Therefore, it is possible to specify different content presentation data when the user is facing the traveling direction and when the user is facing the left or right. That is, it is possible to specify content presentation data that is more suitable for the user's behavior.

  Further, the processing unit 110 determines presentation target specific angle information representing a horizontal presentation target specific angle used for specifying a content presentation target according to the orientation difference information, and presents the presentation target in a direction including the head orientation. An angle range of a specific angle may be set, and a content presentation target may be specified from facilities located within the angle range.

  Thus, it is possible to specify the presentation target specific angle information based on the difference angle, and set an angle range including the presentation target specific angle represented by the presentation target specific angle information. Then, it is possible to specify a content presentation target from facilities located within the set angle range.

  Here, the presentation target specifying angle refers to an angle used for specifying the content presentation target.

  The presentation target specific angle information is information representing the presentation target specific angle. The presentation target specific angle information may be the presentation target specific angle itself, or may be information mathematically equivalent to the presentation target specific angle. Further, the presentation target specific angle information is determined according to the orientation difference information. For example, when the absolute value of the difference angle represented by the azimuth difference information is 0 ° to 30 °, the presentation target specific angle information is set so that the presentation target specific angle is 30 °, and the absolute value of the difference angle Is 30 ° to 60 °, the presentation target specific angle information is set so that the presentation target specific angle is 50 °.

  The angle range refers to a range specified by the presentation target specific angle represented by the presentation target specific angle information.

  For example, in FIG. 5, the presentation target specific angle of the user US is set as θS with respect to the difference angle θB. At this time, the presentation target specific angle θS is set around the current position of the user US on the virtual map. Next, a range between the right boundary line RL and the left boundary line LL of the presentation target specific angle θS is specified as an angle range. And the content presentation object is specified from the facilities located within the specified angle range. In this example, when the center position of the facility (the position where the diagonal line of the graphic representing the facility intersects) is included in the range surrounded by RL and LL, the facility is considered to be included in the angle range. The same applies to the examples described later. In order to further limit the number of facilities included in the angle range, the presentation target specific angle may be set to a smaller value in advance.

  As described above, since the content presentation target is specified from the predetermined angle range, it is easier to specify the facility in which the user is interested as the content presentation target.

  In addition, when the user is facing either the left or right, one facility appears larger in the user's field of view and the facility and facility than when the user is facing the direction of travel. Similarly, the interval of appears to expand. For this reason, if the presentation target specific angle is set to a constant value, when the user turns to the left or right, the number of facilities around the user and included in the angle range is reduced. As a result, there may be a case where the facility that the user is interested in is not specified as a content presentation target even though the facility is close to the user.

  Therefore, the processing unit 110 may specify presentation target specific angle information representing a larger presentation target specific angle as the absolute value of the difference angle represented by the azimuth difference information is larger.

  Thereby, when the user is facing left or right as compared with when the user is facing in the traveling direction, it is possible to widen the angle range by setting the presentation target specific angle larger. In addition, the presentation target specific angle may be monotonously increased with respect to the difference angle or may not be monotonously increased.

  For example, as shown in FIG. 6A, when the head orientation DRH1 and the body orientation DRB1 coincide, that is, when the absolute value of the difference angle is 0 °, the presentation target specific angle is set to θS1. On the other hand, as shown in FIG. 6B, when the head orientation DRH2 and the body orientation DRB2 do not match and the absolute value of the difference angle is θB, which is larger than FIG. The target specifying angle is set to θS2, which is an angle larger than θS1.

  As described above, when the user is facing left or right, it is possible to specify content presentation targets from a larger number of facilities as compared with the case where the presentation target specifying angle is constant. . As a result, it is possible to specify a facility that the user is interested in as a content presentation target.

  Further, the processing unit 110 sets a right presentation target specific angle that is a right angle and a left presentation target specific angle that is a left angle based on the head orientation, and the head orientation is on the right side of the body orientation. If it is determined that there is, the angle range may be set so that the right presentation target specific angle is larger than the left presentation target specific angle.

  Here, the right presentation target specific angle refers to a right angle with respect to the head orientation among the presentation target specific angles. On the other hand, the left presentation target specific angle refers to an angle on the left side with respect to the head orientation among the presentation target specific angles.

  For example, as shown in FIG. 7A, when the head orientation DRH1 is on the right side of the body orientation DRB, that is, when the difference angle is θB1, the right presentation target specific angle is θSR1, the left presentation target The presentation target specific angle θS1 is set with the specific angle θSL1. θSR1 is set as an angle larger than θSL1.

  On the other hand, as shown in FIG. 7B, when the difference angle is θB2 larger than θB1, the presentation target specific angle θS2 is set with the right presentation target specific angle being θSR2 and the left presentation target specific angle being θSL2. θSR2 is an angle larger than θSL2. Further, as the difference angle θB2 is larger than θB1, the difference between θSR2 and θSL2 is also larger than the difference between θSR1 and θSL1.

  In the present embodiment, when the head orientation is on the right side of the body orientation, the angle range is set so that the right presentation target specific angle is larger than the left presentation target specific angle. When the user points the head to the right side of the body orientation, there is a high possibility that the user is interested in the facility located on the right side of the body orientation. In such a case, it is very likely that the line of sight is directed further to the right side than the head direction using the rotation of the eyeball. Therefore, although it is originally desirable to determine the angle range based on the line-of-sight direction, a large-scale device is necessary to detect the line-of-sight direction. Therefore, here, the rotation angle of the eyeball is estimated in advance, and by taking that into consideration, different values are used for the left presentation target specific angle and the right presentation target specific angle. The same reason applies when the left presentation target specific angle is larger than the right presentation target specific angle described later.

  As described above, when the user turns to the right, it is possible to set the angle range so that the facility located on the right side of the user is more easily identified as the content presentation target.

  Further, the processing unit 110 sets a right presentation target specific angle that is a right angle and a left presentation target specific angle that is a left angle based on the head orientation, and the head orientation is set on the left side of the body orientation. If it is determined that there is, the angle range may be set so that the left presentation target specific angle is larger than the right presentation target specific angle.

  Specifically, it is the same as the example described with reference to FIGS. 7A and 7B.

  As described above, when the user turns to the left, the angle range can be set so that the facility located on the left side of the user can be more easily identified as the content presentation target.

  In addition, the processing unit 110 may determine distance range information used for specifying the content presentation target according to the azimuth difference information, and specify the content presentation target from the set distance range.

  This makes it possible to set a distance range based on the difference angle. Then, it is possible to specify a content presentation target from facilities located within the set distance range.

  Here, the distance range refers to a range specified by a predetermined distance around an arbitrary point on the virtual map. The predetermined distance may or may not be constant. The predetermined distance may be a preset value or may be obtained by calculation.

  For example, as shown in FIG. 8A, when an angle range including the presentation target specific angle θS1 is set, a distance range DSA1 specified by a predetermined distance DS1 with the current location of the user US as the center is set. Think about setting. In this case, the content presentation target is specified from the facilities existing in the enclosed range by the angle range and the distance range DSA1.

  As described above, by combining the angle range and the distance range, the user's interest is strong, and it is easy to specify a facility within a certain distance from the user as a content presentation target.

  Further, the processing unit 110 may set a distance range in which the distance is shorter as the absolute value of the difference angle represented by the azimuth difference information is larger.

  As a result, when the user is facing the direction of travel compared to when the user is facing either the left or right, the distance range is set wider and the facility located at a position away from the user is specified as the content presentation target And so on. On the other hand, it is possible to avoid specifying a facility that is close to the user but is facing a different road from the road where the user is located and located at a far distance from the user as a content presentation target. It becomes possible.

  For example, as shown in FIG. 8B, consider a case where an angle range including the presentation target specific angle θS2 is set. While the absolute value of the difference angle in FIG. 8A is 0 °, the absolute value of the difference angle in FIG. 8B is θB, which is larger than the case of FIG. 8A. Therefore, the distance range DSA2 specified by DS2 is set using DS2 shorter than DS1 in FIG. 8A as the predetermined distance around the current location of user US. Then, the content presentation target is specified from the facilities existing in the enclosed range by the angle range and the distance range DSA2. Since such a facility is located in a direction in which the user US is facing and is located at a short distance from the user US, the facility is likely to be used by the user US.

  Conversely, in the case of FIG. 8A, the user US is facing the traveling direction, and it can be determined that there is no interest in the facility in the immediate vicinity of the user US. Therefore, the facility located in the traveling direction of the user US where the user US may be heading can be specified as the content presentation target.

  As described above, it is easy to specify a facility that is highly interested in the user and highly likely to be used by the user as a content presentation target.

  The storage unit 130 may store area graphic information that is information about the area graphic. Then, the processing unit 110 performs region graphic information based on the head direction information and the body direction information with respect to a virtual map in which the user position and the content presentation target position are set based on the user position information. May be specified, and the content presentation target may be specified from facilities located in the set area graphic.

  This makes it possible to specify a content presentation target from facilities located within the area graphic. Therefore, it is possible to arbitrarily change the range for specifying the content presentation target by changing the area graphic to be stored.

  Here, the region graphic means a graphic composed of a region having a predetermined area on the virtual map.

  Moreover, area | region figure information means the information showing an area | region figure. The area graphic information may be an image of the area graphic itself, coordinate data representing the vertex position of the area graphic, a mathematical expression representing the area graphic, or the like. Furthermore, the shape and size of the area graphic may be set and stored in advance, or may be obtained by calculation.

  For example, a specific example is shown in FIG. FIG. 9 shows a state in which the area graphic TF is superimposed on the virtual map when the head direction of the user US is DRH and the body direction is DRB. In this case, the content presentation target is specified from the facilities included in the TF. A specific method for setting the area graphic arrangement will be described later.

  By using area graphics as described above, it is possible to set the range for specifying the content presentation target according to the real world, and to provide an information processing system that is more practical. It becomes. Furthermore, since it is not necessary to obtain the angle range and the distance range by calculation by using the area graphic, it is possible to expect simplification of the algorithm and reduction of the processing amount.

  In addition, the processing unit 110 may set a plurality of points in the region graphic, and place and set the region graphic such that at least two of the plurality of points overlap the extension line of the head direction.

  Here, the point is a point set in the area graphic, and is a point used to determine the direction of the area graphic when the area graphic is superimposed on the virtual map.

  For example, FIG. 10 shows a state in which area graphics are arranged and set using points. In FIG. 10, points SP1 to SP3 are set in advance in the area graphic TF. In this case, the area figure TF is arranged and set so that at least two of the points SP1 to SP3 (here, SP1 and SP2) overlap with the extended line of the head direction DRH of the user US. Further, the distance from the user US to the area graphic TF may be set by an arbitrary method. In this example, as the simplest example, the distance (SPL) to the point (SP2) where the distance from the user US is the shortest among the points (SP1 and SP2) overlapping the extension line of the head direction DRH of the user US. ) Can be set in advance. In addition, there is a method of changing the distance SPL based on the head direction information of the user US. However, the method for setting the distance from the user to the area graphic is not limited to these methods.

  As described above, it is possible to place and set area graphics in an arbitrary direction in the virtual map.

  Further, in the method of specifying the content presentation target using the area graphic, it is necessary to prepare the area graphic in advance. Further, it is statistically known that there is a correlation between the difference angle represented by the azimuth difference information and the direction and distance of the facility in which the user is interested. Therefore, focusing on this point, it is desirable to determine the area graphic to be used based on statistical data regarding the difference angle, the direction of the facility, and the distance. When statistically analyzed, if the absolute value of the difference angle is small, there is a tendency to be interested in a distant facility, and if the absolute value of the difference angle is large, there is a tendency to be interested in a closer facility. I understand that there is.

  Therefore, the storage unit 130 may store information on a plurality of area figures having at least one of shape and size as area figure information. Then, the processing unit 110 obtains heading and body heading difference information based on the head heading information and body heading information, and based on the heading difference information, the area figure to be used from a plurality of area heads. A content presentation target may be specified by specifying a certain usage area graphic and arranging and setting the usage area graphic on the virtual map.

  Thereby, it becomes possible to change a use area figure according to a difference angle.

  Here, the use area graphic means an area graphic specified as the area graphic to be used from among a plurality of area figures having at least one of a shape and a size different from each other.

  Specific examples are shown in FIGS. 11A to 11C. In FIGS. 11A to 11C, the difference angles are different from θb1, θb2, and θb3, respectively, and the use area graphic is also different from TF1, TF2, and TF3. In the case of FIG. 11A, since the absolute value of the difference angle θb1 is small, the area figure TF1 is not included so as to include the facilities located in the traveling direction of the user US without including the facilities located on the left and right of the user US. Set the placement. In this case, since it is difficult to estimate a facility in which the user is interested, a region graphic having a large area among the plurality of region graphics is used. On the other hand, in the case of FIGS. 11B and 11C, since the user US is facing the right side, the area figure is included so that the facility located on the head orientation DRH2 or DRH3 side of the user US is included. Set the placement. As the absolute value of the difference angle approaches 90 °, it can be estimated that the user US is interested in a facility located on the left and right. Detailed information on facilities located in can be presented.

  As described above, it is possible to change the usage area graphic according to the difference angle, and to specify a facility more suitable for the user's interest as a content presentation target.

  In addition, facilities that the user is interested in have a high probability of being present in the traveling direction when the user is facing the traveling direction, and are further to the right of the head orientation when the user is facing the right. In addition, when the user is facing left, there is a higher probability of being on the left than the head orientation. That is, when the user is facing the traveling direction, many content presentation targets are specified from the traveling direction, and when the user is facing the right, more content is displayed from the region further to the right than the head orientation. When the presentation target is specified and the user is facing left, if more content presentation targets are identified from the area further to the left than the head orientation, the facility that matches the user's interest is selected as the content presentation target. It can be identified.

  Therefore, the processing unit 110 sets a reference line parallel to the head orientation, and when the head orientation and the body orientation match, an area figure that is line-symmetric with respect to the reference line is selected from a plurality of area figures. If the head area orientation and the body orientation do not coincide with each other, the area figure that is axisymmetric with respect to the reference line may be specified as the use area figure.

  In other words, when the head orientation and body orientation match, it can be assumed that the user is facing the direction of travel, so by specifying a line-symmetric area figure as the use area figure, the user's direction of travel It is possible to specify the content presentation target evenly from the left and right sides.

  Here, the line figure that is line-symmetric means a line figure that is line-symmetric with respect to a reference line parallel to the head direction. For example, as shown in FIG. 12A, it is a figure such as a region figure STF that is line-symmetric with respect to the reference line SL1. FIG. 9 described above is also an example in the case of using a line-symmetric area graphic.

  In addition, as described above, when the user points the head to the right side of the body orientation, there is a high possibility that the user is interested in the facility located on the right side of the body orientation. It is very likely that you are facing the right side.

  In the present embodiment, instead of using the left presentation target specific angle and the right presentation target specific angle described above, a non-axisymmetric area graphic is used as the use area graphic.

  Here, the non-axisymmetric area graphic means an area graphic that is non-symmetric with respect to a reference line parallel to the head direction. For example, as shown in FIG. 12B, it is a figure such as an area figure ASTF which is non-axisymmetric with respect to the reference line SL2. FIG. 10 described above is also an example in the case of using a non-axisymmetric area graphic. If a non-axisymmetric area graphic is used, the area of the right and left areas of the area graphic can be differentiated by simply placing the reference line on the extension line of the head direction and placing it on the virtual map. Compared to the case of using a line-symmetric area graphic, it is easy to make a difference between the area of the right area and the left area of the area graphic. Therefore, the non-axisymmetric area graphic is useful when it is necessary to change the range for specifying a facility as a content presentation target between the left side and the right side of the head orientation.

  Thereby, based on the user's head orientation information and body orientation information, it is possible to change the usage area figure and to specify a facility more suited to the user's interest as a content presentation target.

  Then, when the head orientation is on the right side of the body orientation, the processing unit 110 sets the area graphic on the virtual map so that the area of the right area with respect to the head orientation is increased, When the head orientation is on the left side of the body orientation, the area graphic may be arranged and set on the virtual map so that the area of the left area with respect to the head orientation is large.

  For example, in FIG. 10, the area graphic TF is arranged and set so that the area of ITF2 becomes larger among the area areas ITF1 and ITF2 in the area graphic TF divided based on the head orientation.

  As a result, when the head orientation and body orientation do not match, a non-axisymmetric area figure is identified as the use area figure, and when the user turns to the right, the facility located on the right side of the user presents more content An area figure can be arranged and set so that it can be easily identified as a target.

  Further, the processing unit 110 displays the area graphic so that the distance from the user position to the farthest end of the area graphic is shorter as the absolute value of the difference angle represented by the orientation difference information is larger on the virtual map. Arrangement may be set.

  Here, the farthest end of the area graphic means a point farthest from the user among arbitrary points on each side constituting the area graphic. Further, for the sake of simplifying the calculation, a point farthest from the user may be used as the farthest end portion of the area graphic among the points where the extension line of the user's head direction and the side of the area graphic intersect. . Further, the distance to the user is calculated for all arbitrary points on each side constituting the area graphic, the average value of the calculated distances is set as the distance between the user and the side, and the side with the longest distance is the maximum of the area graphic. It is good also as a far end part.

  As a specific example, FIG. 13 shows a case where the MFP, which is the point where the extended line of the head direction DRH of the user US intersects the side of the area graphic TF, is the farthest end of the area graphic. In this case, the distance from the position of the user US to the farthest end MFP of the area graphic TF is represented as UMD. In the present embodiment, the area graphic is arranged and set so that the distance UMD from the position of the user US to the farthest end MFP of the area graphic TF becomes shorter as the absolute value of the difference angle increases.

  Accordingly, it is possible to arrange and set the area graphic so as to include a position away from the user when the user is facing the traveling direction as compared to when the user is facing either the left or right.

  In addition, the storage unit 130 may store the level of detail set for each sub-region together with the region graphic information including information about the region graphic composed of a plurality of sub-regions. Then, the processing unit 110 may place and set an area graphic composed of a plurality of sub-areas in the virtual map, and specify a content presentation target from among facilities located within the area graphic set. . Further, the presentation data specifying unit 120 may specify the content presentation data based on the level of detail assigned to the sub-region to which the specified content presentation target belongs.

  Here, the sub-region refers to a graphic composed of a region having a predetermined area on the virtual map, and refers to a graphic constituting a part of the region graphic.

  The level of detail refers to a numerical value, a rank, or the like assigned to each content by a user or a system administrator in advance in order to show the details of information represented by the content.

  For example, when the content presentation target is a restaurant, examples of content to which a low level of detail is assigned include character information of a store name, an icon image indicating a store, and the like. On the other hand, examples of content to which a high level of detail is assigned include content indicating menus, prices, menu descriptions, word-of-mouth, appearance images, business hours, and the like.

  The level of detail can also be assigned to the sub-region as described above. For example, a maximum value can be assigned to a sub-region arranged and set closest to the user, and a minimum value can be assigned to a sub-region arranged and arranged farthest from the user.

  For example, FIG. 14 shows a state in which a content presentation target is specified using an area graphic TF composed of sub-areas STF1 and STF2. In this case, since the sub-region STF1 is arranged and set at a position closer to the user US than the sub-region STF2, the maximum detail is assigned to the sub-region STF1, and the smallest detail is assigned to the sub-region STF2. Degrees are assigned. Then, the content presentation target is specified from the facility in the area graphic TF, and the content presentation data is specified according to the degree of detail assigned to the sub-region to which the specified content presentation target belongs.

  This makes it possible to specify content presentation data having different levels of detail depending on the position of the content presentation target included in the area graphic.

  In addition, the processing unit 110 may obtain the body orientation information of the user based on the history of the user's position information.

  Here, the history of position information refers to user position information stored at predetermined time intervals.

  For example, with reference to the history of the user's position information by GPS, a motion vector (for example, the position at the kth time point and the (k + 1) th time point after the kth time point) indicating the traveling direction at each point of the user. Vector), and body orientation information is obtained using the moving average of the motion vectors as the body orientation.

  A specific example is shown in FIG. FIG. 15 shows how the user moves to positions USP1 to USP5. First, in the present embodiment, position information regarding user positions USP1 to USP5 is stored. Next, the user's motion vector at each point is obtained. As an example, the motion vector between USP1 and USP2 is DRM1. Similarly, motion vectors DRM2 to DRM4 are obtained, and body orientation information is obtained using the moving average value of DRM1 to DRM4 as the body orientation.

  In this way, body orientation information can be obtained based on the history of the position information of the user, and there is no need to provide an orientation sensor or the like used only for detecting the body orientation.

  Further, the processing unit 110 may obtain the body orientation information of the user based on the sensor information acquired from the wearable sensor or the first magnetic compass provided in the portable electronic device 20.

  Thereby, it becomes possible to obtain the body orientation information of the user based on the sensor information acquired from the wearable sensor or the first magnetic compass provided in the portable electronic device 20.

  In addition, the processing unit 110 may obtain the user's head orientation information based on sensor information acquired from a second magnetic compass provided in a wearable sensor worn on the user's head.

  Accordingly, it is possible to obtain the user's head orientation information based on the sensor information acquired from the second magnetic compass provided in the wearable sensor that is worn on the user's head.

  In addition, the processing unit 110 obtains the head orientation information of the user based on the sensor information acquired from the second magnetic compass provided in the wearable sensor that is worn on the user's head, and based on the head orientation information. The body orientation information may be corrected.

  Body orientation information is obtained based on sensor information acquired from a wearable sensor or a sensor provided in a portable electronic device. However, when the wearable sensor or the portable electronic device is mounted or held in a direction different from the direction assumed at the time of design with respect to the body, an error occurs in the value of the body orientation information. Therefore, the body orientation information is corrected to a correct value based on the head orientation information.

  As a result, even when the body orientation information detected by the wearable sensor or the like is incorrect, the body orientation information is corrected by the head orientation information, the error of the body orientation information is suppressed, and the content presentation data is specified. It becomes possible.

  Further, the processing unit 110 may perform correction processing of body orientation information based on the history of head orientation information.

  Here, the history of head orientation information refers to information obtained from a set of past head orientation information and a set of past head orientation information. A specific example of the set of past head orientation information includes time series data of past head orientation information within a predetermined period. A specific example of information obtained from a set of past head direction information includes a moving average value of head direction information.

  Accordingly, it is possible to use history such as time-series data of head orientation information in order to correct body orientation information.

  Moreover, the process part 110 may perform the correction process which makes body orientation information the moving average value of head orientation information.

  Statistically, when the user is walking, the moving average value of the head orientation of the user matches the body orientation. In the present embodiment, body orientation information is corrected based on this observation result. In addition, as a method of setting the body orientation information as the moving average value of the head orientation information, the difference between the moving average value of the body orientation information before correction and the moving average value of the head orientation is subtracted from the body orientation information before correction. A method of using the corrected value as corrected body orientation information may be used.

  This makes it possible to approximate the body orientation information to the moving average value of the head orientation information, suppress the error in the body orientation information, and specify the content presentation data.

  Note that the information processing system and the like of the present embodiment may be realized by a program. In this case, the information processing system according to the present embodiment is realized by a processor such as a CPU executing a program. Specifically, a program stored in the information storage medium is read, and a processor such as a CPU executes the read program. Here, an information storage medium (a computer-readable medium) stores programs, data, and the like, and functions as an optical disk (DVD, CD, etc.), HDD (hard disk drive), or memory (card type). It can be realized by memory, ROM, etc. A processor such as a CPU performs various processes of this embodiment based on a program (data) stored in the information storage medium. That is, the information storage medium includes a program (a program for causing the computer to execute the processing of each unit) for causing a computer (an apparatus including an operation unit, a processing unit, a storage unit, and an output unit) to function as each unit of the present embodiment. Remembered.
