Abstract

A sight line input apparatus includes: a display portion that displays an input item at a position where the input item is viewable from a driver seat; a setup portion that sets a virtual input region at a position displaced from a display region of the display portion toward a driving visual field of the driver, the virtual input region being associated with the input item; a detection portion that detects a sight line position of a driver; and an input controller that performs an input process in accordance with the input item associated with the virtual input region, when the sight line position is in the virtual input region set by the setup portion. When a predetermined operation of the driver is detected, the setup portion changes the virtual input region into a mode that permits the driver to gaze at the virtual input region with ease.

Claims

1. A sight line input apparatus comprising:

a display portion that displays an input item at a position where the input item is viewable from a driver seat, the input item being specified by a driver of a vehicle;

a setup portion that sets a virtual input region at a position displaced from a display region of the display portion toward a driving visual field of the driver, the virtual input region being associated with the input item displayed on the display portion and the virtual input region not being displayed;

a detection portion that detects a sight line position of the driver; and

an input controller that performs an input process in accordance with the input item associated with the virtual input region, when the sight line position detected by the detection portion is in the virtual input region set by the setup portion,

wherein;

on condition that a predetermined operation by the driver is detected, the setup portion changes the virtual input region into a mode that permits the driver to gaze at the virtual input region with ease; and

the display portion is disposed in a center member of a dashboard located in front of the driver seat, the center member being located midway between the driver seat and a passenger seat.

2. The sight line input apparatus according to claim 1, wherein:

as the predetermined operation, on condition that the sight line position detected by the detection portion is moved to a particular position, the setup portion changes the virtual input region into a mode that permits the driver to gaze at the virtual input region with ease.

3. The sight line input apparatus according to claim 1, further comprising:

an operation information acquisition portion that acquires operation information on a driving operation performed with respect to the vehicle,

wherein;

as the predetermined operation, when a particular driving operation is performed in relation to the operation information, the setup portion changes the virtual input region into a mode that permits the driver to gaze at the virtual input region with ease.

4. The sight input apparatus according to claim 1, wherein:

The setup portion enlarges the virtual input region on condition that a predetermined operation performed by the driver is detected.

5. The sight line input apparatus according to claim 1, wherein:

on condition that a predetermined operation performed by the driver is detected, the setup portion moves the virtual input region close to a reference sight line position that is set at a predetermined position in the driving visual field of the driver.

6. The sight line input apparatus according to claim 1, wherein:

the setup portion positions the virtual input region on a virtual line connecting the display region of the display portion and the reference sight line position, which is set at a predetermined position in the driving visual field of the driver.

7. The sight line input apparatus according to claim 1, wherein:

the setup portion positions the virtual input region at a position where the virtual input region includes the reference sight line position, which is set at a predetermined position in the driving visual field of the driver.

8. The sight line input apparatus according to claim 5, further comprising:

a vehicle information acquisition portion that acquires vehicle information on a traveling status of the vehicle,

wherein;

the setup portion varies the reference sight line position in accordance with the traveling status indicated by the vehicle information.

9. The sight line input apparatus according to claim 1, further comprising:

a vehicle information acquisition portion that acquires vehicle information on a traveling status of the vehicle,

wherein;

the setup portion varies, based on the traveling status indicated by the vehicle information, a degree by which the virtual input region is changed into a mode that permits the driver to gaze at the virtual input region with ease while the virtual input region is not displayed.

10. The sight line input apparatus according to claim 1, further comprising:

a presentation portion that, when the sight line position of the driver is detected in the virtual input region, presents information on the sight line position of the driver.

11. The sight line input apparatus according to claim 1, further comprising:

a feedback portion that, when the sight line position of the driver is detected in the virtual input region by the detection portion, provides a feedback indicative of detection of the sight line position in the virtual input region to the driver,

wherein;

the feedback includes a vibration generated in a steering wheel.

12. The sight line input apparatus according to claim 1, wherein the center member is a center console.

13. The sight line input apparatus according to claim 1, wherein the center member is a center panel.

14. The sight line input apparatus according to claim 1, wherein the display portion displays the input item right side up when the input item is viewed from the driver seat.

15. The sight line input apparatus according to claim 1, wherein an area in the virtual input region corresponds to an area in the display region of the display portion.
