Description

[0001]
[Industrial application fields]
The present invention relates to a computer device having, for example, a display device and an input device provided on the display surface, and an input is performed by instructing the display surface with a pen, and a control method therefor. .
[0002]
[Prior art]
For example, a computer device is implemented which has a display device and an input device provided on the display surface, and performs input by instructing the display surface with an attached pen or the like. In such a computer device, for example, when starting an arbitrary process, an icon corresponding to the process is displayed on the display surface, and the instruction is input by pressing the position of the icon with a pen to start the process. It has come to be.
[0003]
However, in the case where such a pen instruction is given, in the configuration of the display device as described above and the input device provided on the display surface, a cover glass or the like is interposed between the display device and the input device. There is a risk that parallax occurs between the display device and the input device. For this reason, even if the user intends to hold the position of a desired icon with a pen, the computer device side may misunderstand that it is the position of another icon, and an undesired process may be started.
[0004]
In this case, in general, in order to cancel the processing, it is necessary to perform the cancellation processing after the processing is started and is in an execution state. For this reason, in a process that scans a large amount of data at the time of activation, it takes a long time to activate, and during this time other processes cannot be activated, so that the time required for this activation is completely consumed.
[0005]
On the other hand, for example, in a desktop computer device, there is a method in which a code signal or the like for stopping the process is input from a keyboard or the like, and the process can be stopped by this input. However, in the above-described pen input computer device, there is no keyboard for inputting a code signal or the like, and even if the keyboard is connected, it is not easy to move the pen and operate the keyboard, and the operation takes time. There is a risk of hanging.
[0006]
In addition, for example, a desktop computer apparatus employs a method in which a plurality of switches are provided in the main body of the computer apparatus so that processing can be stopped when these are operated simultaneously. However, in the above-described pen-input computer device, it is difficult to provide such a plurality of switches because downsizing is originally considered. Similarly to the above, it is not easy to change the pen and operate the switch, and there is a possibility that the operation takes time.
[0007]
In addition, there is a method of providing a program for stopping processing at the beginning of the processing program to be started, for example, displaying a stop icon on the display surface, and allowing the processing to be stopped when this icon is instructed. is there. However, a program for canceling such processing is special, and is employed only for specific processing such as processing that is predicted to have a long processing time, and is provided for all processing. It was not a thing.
[0008]
In such a cancellation process, for example, the above-described cancellation icon is displayed at a position away from the icon for selecting the process. The above-described code signal for canceling and the plurality of switches provided on the main body all require a special operation from the user. These are protective measures to prevent inadvertently canceling a process that has been started correctly, but none of them can be easily operated by the user and may take a long time to operate. .
[0009]
[Problems to be solved by the invention]
The present application has been made in view of the above points, and the problem to be solved is that the process that has been erroneously started cannot be easily stopped or interrupted by the conventional apparatus, while this It is necessary to prevent such processing from being stopped or interrupted inadvertently.

[0018]
For example, when an arbitrary process is started for such a computer apparatus, icons I corresponding to the respective processes as shown in FIG. 2A are displayed on the display surface of the display unit 9 described above. The Then, by designating an arbitrary icon I using the pen 13, for example, the designated icon I is enlarged B as shown in FIG. 2B, and a desired process is started.
[0019]
At the same time, as shown in FIG. 2B, for example, a symbol S indicating that processing is in progress is displayed at the position instructed by the pen 13. For example, the symbol S is displayed by using an animation in which a figure that is alternately colored by dividing the circle into four as shown in the figure rotates.
[0020]
In the computer device control method of the present invention, a predetermined stroke J as shown in FIG. 2C, for example, is written using the pen 13 to the input tablet 13 corresponding to the symbol S on the display unit 9. Thus, the activated process is stopped or interrupted.
[0021]
That is, in the above-described apparatus, for example, in the process of the document creation function, a process such as insertion at this position can be executed by writing a bowl-shaped stroke in the middle of the input character string. Yes. Therefore, the above-described predetermined stroke J can be recognized using such a stroke recognition function, and the above-described activated processing can be stopped or interrupted by this recognition.

[0025]
In the above-described apparatus, for example, when it is desired to resume the interrupted processing, the same icon I is pressed again with the pen 13, an arbitrary return stroke is written, or a dedicated key switch is provided for the operation. Can be resumed by. The stroke input method is not limited to the combination of a doublet and a pen as described above, and may be performed using a mouse or the like.
[0026]
Further, FIG. 3 shows a functional block diagram of an example of processing for realizing the computer apparatus according to the present invention.
[0027]
In FIG. 3, reference numeral 30 denotes a configuration of a main part of a computer device in which input is performed by pointing with a pen an input device provided on a general display surface. The configuration 30 includes a stroke buffer 31 for storing information on the time when the pen 13 is pressed and handwriting (dot sequence), system data 32 indicating a data group such as graphic data displayed on the display surface, A task control unit 33 and the like for performing procedures for computer processing and control are provided.
[0028]
Further, the stroke processing unit 40 is provided in the above-described apparatus, and the stroke monitoring unit 41 and the stroke recognition unit 42 are provided in the stroke processing unit 40. The stroke monitoring unit 41 is supplied with the stroke data from the buffer 31, the data on the position of the symbol S from the system data 32, the process list of the processing being executed from the task control unit 33, and the like. Then, the activation signal detected by the monitoring unit 41 and necessary data are supplied to the stroke recognition unit 42.
[0029]
Further, the stroke recognition unit 42 is attached with a database 50 for defining strokes. A stroke to be recognized by the stroke definition unit 51 and the parameter definition unit 52 in the database 50 is defined, and the stroke recognition unit 42 recognizes the stroke according to this definition. Further, the recognized stroke code is converted into a processing code requested by the correspondence table 60, and this processing code is supplied to the task control unit 33.
[0030]
In this apparatus, the stroke processing unit 40 performs processing as shown in the flowchart of FIG. This flowchart is managed on the operating system of the apparatus including each routine described later.
[0031]
In FIG. 4, the flowchart starts when the pen 13 included in the configuration 30 is brought into contact with the input tablet 12, and a routine (FIG. 5 described later) of the monitoring unit 41 is called in step [41]. Further, in step [42], the return value (activation signal) from the monitoring unit 41 is determined. If this value is not "1", the process is terminated.
[0032]
When the return value is “1” in step [42], the routine of the recognition unit 42 (FIG. 6 described later) is called in step [43]. Furthermore, in step [44], the return value (processing code) from the recognition unit 42 is returned to the task control unit 33 of the configuration 30, and this processing is terminated.
[0033]
Further, in the routine of the monitoring unit 41 described above, processing is performed as shown in the flowchart of FIG. That is, in FIG. 5, when this routine is started, a list P = {p ₁ , p ₂ ... P _n } of processes currently being executed is received from the task control unit 33 of the configuration 30 in step [51]. .
[0034]
In step [52], an initial state (i = 1) and an increment (i = i + 1) are set. In step [53], NumS _i (the number of point sequences existing on the symbol S _i corresponding to p _i ) is defined, and in step [54], NumS _i > THR (constant) is determined. If the answer is NO in step [54], an end condition (i = n) is set in step [55], and these steps [52] to [55] are repeated by a loop.
[0035]
If the answer is yes in step [54], the return value is set to "1" in step [56] and the process is terminated. If the end condition (i = n) is reached in step [55], the return value is set to “0” in step [57] and the process is ended. In this way, a return value (activation signal) from the monitoring unit 41 in the above-described step [42] is formed.
[0036]
In the routine of the recognition unit 42 described above, processing is performed as shown in the flowchart of FIG. That is, in FIG. 6, when this routine is started, first, the parameter definition unit 52 in the stroke definition database 50 is referred to in step [61], and each parameter of the stroke in the stroke buffer 31 is calculated.
[0037]
Next, in step [62], referring to the condition items of each stroke definition described later of the stroke definition unit 51 in the database 50, the score of what percentage of the condition items of each stroke is matched is obtained for all the stroke definitions. Is calculated. In step [63], it is determined whether or not the highest score calculated in step [62] is equal to or greater than p (constant). If there is no p or more, a return value (Null) indicating that there is no corresponding is formed in step [64], and the process is terminated.
[0038]
If the score calculated in step [63] is greater than or equal to p, in step [65], a target item described later of the stroke definition unit 51 is referred to and the target in which the stroke is written is recognized. Further, in step [66], the requested processing code is retrieved from the correspondence table 60 using the stroke name (shape code) having the highest score as a key.
[0039]
Then, in step [67], a return value is formed by pairing the processing code searched in step [66] and the target in which the stroke recognized in step [65] is written, and the processing ends. In this way, the shape and position of the stroke written on the input tablet 12 by the pen 13 described above are recognized by the recognition unit 42, and a processing code corresponding to the recognized return value is supplied to the task control unit 33.
[0040]
FIG. 7 shows an example of definitions used when recognizing the zigzag stroke J described above. Here, the condition term is divided into, for example, a constant part, a target part, and a condition part.
[0041]
In this condition part, n in the first row indicates the number of vertices of the stroke, and this number n is N or more. Also, θi in the second row indicates the angle of each vertex, and it is a condition that this angle θi is α or more and β or less for all the vertices. H in the third row indicates a distance connecting two vertices formed continuously, and the difference between the maximum value (max) and the minimum value (min) of the distance H is d or less. . Further, Li in the fourth row indicates the coordinates of each vertex, and the condition is that the distance between the coordinates Li and the center coordinate [Center (Symbol ID)] of the symbol S is D or less for all the vertices.
[0042]
Further, in each of the above conditions, the values of N, α, β, d, and D are determined by a constant part. For example, N = 2, α = 0, β = π / 4, d = 10, and D = 30. Determined.
[0043]
Each of these conditions is weighted, and when the conditions are matched, these weighted values are added, and this sum is used as the matching score in step [62] described above. That is, for example, when the condition shown in the above-mentioned condition part is the highest score, the written stroke is recognized as the zigzag stroke J, and the shape code of the recognized stroke J is formed. The
[0044]
In addition, in the target part in the above-described conditional terms, for example, a region including x% or more of the stroke point sequence is targeted. The value of x is determined by a constant part, for example, x = 70. As a result, the object (symbol S) in which the stroke is written in step [65] is recognized.
[0045]
Therefore, the above-described correspondence table 60 is searched using the shape code of the recognized stroke J as a key. For example, when the recognized stroke is the above-mentioned stroke J, a processing code for ending the process corresponding to the symbol S is formed. The Then, the process code and the target (symbol S) in which the stroke J is written are supplied to the task control unit 33, and the process corresponding to the symbol S is completed.
[0046]
Thus, according to the above-described computer apparatus, the control unit 33 that executes processing, the graphic data unit 32 that forms a display on the display surface, the buffer unit 31 that stores the written stroke, and the shape of the stroke are defined. A definition unit 50; a recognition unit 40 that determines whether or not a stroke stored in the buffer unit matches a definition of the definition unit; and a conversion unit 60 that converts the determination of the recognition unit into an arbitrary instruction code. When the recognition unit determines that the stroke matches the definition, it stops the process that was erroneously started by a simple operation by supplying the control unit with an instruction code that stops or interrupts the process being executed. Alternatively, the process can be interrupted, and the process can be prevented from being inadvertently stopped or interrupted.
[0047]
Further, the definition of the stroke shape is a portion where there are an arbitrary number (N = 2) or more of acute vertices that are not more than an arbitrary angle (β = π / 4) in the stroke, and overlap with the stroke symbol display range. Is set to an arbitrary ratio (x = 70%) or more, for example, a zigzag stroke J can be accurately recognized, and an intuitive but not normally performed zigzag stroke is particularly processed. Can be prevented from being inadvertently stopped or interrupted.
[0048]
Furthermore, since the operation is managed on the operating system, the process can be stopped or interrupted equally for all the processes.
[0049]
In the above-described embodiment, for example, the definition of the stroke J shown in FIG. 7 is an example, and is arbitrarily changed according to the accuracy required for recognition, the relationship with other used strokes, and the like. In the above-described embodiment, the definition database is divided into the above-mentioned condition part, the target part, and the constant part, so that the definition can be easily changed, and these conditions and constants are included in all databases. On the other hand, it can be set to general purpose.
[0050]
【The invention's effect】
According to the present invention, it is possible to stop or interrupt the operation launched by mistake by a simple operation, stopping or interruption of treatment can now be prevented performed inadvertently. In addition, since the operation is managed on the operating system, the processing can be stopped or interrupted equally for all the processing.
