Abstract

Claims (30)

1 . A system for monitoring a driving operation in a real vehicle on a road, the system comprising:

an input configured to receive eye tracking data and pose tracking data for a present driver operating the vehicle;

a processing block configured to determine both gaze movement characteristics for the present driver from the eye tracking data and pose characteristics for the present driver from the pose tracking data; and

a determination block configured to determine characteristics indicative of diminished driver control associated with a potential pathological condition from both the determined gaze movement characteristics and the determined pose characteristics,

wherein the determination block determines diminished driver control associated with the potential pathological condition from both the determined gaze movement characteristics and the determined pose characteristics being outside stored baseline characteristic ranges derived from prerecorded gaze movement and pose characteristic data for the present driver during their use of the vehicle on the road.

2 . The system of claim 1 , wherein the gaze movement characteristics include gaze movement vectors in a time domain.

3 . The system of claim 2 , wherein the processing block is configured to generate the gaze movement vectors from changes in eye tracking data over time.

4 . The system of claim 1 , wherein the determination block includes a trained neural network for identifying characteristics outside of the stored baseline characteristic ranges.

5 . The system of claim 1 , wherein the determination block is configured to determine diminished driver control by identifying intoxication of the present driver from the determined gaze movement characteristics.

6 . The system of claim 1 , wherein:

the pose tracking data is based on deviations from stored baseline pose characteristics; and

the deviations include at least one of uncharacteristic head positions, uncharacteristic head rotation, oscillating head movements, slumped chest positions, slumped shoulder positions, unusual hand positions, unusual hand movements, and hands being held in a given zone for an extended duration.

7 . The system of claim 1 , wherein the gaze movement characteristics include a gaze of the present driver on another vehicle.

8 . The system of claim 1 , wherein the determination block is configured to generate a control signal for controlling the vehicle to trigger a safety response.

9 . A method for monitoring a driving operation of a real vehicle on a road, the method comprising:

receiving eye tracking data for a present driver operating the vehicle;

receiving pose tracking data for the present driver;

prerecording and storing baseline gaze movement characteristic ranges for the present driver derived from prerecorded gaze movement characteristic data from the eye tracking data for the present driver during their use of the vehicle;

prerecording and storing baseline pose characteristic ranges for the present driver derived from prerecorded pose characteristic data from the pose tracking data for the present driver during their use of the vehicle;

determining instant gaze movement characteristics for the present driver from instant eye tracking data;

determining instant pose characteristics for the present driver from instant pose tracking data; and

determining characteristics indicative of diminished driver control associated with a potential pathological condition from the respective instant determined gaze movement characteristics and instant determined pose characteristics being outside the respective stored baseline gaze movement and pose characteristic ranges.

10 . A non-transitory computer-readable medium comprising instructions that, when executed by a processor, implement:

receiving eye tracking data for a present driver presently operating a real vehicle on a road;

receiving pose tracking data for the present driver;

prerecording and storing baseline gaze movement characteristic ranges for the present driver derived from prerecorded gaze movement characteristic data from the eye tracking data for the present driver during their use of the vehicle;

prerecording and storing baseline pose characteristic ranges for the present driver derived from prerecorded pose characteristic data from the pose tracking data for the present driver during their use of the vehicle;

determining instant gaze movement characteristics for the present driver from instant eye tracking data;

determining instant pose characteristics for the present driver from instant pose tracking data; and

determining characteristics indicative of diminished driver control associated with a potential pathological condition from the respective instant determined gaze movement characteristics and instant determined pose characteristics being outside the respective baseline gaze movement and pose characteristic ranges.
