Description

  The present invention relates to a presentation apparatus and a presentation support method for supporting a slide presentation.

  Conventionally, in a method of using information equipment used for presentation purposes, for example, PowerPoint (registered trademark) of presentation software needs to display a slide at a distant position that is not a page positioned before and after the slide being displayed. In some cases, pages are turned while sequentially checking 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.

  In addition, for example, the presentation function of SPANworks 2000 (registered trademark) of conference support software has the following in order to display a slide at a position apart from a page that is not positioned forward or backward with respect to the slide being displayed by the presenter. Such a method is also performed. If the projector has already memorized the slide when performing an operation of turning pages while sequentially confirming until a slide at a distant position to be displayed is found, a command for simply displaying the slide is transmitted. When not stored, the slide to be displayed is transmitted to the projector and displayed.

  However, in the conventional device as described above, when the presenter returns to the original slide again after displaying another slide at a distant position while sequentially skipping the slide, the slide sent earlier is again displayed. It is necessary to sequentially return in the reverse direction. If the positions of the slides are far from each other, the burden on the presenter increases due to the returning operation, and the time spent for the presentation as a whole also increases. Further, every time a slide that does not need to be displayed such as skipping is repeated or a command for instructing display is transmitted, communication traffic to a device such as a projector is generated. When a device with a low communication speed is used as the communication means with the device, it takes a long time to display a predetermined slide, which hinders the progress of the presentation.

  The present invention has been made in consideration of the above circumstances, and by reducing the display of slides that do not need to be displayed on an information terminal device such as a projector, the burden on the presenter is reduced, and in addition, smooth presentations are made. It is an object of the present invention to provide a presentation apparatus and a presentation support method that can be performed in a simple manner.

  According to the present invention, in a presentation device that transmits data of a plurality of slides to an information terminal device that displays a slide, means for storing data of the plurality of slides, and the data of the slide to the information terminal device in a predetermined order Means for transmitting, means for obtaining a display time for each of the slides transmitted to the information terminal device to be displayed on the information terminal device, and at least for each of the slides transmitted to the information terminal device Storage means for storing information indicating the order in which data is transmitted to the information terminal device and information indicating the display time obtained for the slide in association with each other, and when receiving a specific command, the storage Based on the information stored in the means, it has information indicating a display time that is equal to or greater than the time indicated by a predetermined threshold. Ride one selected, characterized in that a control means for transmitting the data of the selected slide to the information terminal device.

  According to the present invention, when a presenter makes a presentation, it is possible to display only a slide previously selected from slides displayed for a time indicated by a predetermined threshold. The presenter does not need to perform an operation of skipping a slide that is deemed unnecessary for the presentation or returning the slide that has been skipped, and can display the slide that the audience wants to show to the audience with fewer operations.

  Further, the present invention provides a presentation apparatus that transmits data of a plurality of slides to an information terminal device that displays slides, means for storing data of a plurality of slides, and the information terminals in a predetermined order. Means for transmitting to the device, means for determining whether or not a presenter has made a presentation by voice for each of the slides transmitted to the information terminal device, and for each of the slides transmitted to the information terminal device, Storage means for storing at least information indicating the order in which the data of the slide is transmitted to the information terminal device and information indicating whether or not the slide has been announced, and a specific command; If received, the slide determined to have been announced based on the information stored in the storage means. One selected, characterized by comprising a control means for transmitting the data of the selected slide to the information terminal device.

  According to the present invention, it is possible to display only selected slides that have been determined to have been announced by the presenter's voice in the past. The presenter does not need to perform an operation of skipping a slide that is deemed unnecessary for the presentation or returning the slide that has been skipped, and can display the slide that the audience wants to show to the audience with fewer operations.

  The present invention also provides means for storing data of a plurality of slides and means for displaying one of the slides on a display screen in a presentation apparatus that transmits data of the plurality of slides to an information terminal device that displays the slides. Switching means for switching the slide displayed on the display screen to the next slide when receiving a specific command, means for obtaining a display time during which the slide is continuously displayed on the display screen, The slide displayed on the display screen includes a transmission unit that transmits data of the slide to the information terminal device when the display time reaches a time indicated by a predetermined threshold value. It is characterized by that.

  According to the present invention, a slide that has been displayed for a time shorter than the time indicated by the predetermined threshold when continuous page turning is performed on the display screen of the presentation device is not transmitted to the information terminal device. Then, only slides displayed for a time equal to or greater than a predetermined threshold, that is, slides that are considered to be used for presentation are transmitted to the information terminal device. Therefore, the amount of communication data is reduced, and the time taken to display a desired slide can be shortened.

  Also, the presenter can display only the desired slides by displaying only the slides desired to be shown to the audience on the display screen of the presentation device, for example, by a page turning operation, for a period longer than the time indicated by the predetermined threshold. Can be shown to the audience.

  The present invention relating to the apparatus is also established as an invention relating to a method, and the present invention relating to a method is also established as an invention relating to an apparatus. Further, the present invention relating to an apparatus or a method has a function for causing a computer to execute a procedure corresponding to the invention (or for causing a computer to function as a means corresponding to the invention, or for a computer to have a function corresponding to the invention. It is also established as a program (for realizing) and also as a computer-readable recording medium on which the program is recorded.

  ADVANTAGE OF THE INVENTION According to this invention, the presentation apparatus which can reduce a burden of a presenter and can make a presentation smoothly by not displaying the slide which does not need to be displayed can be provided.

  Hereinafter, embodiments of the invention will be described with reference to the drawings.

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

  As illustrated in FIG. 1, the terminal 11 according to the present embodiment includes a storage unit 12, a display unit 13, a communication unit 14, a measurement unit 15, a display time storage unit 16, and a time condition selection display unit 17.

  The terminal 11 is used as a presentation apparatus according to the embodiment of the present invention, and a laptop computer or a PDA is typical, for example. 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 given assuming that a series of a plurality of slide data whose order of display on a projector or the like is determined in advance is stored.

  The display unit 13 reads out slide data to be displayed next from the storage unit 12 and transmits it to the communication unit 14 in accordance with, for example, a page turning instruction sent from the presenter. 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 for identifying the slide transmitted to the communication unit 14 (hereinafter referred to as a slide name) is input to the display time storage unit 16.

  The communication unit 14 transmits the slide data received from the display unit 13 to another information terminal device that displays the slide, such as a projector (not shown). As a communication means, for example, a wired cable such as a VGA cable, a USB cable, or a wireless LAN based on a communication standard such as 802.11b, Bluetooth mainly used for small-scale wireless communication, IrDA (Infrared Data using infrared rays). Wireless communication means such as Association) is used.

  The measuring unit 15 measures the time during which the slide has been displayed. As a method of measuring the “display time” from when a slide is displayed to when the next slide is displayed, for example, with respect to a certain slide, after the measurement request from the display unit 13 is received, the next slide is displayed. This is a method of measuring the elapsed time until there is a measurement request. 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 includes information indicating the display time measured by the measurement unit 15 (for example, a numerical value in units of seconds), a slide name input by the display unit 13, and a display order (here, the display unit 13). Information indicating the order in which the slide names are input from (hereinafter referred to as display numbers). Instead of storing information indicating the display time, a method of storing flag information indicating whether or not the measurement time is equal to or greater 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 whose items are display numbers, slide names, and display times. The display time storage unit 16 has a search unit 162 that searches information stored in the display time table 161 according to a predetermined condition.

  Note that, in the method of creating the display time table 161, instead of storing information on all displayed slides, only information on slides displayed for a certain threshold time or longer can be stored. In this case, display time information may be omitted from the display time table 161.

  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. The display unit 13 is requested to display the slide thus obtained.

  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 only for a slide with a track record that has been displayed for a time longer than a threshold value, the time is displayed for a time longer than a threshold value, that is, the threshold is measured by the measuring means 15 Of the slides whose display time is equal to or greater than the value, a request is made to display to the display time storage unit 16 the previous slide that was previously viewed from the slide that is currently displayed, or the latest slide that follows.

  It is desirable that the threshold value indicating this time can be freely set and changed by the presenter inputting it.

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

  Further, 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 slide transmission to information storage 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 now with this transmission as a trigger (step S2), and displays information indicating the obtained display time, the slide name, and the display number in the display time storage unit 16. Are stored in association with each other, and these pieces of information are stored (step S3).

  Here, the measurement of the display time and the storage of the information are performed when each slide is first transmitted / displayed from the terminal to another information device terminal. When the same slide is displayed multiple times during the presentation, the display time is measured and the information already stored is updated each time a slide is sent to another information device terminal or a display request is made. You may make it perform. For example, a method of updating only when the display time becomes longer than a value stored so far can be considered. In this way, it is possible to reflect not only announcements made according to a fixed flow but also information according to the flow of actual presentations such as questions and answers.

  For example, a page turning instruction for the display unit 13 or a page turning instruction for only a slide displayed for a period of time equal to or greater than the time indicated by the threshold value for the time condition selection display unit 17 may be performed by combining predetermined operations. Can be given easily by operating the keyboard and mouse.

  For example, in the case of keyboard input, as an example of an instruction for turning pages one by one, “up arrow key” is set to “command to display slide of previous page (hereinafter referred to as previous slide display command)” and “down arrow key”. Each can correspond to a “command to display the slide of the next page (hereinafter referred to as a next slide display command)”. As an example of page turning instructions for only slides that have been displayed for a period of time longer than the threshold value, press the “Shift key” and “Up arrow key” at the same time. Can be made to correspond to a command for displaying the newest slide among the slides displayed for a period longer than the time indicated by (hereinafter referred to as a first skip display command). Then, when the presenter presses the “Up Arrow Key” or “Down Arrow Key”, the slide of the previous or next page is displayed, while the presenter displays “Shift Key” and “Up Arrow Key”. When the buttons are pressed at the same time, it is possible to display the newest slide among the slides displayed for a period of time equal to or longer than the time indicated by the threshold value in the past. At this time, if there is a slide displayed for a period longer than the time indicated by the threshold, the display of the slide that has been displayed only for a time shorter than the time indicated by the threshold is omitted.

  In addition to this, for example, when the “shift key” and “down arrow key” are simultaneously pressed, “the first slide among the slides that have been displayed for a period longer than the time indicated by the threshold in the order after the slide that is currently displayed. It is also possible to correspond to an instruction for displaying an old one (hereinafter referred to as a second skip display instruction). In this case, it is only necessary to determine that this instruction is given by the presenter pressing the “shift key” and the “down arrow key” at the same time.

  Further, for example, when the presenter presses the “Home key”, the slide that is displayed first among the already displayed slides can be displayed. 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.

  In addition, when the “down arrow key” or the “up arrow key” is held down, the page may be turned at a time interval corresponding to the threshold value. The slide that has been paged at this time can also be regarded as a slide that is not displayed when the first skip display command is instructed later. In order to skip the display, for example, instead of providing flag information indicating that the first skip display command is not displayed or turning the page at a time interval corresponding to the threshold value, a threshold value is used. The page turning may be performed at a time interval shorter than the time indicated by.

  Further, for example, when the “shift key” is pressed and the “up arrow key” is pressed n times, the threshold value after omitting a slide that is displayed for a period less than the time indicated by the threshold value is omitted. It is also possible to set to display the previous n times of slides displayed for a period longer than the time indicated by.

  In addition, you may use combining all or one part of said function suitably.

  In the above function, the key setting / operation method is an example, and other key setting / operation methods may be used. Further, it is more preferable for the presenter to reduce the burden on the presenter if the presenter can appropriately set the key setting / operation method.

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

  FIG. 4 shows an example of a procedure when an instruction regarding page turning is given from the presenter in the first embodiment. When an instruction regarding page turning is given from the presenter (step S11), if it is a previous slide display command (step S12), the slide corresponding to the previous page of the currently displayed slide is transmitted to other information terminal devices for display. (Step S13). If it is a next slide display command (step S14), the slide corresponding to the next page of the currently displayed slide is transmitted to other information terminal devices and displayed (step S15). If it is the first skip display command (step S16), the newest slide among the slides displayed for a period of time longer than the time indicated by the threshold before the currently displayed slide is sent to another information terminal device. Transmit and display (step S17). If it is the second skip display command (step S18), the oldest slide among the slides displayed for a period of time equal to or greater than the time indicated by the threshold in the subsequent order from the slide currently being displayed is the other information terminal. The data is transmitted to the device and displayed (step S19). If it is an instruction other than that (step S18), processing corresponding to each instruction is performed (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. 5 (a), the presenter gives a presentation while turning the slides a to h one by one by the next slide display command, and when the slide h is displayed, the slides a and c are displayed. , D, and h are only displayed for a period longer than the time indicated by the threshold value.

  In this case, as shown in FIG. 5A, the presenter can turn the slide one page forward and backward by a previous slide display command and a next slide display command. Further, as shown in FIG. 5B, only the slides a, c, d, and h that are displayed for a period longer than the time indicated by the threshold by the first skip display command or the second skip display command are the target range. As a result, it is possible to turn the slide one page forward and backward within the range.

  Of course, the previous slide display command, the next slide display command, the first skip display command, and the second skip display command can be arbitrarily used. For example, as shown in FIG. 5C, after the first skip display command causes the slide d to be skipped from the slide h at a stroke, the slides e, f, g, h are displayed by the previous slide display command. Thus, it is possible to turn the pages one by one and return to the slide h.

  As described above, in the presentation apparatus according to the present embodiment, the presenter's operations are reduced by skipping without displaying a slide that was displayed only for a period less than the time indicated by the threshold. The burden will be reduced and the presentation will be facilitated.

(Second Embodiment)
In the second embodiment, whether or not the presentation time of each slide was displayed for a period longer than the time indicated by the threshold in the first embodiment was used as a judgment criterion. This is based on whether or not it is judged.

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

  As illustrated in FIG. 6, the terminal 21 according to the present embodiment includes 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 for example, a notebook personal computer or a PDA is representative. 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 during the presentation, and is not limited to those listed here.

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

  The display unit 23 reads out slide data to be displayed next from the storage unit 22 and transmits it to the communication unit 24 in accordance with, for example, a page turning instruction sent from the presenter. 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 unit 24 transmits the slide data received from the display unit 23 to another information terminal device that displays a slide, such as a projector (not shown). As a communication means, for example, a wired cable such as a VGA cable, a USB cable, or a wireless LAN based on a communication standard such as 802.11b, Bluetooth mainly used for small-scale wireless communication, IrDA (Infrared Data using infrared rays). Wireless communication means such as Association) is used.

  The detection unit 25 determines, for example, from the input information of the microphone for inputting the voice uttered by the presenter whether the presently displayed slide has been explained by the presenter, and the announcement has been made. Or a value indicating that no announcement has been made is output. The detected value is output to and stored in the presentation presence / absence storage unit 26.

  For example, the following method can be used to determine whether or not each slide is announced.

(1) A method for determining whether or not a microphone has picked up sound
For example, the volume of the input sound from a microphone or the like is compared with a volume indicated by a predetermined threshold for removing noise, and if the former value exceeds the latter value, it is determined that there is a presentation. Otherwise, it is a method of determining that there is no announcement.

(2) Method of judging by whether or not the volume of the presenter
For example, the volume of the input sound from a microphone or the like is compared with the volume of the presenter prepared in advance, and if the former value is within a certain allowable range based on the latter value, it is determined that the presentation is present If this is not the case, it is determined that there is no announcement. In the case of this method, in order to determine whether or not the volume is the presenter's volume, the presenter inputs the voice to the microphone at the volume at the time of the presentation in advance and stores the presenter's volume in the terminal 21 before the presentation. Let me.

(3) A method for determining whether or not a character string described in a slide has been read
For example, the result of voice recognition of the input voice from a microphone or the like is compared with the character string described on the slide, and if it is determined that the character string described on the slide has been generated, it is determined that there is a presentation. Otherwise, it is a method of determining that there is no announcement. The determination can be based on, for example, whether or not the result of speech recognition includes all of the character strings described in the slide or a certain percentage or more.

(4) Method of judging based on the voice of the presenter
For example, a feature extracted by performing speech recognition processing on input speech from a microphone or the like is compared with a feature extracted by performing speech recognition processing on the speech of a presenter prepared in advance. This is a method for determining whether the presenter's voice. If it is determined that the voice of the presenter is present, it is determined that it has been announced, and if not, it is determined that it has not been announced. For the determination, for example, it can be based on whether or not the similarity between features obtained by the speech recognition processing is equal to or higher than a reference value.

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

  Of course, in addition to the above, various methods are possible.

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

  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 whose items are a display number, a slide name, and presentation presence / absence information. The display time storage unit 26 includes a search unit 262 that searches information held in the presentation presence / absence table 261 according to a predetermined condition.

  In the method of creating the presentation presence / absence table 261, instead of storing information about all the displayed slides, it is determined that a presentation has been made, that is, only information about a slide having an announcement present is stored. A method is also possible. In this case, the presence / absence information may be omitted from the presence / absence table 261.

  The display time storage unit 26 obtains a slide to be transmitted from the presentation presence / absence table 261 by the search unit 262 in response to a request from the presentation condition selection display unit 27. For the obtained slide, a display request is made to the display unit 23.

  The presentation condition selection display unit 27 has a function for the presenter to select a slide that has been announced by voice. For example, when there was an instruction from the presenter to turn the page for only a slide that was announced, it was determined that the presenter's voice was announced. Among these, the presentation presence / absence storage unit 26 is requested for the most recent slide as viewed from the currently displayed slide or the most recent slide after that.

  FIG. 8 shows an example of a procedure from slide transmission to information storage in the second embodiment. This procedure is performed for each displayed slide. First, the next slide to be displayed is transmitted from the communication unit 24 to another information terminal device (step S31). The detecting unit 25 obtains the presence / absence of the presentation of the currently displayed slide (step S32), and stores the information indicating the presence / absence of the presentation, the slide name, and the display number in association with each other (step S32). Step S33).

  Here, detection of presence / absence of announcement and storage of the information are performed when each slide is first transmitted / displayed from the terminal to another information device terminal. When the same slide is displayed multiple times during the presentation, the presence of the presentation is detected and the stored information is updated every time the slide is requested for transmission or display to another information device terminal. You may do it. For example, a method of updating only when it has been stored without an announcement and an announcement has been detected can be considered.

  The page turning instruction to the display unit 23 and the page turning instruction only for the slide for which the presentation condition selection display unit 27 has been announced are easily operated by operating the keyboard and the mouse as in the first embodiment. Can be given to.

  The specific example is basically the same as that of the first embodiment. For example, in the case of keyboard input, “up arrow key” is used as a “previous slide display command” as an example of an instruction for turning pages one by one. , “Down arrow key” can correspond to “Next slide display command”. As an example of page turning instructions for only the slides that have been announced, the simultaneous pressing of the “shift key” and the “up arrow key” can be used as “the most slides announced before the currently displayed slide. It is possible to correspond to a command for displaying a new one (hereinafter referred to as a third skip display command). Then, when the presenter presses the “Up Arrow Key” or “Down Arrow Key”, the slide of the previous or next page is displayed, while the presenter displays “Shift Key” and “Up Arrow Key”. When is simultaneously pressed, the newest slide among previously announced slides can be displayed. 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, when the “shift key” and “down arrow key” are simultaneously pressed, “the command to display the oldest slide among the slides that have already been announced in the order after the currently displayed slide (hereinafter, , A fourth skip display command) ”. Then, it can be determined that this instruction is given by the presenter pressing the “shift key” and the “down arrow key” simultaneously.

  Further, for example, when the presenter presses the “Home key”, the slide that is displayed first among the already displayed slides can be displayed. Alternatively, by pressing the “shift key” and the “Home key” at the same time, the last displayed slide among the proven slides already announced by voice may be displayed.

  In addition, when the “down arrow key” or the “up arrow key” is kept pressed, the page may be turned at regular time intervals. The slide that has been paged at this time can be regarded as a slide that is not displayed when a third skip display command is instructed later. In order to skip, for example, flag information indicating that a third skip display command is not displayed is provided, or page turning is performed at a time interval shorter than a certain time interval required for page turning. You can do it.

  Further, for example, when the “up arrow key” is pressed n times while the “shift key” is held down, the previous n times of slides that have been announced can be displayed.

  In addition, you may use combining all or one part of said function suitably.

  In the above function, the key setting / operation method is an example, and other key setting / operation methods may be used. Further, it is more preferable for the presenter to reduce the burden on the presenter if the presenter can appropriately set the key setting / operation method.

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

  FIG. 9 shows an example of a procedure when an instruction regarding page turning is given from the presenter in the second embodiment. When an instruction regarding page turning is given from the presenter (step S41), if it is a previous slide display command (step S42), the slide corresponding to the previous page of the currently displayed slide is transmitted to other information terminal devices for display. (Step S43). If it is a next slide display command (step S44), the slide corresponding to the next page of the currently displayed slide is transmitted to other information terminal devices and displayed (step S45). If it is the third skip display command (step S46), the latest slide among the slides announced before the currently displayed slide is transmitted to other information terminal devices for display (step S47). ). If it is the fourth skip display command (step S48), the oldest slide among the slides already announced in the order after the currently displayed slide is transmitted to other information terminal devices for display (step S48). S49). If the instruction is other than that (step S48), processing corresponding to each instruction is performed (step S50).

  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. 5 (a), the presenter gives a presentation while turning the slides a to h one by one by the next slide display command, and when the slide h is displayed, the slides a and c are displayed. , D, h only have been announced.

  In this case, as shown in FIG. 5A, the presenter can turn the slide one page forward and backward by a previous slide display command and a next slide display command. Also, as shown in FIG. 5B, only the slides a, c, d, and h that have been announced by the first skip display command and the second skip display command are used as the target range, and the slides are moved forward and backward within the range. You can turn one page at a time.

  Of course, the previous slide display command, the next slide display command, the first skip display command, and the second skip display command can be arbitrarily used. For example, as shown in FIG. 5C, after the first skip display command causes the slide d to be skipped from the slide h at a stroke, the slides e, f, g, h are displayed by the previous slide display command. Thus, it is possible to turn the pages one by one and return to the slide h.

  As described above, in the presentation apparatus according to the present embodiment, the operation of the presenter is reduced by skipping a slide that has not been presented without displaying it, thereby reducing the burden on the presenter and facilitating the presentation. .

  By the way, it is also possible to carry out by combining the first embodiment and the second embodiment described so far.

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

  At this time, for example, a slide that satisfies at least one of the first condition and the second condition may be displayed, and a slide that does not satisfy any of the conditions may be skipped and not displayed. In addition, for example, only slides that satisfy both the first condition and the second condition may be displayed, and slides that do not satisfy either of the conditions may be skipped and not displayed.

  Also, (1) a slide that satisfies the first condition is a display target, (2) a slide that satisfies the second condition is a display target, and (3) a first condition and a second condition. The presenter can appropriately select a slide satisfying at least one of the above, and (4) a slide satisfying both the first condition and the second condition as a display target. You may do it.

(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 slide satisfying a predetermined condition among the displayed slides is a target for skip display. It is. In the third embodiment, slides that satisfy a predetermined condition among slides displayed on the display screen of the terminal are transmitted to other information terminal devices 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 illustrated in FIG. 10, the terminal 31 of the present embodiment includes a storage unit 32, a display unit 33, a communication unit 34, a measurement unit 35, and a time condition transmission unit 36.

  The terminal 31 is used as a presentation device according to the embodiment of the present invention, and for example, a notebook personal computer or a PDA is representative. 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 during the presentation, and is not limited to those listed here.

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

  The display unit 33 reads out slide data to be displayed next from the storage unit 32 in accordance with, for example, a page turning instruction sent from the presenter, and displays it on a display screen (not shown) included in the display unit 33. Furthermore, the measurement unit 35 is requested to measure “display time”, which is the time that is continuously displayed on the display device included in the specific slide.

  In addition, when a request for transmission of the currently displayed slide to the information terminal device such as a projector is received from the time condition transmission unit 36, the data of the slide to be transmitted is transmitted to the communication unit 34.

  The communication unit 34 transmits the slide data received from the display unit 33 to another information terminal device that displays a slide, such as a projector (not shown). As a communication means, for example, a wired cable such as a VGA cable, a USB cable, or a wireless LAN based on a communication standard such as 802.11b, Bluetooth mainly used for small-scale wireless communication, IrDA (Infrared Data using infrared rays). Wireless communication means such as Association) is used.

  The measuring unit 35 measures the time during which the slide has been displayed. As a method of measuring the “display time” from when a slide is displayed to when the next slide is displayed, for example, with respect to a certain slide, after the measurement request from the display unit 33 is received, the next slide is displayed. This is a method of measuring the elapsed time until there is a measurement request. Then, this measurement result is regarded as the display time of the currently displayed slide. After the measurement, the obtained display time is transmitted to the time condition transmission unit 36.

  The time condition transmission unit 36 determines whether or not to send a specific slide to an information terminal device such as a projector. The time condition transmission 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 the set threshold value, and if the display time is determined to be longer than the time indicated by the threshold value, the slide to be transmitted is to decide. Conversely, when the display time is shorter than the time indicated by the threshold value, it is determined that the slide need not be transmitted.

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

  Also, a method of automatically measuring the time corresponding to this threshold value is possible. For example, the terminal 31 is provided with an operation state for measuring a threshold value, and the presenter clicks a button corresponding to a “command to display a slide on the next page” with a mouse, for example, and continuously several pieces at a certain rhythm. 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 number of pages displayed. Then, this value becomes the average value of the time interval required for page turning. Therefore, the above-described threshold value may be determined based on this value.

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

  FIG. 11 shows an example of a processing procedure according to the present embodiment from when a slide is displayed on a display screen included in the slide until it is transmitted to another information terminal device or is not transmitted. That is, for example, if a slide is newly displayed on the display screen of the terminal by a presenter's page turning instruction or the like (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 included in the display screen is completed before the display time reaches the time indicated by the threshold (steps S63 and S64), the slide is not transmitted to other information terminal devices. In addition, when the display of the slide is completed because the other slide is displayed on the display screen provided by the user, the measurement unit 35 starts measuring the display time for the other slide display (steps S61 and S62). ).

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

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

  As a specific example, for example, in the keyboard input, 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”. Then, when the presenter presses the “up arrow key” or “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 in time, the currently displayed slide is not transmitted to other information terminal devices. Only when the slide is displayed on the display screen of the slide itself for a period longer than the time indicated by the threshold, the slide is transmitted to another information terminal device such as a projector.

  Further, the page is continuously turned while the “up arrow key” is pressed (hereinafter referred to as “first continuous display command”), or the page is returned while the “down arrow key” is pressed (hereinafter referred to as “second key”). In the case of “continuous display command”), the slide display time on the display screen provided by the user may be set shorter than the time indicated by the threshold value.

  At this time, the display time per slide does not reach the time indicated by the threshold except for the slide displayed when the key is released. Therefore, as long as continuous display is performed, slide data is not transmitted one by one, and unnecessary time is not spent on it. For example, for a slide that does not need to be sent to the projector, the user can quickly find the slide to be displayed next while confirming on the display device provided by using this function. When a slide to be displayed is displayed, the slide is kept displayed for a time indicated by a predetermined threshold. Then, the slide data is transmitted and displayed on a projector or the like.

  In addition, you may use combining all or one part of said function suitably.

  In the above function, the key setting / operation method is an example, and other key setting / operation methods may be used. Further, it is more preferable for the presenter to reduce the burden on the presenter if the presenter can appropriately set the key setting / operation method.

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

  FIG. 12 shows an example of a procedure when an instruction regarding page turning is given from the presenter in the third embodiment. When an instruction regarding page turning is given from the presenter (step S71), if it is a previous slide display command (step S72), the slide corresponding to the previous page of the currently displayed slide is transmitted to other information terminal devices for display. (Step S73). If it is the next slide display command (step S74), the slide corresponding to the next page of the currently displayed slide is transmitted to other information terminal devices and displayed (step S75). If the command is the first continuous display command (step S76), the slides prior to the currently displayed slide are successively displayed in succession on the display device provided by itself at a display interval shorter than the time indicated by the threshold value per slide. Is displayed (step S77). If it is the second continuous display display command (step S78), the display itself is provided with a slide given the order after the currently displayed slide at a display interval shorter than the time indicated by the threshold value per slide. The information is sequentially displayed on the device (step S79). If the instruction is other than that (step S80), a process corresponding to each instruction is performed (step S80).

  The presenter uses the above instructions as appropriate, and displays each slide on the display screen of the terminal for a period longer than the time indicated by the threshold, thereby sending the specific slide to other information terminal devices for display. Can be made.

  As described above, the presentation apparatus according to the present embodiment does not transmit slide data that has been displayed for a period shorter than the time indicated by the threshold on the display screen of the terminal itself to other information terminal devices. Therefore, since the amount of communication data can be reduced and the time until one slide is displayed can be shortened, unnecessary time at the time of presentation is reduced and the presentation can be smoothly performed as a whole.
