Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus and a method for controlling key input information, and more particularly, to an apparatus and a method for controlling key repeat of an information processing apparatus having a keyboard such as a computer and other electronic devices.

[0002]

2. Description of the Related Art Some conventional key input information control methods have an auto-repeat function, which aims at improving the efficiency of key input.

In Japanese Patent Application Laid-Open No. Hei 5-134792, as a "key input processing method", as a countermeasure against an error when the end of the key press is not detected in the key repeat, all keys on the keyboard are not pressed. A technique has been disclosed in which when a state is detected, a state indicating the state is transmitted to the apparatus main body.

[0004]

A first problem is that in the conventional auto-repeat function of key input, the repeat is started by pressing the key for a certain period of time or more, so that the repeat start due to an unintended input is likely to occur. That is.

[0005] The reason is that the condition setting for starting the repeat is a condition that is likely to occur accidentally.

[0006] The second problem is that if there is an excessive repeat, it may cause a malfunction of higher-level software, which may cause a failure such as data destruction.

[0007] The reason is that the repeat is continued as long as the input continues regardless of the intention.

The "key input processing method" disclosed in Japanese Patent Application Laid-Open No. 5-134792 has a problem that a special device is required on the keyboard side.

[Object of the Invention] An object of the present invention is to prevent key repeat due to erroneous input. Another object of the present invention is to prevent data destruction due to excessive input.

[0010]

According to the key input information control method of the present invention, comparison control means for comparing input information with setting conditions, output control means for outputting input data in accordance with conditions, and comparison setting conditions are provided. It has a condition storage unit for storing, and a condition setting means for writing a condition in the condition storage unit.

According to the present invention, as a means for solving the above-mentioned problems, in a key input control device, means for setting a start condition and an automatic stop condition of key repeat, and information of a storage unit set by the means are provided. Means for controlling the key repeat by comparing the input key input data with the input key input data.

A key input control method for setting a key repeat start condition and an automatic stop condition;
Controlling the key repeat by comparing the information in the storage unit set by the means with the input key input data, in order to solve the above-mentioned problem. Means.

[0013] In the key input control method, the key repeat start condition is that the same key is input a plurality of times within a predetermined time.

Further, the key input control method according to the present invention is characterized in that the automatic key repeat stop condition is a designated number of repeats.

[Action] The conventional auto-repeat of the key input to the computer has a function of automatically repeating the key if the key is kept pressed for a predetermined time or more.

For this reason, there is a possibility that an unintended input (for example, when an object is placed on the keyboard) may be repeated, and a repair work in the case of an erroneous input is large. It will take effort.

When the repeat is continued for a long time,
It is very dangerous because it can destroy data.

Therefore, according to the present invention, "input control means" for changing a condition for controlling key input, "output control means" for outputting a key signal input in accordance with the condition,
It has a “condition storage unit” for storing conditions and a “comparison control unit” for comparing inputs with the condition storage unit.

The start of key repeat /
Termination conditions can be set or changed to protect data against unintended input.

In the control method according to the present invention, for example, it is assumed that the key repeat start condition is that the same key is pressed twice or more within a predetermined time.

When this condition is met, the repeat is executed as long as the second key press is continued. If the condition is not met, only one character is output without repeating even if the key is kept pressed.

As a result, the probability of starting a repeat for an unintended input can be reduced.

Further, an upper limit is set for the number of repetitions, the number of repetitions is monitored during the execution of the repetition, and the repetition is automatically stopped when the number of repetitions exceeds a certain number.

Thus, data can be prevented from being destroyed due to excessive repetition, and data can be protected from unintended key input.

[0025]

Embodiments of the present invention will be described below in detail with reference to the drawings.

[Explanation of Configuration] FIG. 1 is a block diagram showing the configuration of the first embodiment of the present invention.
1, output control means 22, condition setting means 3, condition storage unit 4
It is composed of

The control unit 2 represents the entire control unit comprising the comparison control means 21 and the output control means 22.

The input data given from the keyboard 1 is supplied to the comparison control means 21.

The comparison control means 21 compares the input data with the set repeat start condition 41. When the repeat output is performed, the condition is compared with the automatic repeat end condition 42 for each repeat.

The output control means 22 is a part for outputting data to a higher-order program which is the next step, and outputs one character or repeats according to the comparison result of the comparison control means 21.

The condition setting means 3 is a part for setting a repeat start / automatic end condition in the condition storage unit 4.

The condition storage unit 4 includes a repeat start condition 41 and a repeat automatic end condition 42 as shown in FIG. 2, and stores the condition set by the condition setting means 3. The condition setting means 3 is managed by a host program, and can be set at an arbitrary timing according to an instruction from an operator.

[Description of Operation] Next, the operation of the first embodiment of the present invention will be described in detail with reference to FIGS.

The comparison control means 21 checks whether there has been a key input from a keyboard input (step 2 in FIG. 3).
10).

When there is a key input, it is first confirmed whether or not the condition is met for the repeat start (step 220).
If they do not match, a key code for one character is output (steps 220 → 230). If they match, repeat output is started (steps 220 → 240). Thus, even if the key is continuously pressed, the repeat can not be started until the repeat start condition is met.

When the repeat is started, it is checked every time the output is performed to see if the automatic repeat end condition is satisfied (step 250). If the automatic repeat end condition is satisfied, the repeat is ended even if the key is kept depressed, and the next input is waited for (steps 250 → 210). If they do not match, the repeat is continued, and it is confirmed whether the key press is released (steps 250 → 260). If the key press is released, the repeat is terminated and the next input is waited (steps 260 → 210). If the key press is continued, the repeat is continued (steps 260 → 240).
As a result, the repeat is continued until the automatic repeat end condition is met or the key is released.

As described above, the possibility of starting a repeat for an unintended input is reduced, and data can be protected from malfunction by avoiding excessive repeat.

[0038]

Next, the operation of one embodiment of the first embodiment of the present invention will be described in detail with reference to FIGS.

Here, the repeat start condition is that the same key is input twice or more within a specified time, and the repeat automatic end condition is that the repeat is performed up to a specified number of times.

For example, a case will be described in which the upper limit of the number of repeats is 100, the input acceptance time is 0.5 seconds, and the "A" key is kept pressed when the input key was "Z" last time.
First, the previously input key “Z” is compared with the currently input “A” (step 221 in FIG. 5). Since the conditions are different, the previous input key is rewritten to "A" (step 22).
2) Output "A" once (step 230) and wait for the next input (step 210).

Next, if the "A" key is kept depressed once more than one second after the "A" key is released, the previous input key "A" and the currently input "A" are A comparison is made (step 221). Since the conditions are met, it is next checked whether the input was within the designated time (step 223). Here, since the button is not pressed within the designated time from the previous input, "A" is output once (step 230) and the next input is waited for (step 210).

Next, a case will be described in which the "A" key is kept depressed again within 0.5 seconds after the "A" key is released. First, the previously input key "A" is compared with the currently input "A" (step 221). Since the conditions are met, it is next checked whether the input was within the designated time (step 223). Since the button was pressed within the designated time from the previous input, repeat output is started (step 24).
0). Thereafter, it is confirmed that the key press is released (step 260), or "A" is repeatedly output until the number of repeats reaches the specified upper limit (steps 251 → 252).

As described above, in the first embodiment of the present invention, the repeat does not start unless the input matches the condition and matches, so that the probability of an unintended repeat start can be reduced. Even if an unintended repeat occurs, an excessive repeat can be prevented by setting the automatic repeat end condition.

[Other Embodiments of the Present Invention] In the first embodiment, an example in which the repeat start condition and the automatic stop condition are set at the same time has been described. However, depending on the situation, only one of the conditions may be applied. The conditions may be partially set, such as being applied only to a specific key.

Further, a plurality of conditions may be prepared and selected.

The conditions may be not only those based on a specific key input method, but also conditions such as a combination with another input device, a combination of a plurality of keys, a time limit, and the like. The present invention is not limited to key input but can be applied to any input device having a function equivalent to auto repeat. When applied to a mobile terminal or the like, it can also be used as a part of a function for preventing unnecessary power consumption.

[0047]

The first effect is that the possibility of starting a repeat for an unintended input can be reduced. The reason is that the repeat start condition can be made variable to set a condition that is unlikely to occur accidentally.

The second effect is that data can be protected from malfunction due to excessive repetition.

The reason is that an upper limit is set for the number of repeats,
This is because excessive repetition can be prevented.
