Abstract

A system for tracking a gaze of a driver of a vehicle includes a tracking device, a processor, a memory, and a display. The tracking device is configured to track a gaze of a driver of a vehicle. The processor is in electronic communication with the tracking device. The memory is in electronic communication with the processor. The memory includes programming code configured to be executed by the processor. The programming code is configured to determine in real-time a duration of the gaze of the driver of the vehicle tracked by the tracking device. The display is in electronic communication with the processor. The display is configured to display a symbol showing the determined duration, or a portion of the determined duration, of the gaze of the driver of the vehicle as determined by the processor.

Claims

1. A system for tracking a gaze of a driver of a vehicle comprising:

a tracking device configured to track a gaze of a driver of a vehicle;

a processor in electronic communication with the tracking device;

a memory in electronic communication with the processor, the memory comprising programming code configured to be executed by the processor, the programming code configured to determine in real-time a duration of the gaze of the driver of the vehicle tracked by the tracking device, the duration comprising a total time that the driver of the vehicle gazes away from the path in which the vehicle is moving with the duration beginning when the driver initially gazes away from the path in which the vehicle is moving and the duration ending and resetting when the driver gazes back at the path in which the vehicle is moving; and

a display in electronic communication with the processor, the display configured to, as controlled by the processor, display a symbol while the vehicle is moving showing the real-time determined duration of the gaze of the driver as determined by the processor.

2. The system of claim 1 wherein the programming code is further configured to determine in real-time whether the duration exceeds a threshold of safe duration away from the path in which the vehicle is moving.

3. The system of claim 2 wherein the programming code is further configured to cause the system to alert the driver when the duration meets or exceeds said threshold.

4. The system of claim 2 wherein the programming code is further configured to cause the display to display the threshold.

5. The system of claim 1 wherein the system is configured to passively update the driver regarding the duration without changing a function of the vehicle.

6. The system of claim 1 wherein the programming code is further configured to reset the duration when the vehicle stops moving.

7. The system of claim 6 wherein the programming code is further configured to cause the memory to store all duration determinations of the processor for later viewing on the display.

8. The system of claim 2 wherein the programming code is further configured to cause the display to display a difference between the duration and the threshold.

9. The system of claim 2 further comprising an audio device, the programming code further configured to cause the audio device to state the duration or the threshold.

10. The system of claim 2 further comprising an audio device, the programming code further configured to cause the audio device to state the difference between the duration and the threshold.

11. A method of tracking a gaze of a driver of a vehicle comprising:

tracking a gaze of a driver of a vehicle with a tracking device;

determining in real-time, with a processor, a duration of the gaze of the driver of the vehicle tracked by the tracking device wherein the duration comprises a total time that the driver of the vehicle gazes away from the path in which the vehicle is moving with the duration beginning when the driver initially gazes away from the path in which the vehicle is moving and the duration ending and resetting when the driver gazes back at the path in which the vehicle is moving; and

displaying a symbol on a display, while the vehicle is moving, showing the real-time determined duration of the gaze of the driver of the vehicle tracked by the tracking device as determined by the processor.

12. The method of claim 11 further comprising the processor determining in real-time whether the duration exceeds a threshold of safe duration away from the path in which the vehicle is moving.

13. The method of claim 12 further comprising the processor causing the driver to be alerted when the duration meets or exceeds said threshold.

14. The method of claim 12 further comprising the processor causing the display to display the threshold.

15. The method of claim 11 further comprising the processor causing the driver to be passively updated regarding the duration without changing a function of the vehicle.

16. The method of claim 11 further comprising the processor resetting the duration when the vehicle stops moving.

17. The method of claim 16 further comprising the processor causing a memory to store all duration determinations of the processor for later viewing on the display.

18. The method of claim 12 further comprising the processor causing the display to display a difference between the duration and the threshold.

19. The method of claim 12 further comprising the processor causing an audio device to state the duration or the threshold.

20. The method of claim 12 further comprising the processor causing an audio device to state the difference between the duration and the threshold.
