System, apparatus and associated methodology for interactively monitoring and reducing driver drowsiness
First Claim
1. A system for monitoring and reducing driver drowsiness, comprising:
- a plurality of sensors configured to sense driver position and motion;
an electronic storage unit configured to store an exercise database including a plurality of drowsiness detection exercises and a plurality of drowsiness reduction exercises;
an input/output interface configured to transmit information to a driver, and configured to receive information from the driver; and
a data processor configured toselect a drowsiness detection exercise from the exercise database,instruct the drowsiness detection exercise to the driver via the input/output interface,monitor driver performance of the instructed drowsiness detection exercise via the plurality of sensors,generate a drowsiness level by comparing the driver performance of the instructed drowsiness detection exercise to a model performance of the instructed drowsiness detection exercise, andcompare the drowsiness level to a predetermined threshold,wherein the data processor instructs a drowsiness reduction exercise to the driver at predetermined time intervals and monitors driver performance thereof, when the drowsiness level exceeds a predetermined threshold.

Abstract
A system, apparatus and associated methodology for interactively monitoring and reducing driver drowsiness use a plurality of drowsiness detection exercises to precisely detect driver drowsiness levels, and a plurality of drowsiness reduction exercises to reduce the detected drowsiness level. A plurality of sensors detect driver motion and position in order to measure driver performance of the drowsiness detection exercises and/or the drowsiness reduction exercises. The driver performance is used to compute a drowsiness level, which is then compared to a threshold. The system provides the driver with drowsiness reduction exercises at predetermined intervals when the drowsiness level is above the threshold.
