(1. Overview)
First, a specific example of the operation and usage of the wearable terminal 100 according to the present embodiment will be described with reference to FIG. In the example of FIG. 1, the user U wears the wearable terminal 100, and a facility C <b> 1 and a facility C <b> 2 (hereinafter collectively referred to as the facility C) exist around the user U. The wearable terminal 100 worn by the user U includes a display device 110. The display device 110 displays guidance information regarding the facility C according to the direction of the user U and the distance to the facility C. At this time, considering the visual field of the user U, in some regions (for example, the upper region of the user visual field; hereinafter, the region is also referred to as the real environment visual field region), the real environment can be visually recognized without superimposing guidance information. In a partial area of the field of view (for example, a lower area of the field of view; hereinafter, this area is also referred to as a guidance display area), the display device 110 can confirm guidance information regarding the facility C.

  Thereby, the user U can confirm the guidance information according to the real environment on the wearable terminal 100 when viewing the real environment. More specifically, for example, the information on the facility C1 can be seen when facing the direction of the facility C1, and the information on the facility C2 can be seen when viewing the direction of the facility C2. As a result, the user U can grasp the fact that the facility C exists in the direction in which he / she is facing, an outline description of the facility C, and the like while comparing with the real world. Moreover, in this embodiment, the display mode of guidance information is changed according to the distance from the user U to the facility C. Details of the guide information display method will be described later with reference to FIGS. 3a, 3b, 4 and the like.

(2. Appearance of wearable terminal)
Next, a specific example of the appearance of the wearable terminal 100 will be described with reference to FIG. As shown in FIG. 2, the wearable terminal 100 according to the present embodiment is a spectacle-type terminal worn on the head of the user U, and a display for displaying information so as to cover a part of the field of view of the user U. Devices 110a and 110b (in the present embodiment, collectively referred to as display device 110) are provided.

  The wearable terminal 100 includes a display device 110, a front portion 120, temple portions 130a and 130b (hereinafter also collectively referred to as a temple portion 130), and support members 140a and 140b (hereinafter collectively referred to as a support member 140). And a cable 145. The front part 120 and the temple part 130 are mechanisms similar to normal glasses. By adding the display device 110 and the support member 140 to the mechanism of the glasses, the wearable terminal 100 processes various information. And functions such as presentation are realized.

  The display device 110 is a device having a display function for presenting information to the user U. When the wearable terminal 100 is worn, the display device 110 is positioned on the opposite side of the face of the user U across the front unit 120. As shown in FIG. 2, the display device 110 is formed integrally with the support member 140, and display control for the display device 110 is performed by a control unit included in the support member 140, for example. Note that the display device 110 may be provided so as to be rotatable with respect to the support member 140 for adjusting the display position.

  The front portion 120 includes rim portions 121a and 121b (hereinafter collectively referred to as rim portion 121), a bridge portion 123, and pad portions 125a and 125b (hereinafter collectively referred to as pad portion 125). When the wearable terminal 100 is worn by the user U, the front unit 120 is positioned in front of the user U's face.

  The rim portions 121a and 121b are members formed in a circumferential shape around the opening portions 127a and 127b (hereinafter collectively referred to as the opening portion 127). The opening 127 is provided for the user U to visually recognize the actual environment and the display content of the display device 110. A lens for correcting the visual acuity of the user U may be fitted into the opening 127. The rim parts 121 a and 121 b are adjacent to each other in the horizontal direction via the bridge part 123.

  Note that the rim portion 121 does not necessarily need to be formed in a circumferential shape. Especially when the wearable terminal 100 does not have a lens, the rim portion 121 and the bridge portion 123 do not provide the openings 127a and 127b. You may connect the temple part 130 of both sides linearly.

  In addition, when the wearable terminal 100 includes a lens, the lens may be supported by the temple portion 130 and the bridge portion 123 without the rim portion 121 being held in the front portion 120. Further, when a single lens is used, the bridge portion 123 is not necessary, and the single lens may be supported by the temple portions 130a and 130b.

  The pad portion 125 is a member for mounting the wearable terminal 100 on the face of the user U, and is fixed to the rim portion 121 and / or the bridge portion 123. When the user U wears the wearable terminal 100, the pad portion 125 supports the wearable terminal 100 on both sides of the user U's nasal bridge. The wearable terminal 100 is locked and / or supported on the face of the user U by a pad portion 125 and modern portions 131a and 131b (hereinafter also collectively referred to as a modern portion 131) included in a temple portion 130 described later. It is installed by.

  The temple part 130 is a substantially linear member provided to support the front part 120 on both sides of the face of the user U. In FIG. 2, the temple portion 130 extends from the front portion 120 in the depth direction. For convenience of carrying, the temple portion 130 may be attached to the front portion 120 so as to be rotatable. The temple part 130 has the modern part 131 as described above.

  As described above, the modern part 131 is a member for wearing the wearable terminal 100 on the face of the user U, and the modern part 131 is located on the opposite side of the temple part 130 from the front part 120 on the lower side and the inner side in the vertical direction. It is formed to draw a gentle arc. When the wearable terminal 100 is worn by the user U, the modern part 131 is locked to the upper part of the user U's ear in the vertical direction.

  The support member 140 is a member for supporting the display device 110, and the support member 140 is physically supported by the temple unit 130. In order to allow the user U to adjust the position of the display device 110, the support member 140 may be provided to be rotatable with respect to the temple portion 130. The support member 140 may have a control device, a position information acquisition device for acquiring position information by GPS (Global Positioning System), an orientation sensor for acquiring a direction, and the like.

  The support members 140a and 140b are connected to each other by a cable 145. The devices inside the support members 140a and 140b can communicate with each other via the cable 145, and the display contents of the display devices 110a and 110b can be linked by the communication.

  Note that the cable 145 is not necessarily provided independently. For example, a communication line through which each device inside the support members 140a and 140b can communicate may be embedded in the front part 120 of FIG. Alternatively, it is conceivable that the devices inside the support members 140a and 140b communicate wirelessly. In these cases, the cable 145 is not necessary.

  In the example of FIG. 2, the wearable terminal 100 is realized by adding the display device 110 and the support member 140 to the front part 120 and the temple part 130 corresponding to normal glasses. The realization method is not limited to this. For example, the display device 110 may be supported by the front portion 120, or the front portion 120, the support member 140, and the display device 110 may be integrally formed. Further, it is also conceivable to provide one opening 127 like a single-lens goggle without providing two openings like the openings 127a and 127b. Furthermore, the method for attaching the wearable terminal 100 to the user U is not necessarily based on the pad portion 125 and the modern portion 131, and a form for closely attaching the front portion 120 to the face and a shape for fixing the front portion 120 around the head. It is also possible to attach it with a strap.

(3. Specific example of user field of view when presenting guidance)
Hereinafter, a display example of guidance information on the display device 110 in the wearable terminal 100 according to the present embodiment will be described with reference to FIGS. 3a, 3b, and 4. FIG. FIGS. 3 a, 3 b, and 4 are diagrams each showing a specific example of the field of view of the user U when the wearable terminal 100 is worn.

  As shown in FIG. 3a, the visual field of the user U includes a real environment visual field area 40 where the real environment can be visually recognized through the opening 127, and guidance information 31a and 31b (hereinafter collectively referred to as guidance information 31) by the display device 110. And a guidance display area 30 in which the information is displayed. In the examples of FIGS. 3a, 3b, and 4, the guidance display area 30 is located below the real environment visual field area 40 in the vertical direction, but the present invention is not limited to this. For example, the guidance display area 30 may be located above, on the left side, or on the right side of the real environment visual field area 40. The positional relationship between the guidance display area 30 and the real environment visual field area 40 is determined according to the arrangement position of the display device 110 in the wearable terminal 100. In the following example, the case where the guidance display area 30 is located vertically below the real environment visual field area 40 will be mainly described.

  The real environment visual field area 40 is an area for the user U to visually recognize the real environment. In the examples of FIGS. 3 a, 3 b, and 4, nothing is described in the real environment visual field area 40, but actually, roads, buildings, vehicles such as automobiles and people, sky, ground, etc. The environment is visually recognized by the user U in the real environment visual field area 40.

  The guidance display area 30 is an area for the user U to visually recognize the guidance information 31 displayed by the display device 110. Here, the guidance display area 30 is a non-transmissive display area. That is, on the guidance display area 30, the user U cannot confirm the actual environment. That is, the guidance information 31 is not superimposed on the real environment.

  Here, the guidance information 31 displayed in the guidance display area 30 is information on the facility C around the user U. For example, information on the facility C within a predetermined distance such as within 2 km is displayed in the guidance display area 30 for each facility C.

  Here, the guide information 31 includes an image 33, distance information 35, and a direction display image 37. The image 33 is a photographic image showing the appearance of the facility C. In addition to the photograph of the appearance of the facility C, for example, an icon image indicating the function of the facility C such as a toilet can be used for the image 33.

  The distance information 35 is information indicating the distance from the position of the user U, that is, the user position of the wearable terminal 100 to the facility position of the facility C. The user position can be specified by, for example, the GPS function that the wearable terminal 100 has. The facility position can be specified by position information (latitude and longitude information) related to the facility C around the user position, which is sequentially acquired from, for example, a server (not shown). As the distance from the user position to the facility position, a linear distance can be used. Alternatively, it may be possible to set the travel route distance required until the user U actually arrives at the facility C via a road, a railroad, or the like.

  The direction display image 37 is an image for showing the user U the direction in which the facility C is located. When the guide information 31 is arranged so that the center of the guide information 31 in the horizontal direction substantially coincides with the direction of the facility C, a fixed image can be used as the direction display image 37.

Note that the content included in the guidance information 31 is not limited to the image 33, the distance information 35, and the direction display image 37. For example, the facility name of the facility C may be included in the guide information 31 or the distance information 35 may not be included in the guide information 31.
Here, the display position of the guidance information 31 is determined according to the distance from the user U to the facility C corresponding to each guidance information 31 and the direction of the facility C viewed from the user U.

  The position in the horizontal direction of the guidance information 31 is determined according to the direction of the facility C viewed from the user U. Specifically, the wearable terminal 100 controls the display position of the guidance information 31 so that the guidance information 31 is displayed in a straight line connecting the position of the user U and the position of the facility C. Thereby, the user U can intuitively grasp in which direction the facility C related to the displayed guidance information 31 is located.

  The vertical position of the guidance information 31 is determined according to the distance from the user U to the facility C, that is, the distance from the wearable terminal 100 to the facility C. Specifically, for example, the guidance information 31a related to the facility C1 with a short distance is displayed at a position close to the real environment visual field area 40, and the guidance information 31b about the facility C2 with a far distance is displayed at a position far from the real environment visual field area 40. To do. In the example of FIG. 3a, the guide information 31a related to the facility C1 is displayed larger than the guide information 31 related to the facility C2 farther away. In addition, it is also conceivable that the transparency of the guidance information 31a related to the facility C1 with a short distance is made lower than the transparency of the guidance information 31 related to the facility C2 with a long distance.

  With such a display method, the user U can easily grasp visually whether the distance to the facility C is near or far. Moreover, since the information of the near facility C is considered to have a higher need for reference to the user U, the guidance information 31 having a higher need for reference is arranged at a position closer to the real environment visual field area 40, so that the user U Can visually recognize the guidance information 31 without greatly moving the line of sight. That is, the convenience of the user U can be improved. Further, if all the guide information 31 is arranged in the same row in the horizontal direction, there is a possibility that the guide information 31 may not be arranged. However, by shifting the position in the vertical direction according to the distance in this way, the arrangement in the horizontal direction is possible. A margin can be given to the position.

  If the user U moves the face facing in the horizontal direction in the display state of FIG. 3a, the relative direction from the user U to the facility C changes, and accordingly the guidance information 31 in the horizontal direction is changed accordingly. The display position also moves. When the user U approaches the facility C or moves away from the facility C, the vertical display position of the guidance information 31 also gradually moves.

  When the user U changes the orientation of the face, the guidance information 31a regarding the facility C1 moves to the approximate center of the guidance display area 30 (for example, within ± 5 degrees from the center), the guidance display area 30 is displayed in FIG. Detailed information regarding the guidance information 31a is displayed as shown in FIG. In the example of FIG. 3b, the explanatory information 39 regarding the facility C1 is shown together with the image 33 of the facility C1. The description information 39 can include, for example, the facility name, distance, and description of the facility C1.

  Various methods of displaying the guidance information 31 in the guidance display area 30 are conceivable in addition to those shown in FIG. FIG. 4 is a diagram illustrating a second specific example relating to the display method of the guidance information 31. In the example of FIG. 4, the guidance display area 30 is divided into a first area 30a, a second area 30b, and a third area 30c in order from the top in the vertical direction, that is, from the side closer to the real environment visual field area 40. The first region 30a, the second region 30b, and the third region 30c are rectangular regions that extend in the horizontal direction. In addition, in the example of FIG. 4, although 3 area | regions are located in a line with the perpendicular direction, it is not restricted to this. For example, two or more regions may be provided.

The guide information 31 is arranged in one of the first area 30a, the second area 30b, and the third area 30c according to the distance to the corresponding facility C. For example, if the distance to the facility C is less than 300 m, the first region 30a is used. If the distance to the facility C is 300 m or more and less than 600 m, the second region 30b is used. If the distance to the facility C is 600 m or more, the first region 30a is used. The corresponding guidance information 31 may be arranged in the three areas 30c. In the example of FIG. 4, guidance information 31a related to the facility C1 that is 200 meters away is arranged in the first region 30a, and guidance information 31b related to the facility C2 that is 500 meters away is arranged in the second region 30b.
If the user U moves and the distance to the facility C approaches or moves away, the area in the guidance display area 30 where the corresponding guidance information 31 is displayed is also changed.
Alternatively, when the guide information 31 is displayed in the first area 30a, the guide information 31 is fixedly displayed in the vertical direction (that is, does not move in the vertical direction), and the second area 30b and the third area When the guide information 31 is displayed in 30c, the guide information 31 may be displayed so as to move smoothly in the vertical direction. That is, it is conceivable to change the display control content for each region.

  In the display examples of FIGS. 3A and 4, when the relative directions from the user U to the facility C coincide with each other, the guidance information 31 related to the facility C with the shortest distance is displayed in the real environment visual field 40. It is conceivable to determine the display position in the vertical direction, such as arranging the guidance information 31 related to the facility C having the next closest distance in the lower part, and arranging the guidance information 31 in the lower part.

  Alternatively, when the relative directions from the user U to the facility C coincide with each other, the display position in the vertical direction depends on the distance, and the transparency set for the guidance information 31 according to the distance. It is possible to change For example, by setting the transparency of the guidance information 31 related to the facility C near the distance low and setting the transparency related to the guidance information 31 related to the facility C far away, the guidance information 31 related to the facility C closer to the distance can be easily viewed. Become. When the user U selects specific guidance information 31, for example, a left / right flick operation or the like may be input to the input device.

(4. Specific examples of functional configuration)
Hereinafter, the functional configuration of the wearable terminal 100 according to the present embodiment will be described with reference to FIG. FIG. 5 is a block diagram illustrating a functional configuration of the wearable terminal 100 according to the present embodiment. Wearable terminal 100 roughly includes a control unit 150 and a database (DB) 160. The control unit 150 includes a current position acquisition unit 151, a direction acquisition unit 152, a facility position information acquisition unit 153, a relative position calculation unit 154, and a display control unit 155.

  The current position acquisition unit 151 specifies the current position of the user U wearing the wearable terminal 100. As a method for specifying the current location of the user U, for example, the current location where the user U is located is acquired as, for example, latitude and longitude by receiving radio waves sequentially transmitted from satellites constituting the GPS (Global Positioning System). It is possible to do. In addition, for example, it may be possible to specify the current position using a signal transmitted from a mobile phone base station or a wireless LAN in the vicinity.

  The direction acquisition unit 152 identifies the direction in which the user U is facing. Various means for specifying the direction can be considered. For example, it is possible to specify the direction by combining a geomagnetic sensor, an acceleration sensor, or the like.

  The facility location information acquisition unit 153 receives facility location information 161 indicating the location of the facility C, guidance information 163 related to the facility C, and the like from a server (not shown). At this time, for example, the facility location information acquisition unit 153 transmits the current location of the user U acquired by the current location acquisition unit 151 to the server, thereby the facility location information 161 and guidance related to the facility C around the user U. Only the information 163 may be acquired.

  The relative position calculation unit 154 includes the current position of the user U acquired by the current position acquisition unit 151, the direction of the user U acquired by the direction acquisition unit 152, and the facility position information 161 of the facility C acquired by the facility position information acquisition unit 153. Based on the above, the relative position to the facility position of the facility C from the position and direction of each user U is calculated. The relative position includes a direction from the current direction of the user U to the facility position of the facility C and a relative distance from the current position of the user U to the facility position of the facility C. In addition, about a relative distance, it can be set as the linear distance (Euclidean distance) from a user position to a facility position. Alternatively, for example, if the user U has route information such as roads and railways that can be passed in advance, the relative position calculation unit 154 can also calculate the necessary travel distance from the current position of the user U to the facility C. is there.

The display control unit 155 determines display contents to be displayed on the display device 110. In particular, the guide information providing unit 156 included in the display control unit 155 displays the guide information 31 in the guide display area 30. At this time, the display position where the guidance display area 30 displays the guidance information 31 is determined according to the relative position from the current position and orientation of the user U to the facility position of the facility C calculated by the relative position calculation unit 154. The specific example of the display position of the guide information 31 by the guide information providing unit 156 has been described above with reference to FIGS. 3a, 3b, and 4, and thus the description thereof is omitted here.
The DB 160 manages facility location information 161 and guidance information 163.

  The facility location information 161 is location information of the facility C expressed by latitude and longitude. As described above, for example, the facility location information acquisition unit 153 receives the information from a server (not shown) and stores it in the DB 160. Alternatively, it is also conceivable to store the facility location information 161 in the DB 160 in advance at the time of product shipment.

  The guidance information 163 is information regarding the facility C, and is used for display in the guidance display area 30, for example. The guidance information 163 can include, for example, an image 33 of the facility C, a facility name, a description, and the like.

(5. Process flow)
Hereinafter, the flow of processing of the wearable terminal 100 according to the present embodiment will be described with reference to FIG. Each processing step to be described later can be executed in any order or in parallel as long as there is no contradiction in processing contents, and other steps can be added between the processing steps. good. Further, a step described as a single step for convenience can be executed by being divided into a plurality of steps, and a step described as being divided into a plurality of steps for convenience can be executed as one step.

  First, the current position acquisition unit 151 acquires the current position of the user U by GPS or the like (S601). In addition, the direction acquisition unit 152 specifies the direction in which the user U is facing using an acceleration sensor, a geomagnetic sensor, or the like (S603).

(7. Effects of the present embodiment)
As described above, the wearable terminal 100 according to the present embodiment displays the guidance information 31 related to the facility C around the user U in the guidance display area 30 that does not show the real environment to the user U, that is, the non-transparent guidance display area 30. It has a function. At this time, the wearable terminal 100 changes the display mode of the guidance information 31 according to the relative positional relationship between the user position of the user U and the facility position of the facility C. Specifically, for example, the horizontal position of the guidance information 31 is adjusted so as to substantially match the direction of the facility C. For the position of the guidance information 31 in the vertical direction, the guidance information 31 related to the facility C having a short distance is displayed largely near the real environment visual field area 40, for example. As a result, the user U can easily grasp the positional relationship with the facility C visually, and can check information on a nearby facility C that is considered to have a high degree of reference without moving the line of sight. It is.
