METHODS AND SYSTEMS FOR DRIVER IDENTIFICATION
First Claim
1. A method of determining vehicle entry information for a user, the method comprising:
- obtaining a yaw measurement using a mobile device;
determining, using a processor, a first time span associated with a user entering a vehicle;
determining, using the processor, a second time span associated with a user exiting the vehicle;
determining that a change in magnitude over a portion of the yaw measurement is greater than a predetermined threshold over at least one of the first time span or the second time span;
determining an angular change of the yaw measurement over the predetermined threshold;
associating right hand entry with the vehicle entry information if the angular orientation of the yaw measurement is clockwise; and
associating left hand entry with the vehicle entry information if the angular orientation of the yaw measurement is counter-clockwise.

Abstract
A method of determining vehicle entry information for a user includes obtaining a yaw measurement using a mobile device, determining, using a processor, a first time span associated with a user entering a vehicle, and determining, using the processor, a second time span associated with a user exiting the vehicle. The method also includes determining that a change in magnitude over a portion of the yaw measurement is greater than a predetermined threshold over at least one of the first time span or the second time span and determining an angular change of the yaw measurement over the predetermined threshold. The method further includes associating right hand entry with the vehicle entry information if the angular orientation of the yaw measurement is clockwise and associating left hand entry with the vehicle entry information if the angular orientation of the yaw measurement is counter-clockwise.
