[0010]

FIG. 1 shows an embodiment of the present invention, in which an information processing apparatus (computer 10) to which the present invention is applied.
It is a block diagram which shows the whole schematic structure of 9). Here, in the display measure 112, the touch panel 111 is mounted on the display body 110, and the display range of the display body 10 and the coordinate range of the touch panel match each other.

The computer 109 includes a CPU 101 and an R
An AM 102, a ROM 103, a keyboard interface 104, a mouse interface 105, a printer interface 106, an HDD / FDD 107, and an expansion slot 108 are provided. The mouse transparent touch panel device 113 is supplied with power via the expansion slot 108 and is connected to the mouse interface 105 and the touch panel 111.

FIG. 2 shows an example of the signal output by the mouse. The mouse has a ball on the bottom of the main body, and has two sensors for obtaining the movement amount of the ball. When the mouse is moved, the ball rolls and signals with different phase differences are output. Whether the direction is the + direction or the − direction is recognized based on the phase difference, and the movement amount can be obtained by the number of output pulses. In addition, the mouse is provided with left and right switch buttons, and pressing the switch (click) turns it on / of.
It is sent to the computer as an F signal.

FIG. 3 shows a touch panel coordinate diagram, and the touch panel displays the coordinate data pressed by a finger as X (X1, X2 ... Xn), (Y1, Y2 ... Y) as shown in FIG.
It is output as the coordinate data of n). In this way, the mouse outputs movement amount and click information as a coordinate input method,
Since the touch panel outputs coordinates, the touch panel cannot be directly connected to the mouse interface.

FIG. 4 is a block diagram showing the configuration of the embodiment of the present invention. A coordinate data input unit 401 for receiving coordinate data from a touch panel which is a coordinate input device, a main part for controlling the mouse transparent touch panel device of the present invention. Control unit 4
02, a data conversion unit 403 for converting the coordinate data of the touch panel into data of the amount of movement of the mouse, a mouse data output unit 404 for outputting the converted mouse data to the mouse interface of the computer, and a unit for receiving data from the mouse. The mouse data input unit 405 is provided.

FIG. 5 is a flowchart showing the processing procedure when the touch panel of the present invention is used as a mouse. When the touch panel, which is the coordinate input device, is designated with a finger, the coordinate data of the touch panel is converted into the coordinate data input unit 4.
01 is input (step S1). Next, step S
2, the coordinate data input unit 401 that has received the coordinate data sets the coordinate data input in step S1 to X, Y.
Detect by dividing into coordinates (input coordinate data is Xa,
Ya)). When the coordinate data input unit 401 detects the coordinate data, the coordinate data input unit 401 notifies the main control unit 402 that the data has been input from the touch panel, and sends the detected coordinate data to the main control unit 402. Coordinate data input unit 401
In response to the notification from the main control unit 402, in order to position the mouse cursor, the main control unit 402 notifies the mouse data output unit 404 to output the maximum negative value of the mouse movement amount to the mouse interface of the computer (step). S3).

Mouse data output unit 404 that received the notification
Outputs the maximum value of the mouse data held in advance to the mouse interface of the computer. As a result, the position of the cursor is the origin (X1,
It moves to Y1) (step S4). Here, the reason for moving the cursor of the mouse to the origin (cursor reset) is that if the cursor is not reset, the application software (AP) of the computer moves the cursor of the mouse on the software and stores the stored coordinates. This is because the current position of the cursor of the mouse will not match and the coordinates of the touch panel and the coordinates of the mouse will be displaced, and the mouse will not operate normally. However, when the AP does not move the cursor or when the initial coordinates of the mouse cursor are known, it is not necessary to reset the cursor, and therefore the operation can be speeded up.

Next, the main control section 402 receives the touch panel coordinate data (X
a, Ya) is sent to the data conversion unit 403. Upon receiving the coordinate data, the conversion unit 403 converts the coordinate data of the touch panel into the movement amount data for the mouse and sends it to the mouse data output unit 404. The method of calculating the movement amount data here is X = Xa−X1, where the movement amounts are X and Y,
Y = Ya−Y1. (Step S5) Normally, in order to calculate the movement amount, it is necessary to detect the current mouse cursor position. However, since the mouse cursor position is once moved to the origin, it can be found from the above-described calculation formula. As described above, the movement amount can be calculated only by the coordinate data input from the touch panel. Upon receiving this mouse data, the mouse data output unit 404 outputs it as mouse pulse data to the mouse interface of the computer (step S6).

The above is the description of the operation of outputting the movement amount of the mouse, but the mouse needs to control the left and right click buttons as described above. First, in the commonly used left-click operation, it is understood that when the touch panel is pressed with a finger, coordinate data is input to the touch panel coordinate data input unit 401 and the touch panel is pressed. Upon receiving this information, the main controller 402 receives the mouse data output unit 40.
4 is notified to output the information of left click ON at the same time as the output of the data of the movement amount of the mouse. Next, when the finger is released from the touch panel, the coordinate data will not be input to the touch panel coordinate data input unit 401.
The touch panel coordinate data input unit 401 includes the main control unit 40.
Notify 2 of the information. The main control unit 402 which received this information left-clicks on the mouse data output unit 404.
Notify to output FF information. In this way, left click can be recognized, but there are two (left and right) from the nature of the touch panel (only the action of pushing or releasing the panel).
Since it is difficult to distinguish the switches, the right click is recognized by the speed at which the touch panel is pressed. For example, when the touch panel is pressed again within a certain time (short time) after the touch panel is released, it is recognized as a right click, and the main control unit 402 causes the mouse data output unit 40 to
4 is notified to output the information of right-click ON.

By such a series of operations, the computer can move the cursor of the mouse as if using the mouse.

The above description is for a pulse control type mouse as a mouse interface, but the specification of the data output section of the mouse is also changed for a bus mouse, a serial mouse, etc. which are generally used as a mouse interface for computers. It is possible to cope by doing.
In addition, the mouse input unit 40 of the mouse transparent touch panel device
Connect a normal mouse to 5, and use mouse data output unit 404
By combining the mouse data generated by converting the touch panel coordinate data with the mouse data from the normal mouse, it is possible to use the touch panel and the mouse together.

From the coordinate data input from the touch panel of the coordinate input device, the movement amount data required by the mouse interface is calculated and directly output to the mouse interface of the computer.

[0022]

As described above, in the mouse transmissive touch panel device of the present invention, the coordinate data of the touch panel can be converted into the pulse data of the mouse and directly output to the mouse interface (mouse connector) of the computer. By only preparing a display device with a built-in touch panel, an existing computer can use the touch panel like a mouse without using special software (touch panel driver).
