Driver focus analyzer

1. A driver focus analyzer system comprising:

a headrest for a vehicle, wherein the headrest defines a left half side and a right half side;

a first proximity sensor positioned within the left half side of the headrest and configured to measure a left side driver distance corresponding to a position of a left side of a driver relative to the headrest;

a second proximity sensor positioned within the right half side of the headrest and configured to measure a right side driver distance corresponding to a position of a right side of the driver relative to the headrest;

an alert output device configured to generate an audio or visual output in response to an alert; and

processing circuitry configured to:

receive first sensor data from the first proximity sensor;

receive second sensor data from the second proximity sensor;

determine, based on the first sensor data, the left side driver distance between the left side of the driver and the headrest;

determine, based on the second sensor data, the right side driver distance between the right side of the driver and the headrest;

compare the left side driver distance to the right side driver distance to determine if a predetermined distance threshold is satisfied due to a head of the driver being turned from a field of view corresponding to safe operation of the vehicle, wherein the predetermined distance threshold is satisfied in an instance in which the left side driver distance is different than the right side driver distance; and

cause the alert in response to determining that the predetermined distance threshold is satisfied and a predetermined time threshold is satisfied, wherein the predetermined time threshold accounts for the driver adjusting position, the driver performing a blind spot check, or the driver looking briefly at signs or address information on a building.

2. A driver focus analyzer comprising:

a first proximity sensor positioned within a left half side of a headrest and configured to measure a left side driver distance corresponding to a posit ion of a left side of a driver relative to the headrest;

a second proximity sensor positioned within a right half side of the headrest and configured to measure a right side driver distance corresponding to a position of a right side of the driver relative to the headrest;

an alert output device configured to generate an audio or visual output in response to an alert; and

processing circuitry configured to:

receive first sensor data from the first proximity sensor;

receive second sensor data from the second proximity sensor;

determine, based on the first sensor data, the left side driver distance between the left side of the driver and the headrest;

determine, based on the second sensor data, the right side driver distance between the right side of the driver and the headrest;

determine, based on a comparison of the left side driver distance and the right side driver distance, a motion that corresponds to a head of the driver being turned from a field of view corresponding to safe operation of the vehicle;

determine if the motion satisfies a predetermined motion threshold, wherein the predetermined motion threshold is satisfied in an instance in which the left side driver distance is different than the right side driver distance; and

cause the alert in response to the motion satisfying the predetermined motion threshold and a predetermined time threshold, wherein the predetermined time threshold accounts for the driver adjusting position, the driver performing a blind spot check, or the driver looking briefly at signs or address information on a building.
