Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an information input device for inputting data interactively with a computer, such as a personal computer or an interactive NC.

[Prior Art] Various methods of inputting data into a computer have been considered in the past, but the current common data input method is a method using a CARI screen and a keyboard.

There is also a method in which a menu is displayed on the first screen of the CRT iu and information is input by pressing the corresponding function keys.

[Problems to be solved by the invention] In the conventional data input method as described above, the operator
It was inefficient to have to work by looking at both the RT screen and the selection keys.

The present invention has been made to solve such problems, and an object of the present invention is to provide an information input lid that allows an operator to input data simply by looking at a CRT screen without looking at his/her hand.

[Means for Solving the Problems] The information input device according to the present invention includes a display memory for displaying stored information as an image, a display device for displaying the contents of the display memory as image information, and a display device for displaying the contents of the display memory as image information. It has an input device for inputting the position and shape of the hand and the position pressed by the worker, means for displaying a menu to be selected by the worker on the display device, and means for inputting the position and shape of the worker's hand. The apparatus includes means for inputting an operator's hand using an input device and displaying the operator's hand on the display device.

[Function] According to the information input device of the present invention, the menu is displayed by the display memory, the movement of the worker's hand can be monitored on the same screen, and the menu on the screen and the pressed position of the input device can be The operator can select from the menu by matching the .

[Embodiment FIG. 1 is a schematic diagram showing an embodiment of the present invention. (
1) is a CRT display device, (2) is an input device that detects the position and shape of the worker's hand as well as the position pressed by the worker, (3) is the displayed menu, and (4) is the displayed menu. This is a hand-made video.

FIG. 2 is an internal configuration diagram of an apparatus according to an embodiment of the present invention. In the figure, (lot) is the main memory that programs the operation of the CPU (102), and (102) is the central processing unit that writes and reads data into the frame memory (103) and accepts interrupts from the touch panel (201). device, (103) is a frame memory that stores image information, (104) is a frame memory (10
3) and an address generation circuit that inputs addresses one after another to the image sensor; (105) is a C that generates dot clock signals and horizontal and vertical synchronization signals necessary for image display to the address generation circuit and color palette (107);
The RT timing generator (106) is a data selection circuit (1
07) is a color palette that receives an input address and outputs a video signal RGB based on color information written in advance at the corresponding address.

(201) is a touch panel in the input device (2) which, when pressed by the worker, writes an interrupt to the CPU (102) and notifies its position, and (202) is an image sensor that outputs an image of the worker's hand. It is.

FIG. 3 is a circuit diagram of the data selection circuit (106). When the output of the image sensor is logic H, all outputs of the color palette become logic H, and in other cases, the data from the frame memory remains unchanged. Output to color palette.

FIG. 4 shows another embodiment of the input device.

Transparent touch panel (201) and image sensor (
202) are integrated and bonded together.

With such a configuration, it is possible to simplify and reduce the weight of the input device.

FIG. 5 is a circuit diagram showing an example of an image sensor (202), where (21) is an address converter that supplies row and column addresses to multiplexers (22) and (23) when an address is input. be. (22) and (23) are switch-operated multiplexers that select each row and column and connect the detection terminals to the sensor elements (24) corresponding to the rows and columns, and (24) are arranged in a grid pattern. The sensor elements are connected in the same row and column as shown in the figure.
The sensors used include optical sensors, temperature sensors, and electrostatic sensors.

The operation of the embodiment configured as described above will be explained below.

In FIG. 2, a menu to be displayed is stored in a frame memory (103), or this rewriting is performed by a central processing unit (102). A CRT timing generator (105) and an address generation circuit (104) output pixel-by-pixel addresses on a scanning line to an image memory (202) and a frame memory (103). At this time, the address of the image memory (202) can generally be rough, so if the lower bits of the output address are ignored, the frame memory (10
The output address to 3) can be used as is.

The data selection circuit (106) is the image sensor (20
Since priority is given to the output of 2), the image sensor (202
), the input to the color palette (107) will be //FF //, and the pixel will be llFF
It is written at address 11 and becomes the color of the data in the color palette.

If there is no output from the image sensor (202), the data in the frame memory (103) is directly input to the color palette (107).

Therefore, data in the frame memory (103) (for example, menus, etc.) is normally displayed on the CRT display.
is being output, but the operator is using the image sensor (20
2) If the worker moves his/her hand, an image of the worker's own hand will be displayed on (K).

Then, by making the touch panel (201) correspond to the menu in the frame memory (103), when the operator presses the touch panel (201), an operation will be displayed on the CRT display as if he had selected an actual menu. I can highly doubt it.

Furthermore, by bonding a flat sensor as shown in Fig. 5 with a touch panel (201) as shown in Fig. 4, it is possible to create a one-to-one correspondence between the screen and the input device (2). , 414 input devices can be constructed compactly.

Note that the menu to be output on the screen can be freely created, so if the keyboard pattern is displayed as a menu, a conventional keyboard is no longer necessary.

Note that the input device used in the present invention may be composed of a camera and a touch panel.

In addition to the optical sensor, the image sensor may also be a temperature sensor or an electrostatic target sensor, and in this case, no illumination is required and the image sensor can operate in the dark.

By the way, it goes without saying that the present invention can be used not only for burner computers but also for interactive NCs, workstations, televisions, and the like.

[Effects of the Invention] As explained above, according to the present invention, the worker can check the worker's hand movements on the display screen, select menus displayed on both sides of the same display, and the worker can It is possible to create a system with a simple configuration that allows work to be done without looking at the screen and with extremely high operability.
