Abstract

PROBLEM TO BE SOLVED: To enable a user handicapped in the sight to easily and surely execute a desired command in an information processor such as a computer. SOLUTION: When the fact of keying is reported from a key input accepting part 201, first of all, a command execution control part 205 refers to a setting file held in a file storage part 200 beforehand. When a double keying system is adopted as an operating system of the pressed key, a clock part 202 is instructed to count the lapse of time after keying and a file read part 203 is instructed to read the name and the explanation of a command assigned to the relevant key. Afterwards, when new keying is reported from the key input accepting part 201, only when the same key is pressed within a prescribed time after first keying, a command execution part 204 is instructed to execute the command assigned to the relevant key.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a command execution device that executes a command assigned to a pressed key, a command execution method, and a program that causes a computer to execute the method.

[0002]

2. Description of the Related Art The user interface of a personal computer has undergone a major transformation from a character-centered CUI to a graphic (image) -centered GUI, and now every command to a computer requires a mouse click at a predetermined position on the screen. It can be executed by intuitive operations such as.

However, the GUI, which is generally easy to understand and easy to use, is not always so for the visually impaired user. Since these users cannot visually check the screen position of the mouse pointer, they generally use software generally called "screen reader". A screen reader is software that reads out aloud the command selected in the menu, the button in focus in the dialog, or the character string input by the user. A typical product is Kochi Corporation. System development "PC-Talker"
and so on. By using this screen reader in combination with general word processing software or the like, the user can execute various processes while confirming them with their ears.

[0004]

However, there has been a problem that the work for executing the operation is complicated or complicated and is difficult for a beginner to use. For example, in order to search for a character string in "Microsoft Word", the user can select a favorite one from the following procedures (1) to (3), but each procedure has the following advantages and disadvantages.

"Alt""→" ... "↓" ...
When you press the "Enter" Alt key, the leftmost one of the menus placed in the toolbar will be in the selected state, and you can hear the sound "File F" that reads its name and so on. Move in the toolbar to a position where you can hear "Edit E". Then, when you press the down arrow key at that position, the commands in the edit menu are displayed in a list in the drop-down list. Then, press the down arrow key to move to the position where you can hear "Search F". Press the Enter key at that position. This procedure relies on voice to reach the target command by groping, so it is suitable for beginners without having to completely memorize which command is where. However, since it is necessary to move to the desired command one by one using the up, down, left, and right arrow keys while listening to the voice, the operation takes time and effort. In addition to well-known processes such as search, there are some commands whose processing contents cannot be predicted only by reading the command name.For such commands, you have to open a separate help and read the relevant part. , Furthermore, the arrival of the target command will be delayed.

"Alt + E""↓" ... "Ente"
r ”Press the Alt key and E key at the same time to display a list of commands in the edit menu, then press the arrow keys to move to a position where you can read" Search F, "and then press the Enter key. To do. In this procedure, the right and left arrow keys are not used, and thus the target command is reached faster. However, this operation is difficult for a user who is not familiar with Windows (registered trademark), and it is difficult for a user who is not familiar with a keyboard to accurately know the position of the Alt key. There will be many mistaken operations. In addition, it is the same as that it is troublesome to refer to the help.

"Alt + E""F" By pressing the Alt key and the E key at the same time, a list of commands in the edit menu is displayed, and then the F key assigned to the search command is pressed. With this procedure, the arrow keys up, down, left, and right are not used at all, so the target command can be reached even faster than, but there is a drawback that it is difficult for beginners to use.

"Ctrl + F" The shortcut key assigned to the search command, that is, the Ctrl key and the F key are pressed at the same time. ~
Although the operation is faster compared to, it is not suitable for users other than users who are proficient in touch typing, in addition to the same drawbacks as described in, and because the commands executed like ~ cannot be confirmed by voice. Is.

The present invention has been made in view of the above problems of the prior art, and it is a command execution device capable of easily and reliably executing a desired command even by a visually impaired user. , A command execution method and a program for causing a computer to execute the method.

The series will be installed and the “Yomer Ver. 5 ”application software is installed. This "Yomail" is software for making a computer function as a kind of reading machine. It takes in a paper image of printed matter (books, passbooks, etc.) set on a scanner, identifies each character in the image, and makes a sound. It has a function to read aloud.

Next, FIG. 2 is an explanatory diagram showing the functional configuration of the command execution device according to the embodiment of the present invention. As shown in the figure, this device includes a file storage unit 200, a key input receiving unit 201, a clock unit 202, and a file reading unit 2.
03, a command execution unit 204, and a command execution control unit 205. However, in the figure, only the minimum functional units for explaining the invention described in the claims are shown, and other functions of the present device are omitted.

In FIG. 2, a file storage unit 200 holds a setting file referred to by a command execution control unit 205, which will be described later, and a plurality of help files read by a file reading unit 203, which will be described later. .

FIG. 3 shows a setting file (“AKIM. $$$”) stored in the file storage unit 200. Incidentally, AK
IM is the Media Keyboard Inte
FIG. 3 is an explanatory diagram schematically showing the content of “(Rface Manager)”. The individual setting contents will be sequentially described with reference to FIG.

(1) The name of the key to which the key command is assigned. Not limited to one key, one command may be assigned to a plurality of keys pressed simultaneously. On the contrary, a plurality of commands may be assigned to one key, or different commands may be assigned depending on the mode described later. In addition, in the "Yomer", even the beginners can easily grasp the key positions, and assign frequently used commands mainly to the function keys and numeric keys.

(2) Command ID This is the ID (serial number) of the command assigned to each key. Note that, in FIG. 3, for easy understanding, the name of the command specified by the ID is shown in parentheses next to the ID, but in the actual file, this name is described as a comment (comment).

(3) File This is the name of a help file read by a file reading unit 203, which will be described later, prior to the execution of each command. FIG. 4 is an explanatory diagram schematically showing the contents of the help file held in the file storage unit 200. As shown in the figure, in principle, the corresponding command name 400 and the command description 401 are sequentially described in the text. However, exceptionally, for commands for switching various settings, the command name 400 The name 402 of the variable in which the command stores the setting value is described before. The variable name 402 is replaced by the value of the variable at that time at the time of reading and is uttered. The extension of the help file is ". akh ”, but the format is normal plain text.

(4) Mode This is a mode in which each command can be executed. "Yomail" has a reading mode that allows you to read (or rather read) the read documents, an edit mode that allows you to edit in addition to the reference, and an FD book for browsing electronic books in a special format called the FD book. There are multiple modes, such as modes, and the commands that can be used are different for each mode. For example, according to the setting file of FIG. 3, "Reading stop" (ID = 47) can be used in all modes, but "Switch to edit mode" (ID = 75) and "Switch to reading mode" (ID = 76) can be used only in the reading mode and the editing mode.

(5) Operation method In order to execute the command assigned to each key,
These are the operation methods of each key, and there are the following four types.

When the key is pressed once, the command assigned to the key is immediately executed. In the actual setting file, it is represented by a character string "one" (meaning one-click or one-touch). For example,
In the case where the setting file is as shown in FIG. 3, to execute the "speech stop" command (that is, to stop the sound being read), the Shift key needs to be pressed only once.

When the double-press key is pressed, first the name of the command assigned to the key and its description (may be called the text of the help file associated with the key) are read aloud,
This is a method in which the command is executed only when the same key is pressed again within a predetermined time. In the actual setting file, it is represented by the character string "double" (meaning double-click).

For example, when the setting file is as shown in FIG. 3, if the Ctrl key and the J key are pressed at the same time, first the name of the command assigned to the key is "Notice of current position". Read aloud. Then, after the pause (between) described later, the explanation of the above command is read aloud such as "I will tell you the current cursor position by voice like page, line, digit, etc.". However, if you press the Ctrl key and J key again at the same time within a predetermined time after the key is pressed, specifically, until the time limit described later, the reading is interrupted and the "current position notification" command is issued. Execution is performed, and a voice notification of the cursor position is given as in "The current position of the cursor is at page 13, line 13, column 25."

When the toggle method key is pressed, any one of the plurality of commands assigned to the key is immediately executed. In the actual setting file, it is represented by the character string "tog" (meaning "toggle"). This method uses commands for switching various settings among the keys (specifically, the above-mentioned mode switching, reading speed / reading speed /
It is adopted for each assigned key, such as switching the reading voice.

For example, if the F7 key is pressed once when the setting file is as shown in FIG. 3, if the current mode is the reading mode, "switch to edit mode".
The command (ID = 75) is executed, and the mode after switching is uttered like "edit mode". Then, when the F7 key is pressed again, the "switch to reading mode" command (ID = 76) is executed, and the mode after switching is uttered as "reading mode". In this state, if the F7 key is pressed once more, the edit mode is entered, and thereafter the setting can be cyclically changed in the same manner.

This method is essentially similar to that described above in that the command is executed each time a key is pressed. Alternatively, this may be considered a special case, especially for keys assigned multiple commands.

In principle, in this method, each time a key is pressed, a plurality of commands assigned to the key are sequentially executed. However, in an actual product, the command is exceptionally limited only when the first key is pressed. Does not execute, but only reads out the text of the help file associated with the key. That is, when the F7 key is pressed in the reading mode as in the above, only the "reading mode" and the current mode are read first. Then, if you don't press the key as it is, after the pause described later, the command name is the same as if you did not press any key, such as "Reading and switching of edit". , Or use to input characters .... "is read aloud in sequence. However, if you press the F7 key again from the time of the first press to the time limit described below, the reading is interrupted and the "switch to edit mode" command is executed, resulting in a switch to "edit mode". The current mode after is announced.

This method (which is a variation of this method and henceforth called ') is similar to the above in that the command is not executed unless the key is pressed twice at the beginning, and thereafter, the command is executed each time the key is pressed. Is similar to that described above. In this way, special handling only for the first time is often necessary to check what the current setting value is when changing various setting values, so it is easy to confirm it in the process of executing the setting switching command. This is so that it can be done.

When the toggle plus enter system key is pressed, the name and description of any one of the plurality of commands assigned to the key (the text of the help file associated with the key may be said. )
Is read out, and when the enter key is pressed, the read out command is executed. In the actual setting file, it is represented by a character string "togcom" (meaning a toggle command). This method is adopted especially for keys to which a plurality of commands of the same kind are assigned.

For example, if the setting file is as shown in FIG. 3, the F3 key is a command related to search "search next" (ID = 105) "search previous" (ID = 164). "Starting from the beginning and searching" (ID
= 165) "Search starting from the end" (ID = 166)
4 commands are assigned. And F3
When the key is pressed once, the name of the first command is read aloud, such as "Find Next", and after the pause described below, the explanation is "Search for a character string from the current position of the cursor toward the end of the document." Will be read. "

Here, within a predetermined time after pressing the F3 key,
Specifically, enter before the time limit described below.
When the r key is pressed, the "search next" command is executed, and as a result, a dialog for specifying the search character string is displayed on the screen. On the other hand, if the F3 key is pressed again within the above-mentioned predetermined time, the name of the next command assigned to the key is read aloud as "Find Previous", and further explanation is given after the pause described below. A text string is searched from the current position of the cursor toward the beginning of the document. "

Then, if the Enter key is pressed within a predetermined time from the second pressing of the F3 key, the "search previous" command is executed, and if the F3 key is pressed, the "Search from the beginning" command is executed for the next command.・ ・ ・ (Pause) ・ ・ ・ Searches from the beginning of the document toward the end of the document. "
The name and description are read aloud like this.

In this way, the second pressing of the same key is interpreted as a command execution instruction in the above, whereas
Is interpreted as an instruction to switch to the subsequent command.
er key). However, this is due to the difference that the number of commands assigned to a key is one, whereas there is more than one, and after reading the command name and description with the first key operation, Two
The essence of executing the command by the key operation of the second time is the same. Therefore, can also be considered a special case of being employed for keys to which more than one command has been assigned.

As described above, the key operation methods are roughly classified into
Command is executed by pressing the key once ()
In some cases, the command is not executed unless the key is pressed twice (). The principle of the operation method in the present invention is the latter (among others), and as an exception, careless execution is performed, such as a command that needs to be executed particularly quickly, such as reading stop, or switching of various settings. However, the former is adopted for commands that do not significantly hinder work (commands that do not involve difficult processing to restore the original state, such as moving the cursor and destroying data).

(6) Pause Time The description of the remaining items of the setting file shown in FIG. 3 will be continued. Next, the pause time refers to the pause time from the reading of the command name by the file reading unit 203, which will be described later, to the start of reading the description, and the reading of the current set value. It is the pause time from the start of reading the command name. In the example of FIG. 3, since it is set to 500 milliseconds, for example, after reading the “current position notification” and the name of the command, a silent period of 5 seconds is set,
"The current cursor position will be announced by voice, such as page number, line, and digit."

(7) The meaning is slightly different depending on the time operating method up to the time limit. First, the time until the time limit in the above and'is the length of time during which the second key operation is interpreted as a command execution instruction when the key to which the command is assigned is pressed twice in succession. (Note that the starting point of the time is the time of the first key operation). In the example of FIG. 3, the time is set to 5000 milliseconds, so if the time between pressing the Ctrl key and J key at the same time again is within 50 seconds, the "current position notification" command is executed. On the other hand, if there is a delay of 50 seconds between the first time and the second time, the name and description of the "current position notification" command is read again.

The time to the time limit in the above is the key to which the command is assigned, followed by E.
When the enter key is pressed, the second key operation is interpreted as a command execution instruction, and when the key to which the command is assigned is pressed twice in succession, the second key operation is pressed. Is the length of time during which the key operation is interpreted as a command switching instruction (in each case, the starting point is the time of the first key operation). For example, if you press the Enter key within 50 seconds after pressing the F3 key, the first "Find Next" command assigned to the F3 key will be executed, and if you press the F3 key twice within 50 seconds, the second You will hear the name and description of the "Find Previous" command.
It should be noted that the above-mentioned operation method has no concept of time limit.

Returning to FIG. 2, the description of the remaining functional units will be continued. Note that the functional units described below are all HD1
This is realized by the CPU 101 executing various processes under the control of "Yomail" read from the RAM 05 into the RAM 103. The command execution control unit 205, which is the core of the present invention, is realized by a DLL file (“AKIM.dll”) originally developed by the applicant. In addition to the HD 105, this program can be recorded in any computer-readable recording medium such as the FD 107, the CD-ROM 109, the MO, and the DVD, and can be distributed by the medium. It is also possible to distribute via a network (transmission medium) such as the Internet.

In the figure, reference numeral 201 denotes a key input acceptance unit, which accepts a key input from the user through the keyboard 112 and outputs which key is pressed to a command execution control unit 205 described later. Reference numeral 202 denotes a time counting unit, which receives an instruction from a command execution control unit 205 described later, measures the time by a timer held therein, and outputs the measured time to the command execution control unit 205. 203
Is a file reading unit, which receives an instruction from a command execution control unit 205, which will be described later, converts the body of the designated file into voice data and outputs the voice data from the speaker 111. A command execution unit 204 executes a designated command in response to an instruction from a command execution control unit 205 described later.

Next, 205 is a command execution control unit, which controls the time counting unit 202, the file reading unit 203, and the command execution unit 204 in accordance with the operation method of the key input from the key input reception unit 201, and the command execution control unit 205 shown in FIG. Each processing shown in each figure of FIG. 8 is performed. Hereinafter, they will be sequentially described.

(1) When the operation method of the pressed key is the one-time pressing method ... FIG. 5 When any key is pressed, that is, the information of the pressed key is input from the key input reception unit 201. In that case (step S501 in FIG. 5: Yes), the command execution control unit 205 refers to the setting file in FIG. 3 held in the file storage unit 200. Then, when the pressed key is a key such as the Shift key, which has adopted the one-time pressing method (described above) as the operation method (step S502: Yes), the command execution control unit 205 causes the command execution unit 204 The command assigned to the key in the setting file, for example, "stop reading" is executed (step S503). If the key operation method is other than the one-time pressing method (step S50)
2: No), and shifts to the processing of FIG.

(2) When the operation method of the pressed key is the double-press method ... FIG. 6 The double-press method (described above) is the operation method of the pressed key, for example, Ctrl + J key. When adopted (step S502 in FIG. 5: No, step S in FIG. 6)
(601: Yes), the command execution control unit 205 instructs the clocking unit 202 to start clocking, and the clocking unit 202 receiving this command resets and starts the timer held therein (step S602).

In parallel with the above, the command execution control unit 205 determines the name of the help file associated with the key from the setting file of FIG. 3, for example, "curren".
t. akh ”and the time of the above pose, eg 500
Milliseconds are read and passed to the file reading unit 203 together with a reproduction start instruction. Receiving this, the file reading unit 203 reproduces the name and description of the command described in the body of the help file as a voice with a pause for a designated time (step S6).
03).

On the other hand, the command execution control unit 205 waits for a key input at the same time as a reproduction instruction is given to the file reading unit 203, and when the key input reception unit 201 notifies that a new key has been pressed (step S604: Yes), first. The time measuring unit 202 is instructed to stop the time measuring (step S605), and the file reading unit 203 is instructed to stop the reproduction of the name and the explanation (step S60).
6).

Then, it is judged whether or not the time measured by the timer unit 202 is within a predetermined time, specifically, the time up to the time limit specified in the setting file of FIG. 3, and within the predetermined time. If there is (step S607: Ye
s), and further, it is determined whether or not the second key (the key pressed in step S604) is the same as the first key (the key pressed in step S501 in FIG. 5). If the keys are the same (step S608: Yes
s) The command execution unit 204 is instructed to execute the command assigned to the key in the setting file (step S609).

As described above, only when the same key is repeatedly hit twice within the predetermined time (step S607: Yes,
(Step S608: Yes) When the command is executed and there is a time interval between the first key press and the second key press (Step S607: No), or when the key is different between the first key and the second key ( In step S608: No), the process returns to step S502 in FIG. 5 and the same process as the first key is repeated for the second key.

(3) When the operation method of the pressed key is the toggle method ... FIG. 7 For example, like the F7 key, the toggle method (above ') is adopted as the operation method of the pressed key. If (step S502 in FIG. 5: No, step S60 in FIG. 6)
1: No, step S701 of FIG. 7: Yes), the process of the command execution control unit 205 is as shown in FIG.
It is similar to the case of the push-push method, but in step S6 in FIG.
It is different from FIG. 7 in that the process is ended as it is, but in FIG. 7, the process returns from step S709 to step S702 again.

That is, in the double-pressing method of FIG. 6, the command is completed by executing the second key-pressing, which is the end. In contrast, in the toggle method of FIG. As long as the same key is continuously pressed within a predetermined time after the key is pressed, the commands assigned to the key are executed one by one. As a result, in the toggle method, it is possible to confirm the current setting value and the details of the command with the first key depression, and then to change the setting value continuously with the second and subsequent key depressions.

It should be noted that, in addition to the name and description of the command read aloud by the double-press method, there is a slight difference in that the current set value is read aloud by the toggle method (steps S603 and S606 of FIG. 6, and FIG. Step S703
(Compare S706), which is, as described above in FIG. 4, exclusively for the convenience of the user in view of the peculiarities of the commands (specifically, commands for switching various settings) adopted in the toggle method. Was added for the purpose of measuring
It is not the essential difference between the two.

(4) When the operation method of the pressed key is the toggle plus enter method ... FIG. 8 For example, like the F3 key, the toggle plus enter method is used as the operation method of the pressed key. When (above) is adopted (FIG. 5 step S502: No, FIG. 6 step S601: No, FIG. 7 step S701: No,
The process of the command execution control unit 205 in step S801 in FIG. 8 (Yes) is also similar to the case of the double-press method of FIG. 6 as shown in FIG. 8, but the command is executed by the double-press method is the same. When the key is pressed (step S60 in FIG. 6)
8: Yes), whereas the Enter key is used in the toggle plus enter method (step S80 in FIG. 8).
8: No, step S809: Yes).

When the same key is repeatedly hit in the toggle plus enter method (step S808 in FIG. 8:
Yes), and returns to step S802 to repeat the same processing for the second key as for the first key. However, what is read out in steps S803 to S806 is
It is the name and description of the next command following the command name and description that was read a previous time in the help file (including those that were canceled or omitted when trying to read aloud). Also,
The next command is executed in step S810.

Due to the above difference, even if a plurality of commands are assigned to the same key in the toggle plus enter method, by pressing the key twice each time the commands are sequentially switched and the desired command appears. At that time, the command can be selectively executed by the Enter key. Conversely, because of the existence of this method, multiple commands can be assigned to the same key, the number of keys is insufficient for the number of commands,
It is possible to avoid the complexity of having to memorize the key for each command that is slightly different.

According to the embodiment described above, in principle, the name and detailed explanation are read aloud when a command is executed, so which command is executed even by a visually impaired user and execution You can easily check in advance what command will be executed.
Therefore, it is possible to avoid an erroneous operation caused by an erroneous remembering or typing error of the key, and a complicated work for restoring the original state. Also, if there is no particular need to check,
Since the reading can be stopped or omitted by pressing the same key again, the work can be speeded up and the efficiency can be improved.

Further, although the above-described embodiment is mainly intended for the visually impaired user, even a user who has a complicated hand operation such as simultaneous pressing with the Alt key due to a hand or finger disorder, It is often relatively easy to repeatedly tap the same key (note that users who have difficulty in quick operation are
You can set a long time to the time limit in the setting file). Further, even for a beginner who is not familiar with a computer, the operation procedure of this device is simple and easy to understand, so that the computer can be used with a feeling that is not much different from a CD radio-cassette.

It should be noted that the above-mentioned key input receiving unit 201 is the "first detecting means" and the "second detecting means" in the claims.
In addition, the processing to be performed corresponds to the "first detecting step" and the "second detecting step", respectively. Also,
The time measuring unit 202 corresponds to the "time measuring means" in the claims, and the processing performed by the time measuring unit 202 corresponds to the "time measuring step" in the claims. Further, the file reading unit 203 corresponds to the "reading unit" in the claims, and the processing performed by the file reading unit 203 corresponds to the "reading step" in the claims. Further, the command executing unit 204 corresponds to a “command executing unit” in the claims, and the processing performed by the command executing unit 204 corresponds to a “command executing step” in the claims. Further, the command execution control unit 205 corresponds to the “first determining unit” and the “second determining unit” in the claims, and the processing to be performed includes the “determining step” in the claims.

Further, in the claims, "execute the command assigned to the key whose pressing is detected ..."
Specifically, it is assumed that a command is assigned to a single key, such as the Shift key, the F7 key, or the F3 key described above. On the other hand, “execute a command assigned to a combination of keys detected as pressed” means that a plurality of keys (two in this example, but three or more) are used as in the Ctrl + J key described above. It may be a key of)), assuming that a command is assigned to simultaneous pressing.

[0065]

As described above, according to the present invention, when the depression of at least one of the plurality of keys is detected, the name and description of the command assigned to the depressed key or key combination is first displayed. When reading aloud and then detecting a further key press, the time from the detection of the previous press to the detection of the subsequent press is less than a predetermined time, and the pressed key or key combination is the same before and after. In this case, since the command assigned to the key or the combination of keys is executed, the name and description of the command can be confirmed by voice by pressing the single or multiple keys to which the command is assigned once. At the same time, by pressing the button twice without leaving too much space, you can cancel or skip the confirmation and execute the above command. Even impaired users easily and reliably desired command can be run command execution device, an effect that a program for executing the command execution process and method on a computer can be obtained.
