Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a data processing apparatus which has a pointing device such as an input pen or a mouse, which is a so-called pointing device, and which can easily process data based on an instruction from the pointing device. .

[0002]

2. Description of the Related Art In a data processing device having a display device, there have been proposed many techniques for scrolling and displaying display data which cannot be displayed on a display screen of the display device at a time by a scroll function of the data processing device. And has already been put to practical use. For example, in the Windows OS of Microsoft Corporation, an icon area for designating execution of scroll processing for scrolling the display data in four directions of up, down, left and right is provided in the peripheral portion of the display screen. A scroll process is executed by instructing by a method such as clicking using an instructing means which is a so-called pointing device. In addition to the icon area, an area called a scroll bar or the like is provided. In the scroll bar area, for example, by dragging the mouse, scroll processing is performed in synchronization with the movement of the mouse. I am trying to do it.

Further, in the data processing apparatus disclosed in Japanese Patent Laid-Open No. 3-30011, an area for designating execution of a scroll function is provided so as to surround a data display area, and a mouse or the like is provided in this area. When the cursor or the like intrudes by operation, the display data is scrolled in a predetermined direction corresponding to the invaded area.

As the pointing device, there is an input pen in addition to a mouse. When an input pen is used, it is generally arranged so that the input surface of an input device, such as a tablet having a translucent input surface, overlaps the surface of the display device. Icons that indicate various data processing are displayed on the display surface. When the operator uses the input pen to specify the input surface that overlaps the icon part displayed on the display surface, the input surface on the input surface specified by the input pen is displayed. Data processing associated with the icon including the coordinate point on the display surface corresponding to the coordinate point is executed. It is also possible to instruct execution of the scroll processing by using such an input pen.

[0005]

In the prior art data processing device, the scroll speed of display data is constant. Therefore, for example, when the operator tries to perform a search while visually following the display data, the scroll speed is improper, and thus a reliable search cannot be performed smoothly. For example, when one display data has a part to be searched carefully and a part to be searched relatively easily, it is possible to search as desired by the operator by keeping the scroll speed constant. I can't.

Further, in the case where the scroll bar area as described above is provided and the scroll processing is executed in association with the movement of the mouse, the size of the moving range of the mouse is changed with the scroll speed kept constant. Or, conversely, it is necessary to change the scroll speed while keeping the size of the mouse movement range constant. Therefore, depending on the size of the display data, fine scrolling cannot be performed and, for example, a problem that sufficient search cannot be performed occurs. Further, since the mouse needs to be moved, the amount of mouse movement may be very large depending on the size of the display data.

When the display data is displayed horizontally, the display data amount in the vertical direction is large and the display data amount in the horizontal direction is often small. In such a case, if the vertical direction and the horizontal direction have the same scroll speed, it is necessary to move the mouse a lot only during the vertical scroll.

Further, it may not be necessary to scroll under the same conditions when the display data is character data and when it is image data such as a figure. For example, in the case of character data, dot-by-dot scrolling is not necessary. In the case of image data, scrolling by row or column is required. Scrolling is unnecessary and dot-by-dot scrolling may be required. Therefore, the conventional data processing device cannot be said to be excellent in operability for the operator.

An object of the present invention is to provide a data processing device having excellent operability, which can process data under a condition desired by an operator by a simple operation.

[0010]

According to the present invention, there is provided a display means having a display surface in which Cartesian coordinates are set, an input means for outputting coordinate points on the display surface designated by the indicating means, and a predetermined display area. In a data processing device including a control means for processing data according to the data processing associated with, the data processing device controls the pressure applied when a point on the display surface is instructed by the instructing means. When the coordinate point output from the input means is within a predetermined display area associated with the data processing, the control means includes pressure detecting means for detecting, based on the detection level of the pressure detecting means. The data processing apparatus is characterized in that the data processing condition is changed. According to the present invention, when the operator designates a point in a predetermined display area associated with the data processing on the display surface by the instruction means, the input means outputs the designated coordinate point on the display surface. To do. The control means processes the data in accordance with the data processing associated with the display area including the output coordinate points, but at this time, the control means controls the detection level of the pressure detecting means, that is, the pressure applied at the time of the instruction by the instructing means. The data processing conditions are changed based on the level. Since the data processing conditions can be changed by the pressure level applied by the operator, there is no need to move the indicating means, and a simple operation allows
The data can be processed under the conditions desired by the operator.

Further, the invention is characterized in that the control means changes the scroll speed of the scroll processing of the display data displayed on the display surface, which is the data processing, based on the detection level of the pressure detecting means. . According to the invention, the data processing is scroll processing of display data, and the scroll speed is changed based on the detection level of the pressure detection means. Therefore, the display data can be scrolled at a scroll speed desired by the operator by a simple operation.

In the present invention, the control means considers characteristics peculiar to the display data such as the size of the display data,
Characterized by changing the scroll speed. According to the present invention, the control means changes the scroll speed in consideration of characteristics peculiar to the display data such as the size of the display data. For example, when the size of the display data is different in the vertical direction and the horizontal direction, even if the same level is detected, the scroll speed is changed in each direction. For example, when the size of the display data is large, the scroll speed is increased, and when the size of the display data is small, the scroll speed is decreased. By changing the scroll speed in this manner, scroll processing can be performed under more preferable conditions, and operability is improved.

Further, the present invention is characterized in that the data processing device includes warning information generating means for generating warning information when the detection level of the pressure detecting means becomes larger than a predetermined threshold value. According to the present invention, by generating the warning information as described above, it is possible to notify the operator that the applied pressure has become larger than a predetermined threshold value. The predetermined threshold value is selected to be a value smaller than the pressure at which the input surface of the input unit pointed by the input pen is broken when the pointing unit is realized by the input pen. This can prevent the data processing device from being mechanically damaged.

FIG. 2 is a plan view showing the display screen 12 of the display unit 3 included in the data processing device 1. FIG. 3 is a cross-sectional view showing the indicating device 9 included in the data processing device 1. The data processing device 1 includes a control unit 2, a display unit 3, a main memory 5, a display data conversion unit 6, an arrangement memory 7, an input unit 8, an indicating device 9, a buzzer 11, a scroll means memory 23 and a weight counter 24. Composed.

Necessary data is read out from the main memory 5 in which the data to be processed by the control unit 2 is stored, to the display data conversion unit 6, and the display data conversion unit 6 is read.
A VR for storing the display data according to the coordinates on the display screen 12 in which the display data created in 1. is set to the orthogonal coordinates.
It is provided to the display unit 3 having an AM (Video Random Access Memory) 4. On the display screen 12 of the display unit 3, the input surfaces of the input unit 8 which are translucent and whose rectangular coordinates are set and which are realized by, for example, doublets are arranged so as to overlap. Data processing by the control unit 2 is set in association with a predetermined area on the input surface of the input unit 8.
The coordinates of the predetermined area are stored in the arrangement memory 7.

For example, the display screen 12 of the display unit 3 arranged so that the input surfaces of the input unit 8 overlap each other is
Display areas 12b to 12e, which are the predetermined areas set in association with the data processing by Further, it has a display area 12a surrounded by these display areas 12b to 12e. Such regions 12a-12
The display data is displayed in e.

The indicating device 9 used by the operator to indicate the input surface of the input unit 8 on the display screen 12 of the display unit 3 is
For example, the pressure detection unit 10 including a strain gauge
including. The pressure detector 10 detects the pressure applied to the input surface by the indicating device 9. The pointing device 9 includes, for example, the pointing device main body 13 and the cap 1 as shown in FIG.
4, 15, substrate 16, cable 17, support plates 18, 2
0, an electrode 19, a spring 21, and a strain gauge 22. The pointing device 9 has a pen shape, and the pointing device 9 and the input unit 8 constitute a so-called pointing device.

A substrate 16 provided with an electronic circuit, a part of a cable 17, support plates 18 and 20, electrodes 19, a spring 21 and a strain gauge 22 are arranged in a cylindrical indicator main body 13, and One end is cap 1
4, the other end is closed by the cap 15. A cable 17 is connected to the cap 14 side of the substrate 16 inserted and fixed in the insertion hole 18a of the support plate 18, and the cable 17 is led out from the insertion hole 14a of the cap 14 to the outside. Further, the tip of the electrode 19 fixed by being inserted into the insertion hole 20a of the support plate 20 is the cap 1
It is provided so as to project from the insertion hole 15a of the No. 5 and is biased by the spring 21 so that the projecting length L is changed by the pressing force of the operator. Substrate 16 and electrode 19
Are connected to the strain gauges 22 in the main body 13, respectively. When the operator presses the protruding electrode 19 portion against the input surface, the length L changes,
When the strain amount of the strain gauge 22 changes, the writing pressure is detected as electrical information by an electronic circuit or the like provided on the substrate 16. The detected writing pressure is given to the control unit 2 via the cable 17.

Further, referring to FIG. 1, a buzzer 11 which is a warning information generating means is connected to the indicating device 9, and a writing pressure larger than a predetermined threshold value is applied to the pressure detecting portion 10.
A buzzer sounds when it is detected by.

FIG. 4 is a flow chart showing the pressure detection procedure of the pressure detection unit 10. FIG. 5 is a graph showing the relationship between the writing pressure level and the resistance value of the strain gauge 22. When the input device 8 instructs the input surface of the input unit 8, the coordinate points of the input surface instructed by the input unit 8 are detected and given to the control unit 2 and the strain gauge 2 at step a1.
The resistance value of 2 changes, and the changed resistance value is converted into a voltage value by the circuit provided on the substrate 16. In step a2, the converted resistance value of the strain gauge 22 is converted into numerical data by, for example, an AD (analog / digital) converter also provided on the substrate 16. The numerical data is writing pressure, and is converted in the relationship as shown in FIG. 5, for example. The resistance value of the strain gauge may be proportionally converted, for example, other than the relationship shown in FIG.

In step a3, it is judged whether or not the obtained writing pressure level is higher than a predetermined writing pressure level, and if it is larger, it is judged as a dangerous pressure, and the process moves to step a6 and the buzzer 11 buzzer sounds. Is generated. If it is not large, it is determined that the pressure is not dangerous and the process moves to step a4 and the buzzer 11 does not generate a buzzer sound. For example, from the relationship shown in FIG. 5, it is possible to generate a buzzer sound by setting a range where the writing pressure level exceeds “11” as a warning range (dangerous pressure range). The above-described conversion into writing pressure is performed in the instructing device 9, and when the processes of steps a4 and a6 are completed, the process proceeds to step a5 and the conversion result of the AD converter, that is, the writing pressure is given to the control unit 2. . When the process of step a5 ends, the process returns to step a1. In this way, the writing pressure detected by the pressure detection unit 10 is constantly applied to the control unit 2.

The data processing apparatus 1 is characterized in that the scroll speed is changed according to the writing pressure detected by the pressure detecting section 10 and has a scroll means memory 23 and a weight counter 24 shown in FIG.
In the scroll means memory 23, a plurality of means such as an icon for designating scroll processing of the display data displayed on the display screen is stored in advance. Means such as icons scroll the display data in different ways. The means such as these icons may be selected or changed by the operator according to the type of display data. Further, the selection or the change may be automatically made.

A display area 1 as shown in FIG. 2, for example.
On the display screen 12 composed of 2a to 12e, the data stored in the main memory 5 is displayed on the display screen 12, and the operator can display the cursor at the position designated by the pointing device 9 in the range of the display area 12a. . Further, by scrolling the display areas 12b to 12e, the scroll processing of the display data is executed. For example, when a point in the area 12b is designated, the display data is scrolled downward. Similarly, when a point in the areas 12c to 12e is designated, scroll processing in the right direction, the upward direction, and the left direction is performed. Executed respectively.

FIG. 6 is a flowchart showing the procedure of the scroll process. In step b1, the instruction device 9 indicates a point in the display area 12b, for example, and the control unit 2 recognizes that the display data is scrolled downward and sets an initial value in the weight counter 24. When it is determined in step b2 that the point in the area 12b has been designated for a certain period of time, the process proceeds to step b3 and the initial value of the weight counter 24 is subtracted. Here, the subtraction speed is selected based on the writing pressure detected by being instructed by the instruction device 9, and is subtracted in accordance with the relationship between the writing pressure and the counter subtraction speed as shown in Table 1, for example.

[0025]

[Table 1]

At step b4, the weight counter 24
It is determined whether or not the subtracted value by is smaller than "0", and if so, the process proceeds to step b5, and if not, the process returns to step b2. At step b5, the control unit 2 instructs the display data conversion unit 6 to switch the coordinates of the display screen to new coordinates. At this time, the relationship between the writing pressure and the change in the display position shown in Table 1 is used to calculate the new coordinates, and the change amount of the display position of the display data is changed according to the detected writing pressure level. Alternatively, the new coordinates are calculated by different processing depending on the detected writing pressure level. For example, when the writing pressure level is "1", the subtraction speed "50" is subtracted in step b3, and when the initial value is smaller than "0", the display data corresponds to one dot,
New coordinates are set to scroll down.

At step b6, the display data converting section 6 reads out necessary data from the main memory 5, creates display data and stores it in the VRAM 4 of the display section 3. When the process of step b6 ends, the process returns to step b1.

By the above procedure, the display data is scrolled under the scroll condition determined from the detected writing pressure level based on the relationship shown in Table 1,
Display data can be displayed on the display screen 12. Therefore, by adjusting the writing pressure by the operator, high-speed scrolling or low-speed scrolling can be easily performed at the speed desired by the operator and without moving the pointing device 9.

FIG. 7 is a flowchart showing a procedure for creating another scroll processing condition. FIG. 8 is a plan view showing the display screen 25. Display area 12 shown in FIG.
“A” corresponds to the display area 25a of the display screen 25, and the display areas 12b to 12e that specify the scroll processing correspond to the display areas 25b and 25c of the display screen 25. Display screen 2
In FIG. 5, one display area for designating scroll processing is set in each of the horizontal direction and the vertical direction. Further, scroll direction designation regions 26a to 26d for designating the scroll direction are set in each region. Operator is area 2
Display data can be scrolled in the left-right and up-down directions by instructing 6a to 26d. The graphic data indicating the areas 26a to 26d is stored in the scroll means memory 23. Further, it is assumed that the main memory 5 stores the text data described in horizontal writing as shown in the figure.

At step c1, the control unit 2 confirms the characteristics peculiar to the data such as the type and size of the data stored in the main memory 5, and the minimum unit of the scroll processing is determined. In this case, since the displayed data is text data, the minimum scroll unit is set to one character. If the data is not text data but image data such as graphic data, the minimum scroll unit is set to 1 dot.

At step c2, the scroll movement method is determined. For example, when there is an edit symbol such as a predetermined term / chapter, the search moving method is adopted, and when there is no such edit symbol, the constant width moving method is adopted. At step c3, the scroll speed in the vertical direction is determined from the size of the text data, for example, the total number of lines. Step c
In 4, a relatively slow scroll condition is determined. In step c5, the scrollable distance and the total number of pages / chapters are obtained, and in step c6, a relatively high speed scroll condition is created. At step c7, the scroll condition in the middle portion between the low speed and the high speed is determined. In step c8, it is determined whether or not adjustment is necessary for the scroll conditions created in steps c4, c6, c7, and if so, the scroll conditions are changed. Therefore, the process returns to step c4. If it is unnecessary, the process proceeds to step c9, and it is determined whether or not the scroll conditions for the vertical and horizontal directions have been created. If it has not been created, the process returns to step c4 and the scroll conditions in the left-right direction are created in the steps c4 to c8.

Table 2 shows the scroll conditions created by the above procedure. In the case of text data written horizontally, the size of the display data in the horizontal direction is relatively small, and the size in the vertical direction is large in many cases. Therefore, as shown in Table 2, even when a relatively high writing pressure is detected, scrolling in the left-right direction is set to be performed at a slow speed. In this way, it is possible to set different scroll conditions in the vertical direction and the horizontal direction. Therefore, the scroll processing can be performed under conditions that are more convenient for the operator, and operability is improved.

The search movement method determined in step c2 mentioned above corresponds to, for example, a change in the display position when the writing pressure level in scrolling up and down in Table 2 is "9" to "12". To do. Also, with the constant width movement method,
The change in the display position when the writing pressure level is "0" to "8" corresponds to this. In the case of the constant width movement, the scroll movement width is set to the same width every time, and if the writing pressure level is the same, the scroll is performed in the constant width. Also, in case of search move,
For example, in the case of "move to the next page", "next page break symbol" is searched every time scrolling is performed, and then scrolling is performed to display this part. That is, in this case, the scroll movement width changes depending on the data.

The adjustment for the scroll condition created in step c8 described above is performed when the data to be displayed is biased. For example, if the length of the display data divided by the edit symbols of the predetermined “chapter” is about several lines and is relatively small, no matter how the scroll condition of the middle part is set in step c7. , Inconsistency may occur as a whole operation. Specifically, in scrolling up and down in Table 2, the scroll speed may be slower at the writing pressure level "9" than at the writing pressure level "8". When such a contradiction is remarkable, it is determined in step c8 that adjustment is necessary, and again in steps c4 to c7, scroll conditions are created so that the contradiction is reduced.

[0035]

[Table 2]

In this embodiment, the pen type device is described as the pointing device 9, but the pointing device 9 may be realized by a mouse, a trackball or the like. In this case, a cursor is displayed on the display screen designated by the mouse or trackball. Further, although the example in which the strain gauge 22 is used as the pressure detection unit 10 has been described, it may be configured by, for example, an input switch that is turned on in stages, a slide type volume switch, or the like.
Further, the designated area for scroll processing on the display screen is not limited to that described in the present embodiment, and may be set to a different shape. Further, the data processing other than the scroll processing may be executed by changing the processing condition based on the detected writing pressure level.

[0037]

As described above, according to the present invention, the data processing condition is changed and the data is processed based on the pressure level applied by the indicating means. Therefore, the operator can change the data processing condition without moving the instruction means, and can change the condition and process the data by a simple operation. Further, the scroll speed of the display data can be changed based on the pressure level.

Further, the scroll speed can be changed in consideration of characteristics peculiar to the display data such as the size of the display data. For example, in the case of display data displayed in vertical writing, the scroll amount in the vertical direction can be reduced, and in the case of display data displayed in horizontal writing, the scroll amount in the horizontal direction can be reduced. As a result, the scrolling process can be realized under a condition more convenient for the operator, the process of searching the displayed data and the like can be efficiently performed, and the operability is improved.

Further, since the warning information is generated when the applied pressure level becomes larger than the predetermined threshold value, it is possible to inform the operator that the high pressure is applied, and the data is erroneously erroneously read. It is possible to prevent the processing device from being damaged.
