Abstract

A system includes at least one sensor, and a computing device coupled to the at least one sensor. The computing device includes a processor, and a computer-readable storage media having computer-executable instructions embodied thereon. When executed by at least one processor, the computer-executable instructions cause the processor to identifying a dominant eye of the occupant, determine a first position associated with the dominant eye of the occupant, determine a second position associated with the occupant, and determine a first line-of-sight by extending a first line-of-sight between the first position and the second position.

Claims

1. A method of determining a field of vision associated with an occupant of a vehicle, the method comprising:

identifying a dominant eye of the occupant;

determining a first position associated with the dominant eye of the occupant;

determining a second position associated with the occupant;

determining a set of three-dimensional coordinates for each of the first position and the second position;

determining a first line-of-sight by extending a first line between the first position and the second position based on the three-dimensional coordinates for each of the first position and the second position; and

identifying an object outside the vehicle as being in the field of vision based at least partially on the first line-of-sight by extrapolating the first line-of-sight beyond the second position and outside the vehicle to the object located outside the vehicle.

2. A method in accordance with claim 1, wherein identifying a dominant eye further comprises:

detecting a first parameter associated with a first eye of the occupant;

detecting a second parameter associated with a second eye of the occupant; and

determining the dominant eye based at least partially on the first parameter and the second parameter.

3. A method in accordance with claim 1, wherein determining a first position further comprises detecting, using at least one depth-sensing camera, an eye position associated with the occupant.

4. A method in accordance with claim 1, wherein determining a second position further comprises detecting, using at least one depth-sensing camera, a hand position associated with the occupant.

5. A method in accordance with claim 1 further comprising:

identifying a change in one of the first position and the second position; and

determining a second line-of-sight based at least partially on one of the first line-of-sight and the change.

6. A method in accordance with claim 1 further comprising:

identifying a change in one of the first position and the second position; and

determining a meaning associated with the change.

7. One or more non-transitory computer-readable storage media having computer-executable instructions embodied thereon, wherein, when executed by at least one processor, the computer-executable instructions cause the processor to:

identify a dominant eye of an occupant of a vehicle;

determine a first position associated with the dominant eye of the occupant;

determine a second position associated with the occupant;

determine a set of three-dimensional coordinates for each of the first position and the second position;

determine a first line-of-sight by extending a first line between the first position and the second position based on the three-dimensional coordinates for each of the first position and the second position; and

identify an object outside the vehicle as being in a field of vision of the occupant based at least partially on the first line-of-sight by extrapolating the first line-of-sight beyond the second position and outside the vehicle to the object located outside the vehicle.

8. One or more computer-readable storage media in accordance with claim 7, wherein the computer-executable instructions further cause the processor to:

detect a first parameter associated with a first eye of the occupant;

detect a second parameter associated with a second eye of the occupant; and

determine the dominant eye based at least partially on the first parameter and the second parameter.

9. One or more computer-readable storage media in accordance with claim 7, wherein the computer-executable instructions further cause the processor to detect, using at least one depth-sensing camera, an eye position associated with the occupant.

10. One or more computer-readable storage media in accordance with claim 7, wherein the computer-executable instructions further cause the processor to detect, using at least one depth-sensing camera, a hand position associated with the occupant.

11. One or more computer-readable storage media in accordance with claim 7, wherein the computer-executable instructions further cause the processor to:

identify a change in one of the first position and the second position; and

determine a second line-of-sight based at least partially on one of the first line-of-sight and the change.

12. One or more computer-readable storage media in accordance with claim 7, wherein the computer-executable instructions further cause the processor to:

identify a change in one of the first position and the second position; and

determine a meaning associated with the change.

13. A system comprising:

at least one sensor; and

a computing device coupled to the at least one sensor, the computing device comprising a processor, and a computer-readable storage media having computer-executable instructions embodied thereon, wherein, when executed by at least one processor, the computer-executable instructions cause the processor to;

identify a dominant eye of an occupant of a vehicle;

determine a first position associated with the dominant eye of the occupant;

determine a second position associated with the occupant;

determine a set of three-dimensional coordinates for each of the first position and the second position;

determine a first line-of-sight by extending a first line between the first position and the second position based on the three-dimensional coordinates for each of the first position and the second position; and

identify an object outside the vehicle as being in a field of vision of the occupant based at least partially on the first line-of-sight by extrapolating the first line-of-sight beyond the second position and outside the vehicle to the object located outside the vehicle.

14. A system in accordance with claim 13, wherein the computer-executable instructions further cause the processor to:

detect, using the at least one sensor, a first parameter associated with a first eye of the occupant;

detect, using the at least one sensor, a second parameter associated with a second eye of the occupant; and

determine the dominant eye based at least partially on the first parameter and the second parameter.

15. A system in accordance with claim 13, wherein the computer-executable instructions further cause the processor to detect, using the at least one sensor, at least one of an eye position and a hand position associated with the occupant, wherein the at least one sensor is a depth-sensing camera.

16. A system in accordance with claim 13, wherein the computer-executable instructions further cause the processor to:

identify a change in one of the first position and the second position; and

determine a second line-of-sight based at least partially on one of the first line-of-sight and the change.

17. A system in accordance with claim 13, wherein the computer-executable instructions further cause the processor to:

identify a change in one of the first position and the second position; and

determine a meaning associated with the change.
