Description

  In the present invention, a teacher (hereinafter, teachers, lecturers, etc. are collectively referred to as teachers) proposes and gives a lecture to students (hereinafter, students, students, etc., are collectively referred to as students). This is related to a presentation system that makes it possible for the teacher's intention to give his / her lecture intentions using the various research material files accumulated through the Internet, etc. .

  In the current technology, editing, display and playback of materials when a teacher gives a lecture is performed using various presentation software such as PowerPoint (registered trademark) of Microsoft (registered trademark) (for example, patent documents). 1). Reproduction of materials by this kind of software is often performed using a PC. Alternatively, an overhead projector (OHP) may be used. Such material display using presentation software is generally performed by a simple operation of moving forward or backward slide screens one by one according to a certain rule.

  There is also presentation software (for example, see Patent Document 2 by the applicant of the present application) that displays and reproduces explanatory materials according to a flow diagram by combining a flow diagram and a table showing a list of explanatory materials. This presentation software can create a flow diagram that allows two or more explanatory materials to be displayed simultaneously on the screen, so that two or more explanatory materials can be displayed simultaneously during a lecture.

JP-A-8-171550 JP2015-049885A

  However, depending on the situation of the lecture, depending on the teacher's intention, select one of the two or more explanatory materials displayed on the screen at the same time, and focus on the selected explanatory material. Sometimes you want to go. In some cases, two or more explanatory materials that were not scheduled to be displayed simultaneously before the lecture are displayed on the screen at the same time.

  The present invention has been devised under such a background, and allows a teacher to advance his / her lecture philosophy (story) and the displayed expression according to his / her own operation. The purpose is that.

  In order to solve the above-described problems, the present invention includes a flow diagram representing an order in which a plurality of the files are displayed on a screen in a system having a plurality of predetermined files to be presented. A file symbol associated with each of the files, an arrow connecting the file symbols, and a simultaneous group formed by a plurality of the file symbols, and related to the file symbol belonging to the simultaneous group The files to be selected are pre-programmed to be displayed on the screen at the same time, and are selected when the file symbol belonging to the simultaneous group is selected while displaying any of the files. Only the file related to the file symbol is displayed on the screen and the presentation proceeds. To provide a Activation system.

  Here, the file symbol refers to the organization number assigned to each file, and the simultaneous group refers to a group of files that are displayed on the same screen within a fixed time. Say.

  Preferably, the flow diagram further includes a simple system group different from the simultaneous system group formed by a plurality of the file symbols, and the file related to the file symbol belonging to the simple system group is the screen. Pre-programmed to be displayed one by one in the order defined above, and when the file symbol belonging to the simple group is selected while displaying any of the files, the selected The file related to the file symbol is displayed on the screen and proceeds.

  Here, the simple group refers to a group of files that are displayed one by one on the same screen within a predetermined time.

  Preferably, when two or more file symbols are selected, a function of displaying all the files related to each of the selected file symbols simultaneously on the screen and moving forward is further provided.

  In the present invention, while any file is displayed on the screen, the teacher feels that he wants to proceed according to his / her intention, and if a file symbol is selected, the display of the file related to the selected file symbol is started. Proceed to Furthermore, when the selected file symbol is a file symbol belonging to the simultaneous system group (simple system group), only the files related to the selected file symbol can be displayed. Therefore, according to the present invention, the teacher can skip the display of the file scheduled to be displayed and shorten the explanation time and simplify the explanation depending on the situation of the lecture and the understanding level of the students.

Furthermore, when the selected file symbol is a file symbol belonging to the simultaneous system group (simple system group), only the files related to the selected file symbol can be displayed. Therefore, only one of the plurality of files scheduled to be displayed at the same time can be displayed and explained mainly.

  Then, after the selected file is displayed, the next file to be displayed is displayed so as to proceed from the selected file instead of returning to the file before selection. As a result, the efficiency of the presentation is improved and the lecture can be performed smoothly and smoothly. For students, the teacher decides to skip and display the file during the lecture, and the lecture will continue from that file and the lecture will continue.

  In addition, when two or more file symbols are selected, all the files related to the selected file symbol are displayed on the screen at the same time, so the teacher can change multiple files and change the conventional flow diagram even during the lecture. It can also be used for explanation.

Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 is a diagram showing an overall configuration of a presentation system 1 according to an embodiment of the present invention. As illustrated in FIG. 1, the system 1 includes a display 80, a speaker 90, and a presentation device 10. This device usually also has a PC function. For example, a presentation-only machine with a sufficient PC function. The presentation device 10 in the present system 1 is usually installed on a teacher's desk installed in the middle of the presentation hall. The display 80 is installed on the platform of the presentation venue. The speaker 90 is installed on the floor or wall of the presentation venue.

  The presentation device 10 is a device that plays a role of supporting editing and presentation of materials by a teacher giving a lecture at a lecture hall. Before the lecture date, the teacher performs a task of combining the document image file, the still image file, the moving image file, and the audio file that are referred to as the lecture progresses into one data.

  On the day of the lecture day, the teacher brings the presentation device 10 and a booklet document describing the outline of the lecture to the venue, and distributes the booklet document to students attending the lecture as necessary. The teacher then proceeds with the presentation while allowing students to view the various files that have been collected as a single piece of data.

  In FIG. 1, the presentation apparatus 10 includes an image output interface 11, an audio output interface 12, a CPU 13, a RAM 14, a ROM 15, a hard disk 16, a PC display 17, a mouse 18, a keyboard 19, a microphone 20, and a speaker 21. The image output interface 11 outputs an image signal to the display 80 when the display 80 is connected. The audio output interface 12 outputs a sound signal to the speaker 90 when the speaker 90 is connected. The CPU 13 executes various programs stored in the ROM 15 and the hard disk 16. The hard disk 16 stores a general file 16a, a lecture-dedicated file 16b, and a presentation program PR.

  The general file 16a in the hard disk 16 is a file that the teacher manages on a daily basis, and the lecture dedicated file 16b is managed for each lecture, such as the lecture dedicated file 1, the lecture dedicated file 2, and so on. This is a file to be displayed on the screen at the lecture (lecture-only file). The presentation program PR has the following three functions.

a1. Display function This indicates each of the files selected as presentation targets from among the files in the hard disk 16, and the file symbol N and the file symbol N, which are sequentially assigned to be displayed on the screen, are sequentially displayed. This is a function of causing the PC display 17 to display a flow diagram 37 composed of two types of rounded figures SY1 and SY2 indicating the grouping of the arrows LN and files that are connected along with the file names.

b1. Editing function This is done by connecting each file symbol N with an arrow LN in the flow display area 36 on the operation screen 31, or one or more file symbols in a single circle figure SY1 or double circle figure SY2. N is a function for creating a flowchart 37 showing the display order of files by arranging N.

c1. Reproduction Function This is a function for performing a reproduction process for displaying a file related to each file symbol N on the display 80 as shown in the flow chart 37 created by the editing function.

  Next, the operation of this embodiment will be described. The operation of this embodiment is started when the presentation program PR is activated. When the presentation program PR is activated, the CPU 13 displays the operation screen 31 on the PC display 17. FIG. 2 is a diagram showing the operation screen 31. The operation screen 31 includes a title bar 32, a tool bar 33, a flow display area 36, a procedure display area 38, and an operation button screen 39. On the toolbar 33, there are arranged an arrow button 34 for creating an arrow LN and a list display switching button 35 for switching display / non-display of the procedure display area 38. The operation button screen 39 includes a start button 40 for starting playback processing, a display screen switching button 41 for switching display of files from the display 80 to the PC display 17, and a pause button for pausing playback processing. 42. An end button 43 for ending the reproduction process is arranged.

  When the procedure display area 38 is displayed, the list display switching button 35 for switching display / non-display of the procedure display area 38 is recessed. When the list display switching button 35 is left-clicked with the mouse 18 to remove the dent, the procedure display area 38 disappears and the flow display area 36 is displayed on the entire screen. However, the operation button screen 39 continues to be displayed in the lower right corner of the operation screen 31. When the list display switching button 35 is left-clicked again with the mouse 18 and recessed, the procedure display area 38 appears again.

In the flow display area 36, a flow diagram 37 showing the display order of each file is displayed. The flow diagram 37 shows two rectangular figures MK _STR and MK _END surrounding the characters “start” and “end”, a file symbol N indicating each of a plurality of files, an arrow LN connecting the file symbols N, a simple system group It consists of GP1 and simultaneous group GP2. The simple system group GP1 is a graphic group indicating that files related to a plurality of file symbols N arranged in a single circular graphic SY1 are grouped and displayed one by one. The simultaneous group GP2 is a graphic group indicating that files related to a plurality of file symbols N arranged in the double-circle graphic SY2 are grouped and all the files are displayed simultaneously. FIG. 2 shows a state in which the flowchart 37 has been created and completed. The creation operation of the flow diagram 37 will be described later.

  For the simultaneous group GP2 described above, the figure in which the file symbol N is arranged may not be the double circle figure SY2, but may be a double circle polygon. Moreover, although the double-circle figure SY2 of FIG. 2 has shown the perfect circle (perfect circle), an ellipse may be sufficient. In addition, regarding the number of lines of the figure SY2, two (double) when displaying two files at the same time, three (triple) when displaying three files at the same time, and the number of lines according to the number of files displayed at the same time. The number may be changed.

  Further, the file symbols N may not be arranged in the figure SY2, and the file symbols N may be connected by a line without an arrow different from the arrow LN so that a simultaneous system group can be formed.

  Furthermore, similarly, the simple group GP1 does not stick to a single circle. For the file symbol N, the figure may be a circle or a polygon.

  The procedure display area 38 shows names of a plurality of files to be presented. The procedure display area 38 includes the following six types of items. FIG. 2 shows a state in which files are listed by a procedure list creation operation described later and a display time and the like are input.

a2. Procedure number This item indicates the display order of the corresponding file shown in the flow diagram 37, which is a combination of the letter "f" and the display order number. When the corresponding file is displayed, the left side of this item flashes red.

b2. Name This item indicates the file name of the corresponding file.

c2. Display page This item indicates the page number of the booklet material corresponding to the display contents of the corresponding file.

d2. Simple display time This item indicates the display time when a single file is displayed.

e2. Simultaneous display time This item indicates the display time when all of the corresponding files are displayed simultaneously.

f2. Display status (display / stop)
This item is displayed when the corresponding file is displayed, whether it is being displayed (indicating that the displayed text, chart, image, video, etc. is in progress) or stopped (indicating that it is paused). Indicates whether this is the state.

  On this operation screen 31, the teacher makes a procedure list creation operation, a flow diagram creation operation, a playback start operation, a skip playback operation, a simultaneous playback operation by selecting two or more file symbols, a simple / simultaneous switching operation, a pause / resume Operations, screen switching operations, and termination operations can be performed. The contents of each operation are as follows.

a3. Procedure list creation operation In this operation, the teacher drags a desired file in the general file 16a that is regularly managed by the teacher displayed on the screen from the file management software screen to the procedure display area 38. And drop and perform the operation of listing up as a lecture-only file 16b.

  When this operation is performed, the CPU 13 performs the following processing. First, the CPU 13 selects a file selected by drag and drop in a format that can be played by an application in the presentation apparatus 10 (specifically, a predetermined file such as flv, wmv, bmp, pdf, jpg, gif, html, etc.). It is determined whether the file has an extension of. If the selected file is a reproducible file, the CPU 13 generates a copy of the selected file, and uses this copy as a lecture-dedicated file 16b in the corresponding lecture-dedicated folder in the hard disk 16. Store. If the selected file is not a reproducible format file but a general format file, the CPU 13 converts the file into a reproducible format file, and converts the converted file as the lecture-dedicated file 16b. It is stored in a folder dedicated to the corresponding lecture in the hard disk 16.

  After that, the CPU 13 adds the file name of the corresponding file to the “name” item in the procedure display area 38, leaves the “display page” item blank, and sets the “simple display time” item to “0:00”. And the item “simultaneous display time” is displayed as “0:00”. Further, the display order number of the corresponding file indicated by the “procedure number” item in each row of the procedure display area 38 is reassigned in ascending order. By repeating the above operations, the teacher lists the files to be viewed by students during the lecture.

  Further, the teacher left-clicks the item “display page” in the procedure display area 38 to make the item ready for input, and inputs the page number of the booklet material in the item. Depending on the document format, it may be difficult to clarify the page number, which requires some effort.

  In addition, the teacher left-clicks the item “simple display time” in the procedure display area 38 to make the item ready for input, and inputs the display time in the simple system mode.

  In addition, the teacher left-clicks the item “simultaneous display time” in the procedure display area 38 to make the item ready for input, and inputs the display time in the simultaneous system mode.

b3. Flow diagram creation operation In this operation, the teacher drags a rectangular figure MK _END on which the character “END” is displayed in the flow display area 36, and thereby between the MK _STR and MK _END in the flow display area 36. Increase the horizontal spacing of the. Then, the teacher drags and drops a desired line from the procedure display area 38 between MK _STR and MK _END .

After arranging at least one or more file symbols N in the flow display area 36, the teacher makes the arrow button 34 for causing the arrow LN to appear in the flow display area 36 by left clicking with the mouse 18 to be recessed. Then, the teacher holds down the left button of the mouse 18 while holding down the left button of the mouse 18 between the rectangular figure MK _STR or MK _END in the flow display area 36 and the file symbol N or between the two file symbols N. The pointer P is moved.

  When this operation is performed, the CPU 13 causes the arrow LN to connect the two rectangular figures or the file symbol N with the arrow directed to the right side. When the right end of the appearing arrow LN comes into contact with the file symbol N, the CPU 13 sets the numbers of all the file symbols N in the flow display area 36 and the “procedure number” items in each row of the procedure table display area 38. The display order number of the corresponding file to be shown is reassigned in ascending order of the display order number of each file along the direction shown in the flow chart 37.

  In addition, when the teacher wants to group a plurality of files and display them one by one in sequence, the teacher drags the single circle figure SY1 at the lower left in the flow display area 36, and places the single circle figure at a desired position. Make a copy of SY1 appear. Then, a simple system group GP1 is created by placing a file symbol N indicating each of a plurality of desired files on the copied figure SY1.

  If the teacher wants to group a plurality of playback files and display them all at the same time, drag the lower left double circle figure SY2 in the flow display area 36 and copy the figure SY2 to the desired position. Make it appear. Then, the simultaneous symbol group GP2 is created by placing the file symbol N indicating each of the desired plurality of files on the duplicated figure SY2.

FIG. 2 shows a completed flow diagram 37. Referring to this flow chart 37, two rectangular figures MK _STR and MK _END enclosing the characters “start” and “end”, file symbols N of “f2” to “f6” (hereinafter, “file symbols of all” (N is omitted), simultaneous groups “f8” to “f11”, simultaneous groups “f13” to “f14”, “f1” “f7” “f12” not belonging to any group ”And an arrow LN. In this example, the contents of the files related to “f1”, “f7”, and “f12” that do not belong to any group are the title images of simple groups “f2” to “f6” and “f8” to “f11”, respectively. ”Of the simultaneous group and“ f13 ”to“ f14 ”. In this way, by creating the flow diagram 37 so that the group title image does not belong to the group, the teacher can view the group title image and the main file separately. The display order is easy to see.

  In this example, the simple group GP1 of “f2” to “f6” converts only the pages necessary for explanation from the document file composed of a plurality of pages into image files, and displays them one by one. It is a group to make it. The simultaneous group GP2 of “f8” to “f11” is a group for simultaneously displaying four videos and explaining a difference in viewpoint from four directions. The simultaneous system group GP2 of “f13” to “f14” is a group for displaying two images at the same time and comparing the two images for comparison.

  When the flow diagram 37 is completed, the teacher proceeds with the lecture by performing the operations described later. The teacher displays the operation screen 31 on which the flowchart 37 is displayed on the PC display 17 in the first stage of the lecture.

c3. Playback Start Operation In this operation, the teacher starts the playback process described above by left-clicking the start button 40. Alternatively, the reproduction process is started by double-clicking the rectangular figure MK _STR on which the characters “start” are displayed with the left button of the mouse 18. When these operations are performed, the CPU 13 switches the character of the start button 40 from “start” to “resume” and performs a reproduction process. The operation of the button after the character of the start button 40 is switched from “start” to “resume” will be described in a pause / resume operation described later.

When the reproduction process is started, the CPU 13 determines whether or not the rectangular figure MK _STR is in contact with the left end of the arrow LN as shown in FIG. This hit determination is performed in order to move forward in the direction of the arrow LN when it is determined that the contact is made. The contact described here is a state where the rectangular figure MK _STR is in contact with the left end of the arrow LN as shown in FIG. In this state, it is in a contact state in terms of software. There is a tolerance outside the frame of the rectangular figure MK _STR , and even if the left end of the arrow LN is within the tolerance, it is considered to be in contact. When the tolerance is _Δt , if the left end of the arrow LN is more than _Δt away from the rectangular figure MK _STR , the software is in a non-contact state. Hereinafter, this hit determination will be described in detail.

As shown in FIG. 3, the lower left corner of the rectangular figure MK _STR is the origin, the left end of the arrow LN is the coordinate (x _a , y _a ), and the lower left vertex of the rectangular figure MK _STR is the coordinate ( x ₁ , y ₁ ), the lower left vertex is the coordinate (x ₂ , y ₁ ), the upper left vertex is the coordinate (x ₁ , y ₂ ), the upper right vertex is the coordinate (x ₂ , y ₂ ), and the rectangular figure MK _When the tolerance of _STR is _Δt , the x coordinate of the left tolerance boundary of the rectangular figure MK _STR is x ₁ −Δ _t , and the x coordinate of the right tolerance boundary is x ₂ + Δ _t , lower y-coordinate tolerance border y ₁ - [delta _t, y coordinates of the upper tolerance border becomes y _{2 +} delta _t. Left coordinates of the arrow LN _{is, x 1 -Δ t ≦ x a} ≦ x 2 + Δ t, and _determines whether or not true for the conditions of _{y 1 -Δ t ≦ y a ≦} y 2 + Δ t ( FIG. 9). When the condition is satisfied, it is considered that the left end of the arrow LN is in contact with the rectangular figure _MKSTR . This is in a contact state in terms of software. The CPU 13 determines that contact is made in this state. If the condition is not met, the left end of the arrow LN is considered not to be in contact with the rectangular figure MK _STR and is in a non-contact state in terms of software. Note that the determination logic is the same for determining whether or not the right end of the arrow LN described later is in contact with the file symbol N and determining whether or not the file symbol N is in contact with the left end of the arrow LN. It is.

If it is determined in the above hit determination that the rectangular figure MK _STR is in contact with the left end of the arrow LN, the process proceeds to the right end hit determination of the arrow LN. In the example of FIG. 3, whether or not the right end of the arrow LN is in contact with “f1” is determined. When the CPU 13 determines that “f1” is in contact with the right end of the arrow LN in this hit determination, only the file related to “f1” (image of file A.jpg) is displayed in the procedure display area 38. The file is displayed on the display 80 during the “simple display time” of the file (7 seconds). After the time has elapsed, the CPU 13 stops displaying the file. In the following description, description of stopping the display of files is omitted.

  After displaying the file related to “f1”, the CPU 13 determines whether or not “f1” is in contact with the left end of the arrow LN. In the example of FIG. 3, since “f1” is in contact with the left end of the arrow LN, it is next determined whether or not the right end of the arrow LN is in contact with “f2”. Further, “f2” is also arranged in the single circle figure SY1. The fact that “f2” is arranged in the single circle figure SY1 is also determined by the hit determination. Hereinafter, this hit determination will be described in detail.

The hit determination described above compares the radius of the single circle figure SY1 with the distance from the center point of the single circle figure SY1 to each vertex of “f2”, and the radius of the single circle figure SY1 is within the distance. It is to determine whether it is longer than one. Specifically, referring to FIG. 3 as an example, if the center point of the single circle figure SY1 is 0, and each vertex of “f2” is A, B, C, D, the center point of the single circle figure SY1 To “f2”, the distance from the center point 0 to A is 0-A, the distance from the center point 0 to B is 0-B, and the distance from the center point 0 to C is 0− C, the distance from the center point 0 to D is 0-D. Whether the radius of the single circle figure SY1 is r, whether r ≧ 0-A, r ≧ 0-B, r ≧ 0-C, or r ≧ 0-D is satisfied. Determine. If the condition is satisfied, it is determined that “f2” is arranged in the single circle figure SY1. If neither of the conditions is satisfied, it is determined that “f2” is not arranged in the single circle figure SY1 (see FIG. 10). In the example of FIG. 3, since the conditions r ≧ 0-B and r ≧ 0-C are true, it is determined that “f2” is arranged in the single circle figure SY1.

As a result of the hit determination described above, it is determined that “f2” is also arranged in the single circle figure SY1, so only the file related to “f2” (image of file B.jpg) is stored in the procedure display area 38. It is displayed on the display 80 during the “simple display time” of the file shown (25 seconds).

  After displaying the file related to “f2”, the CPU 13 determines whether or not the file symbol N is arranged in the single circle graphic SY1 in the clockwise direction from “f2” by the hit determination described above. In the example of FIG. 3, since “f3” is arranged, the CPU 13 determines that “f3” is arranged in the single circle figure SY1, and the file related to “f3” (file C.jpg Only the “image” is displayed on the display 80 during the “simple display time” of the file indicated in the procedure display area 38 (15 seconds). For the files related to “f4” to “f6” after the display of the files related to “f3”, the CPU 13 similarly determines that “f4” to “f6” are arranged by the hit determination described above. The corresponding files are displayed on the display 80 one by one.

  Further, when the file symbol N that is in contact with the right end of the arrow LN is also arranged in the double-circle figure SY2, as shown by “f8” in FIG. 4, the CPU 13 also executes “f9” to “f11”. It determines with arrange | positioning to the said double-circle figure SY2. Then, the size of all the files related to “f8” to “f11” arranged in the double circle graphic SY2 is adjusted so that all the files can fit in the display 80, and the procedure display area 38 is displayed. During the “simultaneous display time” of the displayed file, the files are simultaneously displayed on the display 80. By adjusting the size of the CPU 13, the teacher can save time and effort to adjust the size so that all the files fit on the display 80. The determination logic for determining whether or not “f8” to “f11” are arranged in the double-circle graphic SY2 is based on whether or not “f2” is arranged in the single-circle graphic SY1. It is the same as the hit determination. However, here, since “f8” to “f11” are arranged in a double-circle figure SY2, when it is determined that “f8” is arranged, a file related to “f8” is immediately displayed. It is determined that “f9” to “f11” are also arranged without displaying them, and all related files are displayed simultaneously.

  In addition to the file reproduction process, the CPU 13 blinks the file symbol N indicating the file being displayed in the flowchart 37 in red.

d3. Skip playback operation In this operation, the teacher double-clicks the desired arrow LN in the flowchart 37 with the left button while any file is being displayed. When this operation is performed, the CPU 13 stops displaying the file, determines whether or not the right end of the arrow LN selected by double-clicking is in contact with the material number N, and determines that it is in contact. When the determination is made, the display of the files related to the file symbol N and thereafter is performed as shown in the flow diagram 37 as described above.

  If the teacher double-clicks the desired file symbol N with the left button while displaying any file, the CPU 13 stops displaying the file and relates to the file symbol N selected by double-clicking. Only the selected file is displayed on the display 80. After this display is completed, the CPU 13 determines whether or not the file symbol N is arranged in the double circle figure SY2. If it is determined that it is arranged in the double-circle graphic SY2, whether or not the subsequent file symbol N is arranged in the double-circle graphic SY2 is determined. The files related to the file symbol N determined to be arranged in the double circle graphic SY2 by the hit determination are displayed on the display 80 one by one in the numerical order. As a result, the teacher can select one of a plurality of files that are scheduled to be displayed at the same time in advance and display only the contents of the selected file so as to focus on the explanation. Examples will be described below.

  Specifically, referring to FIG. 5, when all of the files related to “f8” to “f11” are displayed on the display 80 at the same time, when the teacher double-clicks “f10”, the CPU 13 stops the display. Then, only the file (file J.avi) related to “f10” is displayed on the display 80. After displaying the file related to “f10”, the CPU 13 determines whether or not “f10” is arranged in the double-circle graphic SY2. In this example, since it is determined that “f10” is arranged in the double-circle figure SY2, whether or not the number after “f10” is arranged in the double-circle figure SY2 is determined. I do. In this example, since it is determined that “f11” is also arranged in the double circle graphic SY2, the process proceeds from “f10” to “f11”, and the file related to “f11” (file K.avi) Are displayed on the display 80. By this, the teacher can skip the display of the files related to “f8” and “f9” depending on the status of the lecture and the degree of understanding of the students, and shorten the explanation time and simplify the explanation. Further, the files related to “f10” and “f11” can be displayed one by one in order and can be explained mainly.

  In the above hit determination, if it is determined that the selected file symbol N or the subsequent file symbol N is not arranged in the double circle figure SY2, as described above, The display of the file related to the file symbol N of the number is performed as shown in the flowchart.

  If a teacher selects a desired file symbol N belonging to the simple group GP1 by clicking with the left button while displaying one of the files, the CPU 13 reserves the reservation as shown in FIG. Button 67 is displayed. When the teacher clicks the reservation button 67 with the left button, after the display time of the file being displayed has expired, the file is displayed as shown in the flow diagram 37 from the file associated with the selected file symbol N. . As a result, the teacher can shorten the explanation time and simplify the explanation by skipping the display of the file that the teacher feels that the explanation is unnecessary, depending on the situation of the lecture and the degree of understanding of the students. Examples will be described below.

  As a specific example, while the file related to “f1” is being displayed on the display 80, if the teacher selects “f6” by clicking with the left button, the CPU 13 displays a reservation button 67 in the vicinity of “f6”. When the teacher clicks the reservation button 67 with the left button, the CPU 13 selects the file related to “f1” being displayed during the “simple display time” of the file indicated in the procedure display area 38 (7 seconds). The file related to “f6” selected by the teacher is displayed on the display 80 during the “simple display time” of the file shown in the procedure display area 38 (15 seconds). After displaying the file related to “f6”, the CPU 13 displays the file related to “f7” on the display 80 this time, as shown in the flow chart 37. As a result, the teacher skips the display of the files related to “f2” to “f5” that he / she felt unnecessary to explain, and advances the display from the file related to “f6”, thereby shortening the explanation time and simplifying the explanation. Can be made.

  The reservation button 67 not only selects the file symbol N belonging to the simple group GP1, but also selects the file symbol N that does not belong to any group when the file symbol N belonging to the simultaneous group GP2 is selected. Or when a plurality of file symbols N to be described later are selected and the teacher clicks the reservation button 67 with the left button, the file is selected after the display time of the file being displayed has expired. It is also possible to display a file related to the file symbol N. As a result, it is possible to display the selected file after waiting for the display time of the file being displayed to expire.

e3. Simultaneous playback operation by selecting two or more file symbols After the teacher selects two or more desired file symbols N by clicking the left button while pressing the shift key, one of the selected file symbols N is selected. When double-clicking with the left button, the CPU 13 adjusts the size evenly so that all the files related to the selected file symbols N can be accommodated on the display 80, and displays all the files on the display 80 simultaneously. To do. After the simultaneous display is completed, the CPU 13 performs the above-described hit determination on the largest number among the selected file symbols N, and the file associated with the file symbol N of the subsequent number is determined. Display. This allows the teacher to display and explain two or more files that were not scheduled to be displayed simultaneously before the lecture. Some examples are given below.

(1) Select “f4” and “f5” and double-click “f5” to display two simultaneous screens.
A specific description will be given below with reference to FIG. 6 as an example. While the reproduction process is started and the file related to “f1” is displayed on the display 80, the teacher presses the left button while pressing the shift key on “f4” and “f5”. After clicking to select “f5”, the CPU 13 stops this display and adjusts the size evenly so that the two files related to “f4” and “f5” can be accommodated on the display 80. The two files are displayed on the display 80 at the same time. After the simultaneous display ends, the CPU 13 performs the hit determination described above for the largest number “f5” of the selected file symbols N. In this example, “f5” is arranged in the single circle figure SY1, and “f6” is arranged in the single circle figure SY1 in the clockwise direction from “f5”. Display only relevant files and proceed with playback. As a result, even if the teacher is the simple group GP1, the teacher can select some of the files belonging to the simple group GP1 and display the files at the same time for explanation.

(2) “f10” and “f11” are selected from the four simultaneous screens “f8” to “f11”, and one of the file symbols N is double-clicked to represent the two simultaneous screens.
When the teacher selects “f10” and “f11” by clicking with the left button while pressing the shift key and then double-clicking one of the file symbols N, the CPU 13 selects two of “f10” and “f11”. The sizes are adjusted so that the two files can fit on the display 80, and the two files are simultaneously displayed on the display 80. As a result, the teacher previously displayed all the files related to “f8” to “f11” before the lecture, and simultaneously displayed two files related to “f10” and “f11”. Will be able to change.

(3) Select three of the title images “f1”, “f7”, “f12” and double-click on any file symbol N to represent the three simultaneous screens of the title image and explain the outline of the lecture Is realized.
For example, after the teacher selects “f1”, “f7”, and “f12” indicating the title image files of each group by clicking the left button while pressing the shift key, one of the file symbols N is selected. When double-clicking, the CPU 13 adjusts the size evenly so that the three files related to “f1”, “f7”, and “f12” can fit on the display 80, and simultaneously displays the three files on the display 80. To do. As a result, the teacher can simultaneously display all the title images of the files explained in the lecture and explain the outline of the lecture contents.

(4) Select “f7” for the title image and “f8” for the central file of the simultaneous group, and double-click either file symbol N to display the two simultaneous screens, realizing the outline of the group To do.
For example, the teacher holds down “f7” indicating the title image file of the simultaneous group GP2 to which “f8” to “f11” belong and “f8” indicating the file serving as the center of the simultaneous group GP2 while pressing the shift key. After clicking and selecting with the left button, when one of the file symbols N is double-clicked, the CPU 13 adjusts the size evenly so that the two files related to “f7” and “f8” fit on the display 80, The two files are displayed on the display 80 at the same time. This allows the teacher to simultaneously display and explain the group title image and the most important file in the group.

(5) For example, after the teacher selects “f2”, “f8”, and “f13” indicating the central file of each group in this example by clicking the left button while pressing the shift key, When the file symbol N is double-clicked, the CPU 13 adjusts the size evenly so that the three files related to “f2”, “f8”, and “f13” fit in the display 80, and the three files are displayed on the display 80. Display on top at the same time. This allows the teacher to display all the files at the center of the file explained in the lecture at the same time and explain the outline of the lecture more specifically than the simultaneous display of the title image. become.

(6) In FIG. 2, when “f5” or “f6” is selected during the display time of the file related to “f1”, two screens of the files related to “f5” and “f6” are displayed. At the same time, when the display time has passed, the display of the file related to “f7” is started. Alternatively, when “f10” or “f11” is selected during the display time of the file related to “f7”, two screens of the files related to “f10” and “f11” are displayed at the same time, and the display When time passes, the file related to “f12” may be transferred.

  As described above, the teacher selects two or more file symbols N, and then double-clicks one of the file symbols N to realize simultaneous display of files related to the selected file symbol N. However, even if the button that performs the same operation as when double-clicked with the left button is provided somewhere on the operation screen 31 and the teacher selects two or more desired file symbols N, the button is also selected. It is also possible to realize simultaneous display of files related to the file symbol N. As a result, the teacher can realize simultaneous display of a plurality of selected files with a simpler operation.

f3. Simple / simultaneous switching operation While displaying a plurality of files grouped by the double-circle graphic SY2, the CPU 13 displays “simple” and “right” next to the double-circle graphic SY2, as shown in FIG. A simple system operation button 65 and a simultaneous system operation button 66 on which “simultaneous” is displayed are displayed. When the teacher left-clicks the simple operation button 65, the CPU 13 switches the display of the file from the simultaneous display to the simple display that displays the files one by one. When the teacher left-clicks the simultaneous operation button 66 after switching to the simple display, the CPU 13 returns the display of the file from the simple display to the simultaneous display. Alternatively, while displaying a plurality of files grouped by the single circle figure SY1, the CPU 13 displays a simple system operation button 65 in the same manner as described above to the right of the single circle figure SY1, as shown in FIG. And the simultaneous operation button 66 is displayed. When the teacher left-clicks the simultaneous operation button 66, the CPU 13 switches the display of the file from the simple display to the simultaneous display. When the teacher left-clicks the simple operation button 65 after switching to the simultaneous display, the CPU 13 returns the display of the file from the simultaneous display to the simple display.

g3. Pause / Resume Operation In this operation, the teacher left-clicks the pause button 42 or the pause button 64. When the pause button 42 or the pause button 64 is left-clicked, the CPU 13 pauses the file reproduction process. When the start button 40 or the resume button 63 in which the character of the button is changed to “resume” by the above-described reproduction start operation is left-clicked, the reproduction process is resumed. The resume button 63 and the pause button 64 are displayed in the vicinity of the file symbol N indicating the file while any file is being displayed.

h3. Screen Switching Operation In this operation, the teacher left-clicks the display screen switching button 40. When the display screen switching button 40 is left-clicked, the CPU 13 moves the file display to the PC display 17, and when left-clicked again, the file display is returned to the display 80 and the operation screen 31 is displayed on the PC display. 17 is displayed again.

i3. End Operation In this operation, the teacher left-clicks the end button 43 or double-clicks the rectangular figure MK _END displaying the characters “ _END” with the left button. When this operation is performed, the CPU 13 ends the reproduction and returns the character of the button of the start button 40 whose button character is switched by the reproduction start operation to “start”.

The above is the details of the configuration of the present embodiment. According to this embodiment, the following effects can be obtained.
First, in the present embodiment, when an operation for double-clicking the file symbol N is performed while any file is being displayed, the CPU 13 stops displaying the file, and the double-clicked file symbol is displayed. Only files related to N are displayed. At this time, if the file symbol N is arranged in the double circle graphic SY2 (single circle graphic SY1), the CPU 13 determines that the file related to the file symbol N arranged in the graphic SY2 (SY1) is , Display one by one in numerical order. As a result, the teacher can shorten the explanation time and simplify the explanation by skipping the display of the file scheduled to be displayed depending on the situation of the lecture and the understanding level of the students. Furthermore, only one of a plurality of files scheduled to be displayed at the same time can be displayed and explained mainly.

  Second, in this embodiment, when two or more file symbols N are selected and then an operation of double-clicking the file symbol N is performed, the CPU 13 relates to the selected file symbol N. All of the files are displayed on the display 80 simultaneously. This allows the teacher to display and explain two or more files that were not scheduled to be displayed simultaneously before the lecture.

  As mentioned above, although one Embodiment of this invention was described, you may add the following modifications (1)-(7) to this embodiment.

(1) In the above embodiment, the file symbol N in the flow display area 36 is arranged so that the display order is from left to right. However, the file symbols N may be arranged so that the display order is from right to left, or from top to bottom and from bottom to top. These can be performed by a combination of the arrangement of the file symbol N and the arrow LN. Thus, the teacher can create the flow diagram 37 without worrying about the direction of the flow diagram 37.

(2) In the above embodiment, the output image of the presentation device 10 has been described as being displayed on the display 80. However, a projector may be used instead of the display 80. As a result, even in a lecture hall where a large display is not installed, the contents of the file can be shown large throughout the hall by using a projector.

(3) In the above embodiment, when the list display switching button 35 is left-clicked to remove the dent, the procedure display area 38 disappears and the flow display area 36 is displayed on the entire screen. However, in addition to the list display switching button 35, a button for deleting the flow display area 36 and displaying the procedure display area 38 alone on the entire screen may be provided. As a result, when the number of files to be presented is large and the flow display area 36 is displayed, the names of files that could not be seen without scrolling the procedure display area 38 can be seen without scrolling.

(4) In the above embodiment, a thumbnail image of a file may appear under the file symbol N in the flow display area 36. As a result, the teacher can check the display contents without displaying the file.

(5) In the above embodiment, the flow diagram 37 in the flow display area 36 shows the flow from the rectangular figure MK _STR displaying the “start” character to the rectangular figure MK _END displaying the “end” character. There was only one route (procedure) between them. However, some teachers may want to prepare multiple routes and select the route of the file to be displayed by the student being lectured. In this case, a flow diagram 37 having a plurality of routes from the rectangular figure MK _STR to the rectangular figure MK _END can be created, and the arrow LN extending from the rectangular figure MK _STR is double-clicked and selected. Allows the root of the file to be displayed to be selected. As a result, the teacher can switch the display procedure of the file to be presented by the student to be lectured.

(6) In the embodiment described above, the file is dragged and dropped to the procedure display area 38 and then dragged and dropped to the flow display area 36. However, the file may be directly dragged and dropped into the flow display area 36. This allows the teacher to create the flow diagram 37 at the same time as importing the file.

(7) In the above embodiment, it has been described that the playback process is started from the top of the flow diagram 37 by left-clicking the start button 40. However, when the teacher selects the arrow LN or the file symbol N and left-clicks the start button 40 so that the teacher's intention is reflected in the operation, the file related to the file symbol N ahead of the selected arrow LN The reproduction process may be performed from the file related to the selected file symbol N as shown in the flowchart of FIG. As a result, the file playback process starts even in the middle of the flow diagram 37 (display procedure), so the teacher skips the top of the flow diagram 37 and starts the lecture in the middle of the flow diagram 37. Will be able to.
