Description

  The present invention relates to an information providing system in which a display device is installed at a place where an unspecified number of people gather, and appropriate information is provided according to the installation position of the display device.

  Generally, in providing information to an unspecified number of people, it is effective to grasp attributes such as age and gender of people in the place and select and provide appropriate information according to the tendency.

  In view of the above-mentioned viewpoint, conventionally, there is provided means for reading the attributes of the person entering the station premises from an IC commuter pass or IC ticket over a certain period, and displaying the contents to be displayed on the screen based on the tendency of the obtained attributes. An information providing system for determining and switching has been proposed (see, for example, Patent Document 1).

  As described above, in the conventional information providing system described in Patent Document 1, effective information is obtained by grasping the tendency of attributes of a person in a certain place and appropriately switching display contents accordingly. A device to realize the provision has been made.

  By the way, when a large number of people move in a certain direction depending on the location, such as in a station yard or event venue, even if the location is the same, the attributes of the people who make up the flow depend on the direction of the people flow. It is assumed that the trend will change.

  In this case, since a person who is likely to keep an eye on the information displayed on a certain screen is a person who constitutes a human flow that faces the screen, the information displayed on the screen is correct on the screen. It is effective to determine according to the tendency of human flow attributes.

  However, in the above-described conventional system, although the display content is determined based on the tendency of the attributes of the person in a certain place, there is a possibility that the desired display content is not necessarily selected when the direction of human flow is not taken into consideration. There is.

In addition, when displaying route guidance information, a guide map that matches the viewpoint and line-of-sight direction of the person facing the display device screen according to the installation position of the display device and the screen orientation is displayed for the user. Easy-to-understand route guidance is possible.
However, for this purpose, since it is necessary to prepare a guide map for each display device in accordance with the position of the display device and the orientation of the screen, it takes a great deal of time to create the guide map.

Embodiment 1 FIG.
FIG. 1 is a block diagram showing a functional configuration of an information providing system 100 according to Embodiment 1 of the present invention.
In FIG. 1, an information providing system 100 includes a plurality of sensors S1, S2, S3, a plurality (or one) of display devices P1, P2, P3, an analysis unit 11, a display control unit 12, and a spatial information storage unit 13. And a server 10 having
The sensors S1 to S3, the display devices P1 to P3, and the server 10 are interconnected via a wired or wireless network.

The sensors S <b> 1 to S <b> 3 are installed at a plurality of points on a path where people can move, detect the passage of people at each point, and detect the number of people passing and the moving direction as sensor information.
The display devices P1 to P3 are installed in an arbitrary area on the route, and each have a plurality of (or one) screens corresponding to 1 to 3 display surfaces.
Note that, here, three cases are shown, but the number of sensors and display devices may be arbitrary, and the number of display devices may be one.

The server 10 instructs the display contents to the display devices P1 to P3 based on the sensor information from the sensors S1 to S3.
In the server 10, the spatial information storage unit 13 includes sensor arrangement information 14 indicating the positions or orientations of the sensors S <b> 1 to S <b> 3, path information 15 indicating the paths, and a screen arrangement indicating the positions or screen orientations of the display devices P <b> 1 to P <b> 3. Information 16 is stored.

In the server 10, the analysis unit 11 integrates the sensor information output from the sensors S <b> 1 to S <b> 3 based on the sensor arrangement information 14 and the route information 15 stored in the spatial information storage unit 13, thereby The number of people passing between them is estimated and acquired as the flow information M.
The display control means 12, based on the screen layout information 16 stored in the spatial information storage means 13 and the human flow information M acquired by the analysis means 11, for each attribute of the human flow facing the screens of the display devices P1 to P3, for each attribute. The number of passing people is estimated, display information is generated or selected according to the estimation result, and display instructions are given to the display devices P1 to P3.

FIG. 2 is an explanatory diagram showing an arrangement example when the information providing system 100 is installed in a passage in an imaginary shopping mall, and a two-dot chain line arrow indicates the north direction.
In FIG. 2, an intermediate point B of the north passage connecting the points A and C and an intermediate point E of the south passage connecting the points D and F are connected via a central point G.

In the north passage, a movie theater 21 exists at point A and a movie theater 22 exists at point C. In the south passage, a restaurant 31 exists at a point D, and a restaurant 32 exists at a point F.
The north side passage and the south side passage constitute a route through which people can move through the points A to F.

A display device P1 is installed at an intermediate point B in the north passage, and a display device P2 is installed at an intermediate point E in the south passage. Here, although an example in which two display devices P1 and P2 are installed is shown, only one display device or three or more display devices can be installed as necessary.
Three screens p1, p2, and p3 are arranged on the display device P1 in three directions excluding the wall surface direction. Similarly, the display device P2 has three screens on the three directions excluding the wall surface direction. p4, p5, and p6 are arranged.

A sensor S1 is installed in the passage between the point A and the intermediate point B, a sensor S2 is installed in the passage between the intermediate point B and the point C, and a passage between the point D and the intermediate point E is provided. Is provided with a sensor S3.
Here, an example is shown in which three sensors S1 to S3 are installed and the flow of people between the intermediate point E and the point F is calculated, but the sensor is located in the passage between the intermediate point E and the point F. May be additionally installed.

Each of the sensors S1 to S3 includes, for example, a light emitting element and a light receiving element embedded in the opposing wall surface of each passage, and is not shown in FIG.
In FIG. 2, the detection positions and detection directions of the sensors S1 to S3 are indicated by arrows s1, s2, and s3, and the directions of the arrows s1 to s3 indicate the positive direction of the human flow.

  Now, assuming that a movie for “family” is being shown at the movie theater 21 and a movie for “youth” is being shown at the movie theater 22, the point A and the intermediate point B before and after the start of the movie. It is assumed that there is a flow of “family” people between the two and a “young” person between point C and intermediate point B.

  Therefore, if the sensor S1 detects a strong flow of people from the point A toward the intermediate point B (in the direction of the arrow s1) in a certain time zone, the majority of the people constituting the flow of people are “family-friendly”. It can be estimated that.

  Therefore, it is effective to display “for families” information on the screen p1 of the display device P1 facing the human flow (arrow s1). In addition, since most of the people who moved from point A to point B are headed to the middle point E via the central point G in order to go to the south passage where the restaurants 31 and 32 are located, Similarly, it is effective to display “family-friendly” information on the screen p5 of the display device P2 facing the same.

  On the other hand, if the sensor S2 detects a strong human flow from the point C to the intermediate point B (in the direction of the arrow s2) in other time zones, the majority of the people who make up the human flow are “young people”. It can be estimated that there is.

  Therefore, it is effective to display “for young people” information on the screen p3 of the display device P1 facing the human flow (arrow s2). In addition, since it is considered that many people who have moved from point C to point B go to the intermediate point E via the central point G in the same manner as described above, the screen p5 of the display device P2 facing the human flow in this time zone is displayed. It is also effective to display information for "youth".

Next, a specific configuration for realizing the above information provision will be described.
First, components of the information providing system 100 will be described.
Sensors S1-S3 are comprised from the infrared sensor, the optical sensor, etc. which were installed in the wall surface etc. of the channel | path, and detect the passage and passage direction of the person in the area. The detection results are sequentially accumulated and aggregated in the analysis means 11 in the server 10 and are periodically output as human flow information M (amount of human flow: number of passing people and their direction) within a certain time until the current time.

FIG. 3 is an explanatory diagram illustrating an example of sensor information output from the sensors S1 to S3 in FIG.
In FIG. 3, for example, the sensor information output from the sensor S1 passes through 200 people in the forward direction (in the direction of the arrow s1 from the point A to the intermediate point B) during 10 minutes until 10:00, It shows that 40 people have passed in the reverse direction (direction from the intermediate point B to the point A).

The display devices P1 to P3 are configured as shown in FIG. 4, for example.
FIG. 4 is a perspective view illustrating a configuration example of the display devices P1 to P3.
In FIG. 4, each of the display devices P <b> 1 to P <b> 3 includes a quadrangular columnar case 41, three liquid crystal displays 42 incorporated in the case 41, and a terminal control device 43.

When one surface of the housing 41 is placed in contact with the wall surface, each screen (for example, screens p1 to p3 in FIG. 2) of the liquid crystal display 42 can be directed in three directions excluding the wall surface direction.
The terminal control device 43 manages communication between the display devices P1 to P3 and the server 10 via a wired or wireless network, and performs processing for displaying instruction information from the server 10 on the screen of each liquid crystal display 42.

The spatial information storage means 13 in the server 10 indicates sensor arrangement information 14 indicating the positions or orientations of the sensors S1 to S3, route information 15 indicating a person's movement route, and the positions or screen orientations of the display devices P1 to P3. The screen layout information 16 shown is stored.
The function of the spatial information storage unit 13 is realized by a storage device and a processing device that are components of the server 10 and software that operates on the server 10.

FIG. 5 is an explanatory diagram showing a specific example of the route information 15, FIG. 5A shows an example of the route information 15, and FIG. 5B shows an expression example of the route information 15.
In FIG. 5A, the route information 15 has a graph structure in which the points A to F are nodes, and the route between the points (sections # 1 to # 6) is an arc (see an arrow). Here, the direction of the arc (arrow) indicates the positive direction.

  In general, in a shopping center or the like, a person moves in either the positive direction or the negative direction, and it is important to determine which direction the person is moving. ) Define the positive and negative directions as indicated by the arrows in).

  In FIG.5 (b), the route information 15 consists of a table format, the table | surface (refer upper stage) which described the point name AF and the X coordinate and Y coordinate of each point, and every area # 1- # 6. It is expressed by a table (see the lower row) in which the names of the start and end points and the directions (east, west, south, and north) of each route are described.

FIG. 6 is an explanatory diagram showing an example of the sensor arrangement information 14.
In FIG. 6, the sensor arrangement information 14 has a table format and is expressed by a table in which sensor numbers # S1 to # S3, sections targeted by the sensors S1 to S3 and directions (front and rear) of the sensors are described. ing.

  Here, when the direction of the sensor is “front”, the sensor information is output with the positive direction of the target section as the forward direction and the negative direction as the reverse direction. On the other hand, when the direction of the sensor is “rear”, sensor information is output with the negative direction of the target section as the forward direction and the positive direction as the reverse direction.

FIG. 7 is an explanatory diagram showing an example of the screen layout information 16.
In FIG. 7, the screen layout information 16 has a table format, and is represented by a table in which screen numbers # p1 to # p6 and positions and orientations (east, west, north, and south) of the screens p1 to p6 are described.

The analysis unit 11 in the server 10 integrates each sensor information from the plurality of sensors S1 to S3 and performs an analysis process, and outputs the amount of human flow between the points as human flow information M.
FIG. 8 shows the processing of the analysis means 11, FIG. 8 (a) is a flowchart showing the procedure of the analysis processing, and FIG. 8 (b) is a formula for calculating the number of passing people when joining from the adjacent section to the target section. It is explanatory drawing which shows.

The analysis process by the analysis unit 11 is a process for estimating the number of passing people per unit time in the positive direction and the negative direction of each section constituting the route.
This process repeats the processes of steps 113 and 115 in FIG. 8A for each section, and ends when the estimated values are determined for all the sections.

In FIG. 8A, the analysis unit 11 first selects a target section (step 111), and determines whether or not the processing of all sections has been completed (step 112).
If it is determined in step 112 that the processing for all sections has been completed (ie, yes), the analysis processing in FIG. 8A is terminated.

On the other hand, if it is determined in step 112 that the processing for all the sections has not been completed (ie, no), the number of passing persons is estimated based on the sensor information from the sensors installed in the target section (step 113). .
That is, it is determined from the sensor arrangement information 14 whether or not there is a sensor for the target section, and if it exists, the number of passing people per unit time is calculated from the sensor information.

Next, it is determined whether or not the analysis processing of the target section has succeeded (step 114). If it is determined to be successful (that is, yes), the process returns to step 111 to select the next target section.
On the other hand, if it is determined in step 114 that the analysis process of the target section is unsuccessful (that is, no), an estimation process based on the passing person estimation result in the adjacent section is performed (step 115).

That is, it is determined from the route information 15 whether or not the number of people passing through the target section can be derived from the number of people passing through the adjacent section. The number of people passing through the target section is calculated, and the process returns to step 111.
For example, in FIG. 8B, when other adjacent sections a and b merge with the target section c, the passing number Nc of the target section c is obtained as in the following formula (1).

    Nc = Na + Nb (1)

However, in Formula (1), as a general formula, the number of people passing through an arbitrary section k (k = a, b, c,...) Is indicated by Nk, and Na and Nb are passing through other sections a and b. It is the number of people.
Similarly, if only one of the numbers Na, Nb, and Nc has not been calculated and the other two have been calculated, the number of people passing can be estimated by applying equation (1). it can.

FIG. 9 is an explanatory diagram showing an example of the human flow information M generated from the analysis means 11.
In FIG. 9, the data in the section # 1 is human flow information M between the point A and the intermediate point B. Further, according to the sensor arrangement information 14, the human flow in the section # 1 is detected by the sensor S1.

Based on the sensor information from the sensor S1, the analysis means 11 has 200 people / 10 minutes (20 people / minute) in the positive direction (forward direction) and 40 people in the negative direction (reverse direction) as the number of passing people per unit time. / 10 minutes (4 people / minute).
Similarly, the human flow information M in the sections # 2 and # 4 can be calculated based on the sensor information from the sensors S2 and S3, respectively.

  The data for section # 3 is the human flow information M between the intermediate point B and the central point G, and the data for the section # 4 is human flow information M between the central point G and the intermediate point E. No sensors are installed in sections # 3 and # 4.

  However, it can be seen from the route information 15 that the human flow in the sections # 3 and # 4 is the sum of the human flow in the section # 1 and the human flow in the section # 2. Therefore, the data of the section # 3 can be calculated by adding the data of the sections # 1 and # 2.

  Similarly, since the human flow in the section # 6 where the sensor is not installed is obtained by subtracting the human flow in the section # 5 from the human flow in the section # 4 from the route information 15, the passage of the section # 5 from the passing number in the section # 4. By subtracting the number of people, the number of people passing through section # 6 can be calculated.

  Based on the screen layout information 16 and the human flow information M, the display control means 12 in the server 10 estimates the passing number of people having a predetermined attribute in the human flow facing the display devices P1 to P3, and according to the estimation result. The display contents are determined, and display instructions are given to the display devices P1 to P3.

FIG. 10 is a flowchart showing display content determination processing by the display control means 12.
In FIG. 10, the display control means 12 first performs the process of estimating the number of people passing for each attribute based on the person flow information M (step 121).
Specifically, there are direct passing number estimation processing and passing number estimation processing based on the passing number of adjacent sections.

  Here, the direct estimation process of the number of passing people means that if the ratio of people with the corresponding attribute to the number of passing people is known for a certain section, the number of passing people is multiplied by this ratio to pass the attribute. This is a process for estimating the number of people.

  For example, if the person who passes the section # 2 in front of the movie theater 22 showing a “young” movie is almost a youth, assume that 100% have the attribute “youth” The number of passing people can be estimated.

  Or, after observing people passing by the camera (or visually), calculate the percentage of people judged as “young” by automatic processing (or human judgment), and multiply that percentage by the total number of people passing Thus, the number of people passing by attribute may be estimated. This attribute-specific ratio calculation process may be executed all the time during the operation period, or may be executed only once and thereafter the same numerical value may be used.

On the other hand, the passing person estimation process based on the passing person number in the adjacent section is a process for estimating the passing person number in the target section based on the passing person number in the adjacent section for the section to which the direct passing person estimation is not applied. .
FIG. 11 is an explanatory diagram showing the process of estimating the number of passing people based on the number of passing people in the adjacent sections. FIG. 11 (a) shows a case where the other sections a and b join the target section c, and FIG. A case where the current is divided from the other sections d to the target sections e and f is shown.

  In FIG. 11A, when other sections a and b join the target section c, if the passing number Na (X) and Nb (X) for the attribute X of the other sections a and b are known, the target section The passing number Nc (X) for the attribute X of c is obtained as in the following equation (2).

    Nc (X) = Na (X) + Nb (X) (2)

In the formula (2), as a general formula, the number of people passing by the attribute X in an arbitrary section k (k = a, b, c,...) Is represented by Nk (X).
On the other hand, in FIG. 11A, when the other section d is divided into two target sections e and f, the passing number Nd (X) (= Ne (X) + Nf (X)) for the attribute X of the other section d is If it is known, the passing numbers Ne (X) and Nf (X) for the attribute X of the target sections e and f are obtained as in the following expressions (3) and (4).

Ne (X) = Kde (X) · Nd (X) (3)
Nf (X) = Kdf (X) · Nd (X) (4)

  However, in Expression (3), Kde (X) is a ratio of the person with the attribute X in the other section d diverts toward the section e. In Expression (4), Kdf (X) is the ratio of the other section d. This is the rate at which the person with the attribute X diverts toward the section f.

If the passing number Nd (X) for the attribute X of the other section d is known and the respective diversion ratios Kde (X) and Kdf (X) are determined as in the expressions (3) and (4), the target section The passing number Ne (X) and Nf (X) for the attribute X of e and f can be calculated.
For example, the following two methods (A) and (B) are conceivable as methods for determining the diversion ratios Kde (X) and Kdf (X).

(A) A person passing by a camera or the like is observed, and ratios Kde (X) and Kdf (X) at which an attribute X person diverts from another section d to the target sections e and f are obtained by statistics.
(B) Assuming that the ratio of the persons with attribute X to the target sections e and f from other sections d is the same as the ratio of all persons going to sections e and f regardless of the attributes, (5) The diversion ratios Kde (X) and Kdf (X) are determined by Equation (6).

Kde (X) = Ne / Nd (5)
Kdf (X) = Nf / Nd (6)

Next, the display control means 12 selects a target screen (step 122) and determines whether or not the processing for all the sections has been completed (step 123).
If it is determined in step 123 that the processing for all sections has been completed (ie, yes), the display content determination processing in FIG. 10 is terminated.

On the other hand, if it is determined in step 123 that the processing for all sections has not been completed (ie, no), display content determination processing is performed (step 124), and the process returns to step 121.
That is, for each target screen, the number of people passing by attribute of the human flow directly facing the target screen is estimated, and the display content determination rule is applied to the number of people passing by attribute to determine the display content.

FIG. 12 is an explanatory diagram illustrating an example of a display content determination rule.
In FIG. 12, the display content determination rule has a table format, and the display content (advertisement r, s) is set for each of the conditions N (R)> 10 and N (S)> 10 with the priority “1, 2”. The display content (advertisement t) is determined as the priority “3” (no condition).

  Here, as an attribute of a person, two types of attribute R and attribute S are considered, and attribute R means “family” and attribute S means “young”. Further, N (R) is the number of people who pass the attribute R per unit time, and N (S) is the number of people who pass the attribute S per unit time.

Further, the display content can be selected from three types of advertisement r, advertisement s, and advertisement t.
The advertisement r is an advertisement for “family-friendly”, the advertisement s is an advertisement for “young”, and the advertisement t is an advertisement for both “family / young”.

  In FIG. 12, if condition N (R)> 10 (the number of people who pass attribute R “family” is “10 people / minute” or more), advertisement r is displayed, and condition N (S)> 10 (attribute This means that the advertisement s is displayed when the number of S “young people” is 10 people / minute or more), and the advertisement t is displayed when there is no condition (none of the above).

Next, with reference to FIG. 13 together with FIG. 2, FIG. 5 and FIG. 10, the procedure of the display content determination process based on the display content determination rule of FIG. 12 when the screen p5 of the display device P1 is taken as an example. This will be specifically described.
First, as described above, in step 121 in FIG.

FIG. 13 is an explanatory diagram showing the number of passing people estimation results for the attributes R and S.
In FIG. 13, the number of people passing in the positive and negative directions (people / minute) of the attributes R and S for each section # 1 to # 6 is based on the flow information M (number of people passing in the positive and negative directions for each section # 1 to # 6). Presumed.
Here, it is assumed that all persons passing through the section # 1 are assumed to have the attribute R, and all persons passing through the section # 2 are assumed to be the attribute S to perform the estimation.

  The number of people passing through the sections # 3 and # 4 can be obtained by adding the number of people passing through the sections # 1 and # 2. In addition, the number of passing people in the sections # 5 and # 6 is applied by the above method (B), and the passing number in the section # 4 is proportionally distributed according to the ratio of passing people in the sections # 5 and # 6. Can be sought.

Next, using the screen layout information 16, a human flow that faces the screen p <b> 5 is determined.
As shown in FIG. 2, the screen p5 is at the intermediate point E and faces the north direction. Therefore, the human flow directly facing the screen p5 is a positive flow (forward direction) in the section # 4. I understand.

Next, the passing numbers N (R) and N (S) corresponding to the attributes R and S in the corresponding person flow are obtained.
At this time, from the estimation result of FIG. 13, the passing number N (R) of the attribute R in the positive direction in the section # 4 is calculated as “20 people / minute”, and the passing of the attribute S in the positive direction in the section # 4. The number of people N (S) is calculated as “2 persons / minute”.

Furthermore, the display content is determined by applying the display content determination rule of FIG.
In this example, the rule of the priority “1” is applied and it is determined to display the advertisement r.

Embodiment 2. FIG.
In the first embodiment (FIG. 1), a plurality of sensors S1 to S3 are installed and the analysis unit 11 and sensor arrangement information 14 are provided in the server 10, but the sensors S1 to S3 are provided as shown in FIG. The information providing system 100A in which the analyzing unit 11 and the sensor arrangement information 14 are omitted may be applied to display a guide map as shown in FIGS.

  FIG. 14 is a block diagram showing a functional configuration of an information providing system 100A according to Embodiment 2 of the present invention. Components similar to those described above (see FIG. 1) are denoted by the same reference numerals as those described above, or Is followed by “A” and detailed description is omitted.

  In FIG. 14, the information providing system 100 </ b> A includes a plurality (or one) of display devices P <b> 1 to P <b> 3 installed in an arbitrary area on the route, and a server that instructs display contents to the display devices P <b> 1 to P <b> 3. 10A, and the display devices P1 to P3 and the server 10A are connected by a wired or wireless network.

The server 10A includes display control means 12A and spatial information storage means 13A.
The spatial information storage unit 13A stores route information 15 indicating a person's movement route, and screen arrangement information 16 indicating the position of the display devices P1 to P3 or the screen orientation.
Based on the route information 15 and the screen layout information 16, the display control unit 12 </ b> A generates a guide map that matches the viewpoint and line-of-sight direction of the person facing the screen of the display devices P <b> 1 to P <b> 3.

Next, the operation of the display control means 12A in FIG. 14 will be described with reference to FIGS. 15 and 16 together with FIGS.
FIG. 15 is a flowchart showing guide map generation processing by the display control means 12A. Steps 122 and 123 are the same processing as described above (see FIG. 10).
Here, the process of generating a guide map displayed on the screen p5 of the display device P2 installed at the intermediate point E will be described by taking as an example the case where the restaurant 32 described above (see FIG. 2) is set as the destination.

In FIG. 15, the display control means 12A selects the target screen (step 122), determines whether or not the processing of all the screens is completed (step 123), and determines that the processing is not completed (ie, no). In this case, the position and orientation of the screen p5 are specified based on the screen layout information 16 stored in the spatial information storage means 13A (step 125).
At this time, according to the screen arrangement information 16 described above (FIG. 7), it can be seen that the screen p5 is at the intermediate point E and faces the north direction.

Subsequently, the display control unit 12A determines a guide route based on the route information 15 with the viewpoint of the person facing the screen as the start point and the destination as the end point (step 126).
At this time, according to the route information 15 described above (FIG. 5A), it can be seen that the position facing the screen p5 is the center point G.
Further, since the restaurant 32 as the destination is at the point F, the guide route is the center point G → the intermediate point E → the point F.

Finally, a guide map is generated using the guide route information determined in step 126 (step 127), and the process returns to step 122.
At this time, the coordinates of the center point G, the intermediate point E, and the point F constituting the guide route are expressed by a common coordinate system common to the system adopted in the spatial information storage means 13A, and the common coordinate system is The north direction (Y-axis direction) is set to be upward.

On the other hand, since the screen p5 faces the north direction, the viewpoint of the person facing the screen p5 is the center point G, and the line-of-sight direction of the person is the south direction.
FIG. 16A is an explanatory diagram showing an example of generation of a guide map when the coordinate values before conversion are used as they are, and FIG. 16B is a further direction of the guide map of FIG. It is explanatory drawing which shows the screen which displayed (bold curved arrow) visually.

  In the example of FIGS. 16A and 16B, the line-of-sight direction (traveling direction) from the current location (center point G) is downward, and display that matches the actual viewpoint position and line-of-sight direction is realized. It is not possible.

Therefore, in order to realize display matched with the actual viewpoint position and line-of-sight direction, it is necessary to convert the guide route information from the common coordinate system XY to the viewpoint coordinate system uv.
Here, the viewpoint coordinate system uv has the viewpoint position as the origin, the line-of-sight direction as the v-axis, and the right-hand direction as the u-axis.

  The conversion from the common coordinate system XY to the viewpoint coordinate system uv is performed by first translating the common coordinate system XY so that the origin of the common coordinate system XY coincides with the origin of the viewpoint coordinate system uv, and then the common coordinate system XY. The X axis may be rotated so as to coincide with the u axis of the viewpoint coordinate system. In the example of FIG. 16, the rotation angle is 180 degrees.

FIG. 16C is an explanatory diagram illustrating a guide map generation example using the guide route information obtained by the coordinate conversion into the viewpoint coordinate system uv.
In the example of FIG. 16C, the traveling direction from the current location (center point G) is displayed upward, and a guide map that matches the viewpoint and the line-of-sight direction is obtained.

  Although the guide map of FIG. 16C can be used as it is, in order to more visually convey the traveling direction, as shown in FIG. 16D, the traveling direction (thick curved arrow) is further processed. It is also effective to display.

  As described above, the information providing system 100A according to Embodiment 2 (FIGS. 14 to 16) of the present invention is a display device that is installed at an arbitrary point on a route where a person can move and displays information on a screen. P1 to P3, spatial information storage means 13A, and display control means 12A for instructing display to display devices P1 to P3.

The spatial information storage unit 13A stores route information 15 indicating a route and screen arrangement information 16 indicating the position of the display devices P1 to P3 or the screen orientation.
The display control unit 12A generates a guide map that matches the viewpoint and line-of-sight direction of the person facing the screen of the display devices P1 to P3 based on the route information 15 and the screen layout information 16 stored in the spatial information storage unit 13A. Select and instruct display on the display devices P1 to P3.

  Thus, based on the route information 15 and the screen layout information 16, the display control means 12A that generates or selects the guide map so as to match the viewpoint and the line-of-sight direction of the person facing the screen is also used to display the display device. An easy-to-understand guide map (FIGS. 16C and 16D) can be displayed as viewed from the person facing the screens P1 to P3.

  Further, the display control unit 12A converts the guide route generated by the common coordinate system XY into a coordinate system uv that converts the viewpoint and line-of-sight direction of the person facing the screen of the display device as a reference. (FIG. 16 (a) → FIG. 16 (c)), so that the guide map for each screen is obtained by only converting the coordinates of the same guide route information without generating a guide map for each screen. Can be generated.

Furthermore, in the above description, the common coordinate system XY and the viewpoint coordinate system uv have been described as a two-dimensional coordinate system. However, a three-dimensional coordinate system including coordinates in the height direction (Z axis, w axis) is used. It can also be adopted.
In this way, when a three-dimensional coordinate system is adopted, by setting the viewpoint position obliquely above the screen position, it is possible to display a bird's eye view, and to realize an easy-to-understand guide map display. it can.
