Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a presentation device and a presentation support method for supporting a slide presentation.

[0002]

2. Description of the Related Art Conventionally, in a method of using an information device used for a presentation purpose, for example, in PowerPoint ^{(R) of} presentation software, slides at distant positions other than the pages before and after the slide being displayed are not displayed. When it is necessary to display it, page forward while checking sequentially until the slide is found.
When returning to the original slide after the display, the presenter usually performs an operation of sequentially returning pages until the original slide is found.

Further, in order for the presenter to display slides at distant positions instead of pages located before and after the slide being displayed, for example, SPAN of conference support software.
The following methods of the presentation function of works 2000 ^(R) are also used. When performing a page-turning operation while sequentially checking until a slide at a distant position to be displayed is found, if the projector has already stored the slide, a command to display that slide is simply transmitted. When not stored, the slide to be displayed is transmitted to the projector and displayed.

[0004]

However, in the conventional device as described above, the presenter returns to the original slide after displaying another slide in a distant position while sequentially skipping the slides. In this case, it is necessary to sequentially return the slide sent earlier in the opposite direction. When the positions of the slides are separated from each other, the presenter's burden increases due to this returning work, and the time spent for the presentation as a whole also increases. In addition, communication traffic to a device such as a projector occurs each time a slide that does not need to be displayed, such as an idle feed, is repeated or a command that instructs a display is transmitted. When a device having a low communication speed is used as the communication means with the device, it takes a long time until a predetermined slide is displayed, which hinders the progress of the presentation.

The present invention has been made in consideration of the above circumstances. By omitting the display of slides which are not required to be displayed on an information terminal device such as a projector, the presenter's burden is reduced, and in addition It is an object of the present invention to provide a presentation device and a presentation support method that enable a smooth presentation.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings.

(First Embodiment) FIG. 1 shows a first embodiment of the present invention.
6 shows an example of the configuration of the terminal 11 according to the embodiment.

As shown in FIG. 1, the terminal 11 of this embodiment has a storage unit 12, a display unit 13, a communication unit 14, a measuring unit 15, a display time storage unit 16, and a time condition selection display unit 17.

The terminal 11 is used as a presentation device according to the embodiment of the present invention, and is typically a notebook computer or PDA. The terminal 11 may be any information device that allows the presenter to operate information displayed on a display device such as a projector or a CRT at the time of presentation, and is not limited to those listed here.

The storage unit 12 stores slide data. In the present embodiment, a description will be made assuming that a series of a plurality of slide data in which the order of display on a projector or the like is determined in advance is stored.

The display unit 13 reads the slide data to be displayed next from the storage unit 12 according to, for example, a page-turning instruction sent from the presenter, and the communication unit 14
Send to. Further, the measurement unit 15 is requested to measure “display time”, which is the time during which a specific slide is continuously displayed on the display device. In addition, information identifying the slide transmitted to the communication unit 14 (hereinafter referred to as slide name) is input to the display time storage unit 16.

The communication unit 14 is another information terminal device for displaying a slide, such as a projector (not shown).
To the slide data received from the display unit 13. As the communication means, for example, VGA cable, U
Wired cable such as SB cable, or 802.
A wireless LAN based on a communication standard such as 11b, Bluetooth mainly used for small-scale wireless communication, and wireless communication means such as IrDA (Infrared Data Association) using infrared rays are used.

The measuring unit 15 measures the time during which the slide is continuously displayed. As a method for measuring the “display time” from the display of a slide to the display of the next slide, for example, for a certain slide, for the next slide after the above-mentioned measurement request from the display unit 13 is made. This is a method of measuring the elapsed time until the measurement request is made. Then, this measurement result is regarded as the display time of the certain slide. The measured display time is transmitted to the display time storage unit 16.

The display time storage unit 16 stores information indicating the display time measured by the measuring unit 15 (for example, a numerical value in seconds), the slide name input by the display unit 13, and the display order (here, Information indicating the order in which the slide names are input from the display unit 13) (hereinafter, referred to as a display number) is stored. Instead of storing the information indicating the display time, a method of storing flag information indicating whether or not the measurement time is equal to or longer than a preset threshold value is also possible.

FIG. 2 shows a configuration example of the display time storage unit 16. As shown in FIG. 2, the display time storage unit 16 holds a display time table 161 having display numbers, slide names, and display times as items. Further, the display time storage unit 16 has a search unit 162 that searches the information held in the display time table 161 according to a predetermined condition.

In the method of creating the display time table 161, it is possible to store only the information about the slides displayed for a certain threshold time or longer, instead of storing the information about all the displayed slides. In this case, the display time information may be omitted from the display time table 161.

Further, the display time storage unit 16 obtains a slide to be transmitted from the display time table 161 by the search unit 162 in response to a request from the time condition selection display unit 17. With respect to the slide thus obtained, a display request is made to the display unit 13.

The time condition selection display unit 17 has a function of selecting a slide to be displayed according to the display time. For example, when there is an instruction from the presenter to turn the page for only the slides with a track record that have been displayed for a time equal to or longer than the threshold, the display is performed for a time equal to or longer than the threshold, that is, the threshold by the measuring means 15. Of the slides whose display time is equal to or more than the value, the previous most recent slide or the most recent subsequent slide as viewed from the currently displayed slide is requested to be displayed in the display time storage unit 16.

It is desirable that the presenter can freely change the setting of the threshold value indicating the time.

A method of automatically measuring the time corresponding to the threshold value is also possible. For example, the terminal 11 is provided with an operation state for measuring the threshold value, and the presenter clicks the button corresponding to the “instruction to display the slide of the next page” with the mouse in the same manner as at the time of the presentation. Several pages are continuously turned with a constant rhythm. The measuring unit 15 measures the time interval required for turning pages during that time, and divides the total display time by the total number of displayed pages. This value then becomes the average value of the time intervals required for page turning. Therefore, the threshold value described above may be determined based on this value. After setting the threshold, the presenter releases the operation state in which the threshold measurement is performed, and makes a presentation in the normal operation state.

The threshold value may be set by the presenter, automatically set, or both can be set.

FIG. 3 shows an example of a procedure from transmission of a slide to storage of information in the first embodiment. This procedure is performed for each displayed slide. First, the slide to be displayed next is transmitted from the communication unit 14 to another information terminal device (step S1). Next, the measurement unit 15 obtains the display time of the slide that has been displayed up to the present with this transmission as a trigger (step S2), and the display time storage unit 16 includes the information indicating the obtained display time, the slide name, and the display number. To store the
These pieces of information are stored (step S3).

Here, it is assumed that the display time is measured and the information is stored when each slide is first transmitted and displayed from the terminal to another information equipment terminal. If you see the same slide multiple times in your presentation,
The display time may be measured and the already stored information may be updated each time a slide is requested to be transmitted or displayed to another information device terminal. For example, a method of updating only when the display time becomes longer than the value stored so far can be considered. By doing so, it is possible to reflect not only the announcement made according to the determined flow, but also information according to the actual announcement flow such as question and answer.

The instruction to turn the page to the display unit 13 and the instruction to turn the page only for the slides displayed for a period of time equal to or longer than the time indicated by the threshold value to the time condition selection display unit 17 are given by, for example, a predetermined operation. By combining them, you can easily give them by operating the keyboard and mouse.

For example, in keyboard input, as an example of an instruction for turning pages one by one, "up arrow key" is "command to display slide of previous page (hereinafter referred to as front slide display command)" and "down arrow. The "key" can correspond to the "command for displaying the slide of the next page (hereinafter, the next slide display command)". As an example of the page turning instruction for only the slides that have been displayed for a period of time that is equal to or longer than the threshold value, press the "Shift key" and "Up arrow key" at the same time. Of the slides displayed for a period of time equal to or longer than the time indicated by (1) (hereinafter referred to as a first skip display command). That way, if the presenter presses the "up arrow key" or the "down arrow key", the slide for the previous or next page is displayed, while the presenter has the "shift key" and "up arrow key".
When is pressed at the same time, the latest slide among the slides displayed in the past for a time period equal to or longer than the threshold value can be displayed. At this time, if there is a slide that has been displayed for a period of time equal to or longer than the time indicated by the threshold value, the display of the slide that has been displayed for a time shorter than the time indicated by the threshold value is omitted.

In addition to this, for example, by simultaneously pressing the "shift key" and the "down arrow key" among "slides that have been displayed for a period of time equal to or longer than the threshold value in the order subsequent to the currently displayed slide," , The instruction to display the oldest one (hereinafter, second skip display instruction) ”. Then, the presenter may determine that this instruction has been given by pressing the “shift key” and the “down arrow key” at the same time.

In addition, for example, the presenter is the "Home key".
It is also possible to display the first displayed slide among the already displayed slides by pressing. Alternatively, by pressing the “shift key” and the “Home key” at the same time, the last displayed slide among the already displayed slides may be displayed.

Alternatively, when the "down arrow key" or the "up arrow key" is held down, page turning may be performed at time intervals corresponding to the threshold value. The slide paged at this time can also be regarded as a slide that is not displayed when the first skip display command is instructed later. To skip the display, for example, flag information indicating that the first skip display command is not displayed when the first skip display command is instructed is provided, or instead of turning the page at a time interval corresponding to the threshold, the threshold is set. The page turning may be performed at a time interval shorter than the time indicated by.

Further, for example, when the "up arrow key" is pressed n times while the "shift key" is being pressed, after omitting a slide that was displayed only for a period less than the time indicated by the threshold value, It is also possible to set to display the slide n times in the past among the slides displayed for a period of time equal to or longer than the threshold value.

Note that all or part of the above functions may be used in appropriate combination.

In the above function, key setting / setting
The operation method is an example, and other key setting / operation methods may be used. It is more preferable for the presenter to reduce the burden on the presenter by allowing the presenter to appropriately set the key setting / operation method.

Of course, the above-mentioned function is an example, and various other methods are possible.

FIG. 4 shows an example of the procedure when the presenter gives an instruction regarding page turning in the first embodiment. When the presenter gives an instruction regarding page turning (step S11), if it is a previous slide display instruction (step S12), the slide corresponding to the previous page of the slide currently displayed is transmitted to another information terminal device and displayed. (Step S13). If it is the next slide display command (step S14), the slide corresponding to the page next to the currently displayed slide is transmitted to another information terminal device and displayed (step S15). Also, the first
If it is the skip display command (step S16), of the slides displayed for a period of time equal to or longer than the threshold value before the currently displayed slide, the latest one is transmitted to another information terminal device for display. (Step S17).
If it is the second skip display command (step S18), the oldest slide among the slides that have been displayed for a period of time equal to or longer than the threshold value has already been displayed in the order subsequent to the slide currently being displayed is the other information terminal. It is transmitted to the device and displayed (step S19). If the instruction is other than that (step S
18) Perform processing according to each instruction (step S20).

Here, a description will be given with reference to a specific example showing the transition of the slide in FIG.

For example, as shown in FIG. 5A, the presenter
By the next slide display command, the presentation is performed while turning the slides a to h one by one, and when the slide h is displayed, the slides a, c, and
It is assumed that only d and h are displayed for a period longer than the time indicated by the threshold value.

In this case, the presenter uses the previous slide display command and the next slide display command as shown in FIG.
You can turn the slide one page at a time. In addition, as shown in FIG. 5B, only the slides a, c, d, and h displayed for a period of time equal to or longer than the time indicated by the threshold value by the first skip display command or the second skip display command are included in the target range. You can turn the slide one page forward or backward within the range.

Of course, the previous slide display instruction, the next slide display instruction, the first skip display instruction, and the second skip display instruction can be arbitrarily used. For example, in FIG.
As shown in (c), the first skip display command causes the slides h to be displayed all at once on the slide d, and then the previous slide display command causes the slides e, f, and
You can also turn the pages one by one like g and h and return to the slide h.

As described above, in the presentation device of this embodiment, the number of operations by the presenter is reduced by skipping the slides that were displayed for a period less than the time indicated by the threshold value without displaying them. The burden on the presenter will be reduced and the presentation will be facilitated.

(Second Embodiment) In the second embodiment, the judgment criterion is whether or not the display time of each slide is displayed for a period equal to or longer than the time indicated by the threshold value in the first embodiment. , The judgment criterion is whether or not the announcement by the presenter's voice is made.

FIG. 6 shows a configuration example of the terminal 21 according to the second embodiment of the present invention.

As shown in FIG. 6, the terminal 21 of this embodiment has a storage unit 22, a display unit 23, a communication unit 24, a detection unit 25, a presentation presence / absence storage unit 26, and a presentation condition selection display unit 27.

The terminal 21 is used as a presentation device according to the embodiment of the present invention, and is typically a notebook computer or PDA. The terminal 21 may be any information device that allows the presenter to operate information displayed on a display device such as a projector or a CRT at the time of presentation, and is not limited to those listed here.

The storage unit 22 stores slide data. In the present embodiment, a description will be made assuming that a series of a plurality of slide data in which the order of display on a projector or the like is determined in advance is stored.

The display unit 23 reads the slide data to be displayed next from the storage unit 22 in accordance with, for example, a page turning instruction sent from the presenter, and the communication unit 24
Send to. Further, the detection unit 25 is requested to detect "presence / absence of display" based on whether or not the presenter explained the specific slide by voice. In addition, the slide name is input to the presentation presence / absence storage unit 26.

The communication section 24 is another information terminal device for displaying slides, such as a projector (not shown).
To the slide data received from the display unit 23. As the communication means, for example, VGA cable, US
Wired such as B cable, or 802.1
A wireless LAN according to a communication standard such as 1b, a Bluetooth mainly used for small-scale wireless communication, a wireless communication means such as IrDA (Infrared Data Association) using infrared rays is used.

The detecting section 25 determines whether or not the presenter has added some explanation to the slide currently displayed, for example, from the input information of the microphone for inputting the voice uttered by the presenter. Either the value indicating that the announcement was made or the value indicating that the announcement was not made is output. The detected value is output to and stored in the presentation presence / absence storage unit 26.

The following method, for example, can be considered for determining whether or not each slide has been announced.

(1) Method of judging by whether or not sound is picked up by microphone etc. For example, the volume of the input voice from the microphone etc. is compared with the volume shown by a threshold value for removing noise which is set in advance. However, if the former value exceeds the latter value, it is determined that there is an announcement, and if not, it is determined that there is no announcement.

(2) Method for judging whether or not it is the volume of the presenter For example, the volume of the input voice from a microphone or the like is compared with the volume of the presenter prepared in advance, and the value of the former is the latter. It is a method of judging that there is a presentation when it is within a certain allowable range based on the value of, and judging that there is no presentation when it is not. In the case of this method, in order to determine whether the volume is the volume of the presenter, the presenter inputs the voice into the microphone at the volume at the time of the presentation before the presentation and stores the volume of the presenter in the terminal 21. I will let you.

(3) Method of judging by whether or not the character string described on the slide is read For example, the result of voice recognition of the input voice from a microphone is compared with the character string described on the slide, This is a method of determining that there is a presentation when it is determined that the character string described in the slide has been generated, and determining that there is no presentation when it is not. For example, the determination can be based on whether or not the result of voice recognition includes all or a certain ratio of the character strings described on the slide.

(4) Method of judging whether or not the presenter's voice is detected. For example, the features extracted by the voice recognition process of the input voice from the microphone and the presenter's voice prepared in advance are subjected to the voice recognition process. It is a method of comparing whether the input voice from a microphone or the like is the presenter's voice by comparing the extracted features. If it is determined that the voice of the presenter, it is determined that it has been announced, and if not, it is determined that it has not been announced. For example, the determination can be based on whether or not the similarity between the features obtained by the voice recognition processing is equal to or greater than a reference value.

In the case of this method, in order to determine whether the presenter's voice or not, the presenter inputs the voice into the microphone at the volume at the time of the presentation before the presentation, and the presenter's voice is input to the terminal 21. Remember the voice.

Of course, various methods other than the above are possible.

The presentation presence / absence storage unit 26 stores the value indicating the presence / absence of a presentation output by the detection unit 25 (hereinafter, presentation presence / absence information), the slide name input by the display unit 23, and the display order (sending order). The indicated display number is stored.

FIG. 7 shows a configuration example of the display time storage unit 26. As shown in FIG. 7, the display time storage unit 26 holds a presentation presence / absence table 261 having display numbers, slide names, and presentation presence / absence information as items. Further, the display time storage unit 26 is
The presentation presence / absence table 261 has a search unit 262 that searches for information according to a predetermined condition.

In the method of creating the presentation presence / absence table 261, instead of storing the information about all the displayed slides, it is determined that the presentation is made, that is, only the information about the slides having the announcement presence / absence information is presented. A method of storing is also possible. In this case, presentation table 2
In 61, the information regarding the presence or absence of the presentation may be omitted.

In addition, the display time storage unit 26 requests the slides to be transmitted from the presentation presence / absence table 261 by the search unit 262 in response to the request from the presentation condition selection display unit 27. The display unit 23 is requested to display the obtained slide.

The presentation condition selection display section 27 has a function of selecting a slide on which the presenter has announced by voice. For example, when there was an instruction from the presenter to turn the page only for slides that were announced, it was determined that the presenter's voice announcement was made, that is, a slide that has announcement information in the presence / absence information. Of the slides currently displayed, the previous / nearest slide or the following latest slide is requested to the presentation presence / absence storage unit 26.

FIG. 8 shows an example of a procedure from transmission of a slide to storage of information in the second embodiment. This procedure is performed for each displayed slide. First, the slide to be displayed next is transmitted from the communication unit 24 to another information terminal device (step S31). Detector 2
5 determines whether or not the slide currently being displayed has been announced (step S32), and stores the information indicating the presence or absence of the presentation, the slide name, and the display number in association with each other in the display time storage unit 26 (step S33). ).

Here, it is assumed that the presence / absence of the announcement and the storage of the information are performed when each slide is first transmitted / displayed from the terminal to another information equipment terminal. If the same slide is displayed multiple times in the presentation, the presence or absence of the presentation is detected each time the slide is requested to be sent or displayed to another information device terminal, and the already stored information is updated. You may do it. For example, there is a method of updating only when it has been stored without the announcement and the presence of the announcement is detected.

As with the first embodiment, the keyboard and the mouse are operated as the page turning instruction to the display section 23 and the page turning instruction only to the slide for which the presentation condition selection display section 27 is announced. And can be easily given.

A specific example is basically the same as that of the first embodiment.
As an example of an instruction for turning pages one by one, the "up arrow key" can correspond to the "previous slide display command" and the "down arrow key" can correspond to the "next slide display command". As an example of the page turning instruction for only the slides that have been announced, pressing the "Shift key" and "Up arrow key" at the same time is the "most slides that have been announced before the currently displayed slide. A command to display a new one (hereinafter, a third skip display command) "can be made to correspond. That way, the presenter can use the "up arrow key"
Or if you press the "down arrow key", the slide of the previous or next page is displayed, while if the presenter presses the "shift key" and the "up arrow key" at the same time,
It is possible to display the newest slide that has been announced in the past. At this time, if there is a slide that has not been announced in the past, the display of the slide is omitted.

In addition to this, for example, by pressing the "shift key" and the "down arrow key" at the same time, "of the slides already announced in the order subsequent to the slide currently being displayed,
It is also possible to correspond to an instruction to display the oldest one (hereinafter, a fourth skip display instruction). Then, the presenter can determine that this instruction is given by pressing the "shift key" and the "down arrow key" at the same time.

Further, for example, the presenter is "Home key".
It is also possible to display the first displayed slide among the already displayed slides by pressing. Alternatively, by pressing the "shift key" and the "Home key" at the same time, the last displayed slide among the slides that have already been announced by voice may be displayed.

Alternatively, when the "down arrow key" or the "up arrow key" is held down, page turning may be performed at regular time intervals. The slide page-fed at this time can also be regarded as a slide that is not displayed when the third skip display command is instructed later. In order to skip, for example, flag information indicating that the page is not displayed when the third skip display command is instructed is provided, or page turning is performed at a time interval shorter than a fixed time interval required for page turning. You can do this.

Further, for example, when the "up arrow key" is pressed n times while the "shift key" is being pressed, it is possible to display the slides that have been announced n times in the past. .

It is to be noted that all or some of the above-mentioned functions may be appropriately combined and used.

In the above function, key setting / setting
The operation method is an example, and other key setting / operation methods may be used. It is more preferable for the presenter to reduce the burden on the presenter by allowing the presenter to appropriately set the key setting / operation method.

Of course, the above-mentioned function is an example, and various other methods are possible.

FIG. 9 shows an example of the procedure when the presenter gives an instruction regarding page turning in the second embodiment. When the presenter gives an instruction regarding page turning (step S41), if it is a previous slide display instruction (step S42), the slide corresponding to the previous page of the slide currently displayed is transmitted to another information terminal device and displayed. (Step S43). If it is the next slide display command (step S44), the slide corresponding to the next page of the currently displayed slide is transmitted to another information terminal device and displayed (step S45). Also, the third
If it is the skip display command (step S46), the latest slide among the slides announced before the currently displayed slide is transmitted to another information terminal device and displayed (step S47). If it is the fourth skip display command (step S48), of the slides already announced in the order subsequent to the slide currently being displayed, the oldest one is transmitted to another information terminal device and displayed (step S48). S49). If the instruction is any other instruction (step S48), processing according to each instruction is performed (step S5).
0).

Now, description will be made with reference to a specific example showing the transition of the slide in FIG.

For example, as shown in FIG. 5A, the presenter
By the next slide display command, the presentation is performed while turning the slides a to h one by one, and when the slide h is displayed, the slides a, c, and
It is assumed that only d and h were announced.

In this case, the presenter uses the previous slide display command or the next slide display command as shown in FIG.
You can turn the slide one page at a time. In addition, as shown in FIG. 5B, only the slides a, c, d, and h which have been announced by the first skip display command and the second skip display command are set as the target range, and the slides are moved back and forth within the range. You can turn pages one by one.

Of course, the previous slide display instruction, the next slide display instruction, the first skip display instruction, and the second skip display instruction can be arbitrarily used. For example, in FIG.
As shown in (c), the first skip display command causes the slides h to be displayed all at once on the slide d, and then the previous slide display command causes the slides e, f, and
You can also turn the pages one by one like g and h and return to the slide h.

As described above, in the presentation apparatus of this embodiment, the presenter's operations are reduced by skipping slides that have not been presented without displaying them. Therefore, the presenter's burden is reduced and presentation is facilitated. Is planned.

By the way, it is possible to combine the first embodiment and the second embodiment described so far.

In the first embodiment, the slides other than the slide satisfying the first condition that the display time is displayed for a period of time equal to or longer than the threshold value are to be skipped without being displayed. In the second embodiment, the slides other than the slides that satisfy the second condition that each slide is announced by voice are to be skipped without being displayed.

At this time, for example, a slide satisfying at least one of the first condition and the second condition may be set as a display target, and a slide that does not satisfy any of these conditions may be skipped and not displayed. Alternatively, for example, only slides that satisfy both the first condition and the second condition may be displayed, and slides that do not satisfy one of the conditions may be skipped and not displayed.

Further, (1) a slide satisfying the first condition is targeted for display, (2) a slide satisfying the second condition is targeted for display, (3) the first condition and the first condition The slides that satisfy at least one of the two conditions are displayed, and (4) the slides that satisfy both the first condition and the second condition are displayed. You may make it selectable suitably.

(Third Embodiment) In the first and second embodiments, each slide is transmitted from a terminal to another information terminal device such as a projector and displayed, and a predetermined condition among the displayed slides is satisfied. Items that satisfy the conditions are targeted for skip display. In the third embodiment, one of the slides displayed on the display screen of the terminal that satisfies a predetermined condition is transmitted to another information terminal device such as a projector and displayed.

FIG. 10 shows a configuration example of the terminal 11 according to the third embodiment of the present invention.

As shown in FIG. 10, the terminal 31 of this embodiment has a storage section 32, a display section 33, a communication section 34, a measuring section 35, and a time condition transmitting section 36.

The terminal 31 is used as a presentation device according to the embodiment of the present invention, and is typically a notebook computer or PDA. The terminal 31 may be any information device that allows the presenter to operate information displayed on a display device such as a projector or a CRT at the time of presentation, and is not limited to those listed here.

The storage unit 32 stores slide data. In the present embodiment, a description will be made assuming that a series of a plurality of slide data in which the order of display on a projector or the like is determined in advance is stored.

The display unit 33 reads the slide data to be displayed next from the storage unit 32 and displays it on a display screen (not shown) of its own, for example, in response to a page turning instruction sent from the presenter. Furthermore, the measuring unit 35
A request is made to measure the "display time", which is the time during which the specific slide is continuously displayed on the display device.

When the time condition transmitting unit 36 receives a transmission request for the currently displayed slide to the information terminal device such as the projector, the communication unit 34 transmits the slide data to be transmitted.

The communication section 34 is another information terminal device for displaying slides, such as a projector (not shown).
To the slide data received from the display unit 33. As the communication means, for example, VGA cable, US
Wired such as B cable, or 802.1
A wireless LAN according to a communication standard such as 1b, a Bluetooth mainly used for small-scale wireless communication, a wireless communication means such as IrDA (Infrared Data Association) using infrared rays is used.

The measuring section 35 measures the time during which the slide is continuously displayed. As a method of measuring the “display time” from the display of a slide to the display of the next slide, for example, for a certain slide, for the next slide after the above-mentioned measurement request from the display unit 33 is made. This is a method of measuring the elapsed time until the measurement request is made. Then, this measurement result is regarded as the display time of the slide currently displayed. After the measurement, the calculated display time is transmitted to the time condition transmitting unit 36.

The time condition transmission unit 36 determines whether to send a specific slide to an information terminal device such as a projector. The time condition transmitting unit 36 has a threshold value indicating a preset time. For each slide to be displayed, the display time obtained from the measuring unit 35 is compared with this set threshold value, and the slide determined to have a display time longer than the time indicated by the threshold value is determined as the transmission target slide. to decide. Conversely, if the display time is shorter than the time indicated by the threshold,
We determine that the slide does not need to be sent.

It is desirable that the presenter can freely change the setting of this threshold value.

A method of automatically measuring the time corresponding to this threshold value is also possible. For example, the terminal 31 is provided with an operation state for measuring the threshold value, and the presenter clicks a button corresponding to the “command to display the slide of the next page” with the mouse, for example. Turn the page. The measuring unit 35 measures the time interval required for page turning during that time and divides the total display time by the total number of displayed pages. This value then becomes the average value of the time intervals required for page turning. Therefore, the threshold value described above may be determined based on this value.

The thresholds may be set by the presenter, automatically set, or both settable.

FIG. 11 shows an example of a processing procedure according to the present embodiment from the time when the slide is displayed on the display screen of the apparatus itself to the time when the slide is transmitted to another information terminal device or is ended without transmitting. That is, for example, if a slide is newly displayed on the display screen of the own terminal by the presenter's page-turning instruction (step S61), the measuring unit 35
Starts measuring the display time of the slide display (step S62).

Then, if the display of the slide on the display screen provided by itself is completed before the display time reaches the time indicated by the threshold value (steps S63 and S64), the slide is transferred to another information terminal device. Not sent. When the display of the other slide is finished because another slide is displayed on its own display screen, the measuring unit 35 starts measuring the display time of the other slide display (steps S61 and S62). ).

On the other hand, if the display time reaches the time indicated by the threshold value before the display of the slide ends (steps S63 and S64), the slide is transmitted to another information terminal device and displayed. You can

The page turning instruction to the display unit 33 can be easily given by operating, for example, a keyboard or a mouse, as in the first and second embodiments.

As a concrete example, for example, in the case of keyboard input, "up arrow key" is replaced with "previous slide display command",
The "down arrow key" can be made to correspond to the "next slide display command". Then, when the presenter presses the "up arrow key" or the "down arrow key", the slide of the previous page or the next page is displayed on the display screen of the presenter's terminal. However, at this point, the currently displayed slide is not yet transmitted to other information terminal devices. And
The slide is transmitted to another information terminal device such as a projector only when the slide is displayed on its own display screen for a period of time equal to or longer than the threshold value.

Further, the pages are continuously turned while pressing the "up arrow key" (hereinafter, "first continuous display instruction"), or the page is returned while pressing the "down arrow key" (hereinafter, " Second continuous display command ”), the slide display time on the display screen provided by itself may be set shorter than the time indicated by the threshold value.

At this time, except for the slide displayed when the key is released, the display time per slide does not reach the time indicated by the threshold value. Therefore, as long as continuous display is performed, slide data is not transmitted one by one, and unnecessary time is not consumed. For example, for a slide that does not need to be sent to the projector, by using this function, it is possible to quickly find the slide to be displayed next while checking it on the display device provided by itself. When the slide to be displayed is displayed, the slide remains displayed for the time indicated by a predetermined threshold value. Then the slide data is sent,
Displayed on a projector, etc.

Note that all or part of the above functions may be used in an appropriate combination.

In the above function, key setting / setting
The operation method is an example, and other key setting / operation methods may be used. It is more preferable for the presenter to reduce the burden on the presenter by allowing the presenter to appropriately set the key setting / operation method.

Of course, the above functions are examples, and various other methods are possible.

FIG. 12 shows an example of the procedure when the presenter gives an instruction regarding page turning in the third embodiment. If the presenter gives an instruction regarding page turning (step S71), if it is a previous slide display command (step S72), the slide corresponding to the previous page of the slide currently displayed is transmitted to another information terminal device and displayed. (Step S73). If it is a next slide display command (step S74), the slide corresponding to the next page of the slide currently displayed is transmitted to another information terminal device and displayed (step S75). If it is the first continuous display command (step S76), the display interval is shorter than the time indicated by the threshold for one slide,
The slides before the currently displayed slide are sequentially and continuously displayed on the display device provided in the slide itself (step S7).
7). If it is the second continuous display display command (step S7)
8) At a display interval shorter than the time indicated by the threshold for each slide, the slides given the order subsequent to the currently displayed slide are sequentially and continuously displayed on the display device included in the slide itself (step S79). ). If the instruction is any other instruction (step S80), processing according to each instruction is performed (step S80).

The presenter appropriately uses the above instructions,
By displaying each slide on the display screen of the terminal for a period of time equal to or longer than the time indicated by the threshold value, it is possible to transmit and display the specific slide to another information terminal device.

As described above, in the presentation device of this embodiment, the data of the slide that has been displayed on the display screen of the terminal itself for a period shorter than the time indicated by the threshold value is transmitted to another information terminal device. do not do. Therefore, the amount of communication data can be reduced, and the time until one slide is displayed can be shortened. Therefore, unnecessary time at the time of presentation can be reduced and the presentation can be smoothly performed as a whole.
