The direction is recognized as the + Y direction in the case of the receiving unit 41c, and the -X direction in the case of the receiving unit 41d.
That is, the four receiving units 41a to 41d and the control unit 30 detect the position (direction) of the mobile terminal 2, and thus function as the terminal position detection unit of the present invention.

When recognizing the direction in which the user H exists, the control unit 30 instructs the rotation driving unit 43 to project the image projection unit 33 to project an image on the outer wall surface of the store 11 beside the passage 13 where the user H exists. At the same time as in the first embodiment, a guidance image is generated and an image is projected. Although the guidance image may be represented by an arrow as in the first embodiment, it is difficult to display a right turn or a left turn with an arrow when projected onto a wall surface, and therefore characters (for example, “straight forward”, “left turn”) , “Turn right”, etc.). In the present embodiment, it is necessary to display different guidance images depending on the direction in which the user H exists. For example, if the destination is in the + Y direction, turn right for the user H present in the + X direction, turn left for the user H present in the -X direction, and respond to the user H present in the -Y direction. In this case, it is necessary to give a direct instruction. For this reason, in addition to destination information, guidance information, and map data, the image generation unit 30b according to the present embodiment can be used by the user H (mobile terminal 2).
The image data is generated on the basis of the existence direction of the image.

As described above, according to the guidance system 1 and the guidance device 3 of the present embodiment, the user can change the projection direction of the image projection unit 33 according to the position of the mobile terminal 2, that is, the user H holding the portable terminal 2. It is possible to display the guidance image at a position where H is easy to see. In this embodiment, since the guidance image is projected onto the wall surface, it is possible to suppress the projection image from being blocked by other passersby.

Further, a DMD (registered trademark of Texas Instruments) (digital micromirror device) that modulates the light emitted from the light source by controlling the emission direction of the incident light for each micromirror as a pixel is used. You can also Further, the light source 34 is not limited to a discharge type light source lamp, and other light sources such as an LED light source composed of an LED (light emitting diode) may be used.

Instead of the image projection unit 33 of the embodiment, liquid crystal, LED (Light Emitting Diode), C
Various image display devices using RT (Cathode Ray Tube) or the like, or subtitle type or flap type display devices may be used. The guidance information notification method is not limited to image display,
For example, it is possible to instruct the direction and the like by voice, and as shown in FIG.
It is also possible to use a direction indicating device having a direction indicating member 52 fixed to one end of the motor and a driving device 53 capable of rotating the rotating shaft 51 according to guidance information (traveling direction) on the other end. is there.

Further, as shown in FIG. 12, the image projection unit 33 is configured to be rotatable by a rotation shaft extending in the direction opposite to the projection direction, and the image projection unit 33 is rotated according to the guidance information (traveling direction). The direction of the arrow may be changed by moving it. According to this, when only an arrow is displayed on the road surface as a guidance image, it is possible to point in any direction on the XY plane with one arrow image. As a result, for example, it is possible to display the guidance image with a simple structure such as an OHP (OverHead Projector).

In the embodiment, the guidance information generation unit 30a refers to the map data to identify the traveling direction along the passage 13, and displays this with an arrow, but without referring to the map data,
An arrow that directly points to the direction of the destination may be displayed.

In the embodiment, the store list L including the XY coordinates of each store 11 is stored in the storage unit 22 of the mobile terminal 2, but the store list L may be stored in the storage unit 32 of the guidance device 3. Good. In this case, if the portable terminal 2 transmits the store name as the destination information to the guidance device 3, the guidance device 3 identifies the XY coordinates of the destination by referring to the store list L, and obtains the guidance information. Generate.

In the embodiment, an arrow indicating the traveling direction is displayed as the guidance image. However, as described above, characters such as “straight ahead” may be displayed for guidance, or the current position (reference position 14) and the destination may be displayed. You may display the guide map (map) clearly indicating. Further, the convenience of the user H may be improved by displaying other images such as advertisements of the stores 11 around the reference position 14 while the guide image is not displayed or simultaneously with the guide image.
