A switch 14B for controlling light beam irradiation is provided on a side surface of the remote control device 1.

FIG. 3 shows how the remote control device is used. The remote controller 1 is carried by the speaker, and is operated by the speaker as the lecture progresses. The operation information is transmitted by wireless communication from the remote control device 1 and received by the wireless device 2. The driver program 32B of the personal computer 3 converts the operation information received by the wireless device 2 into a corresponding operation input,
In A, data file display control is performed based on the operation input. As a result, a screen page corresponding to the remote control operation of the speaker is displayed on the screen 5 via the projector 4. The spot 16 appears on the screen 5 by irradiating the light beam 15 from the remote control device 1. Thereby, the display content can be instructed without using a laser pen or the like separately.

The remote controller 1 is not limited to the shape shown in FIG. 2. For example, the remote controller 1 may be formed in a pen shape, and the buttons may be arranged on the body of the remote controller so that a light beam is emitted from the tip. . Also, for the wireless device 2,
The case where the external device is connected to the personal computer 3 has been described as an example.
It is also conceivable to mount it on a PC card and mount it inside the personal computer 3 as used in an AN or the like.

Next, the operation of the presentation system shown in FIG. 1 will be described. When the PC starts up, the storage unit 3
4 is automatically read from the CPU 4 and executed by the CPU 32. The OS has a function of exchanging various data with each unit connected to the CPU 32. For example, key input data from the operation input unit 38 is transferred to the AP 32A in the form of an input message. This allows AP32
In A, it is recognized that a predetermined key operation has been performed on the operation input unit 38, and a process corresponding to the operation is executed. In the present system, the display information is switched by the operation of the remote control device 1 by transferring the operation information from the remote control device 1 to the presentation AP 32B.

FIG. 3 shows an AP 32 for presentation.
4 shows a flowchart of a display control operation by A. Here, A based on an operation from the operation input unit 38 of the personal computer 3
The display control operation of P32A will be described. AP32B
Is read from the storage unit 34 to the memory 35 by the OS in response to an operation from the operation input unit 38, and is executed by the CPU 32. First, a data file specified at the time of startup or a data file specified by an operation after startup is read from the storage unit 34 (step 100). In this data file, display data composed of characters and images is divided for each screen page. Here, the display data described in the first screen page is first read from the data file, and the display unit I / F 33 is displayed. The data is output to the projector 4 via the CPU 4 (step 101), and waits for an operation input (step 102).

If there is a right or down arrow key input from the operation input section 38 (step 102: YE
S) Only when there is a next screen page in the data file (step 104: YES), the display data of the next screen page is read and displayed (step 105), and the process returns to step 102. If there is a left or up arrow key input from the operation input unit 38 (step 106: YES),
Only when there is a previous screen page in the data file (step 107: YES), the display data of the previous screen page is read and displayed (step 108), and step 1 is executed.
Return to 02.

If there is an ESC (escape) key input from the operation input unit 38 (step 109: YE
S), the display control operation of the selected data file ends. Thus, in the AP 32A, the display control is performed based on the operation from the operation input unit 38 of the personal computer 3.

FIG. 4 shows a flowchart of the operation information conversion operation by the driver program 32B. The driver program 32B is stored in the storage unit 34 by the OS as necessary.
Is read out to the memory 35 and executed by the CPU 32. First, the communication I / F 31 waits for reception of operation information from the wireless device 2 (step 120). Communication I / F
In step 31, the operation information is fetched in response to the reception of the operation information (step 121). Then, referring to the operation definition table, an operation input corresponding to the operation information from the remote control device 1 is obtained (step 122), and output as an operation input used in the AP 32A (step 123).

Thus, the driver program 32B
The operation input output from the PC 3 is the operation input unit 3 of the personal computer 3.
In the same manner as the operation input from No. 8, it is transferred to the AP 32A, analyzed by the above-described display control operation (see FIG. 3), and the corresponding display control is performed. Here, the case where the display control operation is performed in response to the key operation in the AP 32A has been described, but there is a case where the display control operation is performed using a pointer device such as a mouse. In such a case, the input by the trackball 13H is transmitted from the remote control device 1 according to predetermined operation information, and the input is transmitted to the driver program 32.
B may be converted into an operation input from the pointer device.

FIG. 5 shows a configuration example of the operation definition table. Here, for example, up arrow button 1 of remote control device 1
3D (see FIG. 2) is associated with the “up arrow key” on the keyboard of the operation input unit 38 of the personal computer. In this case, as the operation input to be assigned to each button of the remote control device 1, as described above, only one arbitrary key of the keyboard may be assigned, or a plurality of key operations may be assigned. For example, a series of key operations for selecting the data file A as the data file to be displayed and output on the AP 32A, such as the F2 button, may be assigned. Thereby, a presentation can be made by switching a plurality of data files. By assigning a plurality of key operations to one button in this manner, relatively sophisticated display control including a plurality of key operations can be remotely controlled by a simple operation of the remote control device 1.

FIG. 6 shows a flowchart of the operation definition table registration operation. By operating the operation input unit 38 of the personal computer 3, the driver program 32B starts an operation definition table registration operation. First, a registration screen as shown in FIG. 8 is displayed on the screen display unit 37 of the personal computer 3 (Step 130), and the operation waits for an operation input (Step 13).
1). The registration screen has an input area for each button of the remote control device. Here, the operation input unit 3
If there is a character input from the keyboard 8 (step 132: YES), the key information of the character input is sequentially added to the currently selected input area (step 13).
3) Return to step 131. If the TAB key has been input (step 134: YES), the input area is switched based on a predetermined order (step 135), and the process returns to step 131. Thus, any key operation can be input to the input area of any button.

If the cancel button on the registration screen is pressed (step 136: YES), the key operation input to each input area is regarded as invalid, and the processing is terminated without redefining. If the registration button on the registration screen is pressed (step 137: YES), the key operation input to each input area is updated and registered in the operation definition table in association with each button (step 138). The process ends. In addition, a predetermined operation input may be fixedly assigned to each button of the remote control device 1. However, since it can be arbitrarily defined in this way, the specification of the display control operation of the AP 32A, the usability of the user, etc. Can respond flexibly. In particular, the driver program 32B converts the operation information from the remote control device 1 into an operation input for changing the display screen page on the AP 32A and an operation input for changing the display data file.
Display control intended by the speaker can be easily realized by remote control operation.

In the above description, the display device 6 including the projector 4 and the screen 5 has been described as an example, but the present invention is not limited to this. For example, even when a large-screen display device using a plasma display or an LED display is used, it can be applied in the same manner as described above, and the same operation and effect can be obtained. The driver program 32B may be recorded on the recording medium 7 and sold / distributed together with the wireless device 2, or the recording medium 7 may be sold / distributed alone.
May be distributed.
