Information provision device and information provision method
First Claim
1. An information providing device comprising:
- an image-light projection device configured to project an image light to a light transmission member so as to display a for-driver information image indicating for-driver information to be provided for a driver of a mobile object in a prescribed display area that is visually recognized by the driver through the light transmission member ahead of the mobile object in a direction of travel, the prescribed display area including;
an active-information image display area configured to display at least one active-information image indicating active information to be actively recognized by the driver, anda passive-information image display area configured to temporarily display, at a timing when a prescribed information provision is met, at least one passive-information image indicating passive information to be passively recognized by the driver,a viewpoint detector configured to detect a change of location of a viewpoint of the driver; and
a display controller configured to control the image-light projection device by vertically changing a position at which the passive-information image, which indicates an object to be detected existing around the mobile object, is displayed in the passive-information image display area according to a result of detection generated by the viewpoint detector so as to change a perception distance of the driver influenced by a motion parallax of the passive-information image according to a sensed relative distance of the object to be detected in the direction of travel,wherein the display controller is configured to control display of a plurality of the passive-information images,wherein passive-information images of the plurality with a same operational sequence are vertically changed in position by a same amount,wherein passive-information images of the plurality with different operational sequences are vertically changed in position by differing amounts,wherein the vertical change in position decreases from sooner to later operational sequences,wherein the active-information image display area is at a lower portion of the prescribed display area and is free of any passive-information images, including said passive-information image displayed in the passive-information image display area, andwherein the passive-information image display area includes a center portion and an upper portion of the prescribed display area.

Abstract
An information provision device and an information provision method. Each of the information provision device and information provision method includes projecting an image light to a light transmission member so as to display a for-driver information image, sensing a relative distance of an object to be detected existing around the mobile object in the direction of travel, detecting a location of a viewpoint of the driver, and changing a position at which an object image indicating the object to be detected is displayed according to a result of the detecting so as to change a perception distance of the driver influenced by a motion parallax of the object image according to the relative distance of the object to be detected in the direction of travel.

7. An information providing device comprising:
-
an image-light projection device configured to project an image light to a light transmission member so as to display a for-driver information image indicating for-driver information to be provided for a driver of a mobile object in a prescribed display area that is visually recognized by the driver through the light transmission member ahead of the mobile object in a direction of travel, the prescribed display area including; an active-information image display area that continues displaying an active-information image indicating active information to be actively recognized by the driver, and a passive-information image display area that temporarily displays, at a timing when a prescribed information provision condition is met, a passive-information image indicating passive information to be passively recognized by the driver, a viewpoint detector configured to detect a change of location of a viewpoint of the driver; and a display controller configured to control the image-light projection device by vertically changing a position at which the passive-information image is displayed in the passive-information image display area according to a result of detection generated by the viewpoint detector so as to make a perception distance of the driver influenced by the motion parallax of the passive-information image become longer than a perception distance of the driver of the active-information image displayed in the active-information image display area, wherein the display controller is configured to control display of a plurality of the passive-information images, wherein passive-information images of the plurality with a same operational sequence are vertically changed in position by a same amount, wherein passive-information images of the plurality with different operational sequences are vertically changed in position by differing amounts, and wherein the vertical change in position decreases from sooner to later operational sequences, wherein the active-information image display area is at a lower portion of the prescribed display area and is free of any passive-information images, including said passive-information image displayed in the passive-information image display area, and wherein the passive-information image display area includes a center portion and an upper portion of the prescribed display area. - View Dependent Claims (8, 9, 10, 11, 12, 13)

14. A method of providing information, the method comprising:
-
projecting an image light to a light transmission member so as to display a for-driver information image indicating for-driver information to be provided for a driver of a mobile object in a prescribed display area that is visually recognized by the driver through the light transmission member ahead of the mobile object in a direction of travel, thereby providing the for-driver information to the driver, the for-driver information image including a plurality of the object images, the prescribed display area including; an active-information image display area configured to display at least one active-information image indicating active information to be actively recognized by the driver, and a passive-information image display area configured to temporarily display, at a timing when a prescribed information provision is met, a plurality of passive-information images indicating passive information to be passively recognized by the driver; detecting a change of location of a viewpoint of the driver; and vertically changing a position at which the passive-information images, which indicate an object to be detected existing around the mobile object, are displayed in the passive-information image display area according to a result of the detecting so as to change a perception distance of the driver influenced by a motion parallax of the passive-information image according to a sensed relative distance of the object to be detected in the direction of travel, wherein passive-information images of the plurality with a same operational sequence are vertically changed in position by a same amount, wherein passive-information images of the plurality with different operational sequences are vertically changed in position by differing amounts, wherein the vertical change in position decreases from sooner to later operational sequences, wherein the active-information image display area is at a lower portion of the prescribed display area and is free of any passive-information images, including said passive-information image displayed in the passive-information image display area, and wherein the passive-information image display area includes a center portion and an upper portion of the prescribed display area.
