certain number of times, the batter is terminated between 2 and 3 strokes, and the 1 and 2 strokes are combined to form this batter, and the 3 strokes are divided into two and the display is changed to FE. Changes to 1 stroke and enters 2 stroke standby status. If 12 birds and 23 birds do not differ by more than a certain number of times, one stroke, two strokes, and three strokes add up to three strikes, change the display to G, and enter the fourth stroke. If 12 birds and 23 birds differ by more than a certain number of times, the larger kigan time of the two birds is the floating bird, and this floating bird is added to the current battering separation time and averaged to set a new battering separation time. Floating birds for resetting battering time are available elsewhere, but here is the best.

If the key interval time is less than the predetermined battering recognition time in 4 other standby state, press key 3, and the key press is 4 strokes. In the work flow chart, follow the 4 other standby state and compare 12 birds, 23 birds, 34 birds with each other. If is the largest, the batter ends the batting between 1 and 2 strokes, and the 1 batter is the single batter, the 2 batters, the 3 batters, and the 4 batters are divided into 2 batters, the display is changed to EG, and the current 2 bats are 1 batter, 3 Change the bat to 2, then the 4 to 3, and put it in the 4th standby. 23 If the newest bird is the largest, the batter must finish the batting between the two and three strokes, adding one and two batters to this batter, and combining the three and four batters into two batteries. Changes 1 hit, 4 hits to 2 hits, and 3 hits. 34 If the bird is the largest, the batter must finish the batting between the three and four strokes, adding one, two, and three shots to three batteries, dividing the four shots into two, changing the display to GE, and replacing the current four shots with one stroke. Change and wait for the second stroke.

Even if three characters are assigned to a key, the reason why the 4th waiting state and 4th processing are needed can be easily seen by deleting the ones below the 4th waiting state in the work flow. If no other processing is performed, it becomes impossible to input EG, FF, and GE without using the battering end key and not waiting for the expiration of a predetermined battering approval time.

In the following case, two characters are assigned to one key. 1 to 7, in Korean keyboard, two letters are often assigned to one key. For example, ㅜㅋ, ㅗ ㅌ, ㅓㅋ, ㅡ ㅎ. However, in English keyboards, no two characters are assigned to one key. Although three letters are assigned to the key 1 of FIG. 1, it is assumed here that only AB is assigned to the key 1 for a while. 10 is a flowchart illustrating the development of battering when battering occurs by repeatedly pressing key 1 assigned to AB. In addition to battering recognition time, more detailed criteria are applied to each stage of battering, such as Kigan time and battering separation time. If you press key 1 for the first time or one stroke, the key time is calculated. Before the key 1 is pressed, the elapsed time from the last key press to the time the key 1 is pressed is calculated. In the work flow chart, if the key time is greater than the battered recognition time or follow the state value, the key is pressed by one stroke, but A is displayed by the other input and the second stroke is in standby status.

If key1 time is larger than predetermined battering recognition time in 2 other standby state or 3 other standby state, press key 1 and follow the work flow chart.Pressing key becomes 1 stroke of new batter, and displays A according to other input and displays 2 strokes. The standby state.

If key1 time is less than predetermined battering recognition time in 2 stroke state, press key 1, and the key is 2 strokes. If 2 birds are bigger than batter separation time in the work flow chart, between 12 strokes The batter ends the batter at the end of the battered battered battered battered battered battered battered battered battered battered battered. If 12 birds are smaller than the battered separation time, the batters will advance and combine the 1st and 2nd batters, this batter will be changed to B, and 3 batters will be in the standby state.

When key1 time is smaller than predetermined battering recognition time in 3 other standby state, press key 1, and key is 3 strokes. In the work flow chart, go to 3 other standby state and compare 12 birds and 23 birds. If it is big, the batter ends the batter between the 1st and the 2nd batter, and the 1st hit is a single shot, the 2nd and 3rd shots are combined, and the batter is divided into two. Change it and leave it in the third stroke. If 23 birds are bigger than 12 birds, the batter must finish battering between 2 and 3 strokes.

Combine

1 and 2 hits to make this batter, 3 hits are divided into two, change the display to BA, and change the current 3 hits to 1 stroke. And two other standby states.

Even if two characters are assigned to a key, the reason why the third-wait state and the third-way process are needed can be easily seen by deleting the ones below the third-wait state in the work flow. If the third batting process is not performed, it becomes impossible to input AB and BA without using the battering end key and not waiting for the expiration of the predetermined battering recognition time.

Initially, the battered recognition time can be started with 3 second and the battered separation time of 400 milliseconds. The battered separation time is the average of the floated birds. The average value is obtained in addition to the time to reset the battered separation time, the following equation can be used, and the battered separation time adjustment shown in FIG.

Multi hit time = (double hit time × W + float) / (W + 1)

Here, W is a weighted value, so it is not possible to store all existing floating birds and average them, so choose a proper positive number and apply the weight to the current battered separation time.

Where a multi-tap type keyboard is required, it can be used wherever the user wants to continuously input the batter without waiting for the expiration of the battered recognition time and without the batter end key. Mobile phones, TV remotes, car GPS, tablets, MP3 players and more.
