[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a remote coordinate input device for performing remote operation to input coordinates.

[0002]

2. Description of the Related Art Conventionally, in fields such as office automation and process automation, an icon such as a pull-down menu is displayed on the screen and the icon is used by a coordinate input device such as a mouse in order to improve the operability of the operator. It has been performed such that an operator makes a selection and develops it on a desired screen.

By doing so, even an operator unfamiliar with the key operation or an operator who is not familiar with the operation method can easily and accurately operate the key.

According to this method, the next operation can be performed without a manual as compared with the method of tapping a plurality of keys from the keyboard to open the screen on the next screen, thereby improving the operability.

[0005]

In recent years, especially in the field of process automation, there are increasing cases where a video projector is required as a replacement for a graphic panel.

[0006] The operator of the plant had the old plant as a whole, but the CRT display in which all the graphic panels that allow a panoramic view of the situation were integrated on the console. It is said that he has anxiety without understanding.
The only way for the administrator to know the operating status of the current plant is to operate the console and check the displayed screen, as with the operator.

Since it is desired to monitor and operate the screen for the above-mentioned purpose in managing the plant, complicated operation is not required, and it is often sufficient to call a specific screen with one touch. However, I want to operate a large video projector that can replace the graphic panel that can be seen from any position in the room from anywhere in the room and display the desired screen.

However, there is a problem that a coordinate input device represented by a mouse, a trackball or a touch screen can be used only near the display device. That is, it is impossible to operate the screen of the video projector at a remote place.

An object of the present invention is to provide a remote coordinate input device which can be remotely operated from one's own seat or the like, which is slightly away from the user.

The plant is operated while observing a screen showing a plant operation status displayed on a display device typified by a CRT display incorporated in the plant. A large screen 1 is installed on the front wall of the operator, and a part of the screen monitored by the console 2 can be displayed. However, the administrator 205 usually does not directly operate the screen 1. However, the administrator 205 has the remote control device 6 and operates the screen by emitting a signal (usually an infrared ray or a signal) from the remote control device 6 toward the coordinate detecting device 4 installed near the screen 1. You can

Next, using the remote control device 6, the administrator 2
A method of operating the screen 05 displayed on the screen 1 will be described.

The console 2 has the information collected from the plant via the transmission device and the network, and displays the necessary information on the CRT display incorporated by operating the console. The video signal output from this display circuit is input to the (video) projector controller 3 via the signal line 2C. The projector controller 3 projects an image on the screen of the screen 1.
The administrator 205 operates the remote control device 6 to select a screen to be viewed. A signal such as infrared ray 2b emitted from the remote control device 6 is detected by the coordinate detection device 4 installed near the screen 1. Since the coordinate detection device inputs the data to the console 2 via the input signal line 2b, a desired screen selected by the administrator 205 operating the remote controller 6 is displayed on the screen.

FIG. 2 is a plan view showing an embodiment of the remote control device, FIG. 3 is a front view, and FIG. 4 is a side view. In this example,
This is an example of a remote control device incorporating an infrared LED, and light emitted from the infrared LED is emitted from an emission window 402. That is, when the key 401 is operated, infrared light modulated by the code corresponding to each key is emitted from the emission window 402.

In this embodiment, 16 keys are incorporated in the key operation portion, but the number function of these keys can be increased or decreased as necessary. For example, a key for operating multiple screens in a page-turning sequence, a SEL key for selecting multiple display devices (similar to a TV channel selection key), an alarm sound when an alarm is issued. Key to use when resetting or checking the contents,
A key to call the cursor when operating the icon with the cursor, a cursor operation key that moves the cursor in the direction of the arrow if you keep pressing it, a move key that moves the cursor over the icon and press this key to execute the function of the icon, selected It is possible to use a key or the like that displays the number of the display device. When there are a plurality of display devices, for example, when there are four display devices, each time the SEL key is pressed, a number from 1 to 4 is sequentially selected in the display window 404.

When the SEL key is pressed, only the display device is selected, and no infrared signal is output from the remote coordinate input device. However, the display device selection signal precedes the signal output when any other key is pressed.
It is selected by the key and output according to the selection display shown in the display window 404.

As is clear from the above description of the operation, according to the present invention, the following effects can be obtained.

(1) If the distance is about 10 m,
You can operate the screen from anywhere in the room.

(2) Since the remote coordinate input device is small and lightweight, it can be carried in a pocket of work clothes. It is possible to prevent mischief and erroneous operation by an outsider when left carelessly.

(3) A plurality of display devices can also be operated selectively by utilizing the infrared method.

Recently, employee ID cards are becoming guarded. For example, by incorporating a guard reader into this remote coordinate input device, further improvement in security can be realized.

That is, by transmitting the card ID in combination with the display device selection code and the key code,
It is possible to rank the operation contents and selectively accept only the key operation within the range permitted by the card ID.
