  The route search unit 111 performs route search processing in response to an operation instruction from the user of the glasses-type device 20 or the mobile terminal 30. Specifically, the route search unit 111 identifies a departure place and a destination according to the instruction, refers to the map information in the database 120, and refers to the identified departure place (hereinafter simply referred to as “departure place”). .) To the specified destination (hereinafter simply referred to as “destination” or “target”). When the moving means is specified, a process for searching for an optimal moving route is performed by the specified moving means.

  Arbitrary methods can be adopted for the route search process. In the present embodiment, route search processing is performed by a known method. The route search unit 111 outputs route information obtained as a result of route search processing and route guidance information for guiding the route. The output route information and route guidance information is transmitted to the glasses-type device 20 and / or the mobile terminal 30.

  The current location information acquisition unit 112 acquires the current location information of the user wearing the glasses-type device 20 and carrying the portable terminal 30 from the portable terminal 30 (or from the portable terminal 30 via the glasses-type device 20). Note that the current location information of the user is information obtained based on the positioning process of the positioning unit 36 of the mobile terminal 30. Further, since the user carries the glasses-type device 20 and the mobile terminal 30, the user's current location information can be regarded as information on the current location of the glasses-type device 20.

  The direction information acquisition unit 113 refers to the map information stored in the database 120, and the purpose of the route searched by the route search unit 111 when starting from the current location indicated by the information acquired by the current location information acquisition unit 112 Specify the direction of the ground (target direction). For example, the azimuth angle of the destination when starting from the current location is specified. The direction information acquisition unit 113 outputs information on the direction of the identified destination. The output information on the direction of the destination can be transmitted to the glasses-type device 20 and / or the mobile terminal 30.

  The display control unit 114 controls at which position in the image displayable area of the glasses-type device 20 a predetermined image for indicating the direction of the destination specified by the direction information acquisition unit 113 is displayed. Specifically, the display control unit 114 changes the display in the displayable area according to the direction of the destination specified by the direction information acquisition unit 113 and the position of the image displayable area in the glasses-type device 20. A position for displaying an image for indicating the direction of the destination (hereinafter also referred to as a “destination direction indicating image”) is determined. The determined position information is transmitted to the eyeglass-type device 20 as image display control information. The image display control information is transmitted to the eyeglass device 20 continuously or whenever the direction of the destination changes.

  The position of the image displayable area in the glasses-type device 20 is the position of the displayable area as viewed from the user wearing the glasses-type device 20. As described above, in the example of the eyeglass-type device 20 shown in FIG. 2, the position of the displayable region is the upper right as viewed from the user wearing the eyeglass-type device 20, and the example of the eyeglass-type device 20 shown in FIG. Then, the position of the displayable area is the front as viewed from the user wearing the glasses-type device 20. Information on the position of the image displayable area in the glasses-type device 20 is stored in advance in the server device 20 or another external device.

  FIG. 5 is displayed in the displayable area when the displayable area is a frontal area when viewed from the user wearing the glasses-type device 20 as in the example of the eyeglass-type device 20 illustrated in FIG. An example of a destination direction indication image is shown.

  FIG. 5A shows that a columnar image 51 is displayed on the lens A (displayable area) of the glasses-type device 20. The columnar image 51 is a destination direction indication image. In this example, since the destination direction instruction image 51 is displayed at the center in the horizontal direction of the lens A (displayable area), the destination exists in the front direction as viewed from the user wearing the spectacles-type device 20. Will do.

  In the example of FIG. 5B, a columnar destination direction indication image 52 is displayed on the right side of the lens A (displayable area). Therefore, the destination exists in the right direction as viewed from the user wearing the glasses-type device 20. The more the direction of the destination is on the right side, the more the image 52 is displayed on the right side of the lens A (displayable area).

  Although not shown, if the direction of the destination is the left side when viewed from the user wearing the spectacle-type device 20, a columnar destination direction indication image 52 is displayed on the left side of the lens A (displayable area). Is displayed.

  The display position of the destination direction indication image changes according to the direction of the destination as viewed from the user wearing the glasses-type device 20. Accordingly, when the direction in which the user wearing the eyeglass-type device 20 is facing in the image display state as shown in FIG. 5B is gradually changed to the right, the display position of the image gradually increases. Move to the left. When the front direction facing the user and the direction of the destination coincide with each other, the display state as shown in FIG. 5A is obtained (that is, the destination direction indication image is displayed at the center in the horizontal direction). Is displayed). Here, the display position of the destination direction indication image displayed on the display unit 25 (displayable area) of the eyeglass-type device 20 is controlled according to the display control unit 114 determining the display position.

  The example described with reference to FIG. 5 is an example of the control of the display position of the destination direction indication image when the position of the displayable area viewed from the user wearing the spectacle-type device 20 is the front area. is there. When the position of the displayable area viewed from the user wearing the glasses-type device 20 is not the front area, the display position of the destination direction instruction image is determined according to the relative position of the image displayable area with respect to the glasses-type device 20. Make adjustments. The reason for the adjustment and details of the adjustment method will be described later.

  As described above, the display control unit 114 determines the destination region in the displayable area according to the direction of the destination specified by the direction information acquisition unit 113 and the relative position of the image displayable area with respect to the glasses-type device 20. The display position of the direction indication image is determined. As a result, since the user can intuitively grasp the direction of the destination based on the display position of the destination direction instruction image, such a function is convenient for the user who is moving toward the destination. high.

With reference to FIG. 6, various display forms of the destination direction indication image will be described.
FIG. 6A shows an example in which the object X (for example, a building) can be seen through the lens A of the eyeglass-type device 20 and the destination exists in the direction of the object X and in front of the object X. ing. In this example, the destination direction instruction image 61 is displayed on the object X at the center in the horizontal direction of the lens A (displayable area).

  In FIG. 6B, the object X can be seen through the lens A of the eyeglass-type device 20, and the destination exists in the direction of the object X and in the back of the object X (that is, a position that cannot be visually recognized from the user's current location). An example of doing this is shown. In this example, the destination direction instruction image 62 is displayed only on the upper outside of the object X.

  In this way, when the destination exists at a position that cannot be visually recognized from the current location of the user of the eyeglass-type device 20, the destination direction instruction image 62 (target of the target) is displayed only outside the upper part of the object X that shields the destination (target). By displaying at least a part of the image for indicating the direction, the user can grasp that the destination (target) exists behind the object existing in front of the eyes. In addition, when the destination exists behind the object existing in front of the eyes, the destination direction instruction image is displayed as shown in FIG. 6B. However, the destination exists behind the object. In this case, an image may be displayed on the object X as shown in FIG.

  In the above example, the destination direction indication image is a column shape, but the image can be an arbitrary shape.

  FIG. 6C shows an example where the destination direction instruction image is circular. Further, the display form of the image can be changed depending on whether or not the destination exists at a position where it cannot be visually recognized from the current location of the user. For example, when the destination (target) is present at a position where it cannot be visually recognized from the user's current location, the image X is displayed as a watermark on the object X that blocks the destination (in the figure, the outer frame of the image is indicated by a dotted line). Display). Further, when the destination exists at a position that can be visually recognized from the user's current location, the destination can be displayed without being transparent (the outer frame of the image is displayed with a solid line). When only a part of the destination can be visually recognized from the current location, the destination direction indicating image on the part where the destination cannot be visually recognized is displayed in a watermark, and the other part can be displayed without being transparent.

  FIG. 6D shows an example in which the destination direction indicating image is an arrow. In this example, an image of an arrow pointing downward from the upper part of the lens A (displayable area) is used, but the present invention is not limited to this, and an image of an arrow pointing upward from the lower part of the lens A (displayable area) may be used. Moreover, you may display so that the image of an arrow may be moved up and down.

  Although not shown, the destination direction indication image may be displayed larger or thicker as the distance from the current location of the user of the eyeglass-type device 20 to the destination is shorter. For example, the columnar image 61 of FIG. 6A may be displayed thicker as the distance from the current location to the destination is shorter. Further, as the distance from the current location to the destination is shorter, the circular image 63 in FIG. 6C may be displayed larger.

  Referring to FIGS. 7 and 8, when the displayable area is not a front area when viewed from the user wearing the spectacle-type device 20 (for example, in the case of the example of the spectacle-type device 20 shown in FIG. 2), The destination direction indication image displayed in the displayable area will be described. In FIG. 7, there is a displayable area B in the upper right area of the lens A, and the line-of-sight direction when the user wearing the spectacle-type device 20 looks at the front is the direction a. The line-of-sight direction when the line of sight is shifted to the center indicates the direction b.

  That is, in the example illustrated in FIG. 7, there is a shift between the line-of-sight direction a toward the front of the user wearing the glasses-type device 20 and the line-of-sight direction b toward the center of the displayable area B. In the case of this example, for example, when the destination direction is the front, when the destination direction instruction image is displayed at the center in the horizontal direction of the displayable area B, the user instructs the destination direction when the line of sight is shifted to the right. Since the position of the image can be confirmed, the user may misunderstand that the direction of the destination is the right direction. Therefore, when there is a deviation between the line-of-sight direction a toward the front of the user wearing the glasses-type device 20 and the line-of-sight direction b toward the center of the displayable area B, the destination direction indication is performed according to the amount of the deviation. The display position of the image may be adjusted.

  FIG. 8 shows a difference between the line-of-sight direction a toward the front of the user wearing the spectacle-type device 20 and the line-of-sight direction b toward the center of the displayable area B as shown in FIG. When D is a front, the example of a display of the destination direction indication image in which the display position was adjusted is shown. In this example, the display position of the destination direction instruction image 81 is adjusted to the left of the center of the displayable area B in the horizontal direction. That is, when the line-of-sight direction b toward the center of the displayable area B is the right direction rather than the line-of-sight direction a toward the user's front, the display position of the destination direction indicating image 81 is the horizontal center of the displayable area B Adjusted to the left. In addition, the display position of the destination direction instruction image 81 is adjusted to the left of the center in the horizontal direction of the displayable area B as the amount of rightward shift in the line-of-sight direction b toward the center of the displayable area B increases. The

  Although not shown, when the line-of-sight direction toward the center of the displayable area is the left direction rather than the line-of-sight direction toward the front of the user, the display position of the destination direction indication image is from the horizontal center of the displayable area. Adjusted to the right. In addition, the display position of the destination direction instruction image is adjusted more to the right than the horizontal center of the displayable region as the amount of leftward shift in the line-of-sight direction toward the center of the displayable region increases.

  In the above example, the display position of the destination direction instruction image is adjusted using the line-of-sight direction toward the center of the displayable area. However, the present invention is not limited to this, and the display position can be adjusted to any position in the displayable area. You may adjust using a gaze direction. Although the display position of the destination direction indication image is adjusted using the user's line-of-sight direction, the present invention is not limited to this, and the destination direction is determined according to the relative position of the image displayable area with respect to the glasses-type device 20. The display position of the instruction image may be adjusted.

  As described above, the display position of the destination direction indication image displayed in the displayable area is adjusted and determined according to the relative position of the displayable area with respect to the glasses-type device 20. As a result, even when the displayable area is not an area in front of the user wearing the glasses-type device 20, the user can intuitively determine the direction of the destination (target) by the display position of the destination direction indication image. Can be grasped. Therefore, such a function is more convenient for a user who is moving toward a destination (target).

  With reference to FIG. 9, the example of a function structure of the spectacles type device 20 which concerns on one Embodiment is demonstrated. The glasses-type device 20 includes a route search unit 211, a current location information acquisition unit 212, a direction information acquisition unit 213, an action detection unit 214, a voice recognition unit 215, and a display control unit 216 as main functional configurations.

  The route search unit 211 transmits an instruction to execute the route search process to the server device 10 in response to an operation instruction from the user of the glasses-type device 20, and the execution result of the route search process (including route guidance information). ). The instruction for executing the route search process includes, for example, information on the departure place, the destination, and the moving means. The route search process may be instructed via the mobile terminal 30, and the glasses-type device 20 may receive the route search result from the mobile terminal 30.

  The current location information acquisition unit 212 acquires current location information specified by the mobile terminal 30 from the mobile terminal 30. The acquired current location information is transmitted to the server device 10. Note that the current location information is acquired from the mobile terminal 30, but the present location information is not limited to this, and the current location information may be specified by the eyeglass-type device 20 including a positioning processing unit and performing a positioning process.

  The direction information acquisition unit 213 acquires information on the direction of the destination of the searched route when the current location indicated by the information acquired by the current location information acquisition unit 212 is the starting point. The information on the direction of the destination may be calculated based on the information on the destination in the route search process instructed by the route search unit 211 and the information on the current location acquired by the current location information acquisition unit 212. It may be acquired from the device 10.

  The action detection unit 214 detects a predetermined action of the user of the eyeglass-type device 20 in addition to the input to the operation unit 24. The predetermined action includes, for example, the blinking of the user or the movement of the predetermined hand by the user in front of the glasses-type device 20. An arbitrary method can be used as a method for detecting these predetermined actions, and for example, a conventional detection technique can be used.

  The voice recognition unit 215 recognizes a voice uttered by the user of the eyeglass-type device 20 and specifies an operation instruction from the user.

  The display control unit 216 performs various types of information such as processing result information by the eyeglass-type device 20 and information received from an external device (for example, current location information, a route search operation screen, and route search result information). Is displayed on the display unit 25 (that is, a monitor located in the vicinity of the eyes of the user of the glasses-type device 20).

  Further, the display control unit 216 receives the information on the display position of the destination direction instruction image from the server device 10 as image display control information, and displays the destination direction instruction image display unit 25 (in accordance with the control information). The display position in (displayable area) is controlled.

  In addition, although the information of the display position of the destination direction instruction image is received from the server device 10 as the image display control information, the present invention is not limited to this method, and the display control processing for determining the display position of the destination direction instruction image is performed. You may perform by the part 216. That is, the display control unit 216 determines the destination direction indication image in the displayable area according to the direction of the destination specified by the direction information acquisition unit 213 and the position of the image displayable area in the glasses-type device 20. Can be determined and controlled.
