Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a presentation device used for presenting while showing a display screen of display means controlled by a computer to an audience.

[0002]

2. Description of the Related Art At the time of a research presentation or a lecture, it is often done to give a presentation while showing a display screen of a display means controlled by a computer to an audience (hereinafter referred to as "presentation"). In this case, the presenter may point a part of the display means with a pointing stick in order to designate a portion of the display screen that requires a particular explanation.

Further, when the display means is constructed so as to project an image from a projector on a screen, a point on the screen is illuminated with, for example, arrow-shaped light to indicate the explanation place. May be done.

In particular, when giving a presentation using an overhead projector (hereinafter referred to as "OHP"), there are cases where the presentation is performed while writing on the original surface of the OHP with a marker pen.

Further, the figure presenting device such as a CAD device or a computer graphic device is activated to show the display screen of the device to the audience, and the presenter additionally writes, changes, or deletes it with coordinate input means such as a mouse, digitizer or tablet. In some cases, explanations will be given while performing the above.

When the mouse or digitizer is used, the presenter can simply move the position of the mouse or the like without writing or the like to move a mouse pointer or other mark, such as an arrow-shaped mark, on the display screen. There is also a case where the explanation location is instructed by.

[0007]

Among the above-mentioned conventional techniques, the use of the pointing rod has a problem that it is difficult to point a portion of the display screen far from the presenter. There is also a problem that a part of the display screen is hidden by the indicator stick or the body of the presenter, making it difficult for the audience to see. Further, there is a problem that it is difficult to speak because the presenter is forced to give an unreasonable posture by pointing a part of the screen with the pointing stick.

In the case of the conventional example in which light is applied to the screen, the portion indicated by the light may be small and difficult to see. In addition, there is a problem in that it is difficult to tell the audience exactly where the explanation is because the place to point is not stable.

In the conventional example in which writing is performed on the original surface of the OHP with a marker pen, there is a problem that the presenter is forced to perform writing and erasing operations, so that he cannot concentrate on his presentation and explanation. Also, the presenter's hand becomes dirty with the ink of the marker pen. Further, since the document surface on the OHP is illuminated by strong light, staring for a long time has an adverse effect on the presenter's eyes such as eye fatigue.

In the conventional example in which the presenter makes the display screen at that time visible to the audience while the presenter performs the work such as writing, changing and deleting by the coordinate input means by the coordinate input means, at first glance, the above problem is solved. It seems to be solved. However, if only the writing work is continued, the display screen will be filled with the graphics written at the time of presentation, making it difficult for the audience to recognize what the original screen was like. In addition, it is difficult to know which one was input immediately before, and there is a risk that the current explanation is lost. Therefore, it is not as easy as instructing with a pointing stick, because the presenter is forced to work such as deleting and writing such as erasing and writing and then writing and erasing the figure input at the time of presentation. There's a problem. Even if a dedicated operator other than the presenter is provided to assist the presenter in order to solve this problem, it is difficult for the two to come together, so it cannot be expected to be as easy as a pointing stick.

In the conventional example in which a mark such as a mouse pointer is moved by changing the pointing position without writing with a mouse or the like, only a point on the display screen is pointed, and a certain spread is made. I can't tell what range I have. When the mouse or the like is moved to draw a circle, for example, to enclose a wide area, the audience is forced to gaze at the display screen in the meantime.

The inventor of the present invention uses a device having a simple graphic creation function such as inputting a freehand curve and automatically deletes the previous graphic when the second and subsequent inputs are made. I thought that I could solve the above problems. An object of the present invention is to use a computer-based graphic creation device,
It is to realize a presentation device capable of pointing to an explanation location with the convenience of a pointing stick.

[0013]

In order to achieve the above object, a presentation apparatus according to the present invention has a coordinate input means for inputting coordinate values, a display means for displaying a display screen, and a display for the display means. A presentation device having display content data storage means for storing content data, and display content changing means for changing the content of the display content data stored in the display content data storage means according to the coordinate information input by the coordinate input means. In, a marker handwriting data storage means for taking in a series of continuous coordinate inputs from the coordinate input means, and a marker handwriting for taking a series of continuous coordinate inputs from the coordinate input means into the marker handwriting data storage means as handwriting data. The writing means and the marker handwriting writing by the marker handwriting writing means are interlocked with and previously input. The marker handwriting erasing means for erasing a set of continuous coordinate input, in which the contents of the marker handwriting data storage means was to have a display content synthesizing means for synthesizing the contents of the display content data storage means.

Further, the coordinate input surface of the coordinate input means has a marker function selection area and a drawing area which are exclusively provided, and when there is a coordinate input in the marker function selection area, the marker handwriting writing means and the marker It is effective that the handwriting erasing means and the display content synthesizing means are executed so that the coordinate input in the drawing area is stored in the marker handwriting data storage means.

Further, in addition to the display means, another display means is provided as a flat plate display means in a stacked arrangement with respect to the coordinate input surface of the coordinate input means, and the position of the coordinate indicator coincides with the display position. It is preferable to do so.

[0016]

When the presentation device configured as described above is activated, the handwriting (freehand figure) drawn by the presenter using the coordinate input means is displayed on the display screen without modifying the original display content. . Also, if there is a series of coordinate input, the previous handwriting is automatically deleted.

By providing a marker function selection area in the menu area of the coordinate input means, it functions as an independent function separate from other display content changing functions (enlargement, reduction, zoom, scroll, page feed, etc.). become.

Further, by arranging another display means on the coordinate detection device in addition to the display means for the presenter to show to the audience, the instruction of the explanation place can be made more accurate while confirming the instruction content at hand. You can do it.

[0019]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view showing the external appearance of this apparatus. The present apparatus roughly comprises a computer 10, coordinate input means 40 as an input device thereof, and display means 50 as an output device.

The coordinate input means 40 is a so-called pointing device. It may be a device such as a mouse or a joystick that inputs relative coordinates, or an absolute coordinate input device called a digitizer or tablet. However, in an embodiment in which flat plate display means are laminated and arranged as described later, it is necessary to use absolute coordinate input means such as a digitizer or a tablet. This is because, in that case, it is necessary that the designated position and the display position always match. It should be noted that such a pointing device is indispensable to the present apparatus, but it goes without saying that an embodiment in which a keyboard is also used as an auxiliary input device is also possible.

Since the display means 50 is for showing to the audience, it is preferably a large screen display means. Although the projector type shown in FIG. 1 projects from the front side, the CR
It goes without saying that it may be a large screen of the T device, or may be display means based on another principle.

FIG. 2 is a block diagram showing the equipment configuration of this apparatus. As described above, the present apparatus has the computer 10, but the central processing unit 1 (C
PU). Needless to say, the main storage means 3 is connected to the bus 2 connected to the central processing means 1. The main storage means 3 stores programs such as a display content changing program and a marker program, as well as display content data and marker handwriting data. Therefore, as a part of the main storage means for convenience, the display content change program storage means 31, the marker program storage means 32, the display content data storage means 3
3. It is assumed that there is a marker handwriting data storage means 34.
These programs and data are usually stored as files in a secondary storage means (not shown in FIG. 2) such as a floppy disk or a hard disk, and are appropriately read as needed.

The coordinate input means 40 is connected to the bus 2 via a necessary interface (not shown in FIG. 2) such as a serial interface. As described above, the coordinate input means 40 may be one that inputs relative coordinates, but in FIG. 2, a tablet for inputting absolute coordinates is drawn. The coordinate input means control means 41 is a so-called control section of the coordinate input means 40. A coordinate detection surface is provided on the tablet 42. Regardless of the principle of coordinate detection, when one point on the tablet 42 is pointed by the position pointing device 43, the coordinate input means control means 41 performs processing such as coordinate value calculation and the obtained coordinate data is transferred to the bus 2. To the central processing means 1.

On the coordinate detection surface of the tablet 42, a display content change menu area 44, a marker function selection area 45, a drawing area
46 is preferably provided. Smooth transition between the input of freehand graphics (hereinafter referred to as "markers") for instructing explanations at the time of presentation and other display content change processing (enlargement, reduction, zooming, scrolling, page feed, etc.) To do this. Display content change menu area
The menu area including the 44 and the marker function selection area 45 can be provided by printing on the surface of the housing of the tablet 42 or by placing the menu sheet thereon, but in the embodiment in which the flat display means are stacked and arranged. In this case, the menu area can be displayed by the display means.
The former is advantageous when it is desired to not show the menu to the audience, and the latter is advantageous when the presentation or the like is intended to inform the audience of the computer operation itself. .

The position indicator 43 is shown in FIG. 2 as a writing instrument-like shape, that is, a so-called stylus pen, but it has another shape, for example, a box shape usually called a cursor. May be. Needless to say, the stylus pen is advantageous when the presenter wants to draw handwritten characters or symbols using the marker function in a presentation.

The display means 50 is connected to the bus 2 via the display means control means 51 and a necessary interface (not shown). The video RAM 52 is a memory for holding the display content data of the screen currently displayed by the display means 50. The display means control means 51 continues to display the content held in the video RAM 52 on the display means 50 until a new display signal is sent from the central processing means 1.

Next, the operation of this apparatus will be described with reference to FIGS.
Will be described with reference to.

FIG. 3 shows an example of a flow chart showing the flow of basic processing of this apparatus, and FIG. 4 is a flow chart showing the flow of marker processing. As described above, an embodiment in which a keyboard is used as an auxiliary is also possible, and in that case, the menu selection can be made by inputting a command from the keyboard, for example. A case where the display content is changed or the marker function is selected by pointing is described.

When coordinates are input from the tablet, FIG.
The process starts at Step 1 of. First, it is determined whether or not the input coordinate value belongs to the display content change menu area (Step 2). If it is in the display content change menu area, display content change processing is started (Step).
3). The display content changing process is performed according to the display content changing program stored in the display content changing program storage means 31 shown in FIG. 2, and is the same display as that used in the known computer aided design (CAD). Performs processing such as screen scaling, zooming, scrolling, and page turning. When the processing is completed, the process returns (Step
p6). Then, wait for coordinates input from the tablet (S
step1).

If No in Step 2, it is determined whether or not it is the marker function selection area (Step 4). If it is within the area, the marker processing shown in FIG. 4 is started (Step).
5). Otherwise, return (Step 6, Step)
1).

When the marker processing shown in FIG. 4 is entered (Step
p10), and waits for the next coordinate input (Step 11). When the coordinates are input, it is first determined whether or not it is the display content change menu area (Step 12). This is to provide a procedure for exiting the marker processing (Step 13).

If it is not in the display content change menu area, it is judged whether or not it is a drawing area (Step 14). If it is not within the area, the process returns and waits for coordinate input (Step 11).
If it is within the drawing area, it is determined whether or not the immediately preceding coordinate input was also in the drawing area (Step 15). This is because the marker handwriting data is erased depending on whether or not it is the beginning of a series of coordinate inputs and as a result.

If it is not the beginning of a series of coordinate input, that is, if the previous coordinate is also the drawing area in Step 15, the coordinate data is written in the marker handwriting data storage means 34 (Step 16). Then, the contents of the marker handwriting data storage means 34 are combined with the contents of the display content data storage means 33 (Step 18). As a result, the freehand figure (marker) drawn by the presenter with the position indicator is displayed on the display means 50. In order to display the display content on the display means 50, the content of the display content data storage means 33 is transferred to the video RAM 52 via the display means control means 51 periodically or at a certain timing. Needless to say, this processing is omitted in FIGS. 3 and 4.

If it is the beginning of a series of coordinate input, that is, if the drawing area is not present immediately before in Step 15, the contents of the marker handwriting data storage means 34 are erased (Step).
p17). Then, the content of the marker handwriting data storage means 34 is combined with the content of the display content data storage means 33 (Step
p18). As a result, when the presenter starts to draw the marker, the previous marker is automatically deleted.

In this way, when performing the marker processing, the presenter can point to a part of the display screen one after another, in the same manner as pointing to the explanation point with the pointing stick. In order to get out of this marker processing, the display contents change menu area is instructed by the position indicator as touched previously (Step 12). At that time, the process proceeds from Step 13 to Step 3 and the above-described display change processing is performed. At that time, an embodiment in which the marker handwriting data is erased to perform processing such as enlargement / reduction or page feed is also possible, but the marker handwriting data is not erased and the marker is also enlarged / reduced, zoomed, scrolled, or the like. Embodiments to be targeted are also possible.

It is needless to say that the above-mentioned flow chart shows an example of the flow for realizing the marker function of the present apparatus and is not limited to this. According to the marker program stored in the marker program storage means 32 shown in FIG. 2, the central processing means 1 constitutes a marker handwriting writing means, a marker handwriting erasing means, and a display content synthesizing means, and the marker handwriting erasing is performed in a continuous sequence. This is because the present invention is characterized in that it is configured so that it is automatically performed in conjunction with the input of the coordinate.

[0038]

According to the present invention, the marker handwriting data storage means is provided as a storage means independent of the display content data storage means and the display content synthesizing means is provided, so that the marker display can be performed without changing the original display screen. Display is now possible.

Since the marker is erased in synchronism with the writing of the marker, the marker can be displayed easily with the same feeling as using the pointing stick without performing a complicated operation.

Since the marker handwriting data storage means holds the handwriting of the marker until the next input, the audience can easily grasp where the object currently being described is. And unlike the pointer, the presenter does not have to keep holding the point while talking, so he can concentrate on the talk.

Since the input is possible by operating the coordinate input means at hand, the presenter can display the marker with a few movements, no matter how large the display screen shown to the audience is. Also, because less physical movement is required,
Easy to speak.

Unlike direct pointing the display screen with the pointing stick, no blind spot is created for the audience.

Since the display of the marker can be made a color that is noticeable to the audience, it is possible to clearly inform the audience where the explanation is.

Since the marker is displayed by the coordinate input means, ink is not used, so that a clean presentation device can be provided which is free from stains.

Unlike the OHP document surface, the coordinate input surface of the coordinate input means does not emit strong light, and therefore the presenter's eyes are not tired.

Since the operation of this device is simple, it is possible to make a presentation while operating the presenter by himself without providing an operator other than the presenter.

In particular, since the menu area is provided on the coordinate input surface and the menu is selected by operating the position indicator, it is not necessary to use a keyboard or the like as an auxiliary, and the operability is improved.

Further, by providing the coordinate input means with a display means different from what is shown to the audience and arranging them in layers, the presenter can operate while looking at the hand, so it is necessary to direct the line of sight to the display screen seen by the audience. Is reduced. This benefits the presenter in that it allows them to focus on other information, such as audience reaction.
