Adaptive vision enhancement for drivers with left-right disparities of eyesight
An automotive transportation vehicle has a passenger cabin with a plurality of seating positions for respective persons to be seated. A display system in the vehicle has a plurality of display zones, wherein each display zone is visualizable along respective vectors from one or more of the seating positions. A dominant eye is identified for a particular occupant seated in a respective seating position when there is a differential vision preference between a right eye and a left eye of the particular occupant. Display content is generated to be displayed to the particular occupant. A display zone is selected for displaying the display content wherein the selected display zone corresponds to a respective vector from the seating position of the particular occupant matching the dominant eye of the particular occupant.
1 . A transportation vehicle comprising:
a passenger cabin having a plurality of seating positions for respective persons to be seated;
a display system having a plurality of display zones, each display zone being visualizable along respective vectors from one or more of the seating positions;
a vision classifier responsive to a particular occupant seated in a respective seating position for identifying a dominant eye for the particular occupant when there is a differential vision preference between a right eye and a left eye of the particular occupant;
a memory storing a vision profile for the particular occupant, the vision profile including the differential vision preference of the particular occupant;
an image source generating display content to be displayed to the particular occupant; and
a display manager coupled to the image source and to the display system, wherein the display manager is configured to select a display zone for displaying the display content wherein the selected display zone corresponds to a respective vector from the seating position of the particular occupant matching the dominant eye of the particular occupant.
2 . The transportation vehicle of claim 1 , wherein the display content comprises priority content for highlighting to the particular occupant.
3 . The transportation vehicle of claim 2 , wherein the priority content is comprised of vehicle operating parameters.
4 . The transportation vehicle of claim 2 , wherein the priority content is comprised of driver assistance advisories.
5 . The transportation vehicle of claim 1 , wherein the plurality of display zones are comprised of a heads-up display, separately addressable portions of a monitor screen, or a plurality of monitor screens or heads-up displays.
6 . The transportation vehicle of claim 1 , further comprising a user input coupled to the vision classifier for manual input of the differential vision preference of the particular occupant.
7 . The transportation vehicle of claim 1 , further comprising:
an occupant monitor coupled to the vision classifier and including an image sensor capturing images of the particular occupant;
wherein the vision classifier is configured for (1) tracking the right eye and the left eye of the particular occupant, (2) determining a gaze direction during operation of the transportation vehicle, and (3) identifying the dominant eye according to the gaze direction coinciding with predetermined actions of the particular occupant.
8 . The transportation vehicle of claim 1 , further comprising:
an external obstacle detector adapted to identify obstacles along a movement path of the transportation vehicle;
wherein the image source responds to the obstacle detector to generate the display content according to the identified obstacles, wherein the display content includes a graphic depiction of the identified obstacles, alert icons, or textual messages sent to the selected display zone.
9 . The transportation vehicle of claim 1 , wherein the vision classifier identifies dominant eyes for a plurality of occupants, and wherein the transportation vehicle further comprises:
a seating manager determining a seating arrangement of the plurality of occupants wherein a single display zone matches respective vectors correlating to the dominant eyes of the plurality of occupants.
10 . The transportation vehicle of claim 1 , further comprising:
a telematics module for sharing the vision profile with another transportation vehicle.
11 . A method of controlling a display system in a transportation vehicle, wherein the transportation vehicle has a passenger cabin with a plurality of seating positions for respective persons to be seated, wherein the display system has a plurality of display zones, wherein each display zone is visualizable along respective vectors from one or more of the seating positions, the method comprising the steps of:
identifying a dominant eye for a particular occupant seated in a respective seating position when there is a differential vision preference between a right eye and a left eye of the particular occupant;
storing a vision profile for the particular occupant, the vision profile including the differential vision preference of the particular occupant;
generating display content to be displayed to the particular occupant; and
selecting a display zone for displaying the display content wherein the selected display zone corresponds to a respective vector from the seating position of the particular occupant matching the dominant eye of the particular occupant.
12 . The method of claim 11 , wherein the display content comprises priority content for highlighting to the particular occupant.
13 . The method of claim 12 , wherein the priority content is comprised of vehicle operating parameters.
14 . The method of claim 12 , wherein the priority content is comprised of driver assistance advisories.
15 . The method of claim 11 , wherein the plurality of display zones are comprised of a heads-up display, separately addressable portions of a monitor screen, or a plurality of monitor screens or heads-up displays.
16 . The method of claim 11 , wherein the step of identifying a dominant eye is comprised of collecting user input of the differential vision preference of the particular occupant.
17 . The method of claim 11 , wherein the step of identifying a dominant eye is comprised of:
capturing images of the particular occupant;
tracking the right eye and the left eye of the particular occupant;
determining a gaze direction during operation of the transportation vehicle; and
identifying the dominant eye according to the gaze direction coinciding with predetermined actions of the particular occupant.
18 . The method of claim 11 , further comprising the step of using an external obstacle detector adapted to identify obstacles along a movement path of the transportation vehicle;
wherein the generated display content includes a graphic depiction of the identified obstacles, alert icons, or textual messages sent to the selected display zone.
19 . The method of claim 11 , further comprising the steps of:
identifying dominant eyes for a plurality of occupants;
determining a seating arrangement of the plurality of occupants wherein a single display zone matches respective vectors correlating to the dominant eyes of the plurality of occupants; and
informing the plurality of occupants of the seating arrangement.
20 . The method of claim 11 , further comprising the steps of:
sharing the vision profile with another transportation vehicle.
