BACKGROUND OF THE INVENTION
The present invention relates to a coordinate input device that moves while pressing a tablet sheet and controls the movement of a cursor displayed on a display of a personal computer. More specifically, the present invention relates to a coordinate input device that is compatible with a mouse and has the same output data as a mouse. The present invention relates to a coordinate input device that outputs data to a personal computer in a format.
[0002]
[Prior art]
In recent years, with the development of GUI (Graphical User Interface) environment, a mouse is widely used as a pointing device of a personal computer (hereinafter referred to as a personal computer) 1.
[0003]
That is, the mouse is moved on the operation pad, the relative movement amount is output to the personal computer 1 as mouse relative movement data, and the movement of the cursor displayed on the display of the personal computer 1 is controlled.
[0004]
However, since the mouse needs to be moved on the operation pad in this way, it is difficult to secure an operation space at the destination in the portable type personal computer 1 such as the notebook type personal computer 1 and is carried with the personal computer 1. The size and shape are not suitable for storage.
[0005]
For this reason, as shown in FIG. 5, a thin plate-like coordinate input device 5 having a tablet sheet 6 as an input surface is used as a pointing device.
[0006]
The coordinate input device 5 detects the pressing position of the tablet sheet 6 by the same means as the position detection means used in the tablet, such as a known capacitance method or resistance contact method.
[0007]
The pressing position data of the pressing position is included in the device output data and is output to the personal computer 1.
[0008]
The device output data has the same data format as the mouse output data so that the coordinate input device 5 is compatible with the mouse.
[0009]
FIG. 6A shows a so-called serial mouse data format. Of the mouse output data consisting of 3 bytes, mouse relative position data representing the amount of movement in the X direction is represented by bit positions represented by X0 to X7. , Y0 to Y7 include mouse relative position data representing the amount of movement in the Y direction.
[0010]
The device output data includes the X and Y pressing position data of the coordinate input device 5 instead of the mouse relative position data.
[0011]
This device output data is input to the device driver 4 via the I / O port 8 for mouse connection as shown in FIG. 5, and the device driver 4 regards the pressing position data of the tablet sheet 6 as mouse relative position data. Form position information for cursor control.
[0012]
Therefore, by moving the pressing of the tablet sheet 6, the cursor can be moved as if operating the mouse.
[0013]
On the other hand, the mouse has a function of operating a mouse switch provided in the mouse to input a mouse-specific operation such as click, double-click, and drag.
[0014]
As shown in FIG. 5, the coordinate input device 5 is also provided with a pair of left and right tablet switches corresponding to this mouse switch. As described above, the coordinate input device 5 is thin and small, and is a tablet sheet with one hand. It was difficult to operate 6 and the tablet switch.
[0015]
In particular, when an operation corresponding to mouse dragging is input, it is necessary to press and move the tablet sheet 6 while pressing the tablet switch, and this operation cannot be performed with one hand.
[0016]
The conventional coordinate input device 5 has a problem with this operability, and has become an obstacle to the spread of the coordinate input device 5.
[0017]
Therefore, a coordinate input device 5 has been developed that represents mouse switch operations such as clicking and double-clicking, based on the number of times the tablet sheet 6 is tapped (hereinafter referred to as tapping) and its interval.
[0018]
FIGS. 7 and 8 are waveform diagrams for explaining the operation of the coordinate input device 5. FIG. 7 shows each operation of the mouse and mouse output data for comparison of the operations of the coordinate input device 5. This shows the output timing.
[0019]
The operation of the mouse switch is determined by a change in mouse switch status data indicating whether the switch is depressed (ON) or released (OFF). Thus, every time there is a change in this data, mouse output data is output.
[0020]
The mouse switch status data indicates, for example, that “1” is ON and “0” is OFF. As shown in FIG. 6A, the right side of bit 4 (R) of the first byte of mouse output data The switch status data includes the left switch status data in bit 5 (L). Since operations such as click and double click are normally assigned to the left switch of the mouse, bit 4 (R) does not change with “0”, and only bit 5 (L) is “1” and “0”. Vary between.
[0021]
For example, mouse output data (A) and (B) in FIG. 7 when the mouse left switch is single-clicked are respectively shown in FIGS. 6B and 6C.
[0022]
Further, since the mouse relative movement data is also output from the mouse when the mouse is moved on the operation pad, the mouse output data is either mouse switch status data or mouse relative movement data as shown in FIG. Alternatively, it is output every time there is a change in both.
[0023]
The conventional coordinate input device 5 defines tapping operations individually corresponding to the respective operation modes of the mouse as shown in Table 1, and the table 1 shows whether or not there is a movement while pressing the tablet sheet 6 and pressing. It is determined whether or not the tapping operation is defined, and when any mode is satisfied, the same device output data as the mouse output data is output as shown in FIG. 8 in accordance with the operation mode.
[0024]
Table 1
[0025]
For example, when tapping is performed once, it is regarded as single click from Table 1 (a), and when tapping is performed twice, it is regarded as double click from Table 1 (b).
[0026]
In the same table, the pressing time t of the tablet sheet 6 _a When t is between 25 msec and 150 msec, it is determined that a tapping operation has been performed. This is to exclude the case where the tablet sheet 6 is pressed by an operation other than tapping.
[0027]
After one tapping, t _b If the tablet sheet 6 is not pressed during this period, it is not tapping for another mode, so it is determined as a single click (Table 1 (a)).
[0028]
In addition, after one tapping t _b If the tablet sheet 6 is further pressed within the period and this pressing is a tapping operation, double-clicking (Table 1 (b)) and the pressing is t _c If the relative movement position data changes during pressing for more than a certain time, it is determined as a drag (Table 1 (c)). The drag mode and the normal relative position data input mode differ depending on whether or not a tapping operation has been performed immediately before.
[0029]
Since the device output data corresponding to each operation mode of the mouse is output after a predetermined determination period after performing the tapping operation in this way, the output timing is clear by comparing FIG. 7 and FIG. Thus, it will be delayed from the output timing of the mouse.
[0030]
However, in terms of the unit of each operation mode of the mouse, for example, the device output data when it is determined to be clicked is as shown in FIG. 8 (b) in FIG. As in (c) of FIG. 6, the mouse output data is output at the same output interval and the same data as when the left switch of the mouse is clicked.
[0031]
[Problems to be solved by the invention]
Therefore, the conventional coordinate input device 5 can represent a mouse-specific mode by tapping the tablet sheet 6 while maintaining compatibility with the mouse. Since one of the modes needs to be determined by comparison, it is necessary to provide a determination unit including a memory for storing determination conditions, a clock, a timer, a comparator, and the like in the coordinate input device 5, which complicates the circuit. In addition, there is a problem that the coordinate input device 5 is increased in size.
[0032]
The determination conditions in Table 1 are stored in advance in a memory such as a ROM of the coordinate input device 5 at the time of shipment. Therefore, the conditions cannot be easily changed in accordance with the use state. Alternatively, it is difficult for the user to change the setting conditions inside the coordinate input device, and to require bidirectional communication with the personal computer 1.
[0033]
For example, the pressing time t of the tablet sheet 6 _a Is determined to be tapping when the time is between 25 msec and 150 msec, but for a user who performs tapping operation by pressing the tablet sheet 6 for 200 msec, the pressing time t in Table 1 (a) _a Need to be changed.
[0034]
It is also necessary to change the conditions when defining a new mouse mode in Table 1 or when changing two tappings to single click, three tappings to double click, etc. according to user's preference. There is.
[0035]
However, these condition changes require an input circuit for disassembling and replacing the memory or inputting a new condition, and a change circuit for changing the condition.
[0036]
In addition, mouse-specific operation modes such as click and double-click are performed by changing the mouse left switch status data of the device output data, assuming that the left switch of the mouse is operated. In other words, the device output data of (c) and (d) in FIG. 8 change the mouse left switch status data of bit 5 in the first byte as shown in FIGS. The change state is output as if the left mouse switch was operated.
[0037]
On the other hand, depending on an operating system (hereinafter referred to as OS) 10 activated in the personal computer 1, a function that can assign a mouse-specific function to a mouse right switch is provided for a left-handed user. In this case, the device driver 4 of the personal computer 1 monitors the change of the mouse right switch status data in the bit 4 of the first byte shown in FIG. 6A from the input device output data, and clicks, double-clicks, etc. judge.
[0038]
Accordingly, there has been a problem that the personal computer 1 whose mouse switch assignment has been changed by the OS 10 cannot transmit a mouse-specific mode from the coordinate input device 5.
[0039]
The present invention has been made in consideration of such circumstances, and it is not necessary to provide the coordinate input device 5 with a determination means for determining the operation mode of the mouse, and the tablet sheet 6 is tapped to perform operations specific to the mouse. A coordinate input device 5 input system that can output a mode and can easily change a determination condition for determining an operation mode of a mouse is provided.
[0040]
In addition, there is provided a coordinate input device 5 that can output a mouse-specific operation mode while maintaining compatibility with a mouse without providing a determination means for determining the operation mode of the mouse.
[0041]

[0076]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0077]
1 to 6 show an embodiment of the present invention. A coordinate input device 5 according to the present embodiment is compared with the device output data output to the conventional coordinate input device 5 just before the relative movement amount. Is provided with dummy data forming means for forming dummy data composed of pressing position data in which 0 is set, and when the tablet sheet 6 is pressed, the dummy data formed by the dummy data forming means is sent to the personal computer 1 as device output data. Output.
[0078]
Also in this coordinate input device 5, as in the prior art, the pressing position of the tablet sheet 6 is detected from, for example, the potential at the pressing position, and the position detection means for generating the pressing position data and the operating state of the left and right tablet switches are monitored. In addition, switch operation detection means for generating tablet switch status data representing the operation state of each switch is provided.
[0079]
The press position data is the 8-bit data representing the relative movement amount in the X and Y directions. The tablet switch status data is “1” when the switch is pressed down, and the press release is released. In this state, the left and right 1-bit data represented by “0”.
[0080]
These pressing position data and tablet switch status data are periodically monitored by a microcomputer provided in the coordinate input device 5, and when either or both of the data are changed, a device output including the data is output. The data is output to the mouse I / O port 8 of the personal computer 1 in accordance with the data format of FIG.
[0081]
For example, as shown in FIG. 1, the output timing (i) of the device output data output from the coordinate input device 5 is changed every time the status data of the tablet switch changes, and the pressing position of the tablet sheet 6 is changed. Output whenever data changes.
[0082]
The device output data (e) when the tablet left switch is pressed down and the device output data (f) when the tablet left switch is released down are respectively 1 as shown in FIGS. The fifth bit of the byte changes between “1” and “0”. At this time, the bit positions representing the pressed position data of the device output data are all “0” because the relative movement amount does not change. The most significant bit (MSB) of each byte is “1” or “0” indicating the header of each byte. In the same data format as that of the mouse according to the present embodiment, a 1-bit start bit and a 2-bit end bit are added for each byte. Therefore, one frame of device output data is composed of 30 bits. ing.
[0083]
The device output data (g) when the tablet right switch is pressed down and the device output data (h) when the tablet right switch is released are 1 respectively as shown in FIGS. 6 (d) and 6 (c). The fourth bit of the byte changes between “1” and “0”.
[0084]
Further, when only the pressing position data is changed without pressing the tablet switch, relative movement in the X direction and the Y direction is moved to the bit positions indicated by X0 to X7 and Y0 to Y7 in the device output data of FIG. Amount included.
[0085]
Further, the coordinate input device 5 is provided with a pen-on detecting means for periodically detecting the pressing (pen-on) and the releasing of the pressing (pen-off) of the tablet sheet 6, and automatically when the pressing of the tablet sheet 6 is not detected for a certain time. The coordinate input device 5 is provided with a function for setting it to a sleep mode that is a low power consumption mode.
[0086]
While the tablet sheet 6 is not pressed (pen-off), the pressed position data does not change, and therefore device output data is not output unless the tablet switch is operated.
[0087]
For example, as shown in FIG. 3 (a), the pressing of the tablet sheet 6 is released at the position B1, and the pressing movement is again performed from the position B2 to C in FIG. There may be a relative movement to C ′. In such a case, unless the tablet switch is operated from B1 to B2, the tablet switch status data and the pressed position data do not change until the relative movement from B2 is detected. Accordingly, the relative movement operation from A ′ to C ′ can be continued, and the cursor on the display is continuously displayed as shown in FIG.
[0088]
Note that if the tablet switch is operated during pen-off from B1 to B2, the tablet switch status data changes, so that device output data is output.
[0089]
In any case, since the tablet switch status data and the pressing position data immediately after detecting the pressing of the tablet sheet 6 are the same as the data related to the last output device output data, in this embodiment, The tablet switch status data and the pressing position data form dummy data, and when the pressing of the tablet sheet 6 is detected, the dummy data is output as device output data.
[0090]
That is, as shown in FIGS. 1 and 2, each time the tablet sheet 6 is pressed, dummy data indicated by hatching in the figure is output as device output data.
[0091]
For example, in the relative movement operation of FIG. 1, since the tablet sheet 6 is pressed, dummy data is output, but this dummy data (re) is a state in which the tablet switch immediately after pressing is in the state of releasing the press, Since there is no relative movement, as shown in FIG. 6C, all the data except the header are “0”.
[0092]
The detailed configuration of the position detection unit, the switch operation detection unit, and the pen-on detection unit is the same as that used in conventional tablets and digitizers, and thus description thereof is omitted.
[0093]
As described above, device output data input from the I / O port 8 of the personal computer 1 includes device output data (hereinafter simply referred to as “change data”) and dummy data output when the constituent data changes. However, since the dummy data is the same data as the device data output from the coordinate input device 5 immediately before, it can be determined as the former change data.
[0094]
The device driver 4 of the personal computer 1 discriminates the dummy data from the device output data input in the same data format as the mouse. FIG. 4 shows a procedure for discriminating dummy data from the input device output data and performing data processing of the dummy data.
[0095]
The device driver 4 is also a driver that processes mouse output data, so mouse output data may be input, but the mouse output data is also determined as dummy data according to the flowchart of the figure. Is called.
[0096]
However, since mouse output data composed of the same data is not continuously output as mouse output data, the procedure from step S1 to step S4 is handled in the same way as device output data including change information. For convenience, it will be described in the device output data.
[0097]
When the device output data is input to the device driver 4, it is determined whether there is a relative movement amount, that is, whether the pressing position data is 0 (step S1).
[0098]
Subsequently, it is determined whether or not the switch status data is the same as the switch status data included in the previously input device output data (step S2).
[0099]
If the pressed position data is not 0 or the switch status data is changed in step S1 or step S2, the device output data includes relative movement or tablet switch change information. It can be regarded as data.
[0100]
If it is change data, it is determined in step S3 whether or not the time from the already input dummy data is being measured. If the time is not measured, as in the conventional device driver 4, Data processing of this device output data is performed (step S4).
[0101]
The process of step S3 will be described later.
[0102]
In the data processing in step S4, the change data output from the coordinate input device 5 is input in the same data format as that of the mouse, so that it is regarded as mouse output data output from the mouse, and normal data processing is performed. Is called.
[0103]
That is, the pressed position data of the device output data is regarded as mouse relative movement data, position information for cursor control is formed based on the pressed position data, and mouse switch information is similarly formed from the tablet switch status data. .
[0104]
For example, when device output data including non-zero pressing position data (indicating that there has been a change in pressing position) is input, the X-direction pressing position data is stored in the CX register of the CPU as Y-direction position information. The pressing position data in the direction is loaded into the DX register as position information in the Y direction.
[0105]
If device output data including tablet switch status data different from the tablet switch status data input at the previous time is input, it is considered that the mouse switch status data has changed, and the tablet switch status data is stored in the BX register of the CPU. Is loaded as mouse switch information.
[0106]
Each time the change data is input in this way, the device driver 4 calls the OS 10 or the program 3 started by the personal computer 1 to read the data loaded in these registers, and causes the OS 10 or the program 3 to read the data. Sends position information and mouse switch information.
[0107]
In OS10 or program 3, from mouse switch information, position information, and their input intervals, in addition to relative movement operation, switch operation, etc., a mouse-specific operation mode such as click, double-click, drag, etc. is discriminated, cursor control, etc. Perform a predetermined operation.
[0108]
In step S1 and step S2, when the pressing position data of the device output data is 0 and the switch status data has not changed, the input device output data is regarded as dummy data, and the processes in and after step S5 Execute.
[0109]
With conventional mouse output data and device output data, these data are not output continuously unless the data changes. Therefore, when device output data consisting of the same data is input continuously, different information is output. Can be determined to be dummy data created to transmit to the personal computer 1.
[0110]
In step S5, it is determined whether the time from the already input dummy data is being measured. If not, the input dummy data is regarded as the first input dummy data, and time interval measurement from this dummy data is started (step S6).
[0111]
If the measurement is being performed, the process proceeds to step S7, and it is determined from the input pattern of the device output data whether the pseudo operation mode is set. In the pseudo operation mode, a plurality of device output data including dummy data is compared with a plurality of input pattern conditions shown in Table 2, and if any one of the conditions is satisfied, virtual mouse output data corresponding to the input pattern is input. It is what is considered to be.
[0112]
Table 2
[0113]
In step S3, even when device output data other than dummy data is input, it is determined whether the time from the already input dummy data is being measured. If the measurement is not performed, the data processing of step S4 is performed as described above. If the measurement is being performed, the process proceeds to step S8, and it is determined from the input pattern of the device output data whether or not the pseudo operation mode is set. .
[0114]
Hereinafter, the processing in step S7 and step S8 will be described with reference to Table 2 showing the input pattern conditions in the pseudo operation mode.
[0115]
Table 2 (a) shows that when new device output data is input, after dummy data is already input, t ₂ This is the case when the time more than the time has passed. t ₂ Is set to 1 second, for example.
[0116]
This dummy data is not intended to be input in the pseudo operation mode, and is invalid because it is input by accidentally pressing the tablet sheet 6.
[0117]
If the new device output data is dummy data, it is regarded as dummy data input for the first time, and the process proceeds from step S7 to step S6, and time interval measurement from this dummy data is started again.
[0118]
If the new device output data is change data, the time interval measurement is stopped, and the process proceeds from step S8 to step S4 to perform normal data processing.
[0119]
Table 2 (b) shows that the device output data including non-zero pressing position data is t ₁ And t ₂ It is a case where it is input within the time. t ₁ Is set to 25 msec.
[0120]
When the tablet sheet 6 is pressed and moved to the relative movement operation mode, dummy data is always output when the tablet sheet 6 is pressed as shown in FIG. The dummy data at this time is not generated to represent a mouse-specific operation mode, so that the relative movement operation mode is continued on the condition that device output data including non-zero pressing position data is continuously input. Judge.
[0121]
If it is determined that the operation mode is the relative movement mode, the time interval measurement is stopped, the process proceeds from step S8 to step S4, and normal data processing is performed.
[0122]
Table 2 (c) shows that new dummy data is t after the input of dummy data that has already been input. ₁ And t ₂ In the time of t _Four This is a case where no new device output data is input within the time. t _Four T ₂ Set to 1 second as in.
[0123]
When the tablet sheet 6 is tapped twice, this input pattern is generated. However, in order to distinguish it from the pseudo operation mode of double click and drag, t _Four If there is no new input after waiting for a time, it is determined that the mode is the single click pseudo operation mode. If it is determined in step S7 that the single-click pseudo operation mode is selected, the time interval measurement is stopped and the pseudo-operation mode data processing in step S9 is performed.
[0124]
Table 2 (d) shows that after dummy data is input twice, t2 after dummy data is input for the second time. _Three And t _Four This is a case in which new dummy data is input within the time. t _Three T ₁ Set to 25 msec.
[0125]
When the tablet sheet 6 is tapped three times, this input pattern is generated.
[0126]
In step S7, if there is an input satisfying the input pattern conditions in Table 2 (d), it is determined that the operation mode is a double-click pseudo operation mode, the time interval measurement is stopped, and the pseudo operation mode data processing in step S9 is performed. .
[0127]
Table 2 (e) shows that after dummy data is input twice, after the second dummy data input t _Three And t _Four This is a case in which change data is input within the time period.
[0128]
After tapping the tablet sheet 6 once, this input pattern is generated when the tablet sheet 6 is moved while being pressed.
[0129]
In step S8, if there is an input that satisfies the input pattern conditions in Table 2 (e), it is determined that the dragging pseudo operation mode is selected, the time interval measurement is stopped, and the pseudo operation mode data processing in step S10 is performed.
[0130]
Data processing in the pseudo operation mode in steps S9 and S10 will be described with reference to FIG.
[0131]
In step 9, after the second dummy data is input, t _Four If no new device output data is input even after a lapse of time, it is determined as a single click pseudo operation mode.
[0132]
Therefore, the single click data processing is executed after the second dummy data is input in the device driver 4 as shown in FIG. _Four It's time later.
[0133]
When the single-click pseudo operation mode is determined, it is assumed that the left switch of the mouse is clicked, and a series of virtual mouse output data shown in FIG.
[0134]
The mouse relative position data and mouse switch status data included in this series of virtual mouse output data is set to 0, and the mouse switch status data is set to 0 to match the data format of the mouse output data output by a single click. The pseudo mouse switch status data is the same as the mouse switch status data that changes in a single click.
[0135]
That is, as a result of a single click, the pseudo mouse switch status data changes as shown in (k) of the figure, so that the virtual mouse output data indicated by (nu) and (le) is 1 in FIG. Only the fifth bit of the byte changes, and the mouse output data in FIG. 7 becomes the same data as the mouse output data (A) and (B) in FIG. 7, respectively.
[0136]
If it is determined in step S7 that the double-click pseudo operation mode is selected, the left switch of the mouse is clicked twice in step S9, and a series of virtual mouse output data shown in FIG. It shall be assumed.
[0137]
The mouse relative position data and mouse switch status data included in this series of virtual mouse output data are set to 0 for the mouse relative position data to match the data format of the mouse output data output by double-clicking. Is the same pseudo mouse switch status data as the mouse switch status data that is changed by double clicking.
[0138]
That is, by double-clicking, the pseudo mouse switch status data changes four times as shown in FIG. 4 (k), and by this change, four virtual mice (W), (W), (F) and (Y) are displayed. It is assumed that the output data has been input.
[0139]
Since these virtual mouse output data are a series of virtual mouse output data corresponding to double-clicking, only the fifth bit of the first byte in FIG. 6A is changed alternately. ) And (f) are (nu), (wa) and (yo) are the same data as (le).
[0140]
If it is determined in step S8 that the dragging pseudo operation mode is selected, in step S10, the mouse is moved relative to the mouse while the left switch of the mouse is pressed, and a series of virtual mice shown in FIG. Assume that output data is input.
[0141]
Since the pseudo mouse switch status data in the drag mode always represents a state where the mouse left switch is pressed, the mouse switch status data included in the series of virtual mouse output data is a state where the mouse left switch is pressed, that is, Bit 5 of the first byte is “1”.
[0142]
As described above, since the drag is operated by first depressing the left switch, the first virtual mouse output data (data) is a bit of the first byte indicating the mouse switch status data as shown in FIG. 6B. Only 5 is “1”, and the mouse relative movement data is 0.
[0143]
A series of virtual mouse output data (re) and (seo) that are considered to be input subsequently correspond to the device output data (tu) and (ne) output as the tablet sheet 6 is pressed and moved, respectively. The pressed position data included in the device output data is mouse relative movement data of the corresponding virtual mouse output data.
[0144]
Accordingly, it is considered that virtual mouse output data equal to the number of device output data output by pressing and moving the tablet sheet 6 is input until the drag mode is exited. As described above, the mouse switch status data included in the series of virtual mouse output data is “1” indicating that the left switch is pressed down.
[0145]
As shown in FIG. 2, in order to exit this drag mode by an operation on the coordinate input device 5, the pressing of the tablet sheet 6 is once released, a tapping operation is performed again, and dummy data is generated.
[0146]
If this dummy data is entered when data processing is performed in the dragging pseudo-operation mode, the virtual mouse output is released as if the left switch of the mouse was pressed down and the mouse switch status data was changed to "0". It is assumed that data (a) has been input.
[0147]
A series of virtual mouse output data regarded as input in each pseudo operation mode is handled in the same way as mouse output data input from a normal mouse, and is the same data as the data processing in step S4 described above. Processing is performed.
[0148]
That is, the position information and mouse switch information formed based on the mouse relative movement data and the mouse switch status data are loaded into the CPU register at the output timing shown in FIG. Sent out.
[0149]
The OS 10 or the program 3 discriminates a click or double click, which is a pseudo operation mode unique to the mouse, from these position information and mouse switch information sent continuously, and executes corresponding processing.
[0150]
Accordingly, the tapping operation of the coordinate input device 5 represents predetermined information, and this information is transmitted to the OS 10 or the program 3 of the personal computer 1 without being confused with the device output data for outputting the change information of the coordinate input device 5. Can do.
[0151]
In the first embodiment described above, dummy data is output once every time the tablet sheet 6 is pressed. However, when releasing the pressing, dummy data is not output.
[0152]
Therefore, the pressing state of the tablet sheet 6 after the tablet sheet 6 is pressed and determined to be the pseudo operation mode is irrelevant to the pseudo operation mode.
[0153]
For example, even if the user taps twice and waits while releasing the press, or after tapping once and waits while pressing the tablet sheet 6, it is determined as a single click. It becomes an obstacle when combining operations.
[0154]
In order to solve this problem, the second embodiment outputs dummy data once when the tablet sheet 6 is pressed and continuously outputs dummy data twice when releasing the press. . The reason why the dummy data is output twice at the time of pressing release is to distinguish it from the dummy data output at the time of pressing, and the time interval between the two dummy data is a predetermined time interval t. _k And t _k Is set to a short time interval such as 10 msec that is not normally output so that it can be distinguished from other device output data.
[0155]
In the first embodiment, the dummy data is formed by the pressing position data and the tablet switch status data when the pressing of the tablet sheet 6 is detected. In the coordinate input device 5 according to the second embodiment, the dummy data is formed. Stores the data output as the device output data until the next device output data is output, and reads the stored device output data when the pressing or release of the tablet sheet 6 is detected to read the dummy data. Forming.
[0156]
The relationship between the operation of the coordinate input device 5 and the corresponding pseudo operation mode is that if the tablet sheet 6 is tapped once, the single click is performed, and if the tablet sheet 6 is tapped twice, the double click is performed. Then, each mode of the pseudo operation is associated with each other so as to be a drag.
[0157]
Table 3 shows the input pattern determination conditions for determining this pseudo operation mode from the input patterns in the second embodiment.
[0158]
Table 3
[0159]
That is, Table 3 (a) shows that after inputting dummy data, t ₁₂ In this case, no new device output data is input, and the input dummy data is invalid as an erroneous input.
[0160]
Table 3 (b) shows t after inputting dummy data. ₁₁ And t ₁₂ This is a case where device data output data including change information is input during the period. If the tablet sheet 6 is pressed and moved while being pressed, this input pattern is obtained, so that it is determined as a normal relative movement operation.
[0161]
Table 3 (c) shows t after inputting dummy data. ₁₁ And t ₁₂ During this period, dummy data is input and t _k After inputting dummy data continuously at time intervals of t, t ₁₃ This is a case where no new device output data is input for a period of If the device driver 4 has an input pattern that satisfies this condition, it is determined as a single-click pseudo operation mode. t _k Since the dummy data is input twice at the time interval, it is not determined that the tablet sheet 6 is single-clicked simply by tapping once and then pressing the tablet sheet 6.
[0162]
Table 3 (d) shows the input pattern of Table 3 (c). ₁₃ Is the same input pattern as in Table 3 (c) starting with one dummy data. If there is an input pattern that satisfies this condition, it is determined as a double-click pseudo operation mode. As in the case of a single click, unless the second press of the tablet sheet 6 is released, continuous dummy data is not output, so that it is not determined as a double click.
[0163]
Table 3 (e) is the input pattern of Table 3 (c), and t ₁₃ This is a case in which device data output data including change information is input while waiting for a predetermined time. When device output data is input in an input pattern that satisfies this condition, it is determined that the dragging pseudo operation mode is selected. Then t ₁₃ If the continuous dummy data is input at the time interval of, it can be seen that the pressing of the tablet sheet 6 has been released, and the drag mode is exited.
[0164]
Therefore, it is not necessary to newly tap the tablet sheet 6 as in the first embodiment, and the drag mode can be ended.
[0165]
The present invention can be variously modified without being limited to the above embodiment.
[0166]
For example, the dummy data is output when the tablet sheet 6 is pressed, but may be output only when the pressing is released.
[0167]
In addition, when the pressing of the tablet sheet 6 is detected or when the pressing is released, the dummy data is output once or twice. However, if the number of times is predetermined, the number of times can be set to an arbitrary number.
[0168]
In the above embodiment, the number of times dummy data is output and the timing indicate click, double click, and drag, which are mouse-specific operation modes. However, the present invention is not limited to this, and various information is transmitted to the personal computer 1. Can do.
[0169]
For example, if the pressing operation of the tablet switch provided in the coordinate input device 5 is represented by the number and timing of the dummy data output by pressing and releasing the tablet sheet 6, the tablet switch is not necessarily applied to the coordinate input device 5. There is no need to provide it.
[0170]
Furthermore, in the above embodiment, the pseudo mouse switch status data represents the mouse switch status data of the left mouse switch in the pseudo operation mode, but may represent the mouse switch status data of the right mouse switch. In particular, since this data is automatically created in the pseudo operation mode, it can be easily changed only by changing the program 3 of the device driver 4.
[0171]
Therefore, even if it is set to perform a mouse-specific operation by operating the right mouse switch for the left-handed user by the program 3 or the OS 10 started on the personal computer 1, the pseudo mouse switch status data is used. If the mouse switch status data of the right switch of the virtual mouse output data is represented, the pseudo operation mode can be represented by the tapping operation of the tablet sheet 6 as in the above embodiment.
[0172]
Furthermore, although the position detection means of the coordinate input device 5 of the above embodiment has been described as forming a uniform potential gradient on the tablet sheet and detecting the pressing position of the tablet sheet 6 from the potential at the pressing position, You may detect the position by the method similar to the position detection means in the other conventional tablet. For example, when a finger or the like is brought close to the tablet sheet 6, position detecting means for detecting an approach position to the tablet sheet 6 from the electrostatic capacity that changes at the position may be used. When employed, the operation position approaching the tablet sheet 6 becomes the pressing position of the tablet sheet 6.
[0173]
【The invention's effect】
According to the present invention, the pseudo operation mode can be expressed by the number of times the tablet sheet 6 is pressed or released, and the timing, so that the coordinate input device 5 is used instead of the mouse, and mouse-specific operations such as click and drag are performed. Can be entered with one hand.
[0174]
Further, since the determination of the pseudo operation mode is not performed in the coordinate input device 5, the coordinate input device 5 does not need to include a determination unit, and the coordinate input device 5 can be downsized.
[0175]
In addition, by outputting dummy data at a timing that is not originally output from the mouse, it is confused with mouse output data and device output data including change information while maintaining compatibility with the mouse and the coordinate input device 5. In addition, further information can be transmitted from the coordinate input device 5 to the personal computer 1.
[0176]
In particular, when extra data cannot be included in the output format of the device output data, other types of data can be output without changing the output format.
[0177]
Since the device driver 4 of the personal computer 1 compares the input pattern and the input pattern condition in the pseudo operation mode, the input pattern condition can be easily changed by the program 3. . Therefore, the coordinate input device 5 does not need to be provided with an input circuit or a change circuit for changing the input pattern condition, and can be changed without performing two-way communication with the personal computer 1.
[0178]
Also, the relationship between the input pattern and the pseudo operation mode can be easily changed by changing the program 3 of the device driver 4.
[0179]
Therefore, even if it is set to perform a mouse-specific operation by operating the right mouse switch for the left-handed user by the program 3 or the OS 10 started on the personal computer 1, the pseudo mouse switch status data is used. If the mouse switch status data of the right switch of the virtual mouse output data is represented, the pseudo operation mode can be represented by the tapping operation of the tablet sheet 6 as in the above embodiment.
[0180]
In particular, according to the first aspect of the present invention, if the pseudo operation mode is the operation of the tablet switch and the status of the tablet switch is expressed by the tapping operation of the tablet sheet 6, it is not always necessary to provide the coordinate input device 5 with a switch.
[0181]
According to the fourth aspect of the present invention, it is possible to determine when the tablet sheet 6 is pressed and when the tablet sheet 6 is released based on the number of times of output of the dummy data. The pressing state can be included, and further different pseudo operation modes can be determined in advance.
[0182]
Further, after the tablet sheet 6 is pressed and dragged in the pseudo operation mode, the drag mode can be exited only by releasing the pressing without tapping.
[0183]
According to the inventions of claims 5 and 6, the device output data composed of the same data continuously from the conventional coordinate input device 5 is simply output as dummy data. Data can be output to the personal computer 1.
[0184]
Further, since the dummy data output from the coordinate input device 5 is composed of the same data as the device data output immediately before, the dummy data does not have means for discriminating from normal mouse output data or device output data. Even if it is input to the conventional device driver 4, it does not cause a malfunction.
[0185]
Therefore, the coordinate input device 5 according to the present invention can be used by being connected to the conventional personal computer 1.
[0186]
According to the sixth aspect of the present invention, when the pressing of the tablet sheet 6 is detected, neither the tablet switch status data nor the pressing position data is changed by the pressing. Can be formed.
