Description

  The present invention relates to a content presentation device, a content presentation program, and a content presentation method, and more particularly to a content presentation device, a content presentation program, and a content presentation method that are used as digital signage, for example.

  Non-patent document 1 discloses a technique related to this type of content presentation apparatus. According to this non-patent document 1, it is described that the most commonly used method for presenting search results of information retrieval is a method of presenting summary information of retrieved documents in a vertical arrangement. Yes. This search result list is well known as Search Engine Results Page l.c. (SERPs). In addition, an important characteristic regarding the search result surrogate returned by a modern Web search engine is that a summary sentence considering a query word input by a search user is presented. This is called a keyword-in-context (KWIC) extraction method and is used to present search results.

  In the field of document analysis, it is common to analyze a single text or a text collection by extracting concordance. Concordance means an index that arranges all words in a text in alphabetical order and displays them together with the context in which the words appear. In a typical document concordance, texts containing the words of interest are displayed side by side so that the words of interest are arranged at the center of the concordance view. Thereby, the user understands the characteristics of the interested word (language) from the surrounding text (context before and after) of the interested word, and analyzes the structure and content of the document itself.

User interface for information retrieval Marti A. By Hearst, directed by Kazutoshi Kakutani and Katsumi Tanaka, published by Kyoritsu Publishing, April 10, 2011, first edition, p131, pp134-135, p303, pp308-309

  SERPs and document concordance, including KWIC, are used as an interface for information retrieval and text analysis. The user inputs or selects a query word or a word of interest, and is a passive type that responds to user input. Is. Therefore, for example, many distribution media such as digital signage do not accept user operations, so it is difficult to visualize content using SERPs including KWIC and document concordance services.

  Therefore, a main object of the present invention is to provide a novel content presentation device, content presentation program, and content presentation method.

FIG. 15 is a flowchart showing another part of the content control process of another embodiment.

  With reference to FIG. 1, a content presentation device 10 of this embodiment includes a general-purpose computer 12, and a display device 14 is connected to the computer 12. The computer 12 includes a CPU 20, and the CPU 20 is connected to the HDD 24, the RAM 26, the communication circuit 28, and the display driver 30 via the bus 22. The display device 14 described above is connected to the display driver 30.

  The CPU 20 governs overall control of the content control apparatus 10. The HDD 24 mainly stores the content presentation program of this embodiment and data (content data) corresponding to a plurality of contents. The RAM 26 is used as a buffer area or work area for the CPU 20. The communication circuit 28 is a circuit for communicating with other computers via a network such as the Internet or a LAN. The display driver 30 executes display control of the display device 14 under the instruction of the CPU 20. The display driver 30 includes a video memory 30a. The display device 14 is typically an LCD, and in this embodiment, a display device having a relatively large screen size is used.

  For example, the content presentation device 10 is used as a digital signage or a screen saver, and at least the display device 14 is an outer wall or inner wall of a building such as a shopping mall, supermarket, department store, bank, movie theater, hotel, hospital, airport, station, or museum. Or it is arranged in the passage. That is, the display device 14 (content presentation device 10) is applied to a place where many people gather.

  Although not shown, the display device 14 has a screen on which a plurality of lanes (columns in this embodiment) are formed, and in each lane, a character string (segment, sentence) is located above the display device 14 from above. Is displayed. The character string is displayed as a single vertical writing, and is treated as a band-shaped content (band-shaped content). In this embodiment, the character string is a Twitter comment (Tweet).

  In this embodiment, a part of Twitter's comment data (Tweet stream data) in a certain period (for example, one week) is read, and among the read comments, the most frequently used keywords (hereinafter, Only comments (character strings) having “main keywords” are extracted. That is, data about a plurality of comments including the main keyword is stored in the HDD 24.

  In this embodiment, the keyword is a noun and is extracted by morphological analysis of each comment. However, the keyword may be another part of speech (for example, an adjective, adverb, or verb). In this embodiment, the main keyword is the same keyword, but a keyword having a similar meaning may be included. The same applies to the sub-keyword described later.

  In this embodiment, keywords (hereinafter referred to as “sub-keywords”) included in more than a predetermined number (for example, a number corresponding to 80% of all comments) of a plurality of comments including the main keyword are also detected. Is done. Although detailed explanation is omitted, the main keyword and sub-keyword information is also stored together with the comment stored in the HDD 24, that is, the data of the strip-shaped content.

  Such processing is executed in advance, and the data of the belt-shaped content is stored in the HDD 24. For simplicity, assume that the HDD 24 stores and presents strip content data for one main keyword. However, it is also possible to store band-shaped content data for each of a plurality of different main keywords and present them sequentially or randomly for each group of band-shaped contents of the same main keyword. In such a case, content is presented for each theme (main keyword).

  Specific examples of display (presentation) of strip-shaped content are shown in FIGS. Here, the band-shaped content of this embodiment includes a certain target object. The attention object is a specific element among the elements constituting the belt-shaped content, and means an element having the same or similar characteristics or concept with other belt-shaped content. In this embodiment, the target of attention is a main keyword or a sub keyword.

  2 to 5 show how the screen of the display device 14 changes over time. In brief, on the screen shown in FIG. 2, the band-like content of each lane is moved upward while accelerating. In the screen shown in FIG. 3, the position of interest (in this embodiment, the head of the main keyword) is set in the deceleration area 120 (see FIG. 8) set before the reference position Q set in the substantially upper and lower half of the screen. Position) P is decelerated in order from the belt-like content at which P (see FIGS. 7 and 8) has reached. However, the belt-like content in which the head position P of the main keyword has not reached the deceleration area 120 is moved upward while still accelerating. In the screen shown in FIG. 4, the main keywords are displayed so as to be aligned at the reference position Q. Thereafter, on the screen shown in FIG. 5, the band-like content of each lane moves further upward while accelerating, and is moved (exited) outside the screen.

  In this way, moving and displaying the band-like content is such that a person viewing the screen of the display device 14 can intuitively understand the change in the screen, and reads the comment from the beginning to the end without moving the line of sight. Because it can. That is, the entire band-shaped content can be easily grasped.

  In addition, since the character or character string of the main keyword has a width, in this embodiment, the attention position for controlling the movement of the belt-shaped content is set to the head position P of the main keyword that is the object of attention. It is not necessary to be limited to this. The center (center) of the width (length) of the main keyword may be set as the target position. Alternatively, instead of the attention position, the entire main keyword may be set as the attention area (attention area).

  In the example shown in FIGS. 2 to 5, the main keyword is “Nagano” and is shown in bold. The sub-keyword is “earthquake” and is shown in italics. As described above, in this embodiment, the main keyword and the sub-keyword are displayed so as to be distinguishable from other words depending on the thickness of the character and the font style, but it is not necessary to be limited to this. For example, the main keyword may be shown in red, the sub-keyword may be shown in yellow, and the other words may be shown in black. In addition, markers of different colors may be attached to the main keyword and sub-keyword. Alternatively, the main keyword and sub-keyword may be displayed in a size larger than that of other words, or the main keyword may be displayed blinking depending on the case. These are examples and should not be limited, and two or more of these may be applied in combination. In other words, the main keywords and sub-keywords can be easily distinguished from other words by making the display mode different from other words depending on at least one element of appearance (shape), color, decoration, and appearance. .

  Furthermore, in FIG. 2 to FIG. 5, only one sub-keyword is shown for simplicity, but there may be a plurality of sub-keywords as described above. Therefore, different sub-keywords may be displayed so as to be identifiable.

  2-5, 27 lanes are provided, but the number of lanes may be larger or smaller. It is set appropriately depending on the size of the display device 14.

  In this embodiment, movement control of the belt-like content is performed in each lane. This is because each band-like content is displayed so that the main keywords are aligned at the reference position Q, as shown in FIG. 4, and the position of the main keyword may be different in each band-like content. However, the position of the main keyword means, for example, the distance from the top of the strip-shaped content including the main keyword to the top position P of the main keyword.

  Hereinafter, the arrangement and movement control of the band-shaped content will be described. Hereinafter, when it is not necessary to distinguish each strip-shaped content, it will be described using the reference symbol “C”. However, when each strip-shaped content needs to be distinguished, an individual reference symbol is used. I will explain.

  For example, as shown in FIG. 6, the entire area 100 of the video memory 30 a includes the entire display area 110 of the display device 14. The position (address) of the entire area 100 of the video memory 30a is managed in a two-dimensional coordinate system. The horizontal direction in FIG. 6 is the X axis of the two-dimensional coordinate system, and the vertical direction is the Y axis of the two-dimensional coordinate system. Further, the right direction in FIG. 6 is the positive direction of the X axis, and the upward direction is the positive direction of the Y axis. Further, the lower left vertex of the entire area 100 is the origin O. Furthermore, as shown in FIG. 6, the reference position Q shown in FIGS. 2 to 5 is set to a position corresponding to a position obtained by dividing the entire display area 110 into upper and lower halves.

  As shown in FIG. 6, when the display is started, the band-like contents C1, C2, C3, C4, C5,... Of each lane are arranged so that the respective heads are located at the lower end 110b of the entire display area 110 ( Drawn). However, the lower end 110b corresponds to the lower end of the screen of the display device 14, and may be referred to as a “start position” below. Similarly, the upper end 110a illustrated in FIG. 6 corresponds to the upper end of the screen of the display device 14, and may be referred to as “exit position” below.

  Next, movement control of the band-shaped content C will be described. As shown in FIG. 7, when attention is paid to some band-like contents C1, C2, C3, C4, and C5, the positions of the main keywords may be different as described above. However, FIG. 7 shows a positional relationship at a certain timing when the band-shaped contents C1, C2, C3, C4, and C5 are moved toward the reference position. Further, in FIG. 7, the top position P of the main keyword included in the band-like contents C1, C2, C3, C4, and C5 is indicated by P1, P2, P3, P4, and P5, respectively. Therefore, the distance h (here, h1, h2, h3, h4, h5) between the reference position Q and the head position P of the main keyword may be different.

  As described above, in this embodiment, each strip content C is moved so that the main keywords of each strip content C are aligned at the reference position Q. For this reason, in calculating the speed v (here, v1, v2, v3, v4, v5) at the time of moving the strip content C1, C2, C3, C4, C5, the strip content C1 according to the distance h. , C2, C3, C4, C5 acceleration a (here, a1, a2, a3, a4, a5) is changed.

  In this embodiment, the acceleration a is calculated according to the spring model. However, the acceleration a or the speed v proportional to the distance h from the head position P of the main keyword to the reference position Q may be determined in advance. As shown in the lower part of FIG. 7, the magnitude relationship of the distance h is h3> h4> h1> h2 = h5. Therefore, the magnitude relationship of the acceleration a is a3> a4> a1> a2 = a5.

Specifically, the moving speed v of the belt-like content C is calculated according to Equation 1 based on the numerical solution method using the Euler method, but other numerical solution methods such as the Runge-Kutta method may be used. However, v ₀ is an initial speed, a default value is set for the first time, and the initial speed v ₀ is updated at the speed v each time the speed v is calculated by movement control. Note that Δt is the elapsed time from the previous calculation time. The acceleration a is determined by the product of the spring constant k and the distance variable x according to Equation 2. The spring constant k is a numerical value obtained empirically by the developer or programmer of the content presentation device 10 through experiments or the like. Further, the mass component of the strip-shaped content C is “1”, and is omitted in Equation 2. However, until the leading position P of the strip-shaped content C reaches the reference position Q, the distance h is substituted into the variable x in Equation 2.

[Equation 1]
v = v ₀ + a × Δt
[Equation 2]
a = −kx
In this way, the speeds v1, v2, v3, v4, and v5 of the strip-shaped contents C1, C2, C3, C4, and C5 are calculated and the screen of the display device 14 is updated (1 frame = 1/30 seconds). A travel distance is further calculated. Accordingly, in the video memory 30a, the strip-shaped contents C1, C2, C3, C4, and C5 are drawn at the position moved upward by the calculated movement distance in the next frame. Such processing is repeated, and the respective band-like contents C1, C2, C3, C4, and C5 are moved upward as shown in FIGS.

  Although omitted in FIG. 6, a deceleration region 120 is provided in front of the reference position Q as shown in FIG. In this embodiment, the deceleration region 120 has a predetermined width defined by the upper end 120a and the lower end 120b in the Y-axis direction, and the upper end 120a overlaps the reference position Q. In FIG. 8, only two strip contents C1 and C2 are shown for simplicity.

In this embodiment, the head position P of the respective strip-like content C is reached to the reduction region 120, the deceleration component a ₁ is added to the calculated acceleration a. However, in this embodiment, since the strip-shaped content C moves from the lower end (lower end 110b) to the upper end (upper end 110a) of the screen, the Y coordinate of the lower end 120b of the deceleration area 120 and the main keyword included in the strip-shaped content C It is determined whether or not the deceleration area 120 has been reached based on the magnitude relationship with the Y coordinate of the first position P.

For example, the deceleration component a ₁ is determined by a magnitude proportional to the speed v, similarly to the air resistance. Thus, in this embodiment, the deceleration area 120, the deceleration component a ₁ indicated by the number 3 is subtracted from the acceleration a is calculated according to Equation 2. However, f is a proportionality coefficient (f> 0).

[Equation 3]
a ₁ = fv
However, the deceleration component a ₁ may be added from the start of the movement of the belt-like content C, and the proportional coefficient f may be increased when entering the deceleration region 120.

  Further, when the leading position P of the main keyword included in the strip-shaped content C reaches the reference position Q, thereafter, as shown in FIG. 9, the distance d () between the upper end 110a (exit position) and the rear end of the strip-shaped content C The acceleration a is calculated according to d1, d2, d3, d4, d5). Specifically, the distance d is substituted into the variable x in Equation 2, and the acceleration a is calculated. In this embodiment, since a large number of strip-like contents C are displayed in a plurality of times, in each lane, after the currently displayed strip-like content C goes out of the screen (leaves), the next strip-like content C is displayed. Is placed. Therefore, it is necessary to display the strip-shaped contents C of the second and subsequent lanes so that they are aligned at the reference position Q. For this reason, the timing when the strip-shaped content C goes out of the screen is aligned in each lane.

  FIG. 10 shows an example of a memory map of the RAM 26 shown in FIG. As shown in FIG. 10, the RAM 26 includes a program storage area 50 and a data storage area 52. The program storage area 50 stores a content presentation program, and the content presentation program includes an image generation program 50a, an image display program 50b, a content control program 50c, and the like.

  The image generation program 50 a is a program for generating display image data for displaying a plurality of band-like contents C on the display device 14. The image generation program 50a is also a program for changing the display position of each strip content C whose movement is controlled in accordance with a content control program 50c described later. That is, the display image data is updated. The image display program 50b is a program for outputting display image data generated according to the image generation program 50a to the display device 14. The content control program 50c is a program for arranging (drawing) the band-like content C at the lower end 110b (start position) of the entire display area 110 provided in the video memory 30a and controlling the movement of the band-like content C. is there.

  Although illustration is omitted, the program storage area 50 also stores other programs necessary for content presentation processing.

  In the data storage area 52, content data 52a is stored. The content data 52a is data regarding a plurality of strip content C. In this embodiment, the plurality of strip contents C include the same main keyword.

  Although illustration is omitted, the data storage area 52 stores other data necessary for the content presentation processing, and is provided with a counter (timer) and a flag necessary for the content presentation processing.

  11 and 12 are flowcharts showing the content presentation processing of the CPU 20 shown in FIG. However, the content presentation process shown in FIGS. 11 and 12 is executed for each lane. Here, only content presentation processing for a certain lane (the lane) will be described, but the same applies to other lanes. That is, the content presentation processing for each lane is executed simultaneously in multitasking.

  As shown in FIG. 11, when starting the content presentation process for the lane, the CPU 20 places the content at the start position in step S1. That is, the strip-shaped content C is arranged (drawn) in the lane so that the head position thereof coincides with the position of the lower end 110b of the entire display area 110 provided in the video memory 30a (see FIG. 6).

In the next step S3, it moves the content at an initial velocity v _0. However, in the first time, the initial velocity v ₀ default value is set. In the next step S5, the acceleration a is calculated according to Equation 2. At this time, the distance h between the head position P of the main keyword included in the belt-like content C and the reference position Q is calculated (detected) and substituted into the variable x. In the subsequent step S7, the speed v is calculated according to Equation 1. In step S9, the content is moved. Here, the CPU 20 moves the strip-shaped content C upward by the moving distance obtained by multiplying the speed v calculated in step S7 by the screen update unit time (one frame) based on the numerical solution by the Euler method. . The same applies to steps S21 and S31. However, this is merely an example, and the calculation method (numerical solution) of the movement distance should not be limited as in the calculation method of the speed v.

In step S11, it is determined whether or not the leading position P of the main keyword of the strip-shaped content C has entered the deceleration area 120. If in step S11 "NO", that is, the start position P unless reached the deceleration area 120, in step S13, to update the initial velocity _{v 0 (v 0 = v)} , flow returns to step S5.

On the other hand, if "YES" in the step S11, that is, if the head position P placed in the deceleration region 120, at step S15, the acceleration a is calculated according to Equation 2, in step S17, calculated according to the deceleration component _{a 1} the number 3 and, in step S19, and updates the acceleration a deceleration component _{a 1 (a = a-a} 1). In step S21, the speed v is calculated according to Equation 1. Subsequently, in step S23, the belt-like content C is moved at the decelerated speed v.

As shown in FIG. 12, in the next step S25, it is determined whether or not the content of the lane has reached the reference position Q. That is, the CPU 20 determines whether or not the Y coordinate of the reference position Q and the Y coordinate of the head position P of the main keyword included in the belt-like content C moving in the lane match. If in step S25 "NO", that is, it does not reach the reference position Q, in step S27, to update the initial velocity _{v 0 (v 0 = v)} , flow returns to step S15 shown in FIG. 11. On the other hand, if “YES” in the step S25, that is, if the reference position Q is reached, the acceleration a is calculated according to the equation 2 in a step S29. At this time, the distance d between the upper end 110a (exit position) of the entire display area 110 and the rear end of the belt-like content C is calculated (detected) and substituted into the variable x. However, in step S25, it is determined that the reference position Q has been reached even when the Y coordinate of the head position P is larger than the Y coordinate of the reference position Q.

  Subsequently, the speed v is calculated according to Equation 1 in step S31, and the belt-like content C is moved upward in step S33. That is, the belt-like content C is moved upward without being decelerated. In a succeeding step S35, it is determined whether or not the strip content C has left the screen. Here, the CPU 20 determines whether or not the Y coordinate of the rear end of the strip-shaped content C is equal to or greater than the Y coordinate of the upper end 110a (exit position) of the entire display area 110.

If "NO" in the step S35, that is, if the belt-like content C has not exited out of the screen, in step S37, to update the initial velocity _{v 0 (v 0 = v)} , returns to the step S29. On the other hand, if “YES” in the step S35, that is, if the belt-like content C leaves the screen, it is determined whether or not there is a next content in a step S39.

  If “YES” in the step S39, that is, if there is a next content, the next content is arranged at the start position in a step S41, and the process returns to the step S3 shown in FIG. On the other hand, if “NO” in the step S39, that is, if there is no next content, the content presentation processing of the lane is ended.

  According to this embodiment, the belt-like content is moved and displayed in each lane, and movement control is performed so that main keywords having the same or similar features or concepts included in each belt-like content are aligned at the reference position on the screen. It is possible to know the main keywords having the same or similar features or concepts for all the band-like contents while grasping the entire band-like content. That is, it is excellent for intuitively grasping certain information from a large number of information.

  In this embodiment, the stream data of Twitter's Tweet is read out and the comment (text sentence) is presented as content. However, other text can be used for the comment. For example, a plurality of books ( You may make it acquire a text group from an electronic book) or a blog.

  In this embodiment, the comment is presented as a band-shaped content. However, the present invention is not limited to this. The content may be other content that includes a target of interest having the same or similar features or concepts and can be expressed in a band shape. For example, as other content, a moving image arranged in a film form (still images of a plurality of continuous frames), a score, and a graph (sound waveform, change in stock price, etc.) that changes according to time series are applicable. In the case of a moving image, for example, the target of attention is a certain person or an appearance location (scene) of a certain person. In the case of a musical score, for example, a target of attention is a place where a certain or similar chord progression occurs. Furthermore, in the case of a graph that changes in time series, the target of attention is a location that shows some similar change (abrupt increase or decrease).

  Furthermore, in this embodiment, the band-like content is moved upward, but the moving direction may be another direction. For example, in a horizontally written character string, image, score, or graph, the character may be moved leftward or rightward. Further, for example, the image may be moved downward. That is, the moving direction of the band-shaped content should be appropriately set according to the band-shaped content. For example, when moving leftward or rightward, the reference position is set at an arbitrary position that divides the screen of the display device into left and right. Further, a deceleration area is set from the reference position to the start position side. The calculation method of the acceleration, the speed, and the deceleration component is the same as the contents shown in the above-described embodiment.

  Furthermore, in this embodiment, when the strip content is withdrawn in each lane, the next strip content is arranged. Therefore, in the second and subsequent lanes, the timing is shifted to the timing at which the strip content is arranged in each lane. Will occur. For this reason, in this embodiment, every time the belt-like content is moved, the acceleration and speed are recalculated so that the main keywords of the respective belt-like content are aligned at the reference position. Therefore, if the strip content is allocated to each lane in advance so that the length of each strip content is approximately the same in each lane, the timing at which the strip content is arranged in each lane at each time is determined. Since they can be arranged to some extent, in such a case, the acceleration can be calculated only for the first time. Further, even when the timing for starting the movement of each band-like content is adjusted and the distance h (h1, h2, h3, h4, h5) is set to be equal, the acceleration may be calculated only for the first time. it can.

  Furthermore, in this embodiment, not only passive distribution contents such as digital signage and screen savers, but also interactions according to the purpose of the user are possible. For example, by providing a touch panel on the screen of the display device and tapping on the touch panel, the movement of all the contents (or only the tapped contents) is stopped, or all the contents are flicked on the touch panel. The movement (or only the flicked content only) can be accelerated or decelerated. However, when the content movement direction matches the flick direction, the content movement is accelerated. On the other hand, when the content movement direction and the flick direction are opposite, the content movement is decelerated.

Furthermore, in this embodiment, the belt-like content is accelerated or decelerated when it starts to move, but it may be allowed to remain stationary for a predetermined time (up to several seconds at the reference position). In such a case, in step S25, when the start position P has reached the reference position Q is determined, after the belt-like content is stopped a predetermined time, then the default start moving at an initial velocity v ₀ (Resume) Then, the processing after step S29 may be executed.

  In the content presentation device 10 according to another embodiment, the belt-like content C of all lanes starts to move all at once, and after the main keywords (start position P) included in the belt-like content C of all lanes are aligned at the reference position Q, Since it is the same as the above-described embodiment except that the movement is started (restarted) all at once from the reference position Q, a duplicate description is omitted.

  As shown in FIG. 13, in this other embodiment, the data storage area 52 is provided with a start position flag 52b and a reference position flag 52c. The start position flag 52b is a flag for determining whether or not the strip content C is arranged at the start position of each lane. Although illustration is omitted, the start position flag 52b is composed of a register having the same number of bits as the total number of lanes. Each bit corresponds to each lane. When the strip content C is arranged at the start position of the corresponding lane, the start position flag for the lane is turned on, and the data value “1” is set in the register. On the other hand, when the strip content C is not arranged at the start position of the corresponding lane, the start position flag for the lane is turned off, and the data value “0” is set in the register. Therefore, it can be seen that when the data value “1” is set in all the registers, the strip-shaped content C is arranged at the start position of all the lanes.

  Similarly, the reference position flag 52c includes a register having the same number of bits as the total number of lanes. Each bit corresponds to each lane. When the head position P of the main keyword included in the strip content C reaches the reference position Q of the corresponding lane, the reference position flag for the lane is turned on, and the data value “1” is set in the register. On the other hand, when the leading position P of the main keyword included in the strip content C has not reached the reference position Q of the corresponding lane or when the movement of the strip content C is resumed from the reference position Q toward the upper end of the screen. The reference position flag for the lane is turned off, and the data value “0” is set in the register. Accordingly, it can be seen that when the data value “1” is set in all the registers constituting the reference position flag 52c, the main keywords included in the belt-like content C of all the lanes are aligned at the reference position Q.

  The specific processing of the CPU 20 will be described. However, since only part of the content presentation processing of the above-described embodiment described with reference to FIGS. 11 and 12 is different, the different parts will be illustrated and described in detail. To do.

  As shown in FIG. 14, when the content is arranged at the start position in step S1, the start position flag for the lane is turned on in step S51. In the next step S53, it is determined whether the start position flags of all lanes are on. That is, the CPU 20 determines whether or not the data value “1” is set in all the bits of the register constituting the start position flag 52b.

  However, when the number of strip-shaped contents C to be displayed is smaller than the total number of lanes and some lanes are used, in step S53, it is determined whether the start position flags for all of the some lanes are on. to decide. The same applies to a reference position flag described later.

  If “NO” in the step S53, that is, if the data value “0” is set in any one bit, the process returns to the same step S53. On the other hand, if “YES” in the step S53, that is, if the data value “1” is set in all the bits, the start position flag of the lane is turned off in a step S55, and the process proceeds to the step S3. So that the content moves at the initial speed.

  Also, as shown in FIG. 15, it is determined in step S25 whether or not the content of the lane has reached the reference position Q. If “YES”, the movement of the content is stopped in step S61. In the next step S63, the reference position flag of the lane is turned on. In step S65, it is determined whether the reference position flags for all lanes are on. That is, the CPU 20 determines whether or not the data value “1” is set in all the bits of the register constituting the reference position flag 52c.

  If “NO” in the step S65, that is, if the data value “0” is set in any one bit, the process returns to the step S65 as it is. On the other hand, if “YES” in the step S65, that is, if the data value “1” is set in all bits, the reference position flag of the lane is turned off in a step S67, and the process proceeds to the step S29.

  According to another embodiment, the movement start at the start position of the belt-shaped content is aligned in all lanes, and the main keyword is aligned in all lanes in the reference position, and the movement start from the reference position is also aligned in all lanes. Similar to the above-described embodiment, it is excellent in intuitive grasping of information centered on keywords.

  In this embodiment, not only the start of movement at the start position of the belt-like content is aligned for all lanes, but also the main keyword is aligned for all lanes at the reference position, and the start of movement from the reference position is also aligned for all lanes. However, only one of them may be executed.
