Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a computer device having, for example, a display device and an input device provided on the display surface, and inputting is performed by pointing on the display surface with a pen. It relates to the control method.

[0002]

2. Description of the Related Art For example, a computer apparatus having a display device and an input device provided on the display surface, and inputting by pointing the display surface with an attached pen or the like has been implemented. There is. In such a computer device, for example, when activating an arbitrary process, an icon corresponding to the process is displayed on the display surface, and by pressing the position of this icon with a pen, this instruction is input and the process is activated. It is supposed to be done.

However, when such an instruction is made with a pen, in the configuration of the display device and the input device provided on the display surface as described above, a cover glass or the like is interposed between the display device and the input device. Therefore, parallax may occur between the display device and the input device. Therefore, even if the user intends to hold the position of the desired icon with the pen, the computer device may mistakenly recognize the position of another icon, and undesired processing may be activated.

In this case, in general, in order to stop the process, it is necessary to perform the process of stopping after the process is activated and is in the execution state. For this reason, in a process in which a large amount of data is scanned at the time of startup, it takes a long time to start, and other processes cannot be started during this period, so the time required for this startup is wasted at all.

On the other hand, for example, in a desktop computer device, there is a method of inputting a code signal or the like for stopping the processing from a keyboard or the like so that the processing can be stopped by this input. However, in the above-mentioned pen-input computer device, there is no keyboard for inputting code signals and the like, and even if the keyboard is connected, it is not easy to change the pen and operate the keyboard, and it takes time to operate. There is a risk of hanging.

Further, for example, in a desktop computer device, a method is also employed in which a plurality of switches are provided in the computer device main body so that the processing can be stopped when these switches are simultaneously operated. However, in the above-mentioned pen-input computer device, it is difficult to provide such a plurality of switches because downsizing is taken into consideration. Further, similarly to the above, it is not easy to change the pen and operate the switch, and the operation may take time.

Further, a program for stopping the process is provided at the beginning of the program for the process to be started, and for example, a stop icon is displayed on the display surface so that the process can be stopped when this icon is designated. There is also a way to do it.
However, a program for stopping such processing is a special program, and is limited to a specific processing such as a processing predicted to have a long processing time, and is provided for all processing. It wasn't something.

Further, in such a cancellation process, for example, the above-described cancellation icon is displayed at a position apart from the icon for selecting the process. In addition, the code signal for stopping and the plurality of switches provided on the main body all require a special operation from the user. These are protective measures to prevent the processing that has been started correctly from being inadvertently stopped, but all of them are things that the user cannot easily operate, and there is a risk that the operation will take time. .

[0009]

The present application was made in view of the above-mentioned problems, and the problem to be solved is to easily stop a process that is erroneously started in a conventional device or It cannot be interrupted, and on the other hand, it is necessary to prevent such processing from being stopped or interrupted inadvertently.

[0010]

Therefore, in the present invention, by writing a predetermined stroke with a pen on a symbol displayed when a process is started, the started process is stopped or It is designed to be interrupted.

[0011]

According to this, it is possible to stop or interrupt the erroneously started process by a simple operation and prevent the process from being inadvertently stopped or interrupted.

Further, FIG. 3 shows a functional block diagram of an example of processing for realizing the computer device according to the present invention.

In FIG. 3, reference numeral 30 shows a configuration of a main part of a computer device in which an input is provided by pointing an input device provided on a general display surface with a pen. The structure 30 includes a stroke buffer 31 for storing information on the time when the pen 13 is pressed and handwriting (point sequence), system data 32 showing a data group such as graphic data displayed on the display surface, A task control unit 33 and the like that perform procedures for executing and controlling computer processing are provided.

Further, the above-mentioned apparatus is provided with a stroke processing section 40, and the stroke processing section 40 is provided with a stroke monitoring section 41 and a stroke recognizing section 42. The stroke monitoring unit 41 is supplied with the stroke data from the buffer 31, the position data of the above-mentioned symbol S from the system data 32, the process list of the process 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.

Further, the stroke recognition section 42 is provided with a database 50 for defining strokes.
And the stroke definition part 51 in this database 50
A stroke to be recognized is defined by the parameter definition unit 52 and the stroke recognition unit 4 according to this definition.
The stroke recognition at 2 is performed. Further, the code of the recognized stroke is converted into the code of the processing requested by the correspondence table 60, and the processing code is supplied to the task control unit 33.

In this apparatus, the stroke processing section 40 performs processing as shown in the flowchart of FIG. 4, for example. It should be noted that this flow chart is managed on the operating system of the apparatus, including each routine described later.

In FIG. 4, the flow chart is started when the pen 13 included in the structure 30 is brought into contact with the input tablet 12, and the routine of the monitoring section 41 (FIG. 5 described later) is called in step [41]. Further, in step [42], the return value (starting signal) from the monitoring unit 41 is discriminated, and if this value is not "1", the processing is ended.

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]. Further, 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 ended.

Further, in the routine of the monitoring section 41 described above,
The processing is performed as shown in the flowchart of FIG. That is, in FIG. 5, when this routine is started, in step [51], the 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. .

Next, at step [52], the initial state (i =
1) and increment (i = i + 1) are set. Then, 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 result is NO in step [54], the end condition (i = n) is set in step [55].
2] to [55] are repeated by the loop.

If YES in step [54], the return value is set to "1" in step [56], and the process ends. When the end condition (i = n) is satisfied in step [55], the return value is set to "0" in step [57] and the process is ended. In this way, the return value (starting signal) from the monitoring unit 41 in the above step [42] is formed.

Further, in the routine of the recognition section 42 described above,
The processing is performed as shown in the flowchart of FIG. That is, in FIG. 6, when this routine is started, first, in step [61], each parameter of the stroke in the stroke buffer 31 is calculated by referring to the parameter definition section 52 in the stroke definition database 50.

Next, in step [62], the database 50
By referring to the conditional terms of each stroke definition, which will be described later, of the stroke definition unit 51 in the above, a score indicating what percentage of the conditional terms of each stroke is matched is calculated for all the stroke definitions. Then, in step [63], step [6]
It is determined whether or not the highest score calculated in 2] is greater than or equal to p (constant). If there is no more than p,
In step [64], a return value (Null) indicating that there is no corresponding item is formed, and the process is ended.

If the score calculated in step [63] is greater than or equal to p, the object in which the stroke is written is recognized by referring to the target item described later in the stroke definition section 51 in step [65]. To be done. Further, in step [66], the requested processing code is retrieved from the above-mentioned correspondence table 60 using the stroke name (shape code) having the highest score as a key.

Then, in step [67], step [6
6] and the processing code retrieved in step [65] are paired with the stroke written object recognized in step [65] to form a return value, and the processing is terminated. In this way, the recognition unit 42 recognizes the shape and position of the stroke written on the input tablet 12 by the above-described pen 13, and the processing code corresponding to the recognized return value is supplied to the task control unit 33.

Further, FIG. 7 shows an example of definitions used when recognizing the above-mentioned zigzag stroke J. Here, the condition term is divided into, for example, a constant part, a target part, and a condition part.

In this condition section, n in the first line indicates the number of stroke vertices, and the condition is that this number n is N or more. Further, 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. Further, H in the third row indicates a distance connecting two continuously formed vertices, and the condition is that the difference between the maximum value (max) and the minimum value (min) of this distance H is d or less. . In addition, 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 coordinates [Center (Symbol ID)] of the symbol S is D or less for all the vertices.

Further, among the above conditions, N, α, β,
The values of d and D are determined by the constant part, for example N = 2, α =
It is set to 0, β = π / 4, d = 10, and D = 30.

Then, each of these conditions is weighted, and when the conditions are matched, these weighted values are added, and the sum is used as the score of the matching in the above step [62]. That is, for example, when the condition shown in the above condition section has the highest score, the written stroke is recognized as the above-described zigzag stroke J, and the shape code of the recognized stroke J is formed. It

In the target portion of the above-mentioned conditional terms, for example, a region including x% or more of the stroke point sequence is targeted. The value of x is determined by the constant part, for example, x = 70. As a result, the object (symbol S) in which the stroke is written in step [65] is recognized.

Therefore, the above correspondence table 60 is searched by using the shape code of the recognized stroke J as a key, and, for example, when the recognized stroke is the above stroke J, a processing code for ending the process corresponding to the symbol S. Is formed. Then, the process code and the object (symbol S) in which the stroke J is written are supplied to the task control unit 33, and the process corresponding to this symbol S is terminated.

Thus, according to the above-mentioned computer device, the control section 33 for executing the processing, the graphic data section 32 for forming the display on the display surface, the buffer section 31 for storing the written stroke, and the stroke shape. , A recognition unit 40 that determines whether the stroke stored in the buffer unit matches the definition of the definition unit, and a conversion unit 60 that converts the judgment of the recognition unit into an arbitrary instruction code. When the recognition unit determines that the stroke matches the definition, it is mistakenly started by a simple operation by supplying the control unit with an instruction code that stops or interrupts the process being executed. The processing can be stopped or interrupted, and the processing can be prevented from being inadvertently stopped or interrupted.

Further, the definition of the shape of the stroke is such that there is an arbitrary number (N = 2) or more of acute-angled vertices (N = 2), which are equal to or less than an arbitrary angle (β = π / 4), and the display range of the symbol of the stroke is defined. The portion that overlaps with any ratio (x = 70
%) Above, for example, the zigzag stroke J can be accurately recognized, and the zigzag stroke which is intuitive but not normally performed makes it possible to carelessly stop or interrupt the processing. It is something that can be avoided.

Further, since the operation is managed by the operating system, it is possible to equally stop or interrupt all the processes.

In the above-described embodiment, the definition of the stroke J shown in FIG. 7 is an example, and may be arbitrarily changed according to the accuracy required for recognition and the relationship with other used strokes. It Further, in the above-mentioned embodiment, by dividing the definition database into the above-mentioned condition part, target part and constant part, the definition can be easily changed, and these conditions and constants can be stored in the entire database. On the other hand, it can be set to a general purpose.

[0050]

As described above, according to the present invention, it is possible to stop or interrupt a process that has been erroneously started by a simple operation and prevent the process from being stopped or interrupted carelessly. Became. Further, since the operation is managed on the operating system, it becomes possible to stop or interrupt all the processes equally.
