Systems and methods for collision avoidance

1. A method comprising:

determining, by a first sensor of a vehicle, a position of a potential obstacle to the vehicle;

determining, by a second sensor of the vehicle, a gaze angle of a user of the vehicle;

determining that a proximity of the gaze angle to the position of the potential obstacle is within a defined range;

determining that the user's facial or eye expression corresponds to a shock or distress; and

decreasing a threshold for a collision avoidance mechanism to initiate a collision avoidance.

2. The method of claim 1 , further comprising controlling a change in illumination on the potential obstacle, the controlling including highlighting the potential obstacle.

3. The method of claim 1 , further comprising controlling a change in illumination on the potential obstacle to get an attention of the user or a road user.

4. The method of claim 3 , wherein the change in illumination comprises increasing illumination on the potential obstacle.

5. The method of claim 1 , further comprising:

determining, by the second sensor, a gaze direction of the user of the vehicle, relative to a reference direction; and

determining that the user is potentially unaware of the potential obstacle, according to the gaze direction of the user and the determined position of the potential obstacle.

6. The method of claim 1 , further comprising:

determining, by the second sensor, a gaze direction of the user of the vehicle, relative to a reference direction; and

determining the user's awareness of the potential obstacle, according to the gaze direction of the user and the determined position of the potential obstacle.

7. The method of claim 1 , further comprising:

determining, by the first sensor, at least one of a range, angle or orientation of the potential obstacle relative to a reference.

8. The method of claim 7 , wherein the reference comprises at least one of: a position or orientation of the user's eye, a position or orientation of the first sensor, or a direction of the user's gaze.

9. The method of claim 1 , further comprising:

providing an outline of the potential obstacle to the user.

10. The method of claim 1 , further comprising:

adjusting the threshold for the collision avoidance mechanism to initiate the collision avoidance; and

changing an illumination on the potential obstacle, according to the adjusted threshold.

11. A system of a vehicle, the system comprising:

a first sensor configured to determine a position of a potential obstacle to the vehicle;

a second sensor configured to determine a gaze angle of a user of the vehicle; and

at least one processor configured to determine that a proximity of the gaze angle to the position of the potential obstacle is within a defined range, determine that the user's facial or eye expression corresponds to a shock or distress, and decrease a threshold for a collision avoidance mechanism to initiate a collision avoidance.

12. The system of claim 11 , wherein the at least one processor is further configured to control a change in illumination on the potential obstacle, the controlling including highlighting the potential obstacle.

13. The system of claim 11 , wherein the at least one processor is further configured to control a change in illumination on the potential obstacle to get an attention of the user or a road user.

14. The system of claim 11 , wherein:

the second sensor is further configured to determine a gaze direction of the user of the vehicle, relative to a reference direction; and

the at least one processor is further configured to determine that the user is potentially unaware of the potential obstacle, according to the gaze direction of the user and the determined position of the potential obstacle.

15. The system of claim 11 , wherein:

the second sensor is further configured to determine a gaze direction of the user of the vehicle, relative to a reference direction; and

the at least one processor is further configured to determine the user's awareness of the potential obstacle, according to the gaze direction of the user and the determined position of the potential obstacle.

16. The system of claim 11 , wherein the first sensor is further configured to determine at least one of a range, angle or orientation of the potential obstacle relative to a reference.

17. The system of claim 16 , wherein the reference comprises at least one of: a position or orientation of the user's eye, a position or orientation of the first sensor, or a direction of the user's gaze.

18. The system of claim 11 , wherein the at least one processor is further configured to provide an outline of the potential obstacle to the user.

19. The system of claim 11 , wherein the at least one processor is further configured to:

adjust the threshold for the collision avoidance mechanism to initiate the collision avoidance; and

change an illumination on the potential obstacle, according to the adjusted threshold.

20. A method comprising:

determining, by a first sensor of a vehicle, a position of a potential obstacle to the vehicle;

determining, by a second sensor of the vehicle, a gaze angle of a user of the vehicle;

determining that a proximity of the gaze angle to the position of the potential obstacle is within a defined range;
