Claims:WE CLAIM
1. A method for warning a driver of a vehicle using a mobile device, the method comprising:
capturing, by at least one first camera of the mobile device, at least one facial aspect of the driver;
capturing, by at least one second camera of the mobile device, a path view visible ahead of the vehicle up to a predefined distance;
identifying using image analytics, by the mobile device, a field of view of the driver, based on the at least one facial aspect and at least one path event demanding attention of the driver, based on the path view and the field of view of the driver;
detecting, by the mobile device, absence of a driver response in response to identifying the at least one path event within the field of view of the driver;
extracting, by the mobile device, driver details associated with the driver; and
issuing, by the mobile device, a notification to the driver based on the driver details, when the absence of the driver response is detected.
2. The method of claim 1, wherein the at least one facial aspect comprises at least one of gaze direction, facial direction, or eye position.
3. The method of claim 1 further comprising determining a mobile device placement position within the vehicle to capture the at least one facial aspect and the path view visible ahead, the mobile device placement position being determined using the at least one first camera and the at least one second camera.
4. The method of claim 1 further comprising retrieving environment details associated with environment around the vehicle and vehicle details associated with the vehicle.
5. The method of claim 4, wherein the environment details are retrieved from a database or by using the at least one second camera, the environment details comprise at least one of road condition, weather condition, or traffic condition.
6. The method of claims 4, wherein the vehicle details are retrieved from a vehicle management system onboard the vehicle, the vehicle details comprise at least one of brake conditions, tire condition, tire pressure, speed of the vehicle, or loaded weight of the vehicle.
7. The method of claim 1, wherein the driver details may be extracted based on at least one of the at least one facial aspect of the driver, at least one biometric data associated with the driver, or a driver database comprising details associated with a plurality of drivers.
8. The method of claim 1, wherein the driver response may be determined based on at least one of biometric data associated with driver or changing vehicle attribute comprising at least one of vehicle deceleration, vehicle acceleration, or sudden vehicle orientation change.
9. The method of claim 1, wherein issuing a notification to the driver comprises determining a warning zone and a critical zone for the vehicle, the notification being issued when the vehicle is in the warning zone.
10. The method of claim 1, wherein the notification comprises at least one of a warning message, a warning sound, or a course correction audio message.
11. A mobile device for warning a driver of a vehicle, the mobile device comprising:
a processor;
at least one first camera coupled to the processor and being configured to capture at least one facial aspect of the driver;
at least one second camera coupled to the processor and being configured to capture a path view visible ahead of the vehicle up to a predefined distance; and
a memory communicatively coupled to the processor, the at least one first camera, and the at least one second camera, wherein the memory stores processor instructions, which, on execution, causes the processor to:
identify using image analytics a field of view of the driver, based on the at least one facial aspect and at least one path event demanding attention of the driver, based on the path view and the field of view of the driver;
detect absence of a driver response in response to identifying the at least one path event within the field of view of the driver;
extract driver details associated with the driver; and
issue a notification to the driver based on the driver details, when the absence of the driver response is detected.
12. The mobile device of claim 11, wherein the at least one facial aspect comprises at least one of gaze direction, facial direction, or eye position.
13. The mobile device of claim 11, wherein the processor instructions further cause the processor to retrieve environment details associated with environment around the vehicle and vehicle details associated with the vehicle.
14. The mobile device of claim 13, wherein the environment details are retrieved from a database or by using the at least one second camera, the environment details comprise at least one of road condition, weather condition, or traffic condition.
15. The mobile device of claim 13, wherein the vehicle details are retrieved from a vehicle management system onboard the vehicle, the vehicle details comprise at least one of brake conditions, tire condition, tire pressure, speed of the vehicle, or loaded weight of the vehicle.
16. The mobile device of claim 11, wherein the driver details are extracted based on at least one of the at least one facial aspect of the driver, at least one biometric data associated with the driver, or a driver database comprising details associated with a plurality of drivers.
17. The mobile device of claim 11, wherein the driver response is determined based on at least one of biometric data associated with driver or changing vehicle attribute comprising at least one of vehicle deceleration, vehicle acceleration, or sudden vehicle orientation change.
18. The mobile device of claim 11, wherein to issue a notification to the driver the processor instructions further cause the processor to determine a warning zone and a critical zone for the vehicle, the notification being issued when the vehicle is in the warning zone.
19. The mobile device of claim 11, wherein the notification comprises at least one of a warning message, a warning sound, or a course correction audio message.
