Method and use of smartphone camera to prevent distracted driving
First Claim
1. A method of restricting access to at least one application on a wireless communication device, comprising steps of:
- obtaining image data of a user of the wireless communication device with a camera sensor operatively coupled to the wireless communication device;
then, performing image analysis of image data, on a processor operatively coupled to the wireless communication device, to calculate at least one of the following metrics;
A. a duration of a user'"'"'s gaze in the direction of the wireless communication device'"'"'s camera sensor,B. a rate of the user'"'"'s gaze from a first direction, defined as towards the wireless communication device'"'"'s camera sensor, to a second direction, defined as towards anywhere but the wireless communication device'"'"'s camera sensor, with respect to time, andC. a duty cycle of the user'"'"'s gaze from a first direction, defined as towards the wireless communication device'"'"'s camera sensor, to a second direction, defined as towards anywhere but the wireless communication device'"'"'s camera sensor,then, generating a composite probability calculation as to whether the user of the wireless communication device is distracted, the composite probability calculation is defined as a weighted mathematical combination of probabilities, wherein the probabilities to be combined are the probabilities resulting from comparing the duration, rate, and duty cycle metrics that were calculated, each to a corresponding threshold,then, comparing the composite probability calculation to a probability threshold, resulting in one of two outcomes;
A. the user of the wireless communication device is not distracted, at which point the wireless communication device permits access to at least one application on the wireless communication device, andB. the user of the wireless communication device is distracted, at which point the wireless communication device performs at least one of;
restricting access to at least one application on the wireless communication device,alerting the user of the wireless communication device, andalerting third-parties using a communications protocol supported by the wireless communication device;
then, repeating the method based on a selectable time interval.

Abstract
A method and use are described for disabling certain wireless communication device functionalities based on input from the device'"'"'s user-facing camera. More particularly, image data of the user is collected, image analysis is used to extract certain metrics about the user, and if those metrics are in violation of one or more thresholds one or more device functionalities are disabled. The functionality may be disabled for a period of time or until the user'"'"'s image metrics fall below one or more thresholds. The disabled device functionalities may also be extended to connected peripheral devices. Finally, records of threshold violations resulting in disabled device functionality may be stored on the device or a database and made available to third parties.
