Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a touch screen input device.

[0002]

[Prior Art]

 As one of the display / input methods of the man-machine interface in various systems using a computer, there is a touch screen input device in which a touch screen is superposed on the surface of a flat panel display such as a CRT or a liquid crystal display (LCD).

As a parameter input (especially numerical value input) method on the touch screen, generally, a method of displaying a virtual keyboard on the touch screen and inputting by intermittent key touch as shown in FIG. 5A is used. Has been.

In addition, when a parameter such as the input numerical value is continuously changed after inputting the numerical value or the like, the touch screen is left and the rotary knob or cursor (not shown) as shown in FIG. 5B is used. ) And other input devices.

[0005]

[Problems to be solved by the device]

 In the above-mentioned conventional touch screen input method, it is necessary to perform a plurality of intermittent operations of the key to set desired parameters, which makes the input operation (especially inputting a large numerical value) troublesome. Also, relying on other devices in the case of continuously changing input parameters will eventually hinder the use of the touch screen.

The present invention has been made in view of the above-mentioned problems of the conventional technology. The purpose is to improve the input performance of parameters by utilizing the characteristics of the flat display of the touch screen. It is in.

[0007]

[Means for Solving the Problems]

 The touch screen input device of the present invention has a slide input area provided in a part thereof, and the touch screen with the relative distance between the position of the finger placed in the slide input area and the reference point as a parameter. And a display control means for changing the display.

[0008]

[Action]

 The display parameters can be continuously changed by adjusting the shift amount of the finger in the slide input area. As a result, it is possible to perform an analog-like input that can be visually grasped, and the input performance is improved.

[0009]

【Example】

 Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a diagram showing the configuration of an embodiment of a touch screen input device of the present invention.

The touch screen 1 is laid on the display device 2, and a slide input area 3 extending in the horizontal direction is provided at the bottom of the touch screen 1. The touch of the operator's finger on the touch screen 1 (including the slide input area 3) is detected by the touch position detection means 4, and the detection signal is input to the control device 5.

The control device 5 detects a relative distance between the touch position of the operator and the reference point, a relative distance detecting means 6, an arithmetic control means 7 for executing a predetermined control arithmetic operation based on the detected relative distance, and an output. The interface 8 is provided, and a signal for giving a parameter change according to the relative distance between the touch position and the reference point is sent from the output interface 8 to the display control device 10 and the peripheral device 9. There is. The calculation mode of the calculation control means 7 is designated by the mode designation means 12. The display control circuit 10 displays and changes the parameters on the display 2 while referring to the data file 11.

An example of use of this embodiment is shown in FIGS. In the case of FIG. 4, the left end of the slide input area 3 is set as a reference point (0%) 40, and the parameter amount is input and changed according to the distance from the reference point 40 to the finger touch position 50. For example, in the numerical value input mode, you can input and change numerical values, and in page scroll mode, you can update pages sequentially from page 1.

3A to 3C show examples of the pointer movement mode, in which the pointer 200 is moved by shifting the finger. In this example, the moving direction of the pointer 200 can be specified by the shift direction of the finger placed in the slide input area 3, and the moving speed can be specified by the relative distance from the reference point 4. That is, as shown in (a), the pointer 200 moves to the right direction at higher speed as the finger is placed on the reference position 4 in the middle and is shifted to the right as shown in (b) and (c). .. In this way, it is possible to make an analog input that can be grasped visually, and to input efficiently.

FIG. 2 is a flowchart showing an example of the basic operation procedure of this embodiment. First, the touch position detection means 4 detects the touch position coordinates (step 100), and determines whether the input is from within the slide input area (step 101). If the input is from outside the slide input area, it is a separate process. If the input is from within the slide input area, the information is sent to the relative distance detecting means 6 to detect the relative distance between the reference point and the touch position. (Step 102).

Next, the arithmetic control unit 7 calculates the parameter change amount (or display amount) based on the obtained relative distance (step 103), and the control signal (display command) based on the obtained value. ) Is output via the output interface 8 (step 104), and a predetermined display is performed.

As described above, in the present embodiment, the moving speed control, the change control of the numerical parameters, the direct numerical input, and the like are performed using the distance between the fixed point (reference point) and the fingertip as a parameter. Therefore, all operations can be performed on the touch screen, there is no need to move the device, and there is no need to keep moving the hand like when using the rotary knob.

[0017]

[Effect of the device]

 As described above, in the present invention, the control amount is made visible from the distance between the fixed point and the fingertip, so that analog control close to human sense can be performed, and it is originally suitable for intuitive operation. Input that makes full use of the input characteristics of the touch screen is possible. In addition, the need for a separate input device such as a rotary knob is eliminated, making input operations easier.
