System to add parallax to video for augmented reality head up display

1. A head up display arrangement for a motor vehicle, comprising:

a source of a first video signal;

a driver monitor system configured to detect a location of at least a portion of a human driver of the motor vehicle;

an electronic processor communicatively coupled to the first video signal source and to the driver monitor system, the electronic processor being configured to produce a second video signal that is dependent upon the first video signal and that includes parallax information, the parallax information being based on the detected location of the portion of the driver, wherein the parallax information is dependent upon an estimate of where the portion of the human driver will be at a future point in time; and

a head up display projection device configured to produce a virtual image that is visible to the driver and that is based upon the second video signal.

2. The arrangement of claim 1 , wherein the first video signal lacks parallax information.

3. The arrangement of claim 1 , wherein the driver monitor system transmits infrared energy toward the driver and detects the infrared energy after the infrared energy has been reflected off of the driver.

4. The arrangement of claim 1 , wherein the driver monitor system is configured to detect a location of an eye of a human driver.

5. The arrangement of claim 1 , wherein the virtual image includes a plurality of zones, the parallax information being different for each of the zones.

6. The arrangement of claim 5 , wherein the second video signal is dependent upon a plurality of perceived distances between the driver and respective virtual objects in respective ones of the zones.

7. The arrangement of claim 6 , wherein a respective position of each of the virtual objects in the virtual image that is based upon the second video signal is translated relative to a corresponding position of the virtual object in a hypothetical virtual image that is based upon the first video signal.

8. The arrangement of claim 1 , wherein the parallax information is dependent upon a perceived position of the virtual image.

9. A method for presenting visual information to a human driver in a motor vehicle, the method comprising:

transmitting a first video signal;

detecting a location of at least a portion of the human driver of the motor vehicle;

predicting where the portion of the human driver will be at a future point in time;

transmitting a second video signal that is dependent upon the first video signal and that includes parallax information, the parallax information being based on the detected location of the portion of the driver and the prediction of where the portion of the human driver will be at a future point in time; and

producing a virtual image that is visible to the driver and that is based upon the second video signal.

10. The method of claim 9 , wherein the first video signal lacks parallax information.

11. The method of claim 9 , wherein the detecting step includes transmitting infrared energy toward the driver and sensing the infrared energy after the infrared energy has been reflected off of the driver.

12. The method of claim 9 , wherein the detecting step includes detecting a location of an eye of the human driver.

13. The method of claim 9 , wherein the virtual image includes a plurality of zones, the parallax information being different for each of the zones.

14. The method of claim 13 , wherein the second video signal is dependent upon a plurality of perceived distances between the driver and respective virtual objects in respective ones of the zones.

15. The method of claim 14 , wherein a respective position of each of the virtual objects in the virtual image that is based upon the second video signal is translated relative to a corresponding position of the virtual object in a hypothetical virtual image that is based upon the first video signal.

16. The method of claim 9 , wherein the parallax information is dependent upon a position of the virtual image as perceived by the driver.

17. The method of claim 9 , wherein the parallax information is dependent upon an estimate of where a portion of a head of the human driver will be at a future point in time.

18. A head up display arrangement for a motor vehicle, comprising:

a source of a first video signal;

a dichroic mirror;

a driver monitor system configured to:

emit infrared energy through the dichroic mirror such that the infrared energy is reflected off of a human driver of the motor vehicle;

receive the reflected infrared energy after the infrared energy is reflected off of a human driver; and

detect a location of at least a portion of a human driver of the motor vehicle based upon the received infrared energy;

an electronic processor communicatively coupled to the first video signal source and to the driver monitor system, the electronic processor being configured to produce a second video signal that is dependent upon the first video signal and that includes parallax information, the parallax information being based on the detected location of the portion of the driver and an estimate of where the portion of the human driver will be at a future point in time; and

a head up display projection device configured to emit a light field that is reflected off of the dichroic mirror to thereby produce a virtual image that is visible to the driver and that is based upon the second video signal.

19. The arrangement of claim 18 , wherein the first video signal lacks parallax information.

20. The arrangement of claim 18 , wherein the driver monitor system is configured to detect a location of an eye of a human driver.
