DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] 1. Field of the Invention [0002] The present invention relates to a device for inputting by pen or touch such as a tablet.

[0002]

2. Description of the Related Art A tablet or digitizer for designating a position within a screen and detecting and inputting the designated coordinates is called a pointing device or a coordinate input device. Often used for

Data input by a pen and a tablet can have both functions of a keyboard as a data input device and a mouse as a pointing device. Further, a system in which a transparent tablet is superimposed on a screen of a display device using a liquid crystal or the like is widely used as a device having excellent operability.

[0004] A pointing device such as a mouse is usually provided with a switch. This switch is often used to move a cursor with a mouse or the like and to determine a command at that position. On the other hand, in many cases, the pen performs the finalizing operation by touching or lightly pressing the screen.

[0005] In the operation of switches, an operation called double click is frequently used recently. Double-clicking is a method of operating the switch twice within a short time.
When performing this double click with a pen, it is necessary to press the pen twice at the same position on the tablet.

[0006]

However, as described above, the operation of pressing the pen twice at the same position on the tablet as described above tends to shift the position of the pen, and is often processed as simply specifying the position twice.

Japanese Patent Laid-Open No. 5-158608 discloses a means for solving this problem. JP-A-5-15860
In Japanese Patent Application Laid-Open No. 8 (1999) -1995, as a means for solving the above-mentioned deviation, the distance between the coordinate position P1 when the pen tip is pressed for the first time and the coordinate position P2 when the pen tip is pressed for the second time is set value e. And the time from when the pen tip is pressed for the first time to when it is pressed for the second time is within a predetermined range, it is determined to be a double click.

Normally, the data input area for icons and the like is on the X axis,
There is a rectangular area having a certain width in the Y-axis direction. However, in Japanese Patent Application Laid-Open No. 5-158608, the pen position allowable range area (the area determined to be double-clicked) becomes a circular area having a radius e, which may impair visual operability.
If the set value e is set to a large value, a difference occurs between the data input area and the pen position allowable range. If the set value e is set to a small value, the operation range becomes difficult because the allowable range is invisible.

The present invention solves the above problems,
It is visually secure and allows for easy double-clicking.

[0010]

According to a first aspect of the present invention, there is provided a tablet for inputting coordinates by a pen or a touch input, and a display device configured to overlap the tablet and display a plurality of data input areas. When the first coordinate P1 is input to the tablet and the second coordinate P2 is input to the same data input area as the first coordinate P1 within a predetermined time T, the input is performed. The above problem is solved by providing a double-click determining means for determining a double click at the first coordinates P1.

According to a second aspect of the present invention, there is provided a display-integrated tablet comprising a tablet for inputting coordinates by a pen or a touch input, and a display device configured to overlap the tablet and display a plurality of input areas. When the first coordinate P1 is input to the tablet, and the second coordinate P2 is input within a predetermined range in the X and Y axis directions from the data input area to which the first coordinate P1 belongs within a predetermined time T. The above problem is solved by providing a double click determining means for determining that the input is a double click at the first coordinates P1.

According to a third aspect of the present invention, there is provided a display-integrated tablet comprising a tablet for inputting coordinates by a pen or a touch input, and a display device configured to overlap the tablet and display a plurality of input areas. When the first coordinate P1 is input to the tablet and the second coordinate P2 is input within a predetermined range in the X and Y-axis directions from the first coordinate P1 within a predetermined time T, The above-described problem is solved by providing a double-click determination unit that determines a double click at one coordinate P1.

According to a fourth aspect of the present invention, the first aspect is provided.
In the input device according to any one of (1) to (3), the above problem is solved by including a tablet range display unit that displays a range determined as a double click on the display device when the first coordinate P1 is input.

2, y1) and D (x1, y1). At this time, the effective range of the double click is an area surrounded by four points A, B, C, and D. In step S17, the CPU 11 compares the x coordinate and the y coordinate of P2, A, B, C, and D. That is, x1 ≦ X2 ≦ x2,
If y1 ≦ Y2 ≦ y2, it is determined that P2 belongs to the effective range of double click, and is recognized as a double click of P1. Otherwise, it is determined that it does not belong to the effective range. The basic processing other than the effective range of the double click is the same for the examples of FIGS. 7, 8, and 10.

[0039]

As described above, according to the present invention, two pen tip presses or two touches are in the same input area,
In addition, when the time from the first operation to the second operation is within a predetermined time, the input processing is performed as a double-click, so that the same function as the mouse double-click can be realized with a pen or a touch input. In addition to eliminating the problem of misalignment that is likely to occur with input, double-clicking with two separate points (for example, double-clicking by double-touching the index finger and the middle finger) can be realized, and secure and easy double-click input can be performed. It is possible to obtain.

Further, by expanding the predetermined range from the first data input area to a double-click effective range, even if the input area is small, the double-click can be performed reliably and easily.

Further, by displaying the range determined to be a double click, the effective range of the double click can be visually checked, and the double click input can be performed reliably and easily.
