In the figure, among the LEDs 209, the lit LEDs are indicated by white circles, and the unlit LEDs are indicated by crosses in the white circles.

  The operation of the present embodiment will be described below with reference to FIGS. In the present embodiment, when the user walks to the target point, navigation is appropriately performed for the user using the mounting terminal 101 and the information terminal 102.

  First, the user selects the start of navigation from the input unit 306 of the information terminal 102. As a result, the map display processing unit 304 of the information terminal 102 uses the current position information 309 and the input information 307 regarding the departure point and the target point input by the user to map from the memory 314 around the current position of the information terminal 102. Information 315 is acquired and displayed on the display 312 as display information 313. The map display processing unit 304 indicates the current position of the information terminal 102 in the displayed map.

  Furthermore, when the user sets a target point from the map information displayed on the display 312 and the target point setting screen, the route search unit 303 searches for an optimal route to the target point. When there is no map information around the current position of the information terminal 102 in the memory 314, the map display processing unit 304 communicates with the map DB 105 via the communication unit 310 and acquires the map DB information 106.

  After starting navigation using the information terminal 102, the user wears the wearing terminal 101. When the user wears the wearing terminal 101, the wearing sensor 214 transmits wearing information 215 indicating that the wearing terminal 101 is worn by the user to the control unit 207, so that the control unit 207 provides direction indication from the illumination control unit 211. The function information 213 is obtained and transmitted to the information terminal 102 via the direction information transmission unit 208.

  When the information terminal 102 receives the direction presentation function information 213, the information terminal 102 stores the direction presentation function information 213 in the internal memory of the vector calculation unit 302 for use in conversion processing in the vector calculation unit 302 described later.

  The wearing terminal 101 starts sending the direction information 103 to the information terminal 102 via the direction information sending unit 208 after sending the direction presentation function information 213, and the wearing terminal 101 changes the direction information 103 every time the direction information 103 changes. 103 is transmitted to the information terminal 102.

  The information terminal 102 that has received the direction information 103 calculates a guide vector 504, which will be described later, from the input of the direction information 103, the route information 316, and the current position information 309 in the vector calculation unit 302. Based on the direction presentation function information 213 stored in the memory, the direction vector information 504 is converted into the direction indication information 104 through a process to be described later and output, so that the direction indication information 104 is attached via the direction indication information transmission unit 311. Send it back to 101.

  The wearing terminal 101 receives the direction instruction information 104 by the receiving unit 212 and guides the user in the route direction by using the LED 209 by a method described later.

  Next, a guidance method in the route direction by the mounting terminal 101 will be described. A user 701 in FIG. 7 uses the information terminal 102 to start navigation as described above. The user 701 is walking along the path 704 along the passage 702, and an ascending stairs 703 is located on the right front side of the user 701. During navigation of the information terminal 102, the wearing terminal 101 and the information terminal 102 always communicate to give directions to the user, which will be described later.

  In the state “a” in FIG. 7, in the field of view of the user 701, the direction of going up the stairs 703 in the right front direction is the route direction 708. Here, the vector calculation unit 302 receives the direction information 103, the route information 316, and the current position information 309, and outputs the direction instruction information 104 through processing described later. The vector calculation unit 302 includes the current position information 309 (longitude and latitude) of the information terminal 102 detected by the position detection unit 308, and the altitude 206 included in the direction information 103 received from the mounting terminal 101 via the reception unit 305. Based on the above, the line-of-sight position (longitude, latitude, altitude) of the user 701 is determined.

  Next, the vector calculation unit 302 includes the above-described line-of-sight position (longitude, latitude, altitude) of the user 701 and normal unit vector information 204 included in the direction information 103 received from the wearing terminal 101 via the receiving unit 305. Based on the above, a normal unit vector 401 that faces the direction of the normal unit vector information 204 is calculated starting from the position of the eye line (longitude, latitude, altitude) of the user 701 (see FIG. 5).

  In addition, the vector calculation unit 302 calculates the target unit vector 503 based on the above-described eye position (longitude, latitude, altitude) of the user 701 and the route information 316 output from the route search unit 303.

  Further, the vector calculation unit 302 calculates a guide vector 504 based on the normal unit vector 401 and the target unit vector 503. The vector calculation unit 302 converts the direction of the guide vector 504 into the lighting position of the LED 209 based on the number of LEDs 209 and the display pattern indicated by the direction presentation function information 213, and converts the magnitude of the guide vector 504 into the brightness of the LED 209. These are output as direction instruction information 104.

  The direction instruction information 104 is input to the illumination control unit 211 of the mounting terminal 101 via the direction instruction information transmission unit 311 of the information terminal 102 and the reception unit 212 of the mounting terminal 101, and the illumination control unit 211 controls the lighting state of the LED 209. By outputting the information 210 to the LED 209, the LEDs 209 corresponding to R1 and R2 in FIG.

  Thereby, light enters the visual field of the user 701 from the upper right direction, and the user 701 can recognize that the upper right direction into which the light is inserted is the route direction 708.

  The state b is a state in which the user 701 has advanced in the movement direction 706 from the state a. In the state b, since the front direction is a staircase in the field of view of the user 701, the LED 209 corresponding to L8, L1, R8, and R1 in FIG.

  Thereby, light enters the visual field of the user 701 from above, and the user 701 can recognize that the direction in which the light is inserted, that is, the direction of going up the stairs is the route direction 708.

  In this way, the direction of the guide vector 504 that leads the normal unit vector 401 of the wearing terminal 101 to the target unit vector 503 is indicated by the lighting of the LED 209 of the wearing terminal 101, thereby guiding the user in the route direction 502. Further, when the user turns his / her face in the light insertion direction and the normal unit vector 401 and the target unit vector 503 approach each other, the luminance of the LED 209 gradually decreases, and the user also determines the path direction 502 depending on the luminance of the LED 209. Can be recognized.

  As described above, when the lighting position of the LED 209 and the lighting brightness or the normal unit vector 401 and the target unit vector 503 coincide with each other, the light is turned off, so that it is possible to intuitively recognize the quality of the direction to be advanced. Furthermore, for example, the distance to the target point can be recognized by the information providing function based on the blinking interval and the luminescent color, such as blinking slowly when the target point is far away and blinking faster as the target point approaches. is there.

  According to this embodiment, the user can recognize information related to navigation of the information terminal 102 by light emission of a frame by using the wearing terminal 101. Furthermore, the user can secure the same visual field range as general glasses and can receive interactive direction instructions corresponding to the real world.

  Next, a second embodiment of the present invention will be described. In this embodiment, in addition to the navigation function described in the first embodiment, the user is able to make the target point or target relative to the current position of the user regardless of the way to the target point or target. Make it possible to recognize the direction.

  Hereinafter, the present embodiment will be described with reference to the drawings. Further, in the following, the same reference numerals are given to those equivalent to the previous embodiment, and the description thereof is omitted to avoid duplication.

  This embodiment differs from the first embodiment in that when the user receives navigation of the mounting terminal 101 and the information terminal 102, the mounting terminal 101 and the information terminal 102 give the user a target point or purpose. It has a function of indicating the direction of an object. In the present embodiment, this is called a direction guidance mode, and the navigation described in the first embodiment is called a route guidance mode.

  Note that, for example, a guidance mode changeover switch is displayed on the display 312 of the information terminal 102 so that the user can select the direction guidance mode and the route guidance mode as needed according to the purpose. It is assumed that the direction guidance mode and the route guidance mode can be switched by pressing through 306.

  Here, the route in the route guidance mode is a route from the starting point to the target point along the passage, and indicates the traveling direction of the passage, for example, going straight on a certain road or turning right at the end. Accordingly, in the route guidance mode, the wearing terminal 101 and the information terminal 102 indicate to the user the direction of travel of the passage at the current position of the user.

  On the other hand, in the direction guidance mode, the wearing terminal 101 and the information terminal 102 indicate to the user the relative direction of the target with respect to the current position of the user. Therefore, the direction guidance mode is different from the route guidance mode in this respect regardless of the direction of travel of the route or the passage in the direction instruction indicated by the terminal to the user.

  In the present embodiment, the terminal user goes to a certain park and assumes a case where a famous image in the park is to be discovered.

FIG. 4A illustrates the route guidance mode, and FIG. 5B illustrates the direction guidance mode.

  Reference numeral 901 denotes a user of the mounting terminal 102 and the information terminal 101. Reference numeral 902 denotes a park, and reference numeral 903 denotes an image standing in the park 902. The user 901 uses the navigation using the information terminal 102 described above, and the image 903 is the navigation target. Reference numeral 904 denotes a guide route that guides the user 901 to the entrance of the park 902 where the image 903 stands. A state c and a state d indicate the state of the user 901 on the guide route 904, respectively. In state d, the user 901 is in the park 902 site.

  Reference numeral 905 denotes a normal unit vector of the wearing terminal 101 in the state c. Reference numeral 906 denotes a route unit vector indicating the direction of the guide route 904 in the state c. Reference numeral 907 denotes a guidance vector in the route guidance mode, and the sum of the guidance vector 907 and the normal unit vector 905 is a route unit vector 906.

  Reference numeral 908 denotes a target unit vector in the direction guidance mode, which indicates the direction of the image 903 that is the target from the user 901 in the state c. Reference numeral 909 denotes a guidance vector in the direction guidance mode, and the sum of the guidance vector 909 and the normal unit vector 905 becomes a target unit vector 908.

  Reference numeral 910 denotes a normal unit vector of the wearing terminal 101 in the state d. Reference numeral 911 denotes a target unit vector, which indicates the direction from the user 901 to the target 903 in the state d. 912 is a guide vector in the state d, and the sum of the guide vector 912 and the normal unit vector 910 becomes a target unit vector 911.

  Here, assuming that the position information of the image 903 is disclosed in a guidebook or the like, the user 901 inputs the position information of the image 903 to the information terminal 102 and sets it as a target. As in the first embodiment, when the user 901 sets a target, the information terminal 102 determines a guide route 904 to the target point, and starts navigation for the user 901 to the target point.

  In the present embodiment, during the navigation, the user 901 depresses a guidance mode changeover switch displayed on the display 312 of the information terminal 102 via the input unit 306 to select a navigation mode. Two navigation modes, a route guidance mode and a direction guidance mode, can be selected as necessary.

  Next, the difference between the two navigation modes of the route guidance mode and the direction guidance mode will be described with reference to a state c in FIG. When the user 901 selects the navigation in the route guidance mode in the state c, the traveling direction of the guidance route 904 at the current position of the user is a route unit vector 906. Similar to the first embodiment, the wearing terminal 101 and the information terminal 102 determine the guidance vector 907 from the path unit vector 906, and direct the direction to the guidance vector 907 with the LED to the user 901. Therefore, the normal unit vector 905 of the user 901 is guided to the guide route 904.

On the other hand, when the user 901 selects the navigation in the direction guidance mode in the state c, the guidance vector 909 is calculated so that the normal unit vector 905 is directed to the target, so that the target is determined from the current position of the user. The direction pointing to the image 903 is the target unit vector 908. The wearing terminal 101 and the information terminal 102 perform calculation by replacing the path unit vector in the first embodiment with the target unit vector, determine the guide vector 909, and indicate the direction of the guide vector 909 so that the user 90
The direction is directed to 1. Therefore, the normal unit vector 905 of the user 901 is guided in the direction of the target unit vector 908 that points to the target image 903.

  Next, an example in which the navigation in the direction guidance mode effectively functions for the user to reach the target point will be described.

  It is assumed that the user 901 has come to the point of state d. As described above, the state d is a state in which the user 901 is in the park 902. In addition to the image 903, a plurality of images are installed in the park 902. However, even if there are a plurality of images in the visible range, the user can find the target image 903 by the direction guidance mode of the present embodiment as follows.

  First, when the user 901 enters the park 902, the user switches the navigation mode to the direction guidance mode. As described above, in navigation in the direction guidance mode, the information terminal 102 determines the target unit vector 911 based on the direction of the target image 903, and then derives the guidance vector 912 from the normal unit vector 910 and the target unit vector 911. Further, the information terminal 102 outputs the direction indication information 104 from the guidance vector 912 based on the information presentation function information 213 as described above and transmits it to the wearing terminal 101, so that the wearing terminal 101 is guided by the light emission of the LED 209. The user 901 is guided in the direction of the vector 912, and the user 901 can find the image 903 in the park 902.

  In this way, the user can easily find the target object by using the navigation in the direction guidance mode. In addition, for example, when you want to check a target that looks far away, search for a target in a place where there is nothing that can be specified as a passage such as the sea or Hirohara, or when searching for a specific baggage in a warehouse, the direction guidance mode Navigation is effective, and it is possible to find the target simply by specifying the position information (latitude, longitude, altitude) of the target.
