Method and apparatus for early detection of dynamic attentive states for providing an inattentive warning
First Claim
1. A method for determining an inattentive state of an operator of a vehicle and for providing information to the operator of the vehicle, the method comprising:
- obtaining, via a first camera, face images of the operator of the vehicle;
obtaining, via a second camera, images of an environment of the vehicle;
determining one or more areas of interest in the environment of the vehicle based on the images of the environment of the vehicle;
obtaining, from a relevance and priority database, relevance and priority values corresponding to the one or more areas of interest;
determining a probability of attention of the operator of the vehicle to the one or more areas of interest based on the images of the environment of the vehicle and the relevance and priority values;
determining an attention deficiency based on the determined probability of attention and eye movements of the operator of the vehicle, the eye movements being based on the face images; and
providing, via a warning/guidance device, the information to the operator of the vehicle based on the determined attention deficiency.

Abstract
A method and apparatus for determining an inattentive state of an operator of a vehicle and for providing information to the operator of the vehicle by obtaining face images of the operator of the vehicle, obtaining images of an environment of the vehicle, determining one or more areas of interest in the environment of the vehicle based on the images of the environment, obtaining, from a relevance and priority database, relevance and priority values corresponding to the one or more areas of interest, determining a probability of attention of the operator of the vehicle to the one or more areas of interest based on the images of the environment and the relevance and priority values, determining an attention deficiency based on the determined probability of attention and the face images, and providing the information to the operator of the vehicle based on the determined attention deficiency.

7. An apparatus for determining an inattentive state of an operator of a vehicle and for providing information to the operator of the vehicle, the apparatus comprising:
-
a first camera which takes face images of the operator of the vehicle; a second camera which takes images of an environment of the vehicle; a relevance and priority database storing a plurality of relevance and priority values corresponding to a plurality of areas of interest; a warning/guidance device which provides the information to the operator of the vehicle; and a controller configured to obtain, via the first camera, the face images of the operator of the vehicle; obtain, via the second camera, the images of the environment of the vehicle; determine one or more areas of interest in the environment of the vehicle based on the images of the environment of the vehicle; obtain, from the relevance and priority database, relevance and priority values corresponding to the one or more areas of interest; determine a probability of attention of the operator of the vehicle to the one or more areas of interest based on the images of the environment of the vehicle and the relevance and priority values; determine an attention deficiency based on the determined probability of attention and eye movements of the operator of the vehicle, the eye movements being based on the face images; and provide, via the warning/guidance device, the information to the operator of the vehicle based on the determined attention deficiency.

8. A non-transitory computer-readable medium storing a program that, when executed by a processor, causes the processor to perform a method for determining an inattentive state of an operator of a vehicle and for providing information to the operator of the vehicle, the method comprising:
-
obtaining, via a first camera, face images of the operator of the vehicle; obtaining, via a second camera, images of an environment of the vehicle; determining one or more areas of interest in the environment of the vehicle based on the images of the environment of the vehicle; obtaining, from a relevance and priority database, relevance and priority values corresponding to the one or more areas of interest; determining a probability of attention of the operator of the vehicle to the one or more areas of interest based on the images of the environment of the vehicle and the relevance and priority values; determining an attention deficiency based on the determined probability of attention and eye movements of the operator of the vehicle, the eye movements being based on the face images; and providing, via a warning/guidance device, the information to the operator of the vehicle based on the determined attention deficiency.
