BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a coordinate input and display method and apparatus for inputting position coordinates on a display screen of a display device provided in a computer device, etc., and for displaying the input position.

0002

2. Description of the Related Art Computer devices and the like are equipped with display devices for inputting and outputting data. A cursor or a display symbol called an icon (hereinafter collectively referred to as a cursor) is used as a mark indicating which position on the display screen of this display device is a processing target position. Various coordinate input means are used to move this cursor to any coordinate position on the display screen. Among these, devices commonly referred to as mice, joysticks, trackballs, etc. are easy to operate in practice because the cursor can be moved in any direction on the display screen by moving the operating section. .

A mouse is generally a device with three bearings on the bottom, and is operated by rolling it on a desk to obtain coordinate values from the rotation angle of the bearings. A joystick is generally a device with an operating rod that is gripped and tilted to any desired position, such as forward, backward, left, or right, to obtain coordinate values. Furthermore, a trackball includes a ball that can be rotated in any direction, and is used to rotate this ball with the palm or fingertips and obtain coordinate values from the rotation angle of the ball. When these devices are moved, they simultaneously output an X-axis movement amount signal and a Y-axis movement amount signal that determine the direction and amount of movement of the cursor. The computer main body inputs the movement amount signals of these respective axes and controls the movement of the cursor on the display screen by an amount commensurate with the movement amount signals.

Coordinate input devices such as the above-mentioned mouse are often used in the field of computer equipment because they are easy to handle.

However, since this type of device requires continuous operations such as rolling it around on a desk, there is a problem in operability when inputting delicate coordinate positions. For this reason, in recent years, pen-based coordinate input means have come into use. Generally, a pen-type coordinate input device includes a tablet configured to correspond to a display screen of a display device, and an input pen that specifies coordinates by bringing its tip into contact with the surface of the tablet. By bringing the tip of the input pen into contact with an arbitrary target position on the surface of the tablet, the cursor is controlled to move to an arbitrary target position on the display screen corresponding to this position. Note that the cursor on the display screen is controlled to remain displayed at the position from which the pen was released until the pen is removed from the surface of the tablet and comes into contact with the surface of the tablet again. Of course, if the pen is moved continuously on the tablet while in contact, the cursor is controlled to follow this movement and move continuously. Therefore, unlike the above-mentioned mouse, etc., when moving the cursor to other coordinates, this type of device does not need to touch the desk or the like and move continuously, and can specify distant coordinate positions discontinuously. Therefore, the operability is good.

[0006] References to this type of technology include JP-A-61-131025 and JP-A-2-110621.

[0007]

[Problems to be Solved by the Invention] Although the pen-based coordinate input device described above has the above-mentioned advantages, it is difficult to input new coordinates by moving the pen off the surface of the tablet and bringing it into contact with another position. When inputting a cursor, the operator often loses track of the cursor position on the display screen, which poses a problem in terms of operational efficiency. This is especially serious when specifying a coordinate position that is further away from the previous position.

The present invention has been made in view of the above points, and its object is to provide a coordinate input display method and apparatus that can improve operability.

Another object of the present invention is to provide a coordinate input display method and apparatus that allows a newly input coordinate position to be easily determined.

Still another object of the present invention is to provide a coordinate input/display method and apparatus that can easily determine the designated coordinate position on the display screen.

[0011]

[Means for Solving the Problems] In order to achieve the above object, the present invention is characterized by detecting discontinuous coordinate designation by a coordinate input means, and by detecting discontinuous coordinate designation by a coordinate input means, and by detecting discontinuous coordinate designation by a coordinate input means. The purpose is to highlight the cursor position. Various methods can be used for this highlighting, such as changing the display shape of the cursor, changing the display brightness, changing the display color, or highlighting the cursor by a combination of these. When highlighting, the new coordinates can be highlighted for a predetermined period of time after they are specified, and then return to the normal display state, or the new coordinates can be specified and the coordinates can be changed by moving a pen, etc. It may remain highlighted until it is displayed. This highlighted display time is not particularly limited, and various measures can be taken as necessary. When detecting discontinuous coordinate designation, the distance between the previous coordinate designation position and the current coordinate designation position may be calculated, and the detection may be performed based on the fact that the distance is at least a predetermined distance; It may also be possible to detect that the input pen has left the surface of the tablet, and then to detect that the input pen has come into contact with the surface of the tablet.

According to another preferred aspect, discontinuous coordinate designation by the coordinate designation means is detected, and the relationship between the previous cursor position and the current cursor position is displayed on the display screen based on the detection. According to a preferred embodiment, this association consists in displaying the previous cursor position and the current cursor position on the display screen, connected by a trajectory, for example a straight line. Furthermore, the cursor may be controlled so that it moves from the previous position to the current position. When displaying a straight line, the type of the line does not matter. It may be a solid line, a broken line, or another type of line. In short, it is sufficient as long as the operator can clearly identify it. Note that in this case as well, this line may be highlighted. In addition, when displaying this line or displaying it with highlighting, it may be highlighted only for a predetermined period of time after the new coordinates are displayed, and then this line may be erased. The line may be displayed until coordinates are specified and the coordinates are changed by movement of an input pen or the like.

Further, according to the present invention, discontinuous coordinate detection means detects discontinuous coordinate designation by the coordinate designation means;
A coordinate input display device is provided which includes highlighting means for highlighting a cursor position on a display screen corresponding to the coordinate position in response to detection of discontinuous coordinate designation by the detection means.

Furthermore, according to the present invention, discontinuous coordinate detection means detects discontinuous coordinate designation by the coordinate designation means;
A coordinate input display device is provided which includes highlighting means for displaying the relationship between the previous cursor position and the current cursor position on a display screen in response to the detection of discontinuous coordinate designations by the detection means.

[0015]

[Operation] If you do the above, for example, if you move the input pen off the surface of the tablet and input a new coordinate position by touching it to another position, it will be detected that the input pen is discontinuous. . Then, as a result of this detection, the cursor that has been controlled to move to the designated coordinate position on the display screen is highlighted at that position, so the operator can very easily confirm the cursor at the designated coordinate position. This allows the operator to improve the operability of the cursor operation.

Furthermore, according to the present invention, when discontinuous coordinate positions are input by the coordinate input means, the relationship between the previous cursor position and the current cursor position is displayed on the display screen.
For example, since the previous cursor position and the current cursor position are displayed connected by a straight line on the display screen, the operator can very easily confirm the cursor at the designated coordinate position.

[0017]

[Embodiment] An embodiment of the present invention shown in the drawings will be described below.

FIG. 2 is a block diagram showing the overall hardware configuration of an embodiment of the present invention. This device is a relatively small computer device, generally of a type called a personal computer device or a business computer device. It is constructed by connecting a coordinate input device to a computer device COM. Reference numeral 2a denotes this coordinate input device, and in this embodiment, as described later, it includes a tablet and an input pen for inputting coordinates on a coordinate indication surface of the tablet. 2b, 2c, 2d, and 2e are a central processing unit, a memory, a display device, and a keyboard serving as an input device, which constitute the computer device COM.

As shown in FIG. 3, the coordinate input device 2a includes a tablet TB and an input pen 3a for inputting coordinates on the coordinate indication surface 3b of the tablet TB. This type of tablet TB generally requires status information indicating whether or not the tip of the input pen 3a is in contact with the coordinate indicating surface 3b, and X coordinate information and Y coordinate information indicating the contact position. The information is sequentially output according to the information, and this information is input to the computer device COM. Generally, the status information includes pen down information indicating that the input pen 3a is in contact with the coordinate indicating surface 3b of the tablet TB;
It also includes pen-up information indicating that the input pen 3a is away from the coordinate indicating surface 3b of the tablet TB.

The coordinate indicating surface 3b of the tablet TB corresponds to the display screen of the display device 2d, and when a target position on the coordinate indicating surface 3b is sequentially touched and indicated with the input pen 3a, data regarding each target position is displayed as X, Y coordinate value information is sequentially output. The computer device COM sequentially inputs this information and sequentially controls the movement of the cursor on the display screen of the display device 2d to the corresponding coordinate position based on this information. The cursor movement control means for achieving this type of function is stored in the memory 2c of the computer device COM in the form of a program, and the central processing unit 2b sequentially reads this program and executes it to achieve a predetermined function. be done.

FIG. 1 is an explanatory diagram showing an example of the operation of this embodiment, where 2d is a display device and SC is its display screen. CS is a cursor displayed on this display screen SC. TB is a tablet, 3b is a coordinate indication surface, and 3a is an input pen. According to this embodiment, the input pen 3a indicates point a on the coordinate indicating surface 3b of the tablet TB, and the cursor CS points to a' on the display screen SC.
When the input pen 3a is lifted from the coordinate indication surface 3b of the tablet TB from the position at the point, and the next input instruction is made for point b, the cursor CS at point a' disappears and the cursor CS is displayed at point b'. Almost simultaneously, a straight arrow AR is displayed on the display screen SC from point a' to point b', which corresponds to point b on the coordinate indication surface 3b of the tablet TB. After a while, this straight line disappears. This straight arrow AR allows the operator to easily and clearly confirm to which position the cursor CS will move from the previous position. Generally, an operator performs an input operation while paying attention to the position of the cursor CS. Therefore, the previous position of the cursor CS is confirmed. Therefore, it is extremely effective to use the previous position as a reference and display the movement trajectory of the cursor CS from there on the display screen SC.

FIG. 4 is a flowchart showing the overall processing procedure of the computer device COM in this embodiment.
The processing means shown in this flowchart is stored in the memory 2c in the form of a program. By executing this processing means, first, in step 4a, each part of the computer device COM is initialized, and the computer device COM is set to be operable. In the subsequent step 4b, commands or data input from an input device such as the keyboard 2e are input. In step 4c, it is determined whether the command input in step 4b is a command for instructing termination of computer processing, and if it is a command for instructing termination, computer processing is terminated. If the command does not mean termination, the process moves to the subsequent step 4d. This step 4d is performed by the pen coordinate input means PE, which is the main part of this embodiment.
This is the execution of NIN, and by executing this means, the processing operation shown in FIG. 1 is executed as described later. In step 4e, the coordinate input in step 4d is received, the corresponding processing is executed, and the processing is moved to step 4b. From then on,
The processes of steps 4b, 4c, 4d, and 4e are repeatedly executed until an end command is input.

FIG. 5 is a flowchart showing the pen coordinate input means PENIN which constitutes the main part of this embodiment. When this means PENIN is activated, it first performs step 5.
In step a, the input coordinate reading means IPREAD is activated. The input coordinate input means IPREAD inputs designated coordinate information input from the coordinate input means 2a, as will be described in detail later. Subsequently, in step 5b, the coordinate updating means PMEMT is activated and executed. This coordinate updating means PMEM
As will be described in detail later, T updates the storage contents of various coordinate temporary storage units based on the coordinate information taken in step 5a. Then, in step 5c, the cursor CS is moved and displayed on the coordinates on the display screen SC that have been inputted based on the coordinate information imported by the input coordinates importing means IPREAD. Subsequently, in step 5d, the highlighting means LP
Start up and execute the DSP. This highlighting means LPDSP displays the coordinate position of the inputted cursor CS on the screen SC.
In order to display the above more clearly, a straight arrow AR is displayed for a certain period of time between the previous coordinate position and the current coordinate position, and the trajectory of the cursor CS is displayed.

FIG. 6 is a memory map showing the configuration of various coordinate temporary storage units necessary to execute the processing shown in FIG. 5. This kind of coordinate temporary storage section is allocated and set in advance in the memory 2c of the computer device COM at the time of its initial setting. TCM is a current coordinate storage unit that stores coordinates newly input this time by the coordinate input device 2a. L
CM is a previous coordinate storage unit that stores the coordinates immediately before the coordinates input this time. DCM is a current coordinate storage unit that stores the coordinates where the cursor CS is currently displayed. S.C.
M is a starting point coordinate storage section that stores the starting point coordinates of the straight arrow AR when the straight arrow AR indicating the locus of the cursor CS is displayed on the display screen SC. ECM is cursor C
This is an end point coordinate storage section that stores the end point coordinates of the straight arrow AR when displaying the straight arrow AR indicating the locus of S on the display screen SC. Note that each of these storage units TCM, LC
Although the M, DCM, SCM, and ECM are omitted, they are each equipped with an X coordinate storage section and a Y coordinate storage section, and one coordinate can be stored in the X coordinate storage section and the Y coordinate storage section. Remember.

Hereinafter, each means of each step shown in FIG. 5 will be explained with reference to FIG. 6.

FIG. 7 is a flowchart showing the input coordinate input means IPREAD executed in step 5a in FIG.
The coordinate information input by the input pen 3a is read from the input pen 3a. In the subsequent step 7b, it is determined whether the coordinate information has been read, that is, whether the coordinate information has been input. If there is no coordinate information input here, the process goes to step 7b.
and waits for input of coordinate information from the coordinate input means 2a. If coordinate information is input from the coordinate input means 2a in step 7b, the inputted coordinate information is stored in the current coordinate storage unit TCM in the subsequent step 7c, and the processing of this input coordinate acquisition means IPREAD is ended. That is, by the action of this means IPREAD, by indicating a desired position on the coordinate indicating surface 3b of the tablet TB with the input pen 3a, this position coordinate is stored in the current coordinate storage unit TCM.

FIG. 8 is a flowchart showing the coordinate updating means PMENT executed in step 5b in FIG. The contents of the current coordinate memory DCM that stores the coordinate information are read out, and this coordinate information is stored in the previous coordinate memory LCM.
Store in memory. Subsequently, in step 8b, step 8
The contents of the previous coordinate storage unit LCM that was updated in step a are read out, and this coordinate information is stored in the end point coordinate storage unit SCM. Next, in step 8c, the input coordinate importing means IP
Current coordinate storage unit T read and stored by READ
The contents of the CM are read and the coordinate information is stored in the end point coordinate storage section ECM. In step 8d, step 8
The contents of the end point coordinate storage unit ECM updated in step c are read out, and this coordinate information is stored in the current coordinate storage unit DCM. Each temporary storage section is set for subsequent processing by the processing means coordinate updating means PMENT.

FIG. 9 is a flowchart showing the cursor display updating means CDISP executed in step 5c in FIG. Delete cursor CS. Continued step 9b
Then, the cursor CS is displayed at the position on the display screen SC indicated by the current coordinate storage unit TCM, and the process is ended. This cursor display updating means CDISP erases the cursor CS that was displayed until the previous time, and a new cursor CS is displayed at the coordinate position specified this time.

FIG. 10 is a flowchart showing the highlighting means LPDSP executed in step 5d in FIG. and the contents stored in the end point coordinate storage unit ECM to determine whether the distance between the start point coordinate and the end point coordinate is a predetermined distance or more. Steps 8b and 8c in FIG.
As is clear from the above, the starting point coordinates are the previous coordinates, and the ending point coordinates are the current coordinates. Therefore, this step 1
0a is for determining how far the coordinate position specified by the input pen 3a this time is from the previous position. As a result of the determination in step 10a, if this distance is not greater than the predetermined distance, the subsequent processing is skipped and the processing of the highlighting means LPDSP is ended. If this distance is a predetermined distance or more, the process moves to step 10b. In step 10b, as shown in FIG. 1, a straight arrow AR is displayed on the display screen SC between the starting point coordinates and the ending point coordinates, that is, between the previous coordinate point a' and the current coordinate point b'. Subsequently, in step 10c, a waiting process for a certain period of time is executed. This is sufficient time for the operator to confirm the coordinates on the display screen SC specified this time, and 1 second, or around 1 second, is sufficient. When this set time has elapsed, the display screen S is displayed in step 10d.
This straight arrow AR is deleted from C and the process is completed.

This highlighting means LPDSP performs step 1
0a, and it is determined whether or not to display the straight arrow AR on the display screen SC depending on whether the distance between the starting point coordinate and the ending point coordinate is a predetermined distance or more. That is, if the distance is a certain distance or more, the straight arrow AR is displayed, otherwise it is not displayed. Therefore, if the coordinate indicated position by the input pen 3a is next to or near the previous coordinate, the straight arrow AR is not displayed. Therefore, when the coordinate indicating surface 3a of the tablet TB is continuously traced with the input pen 3a, the straight arrow AR is not displayed. This relieves the operator from checking redundant information.

As described above, if the embodiment is followed, the input pen 3
a indicates point a on the coordinate indicating surface 3b of the tablet TB, and from the state where the cursor CS is located at point a' on the display screen SC, lift the input pen 3a from the coordinate indicating surface 3b of the tablet TB. Next, when you input the point b, the coordinates of the point b are imported in step 7a of FIG.
This coordinate is stored in step 7c. Various coordinates are stored in each step of FIG. 8, and then, in step 9a of FIG. 9, the cursor CS at point a' is erased, and in the next step 9b, the cursor CS is displayed at point b'. Subsequently, in step 10a, the distance between points a' and b' is calculated, and since they are separated by a certain distance, a straight arrow AR is displayed from point a' to point b'. After a while, this straight line disappears, and the cursor CS at point b' remains on the display screen SC. This allows the operator to easily and clearly confirm to which position the cursor CS has moved from the previous position. Generally, an operator performs an input operation while paying attention to the position of the cursor CS. Therefore, the previous position of the cursor CS is confirmed. Therefore, using the previous position as a reference, the movement trajectory of the cursor CS is displayed on the display screen SC.
Displaying the information above is extremely effective.

[0032] In the above embodiment, the case where a straight arrow AR is displayed from the previous coordinate to the current coordinate has been explained, but this may simply be a simple straight line, and there are no restrictions on the type of line. In short, it is sufficient as long as it can be easily confirmed by the operator. In addition, in the example, the straight line A
Although R is displayed for a certain period of time, there is no time limit for this, and this straight line AR is displayed until the operator specifies the coordinates this time and then specifies the next coordinates. Good too. In this way, for example, in FIG. 1, after the operator specifies point b and confirms point b' on the display screen SC, the operator can input from this position without removing the input pen 3a from the coordinate indication surface 3b. When the pen 3a is moved, the straight line AR is erased in response to this movement. In this way, until the operator confirms the cursor CS, the straight line AR
can be displayed, providing even better operability to the operator.

FIG. 11 shows the highlighting means LP shown in FIG.
This shows another embodiment of the DSP, and the difference from FIG. 10 is step 10b' and step 10c'. That is, in this embodiment, instead of displaying the straight line AR to let the operator confirm the current coordinates, point b' in FIG. 1, the operator can confirm the current coordinates by highlighting the cursor CS at the current coordinates. It is an attempt to do so. Therefore, if the start point coordinates and the end point coordinates are separated by a certain distance or more in step 10a, the cursor CS located at the end point coordinates in step 10b', that is, b in FIG.
A highlighting attribute is given to the cursor CS at point ', and this cursor CS is highlighted. Various methods can be used for this highlighted display, such as changing the display shape of the cursor, changing the display brightness, changing the display color, or displaying the cursor by a combination of these. And step 10c
After displaying the cursor CS for a certain period of time in this state, the highlighting attribute of the cursor CS is canceled in step 10d',
This is to return the display of the cursor CS to its normal state. Also, in this embodiment, as described above, the highlighted display time of the cursor CS is not set to a fixed time, but the highlighted display is continued until the operator specifies the current coordinates and then the next coordinates. may also be executed.

Furthermore, in both FIGS. 10 and 11, the case where the starting point coordinates and the ending point coordinates are separated by a certain distance or more is the subject of highlighting processing, but this is because the operator specifies discontinuous coordinates. was attempted to be determined based on the distance between the previous coordinate and the current coordinate. However, this may be determined as follows without incorporating the concept of distance. That is, as described above, the coordinate input means 2a having the input pen 3a and the tablet TB transmits pen down information to the computer device indicating that the input pen 3a is in contact with the coordinate indicating surface 3b of the tablet TB. ,
Status information including pen-up information indicating that the input pen 3a is away from the coordinate indicating surface 3b of the tablet TB is input. Therefore, we monitor the point at which the status information changes from pen-up information to pen-down information,
Discontinuous coordinate designation by the operator may be detected by detecting the time point of this change. Of course, the element of distance may be combined with this detection. For example, FIG.
In step 10a of FIG. 11, steps 10b, 10c, and 10d may be executed when there is a change in the pen-down information and the starting point coordinates and the ending point coordinates are separated by a certain distance or more.

[0035]

Effects of the Invention As is clear from the above description, according to the present invention, it is extremely easy to move the cursor at the input coordinate position, despite using a coordinate input means that can specify distant coordinates discontinuously. Accordingly, it is possible to obtain a coordinate input display method and apparatus that can confirm the following, and as a result, improve the operability of coordinate input.
