Description

Detailed Description of the Invention [Object of the Invention] (Industrial Application Field) The present invention relates to an information display and explanation device using a computer.

(Prior art) Conventionally, in various presentations such as paper presentations at academic conferences and lectures, key points of explanations, diagrams, graphs, etc. are presented for the purpose of improving communication between presenters and listeners, and presenters use these to improve communication between presenters and listeners. Explaining while pointing. This allows the presentation to proceed effectively while appealing to the listeners' visual and auditory senses.

Incidentally, slide projectors, overhead projectors (○) (P), and the like have conventionally been used as devices to support such processes. These systems project slide films or OHP films prepared in advance by the presenter onto a screen, but it takes time and money to make the film, and the frame-by-frame feeding and instructions during the presentation are not easy to use. It was a big burden.

Recently, attempts have been made to use a computer instead of these devices and perform presentations by projecting the computer screen onto the screen.

At that time, a computer screen editor is used to create screens that correspond to conventional film. Instructions at the time of presentation are:
Using a pointing device such as a mouse, digitizer, or joystick, the mark displayed on the screen is moved to (IIH) on the screen currently being explained, and the item shown there is pointed.

By the way, in a presentation like this,
As part of the speaking procedure, instead of displaying the entire screen at once, a method is sometimes used in which a portion of the screen is displayed and the entire screen is gradually displayed as the explanation progresses. This is because visual interest can be focused on one point rather than displaying unnecessary parts at once, and the understanding of the explanation can be deepened. Conventionally, when using an OHP, such operations could be performed extremely easily by hiding unnecessary parts with cardboard or the like.

However, when attempting to perform such operations in a presentation support system using a computer, it is necessary to divide the screen in advance or create multiple screens in which the area of the displayed portion is gradually increased. There was a problem in that it took a lot of time and effort to prepare the explanation screen.

(Problem to be Solved by the Invention) As described above, in the conventional information display and explanation device using a computer, a part of the displayed screen is hidden and the entire screen is gradually displayed as the explanation progresses. The drawback was that it was difficult to use a method that would deepen the audience's understanding, making it difficult to give an effective presentation that would deepen the audience's understanding.

The present invention was made based on the above-mentioned circumstances, and an object of the present invention is to provide an information display/explanation device that can further deepen a listener's understanding.

[Structure 1 of the Invention (Means for Solving Problems) The present invention displays explanatory information accumulated in an information storage means on the screen of a display means, and displays information on the screen specified through a position specifying means. In an information display/explanation device that displays a predetermined mark at a position to improve a listener's understanding, means for generating a mask pattern for masking at least a part of explanatory information displayed on a screen; The present invention is characterized by comprising a mask range specifying means for specifying a mask range of the mask pattern generated by the mask pattern generating means.

(Operation) According to the present invention, a mask pattern is generated by the mask pattern generation means, and the mask range of the generated mask pattern can be arbitrarily designated by the mask range designation means. Therefore, even if you prepare only one explanation screen, you can mask unnecessary parts as necessary or gradually display the entire screen, making it possible to make an effective presentation. .

(Embodiment) Hereinafter, an information display and explanation device according to an embodiment of the present invention will be described with reference to the drawings.

As shown in FIG. 1, this device includes a control section 1, a storage section 2,
, a display section 3, a coordinate input section 4, a constraint information input section 5, and a mask pattern generation section 6.

The control unit 1 controls the display of explanatory screens, marks, mask patterns, etc., identifies input coordinate information and control information, and controls each unit.
(central processing unit), main memory, I10 controller, image memory, etc.

The storage section 2 serves as an information storage means for storing explanatory information M81, and uses, for example, a magnetic disk device, a floppy disk device, an optical disk device, or the like. This information for explanation is created in advance by the explainer and stored in the storage unit 2.

The display section 3 serves as a display means for displaying explanatory information, marks, mask patterns, etc. stored in the storage section 2 under the control of the computer 1, and is composed of a CRT display, a projection display, etc. . In order to provide explanations to a large number of people to be explained, it is desirable that the display device be a large-screen color display.

Further, the coordinate input section 4 serves as a position specifying means for specifying a position on the display screen of the display section 3, and also serves as a mask range specifying means for specifying a mask range. A botenting device such as a joystick is used. The coordinate information input from the coordinate input section 4 is input into the control section 1.

The control information input unit 5 specifies necessary processing such as cutting out, coloring, enlarging, and reducing the display screen, and uses, for example, a keyboard. Further, this control information input section 5 can also input control information on whether to display the screen with all or part of it masked during display. This control information is stored in the storage unit 2 in advance together with the screen information.

Further, the mask pattern generating section 6 is a section that generates a mask pattern for partially masking the explanation screen.
In response to an instruction from the control section 1, the control section 1 outputs an arbitrary mask pattern in which the top, bottom, left, right, top right, top left, bottom right, and bottom left are missing.

In the above configuration, an explanation screen with control information instructing masking of the entire screen is now displayed on the control information input section 5.
When called up via
) is displayed on the display unit 3 as a screen as shown in FIG. Mark M is displayed in superimposed form on the display screen. This mark M can be moved to any position on the screen by the explainer using the coordinate input section 4.

Further, at the top of the screen, a menu of various commands is displayed as shown in the figure. When the explainer moves the displayed mark M to the item "next page" and presses a switch (for example, a mouse switch) for the coordinate input 4, the control unit 1 executes a "next page display command". When this command is executed, the control section 1 reads out the next page of explanatory information from the storage section 2 and displays it on the display section 3. At this time, if control information for masking instructions is added to the explanatory information of the first page, a screen with the entire next page masked is displayed in the same way as above.

When the explainer moves the displayed mark M to the item "previous page" and presses the switch on the coordinate input section 4, the control section 1 executes the "previous page display command." When this command is executed, the till 1111 section 1 reads out the explanatory information of the previous page from the storage section 2 and displays it on the display section 3.

In addition, the explainer moves the displayed mark M to the position of the mask frame Q on the outer periphery of the mask pattern P, and
When the switch is pressed, the control unit 1 executes a "mask movement command" which will be described later.

The above procedure is shown in FIG. The control unit 1 receives the coordinate information from the coordinate input unit 4 and the “ON” switch.
The presence or absence of an instruction request is monitored by referring to the "OFF" information (11). If there is a next page display request (12), the next page display process is executed 13), if there is a previous page display request (14), the previous page display process is executed 15), if there is a mask movement request (16) >, execute the mask movement process 17), and in other cases execute other processes (1
8).

According to each of the above processes, the explainer gives the explanation while moving the mark M according to the flow of the explanation, and when the explanation of one page is completed, the explanation proceeds in the following order. During the explanation, you can gradually expand the display area of the masked screen or change the display area to proceed with the explanation effectively.

Next, the flow of the masking process will be explained based on FIG. 4. First, the control unit 1 controls the mask frame Q of the mask pattern P.
When it is detected that the switch of the coordinate input section 4 is pressed when the mark M is located above (FIG. 2(a)), the position of the mark M is detected and the main memory in the control section 1 is stored. (21). Next, the control unit 1 calculates which part of the mask frame Q, top, bottom, left and right, the position of the stored mark M corresponds to. The top, bottom, left and right of the mask frame Q indicate the direction in which the mask moves, and the direction in which the mask moves is determined (22).

Next, it is determined whether the switch of the coordinate input unit 4 continues to be pressed, that is, whether the mask movement request continues (23). If there is no continuation request, the process here ends, and if there is a continuation request, the indicated position of the mark M is detected again and stored (24).

Next, the previously stored position and the currently stored position are compared. If the direction of movement is up and down, only the amount of movement in the up and down direction is calculated, and the amount of movement in the left and right directions is ignored. If the left and right direction is specified, calculate only the amount of movement in the left and right direction (
25).

Once the amount of movement has been calculated, the portion of the screen that has been masked until now is read out from the storage unit 3 and displayed (26). Then, display the mask pattern P and mask frame Q in the new mask area (27)
.

The above operations are continued as long as the mask movement request continues.

As a result, a display screen as shown in FIG. 2, for example, can be obtained. In the same figure (a), position the mark M above the mask frame Q and press the switch on the coordinate input section 4. Then, in that state, move the mark M from the figure (b) → (C) →
When the mask pattern P is lowered as shown in (d), the entire mask pattern P is lowered, and an explanatory information screen for the previously hidden portion appears.

In this process, if the explanation is given using the mark M as appropriate, the explanation can be extremely effective.

Note that the present invention is not limited to the embodiments described above.

For example, as the mask pattern P, a pattern in which the upper right, upper left, etc. are missing may be used. Further, as a procedure for moving the mask pattern P, for example, the upper end portion of the mask pattern P may be moved to the position where the mark M is displayed when the switch is pressed.

Furthermore, according to the present invention, it is possible to use the same explanation method as using a conventional OHP, so by inputting the materials used in the conventional OHP using an image input device, the materials that have already been created can be used. Can be used effectively.

[Effects of the Invention] As explained above, according to the present invention, a part of the displayed screen is hidden with a mask pattern as necessary, and the entire screen is gradually displayed as the explanation progresses. It is possible to explain using methods. Therefore, it is possible to give an effective presentation that can deepen the listener's understanding.
