Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an input method of a data input device of a computer, and more particularly to a coordinate input device (tablet) among the input devices of the computer.

[0002]

2. Description of the Related Art In a conventional tablet input device, coordinate value data input from an input surface is used as data to be output as it is. Further, in the prior art, in order to perform a double tap input, a method has been adopted in which a human repeatedly performs the input many times, or an application program that can be used without the double tap input.

[0003]

A double tap on such a conventional tablet input device corresponds to a double click with a mouse. Double-clicking the mouse requires pressing the button twice under the condition that the coordinate value of the mouse pointer does not change. On a tablet, pressing a pen on the tablet corresponds to pressing a mouse button. Therefore, in order to perform an operation similar to double-clicking, the same coordinates must be pressed twice consecutively. However, it is difficult for a person to press the exact same point continuously.

[0004] The present invention eliminates the above-mentioned problems, and determines whether or not a double tap is performed even if a person does not press the same coordinates continuously in succession. An object of the present invention is to provide an auxiliary method of tap input.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides: (1) a clock unit and a tablet input unit connected to the clock unit in an auxiliary system of double tap input in a tablet input device. An input coordinate register connected to the tablet input unit, a pen state storage register connected to the tablet input unit, and a clock unit connected to the input coordinate register and the pen state storage register. A double tap recognizing unit, and an output coordinate register connected to the double tap recognizing unit. If the double tap recognizing unit determines that the double tap is in progress, the previous data is stored in the output coordinate register. Then, the value held by the output coordinate register is output.

[2] In the double tap input assisting method according to the above [1], if the coordinate shift between two pen presses in the double tap recognition unit is equal to or smaller than a predetermined value, it is determined that the double tap is in progress. It is intended to be recognized. [3] In the double tap input assisting method according to the above [1], if the time interval between two pen presses in the double tap recognition unit is equal to or less than a predetermined time, it is recognized that the double tap is in progress. It was done.

[4] In the double tap input assisting method according to the above [1], the coordinate shift between two pen presses in the double tap recognition unit is equal to or less than a predetermined value, and If the time interval between two pen presses is equal to or less than a predetermined time, it is recognized that a double tap is in progress. [5] In the double tap input assisting method according to [1], [2], [3] or [4], the reference value for determining whether or not double tap is in progress in the double tap recognition unit is variable. It can be set.

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a block diagram of a tablet input device according to an embodiment of the present invention.
As shown in this figure, the clock unit 6 is a tablet input unit 1
And the double tap recognition unit 4. Further, the tablet input unit 1 stores the input data in the input coordinate register 2 and the pen state storage register 3. The input coordinate register 2 stores a coordinate value at which the pen exists, and the pen state storage register 3 stores "the pen is away", "the pen is in contact", and "the pen has just contacted". , Any state of “pen is just off” is saved.

The double tap recognition unit 4 obtains data from the input coordinate register 2, the pen state storage register 3, and the clock unit 6, and stores the processing result in the output coordinate register 5. Then, the data stored in the pen state storage register 3 and the data stored in the output coordinate register 5 are output from the tablet input device. Next, the operation of the tablet input device will be described.

The tablet input unit 1 uses the clock unit 6 to periodically detect a pen, obtains coordinates of the pen and the state of the pen, stores coordinate data in the input coordinate register 2, Is stored in the pen state storage register 3. The double tap recognition unit 4 obtains coordinate data from the input coordinate register 2, obtains pen state data from the pen state storage register 3, and uses these data, the previously output coordinate data, and the pen state data. It is determined whether or not the current input data is data in which double tap input is in progress. If the data is data in which double tap is in progress, the previously output coordinate data is stored in the output coordinate register 5 and double tap is in progress. If not, the data obtained from the input coordinate register 2 is stored in the output coordinate register 5.

The data stored in the pen state storage register 3 and the data stored in the output coordinate register 5 are output data from the tablet input device. Here, the fact that the double tap input is in progress is determined inside the double tap recognition unit 4, and the method of determination is arbitrary. With such a configuration, the same coordinate value is output while the double-tap input is in progress by the operation of the double-tap recognition unit 4, so that even if a person shifts the pressing coordinates of the pen during the double-tap input, The effect of being recognized as a double tap is obtained.

Next, the configuration of the double tap recognition unit of the tablet input device will be described. FIG. 2 is a block diagram of the double tap recognition unit showing the first embodiment of the tablet input device of the present invention.

And the same data as output is stored in the previous output coordinate data register 8. The double tap in progress flag register 12 is a register that stores whether or not a double tap is in progress.

Next, the operation of the double tap recognition unit of the tablet input device will be described. The coordinate data difference calculator 9 calculates the difference between the data obtained from the current input coordinate data register 7 and the data obtained from the previous output coordinate data register 8, and outputs the difference to the determination unit (coordinate difference method) 11.

If the data stored in the double tap progress flag register 12 is not “double tap in progress”, the judgment section (coordinate difference method) 11 determines whether the current pen state data register 10 With reference to the value, it is determined whether or not “the pen has just touched” (step S5). As a result, if "the pen has just touched", the data indicating that the double tap is in progress is set in the double tap in progress flag register 12 (step S6), and it is determined that the double tap is not in progress (step S6). S7). If it is not "pen just touched" in step S5, it is determined that the double tap is not in progress (step S7).
