User identification systems and methods
Example user identification systems and methods are described. In one implementation, a method determines a first step pulse associated with a user carrying a key fob and detects a user device proximate the key fob. The method further identifies a second step pulse measured by the user device and determines whether the first and second step pulses match. If the step pulses match, the user carrying the key fob is identified as the owner of the user device.
1. A method comprising:
determining a first step pulse associated with a user carrying a key fob;
detecting a user device proximate the key fob;
determining, at the user device, a second step pulse;
broadcasting, at the user device, information related to the second step pulse into an area proximate the user device;
determining, using one or more processors, whether the first and second step pulses match; and
responsive to determining matching step pulses, identifying the user carrying the key fob as the owner of the user device.
2. The method of claim 1 , further comprising accessing a user profile associated with the identified user, wherein the user profile is associated with a vehicle.
3. The method of claim 2 , further comprising unlocking at least one vehicle access point based on the user profile.
4. The method of claim 3 , wherein the vehicle access point is one of a vehicle door, a trunk, a tailgate, a sliding door, a hatch, a hood and a gas tank refill door.
5. The method of claim 2 , further comprising setting at least one vehicle configuration based on the user profile.
6. The method of claim 5 , wherein the vehicle configuration is one of a radio station setting, a preferred climate control setting, a seat position setting, a mirror setting, vehicle navigation settings, personalization settings and a welcome display projected in or around the vehicle.
7. The method of claim 1 , wherein the user device for measuring the second step pulse is one of a smartphone, a portable computing device and a smart watch.
8. The method of claim 1 , wherein the first step pulse identifies temporal spacing between consecutive heel strikes of the user carrying the key fob.
9. The method of claim 1 , wherein the broadcast information relating to the second step pulse is received at the key fob or a vehicle associated with the key fob.
10. The method of claim 1 , wherein the key fob determines whether the first and second step pulses match.
11. The method of claim 1 , wherein a vehicle controller in a vehicle associated with the key fob determines whether the first and second step pulses match.
12. A method comprising:
determining a first step pulse associated with a user carrying a key fob;
determining, at a user device associated with the user, a second step pulse;
receiving a broadcast into an area proximate the user device from the user device proximate the key fob, the received broadcast including a second step pulse measured by the user device and an identification of the user carrying the user device;
comparing, using one or more processors, the first step pulse and the second step pulse to determine whether the first step pulse and the second step pulse match; and
responsive to determining that the first step pulse and the second step pulse match, identifying the user carrying the key fob based on the received identification of the user carrying the user device.
13. The method of claim 12 , further comprising accessing a user profile associated with the identified user, wherein the use profile is associated with a vehicle.
14. The method of claim 13 , further comprising setting at least one vehicle configuration based on the user profile.
15. The method of claim 14 , wherein the vehicle configuration is one of a radio station setting, a preferred climate control setting, a seat position setting, a mirror setting, vehicle navigation settings, personalization settings and a welcome display projected in or around the vehicle.
16. The method of claim 12 , wherein the first step pulse identifies temporal spacing between consecutive heel strikes of the user carrying the key fob.
17. The method of claim 12 , wherein a vehicle controller in a vehicle associated with the key fob receives information associated with the first and second step pulses.
18. An apparatus carried by a user, the apparatus comprising:
an accelerometer configured to identify a first step pulse associated with the user;
a communication module configured to receive a broadcast into an area proximate the user device from a user device proximate the apparatus, the received broadcast including information associated with a second step pulse determined at the user device and an identification of a second user carrying the user device; and
a processor coupled to the accelerometer and the communication module, the processor configured to compare the first step pulse and the second step pulse to determine whether the first step pulse and the second step pulse match, the processor further configured to identify the user based on the identification of the second user responsive to determining that the first step pulse and the second step pulse match.
19. The apparatus of claim 18 , wherein the communication module is further configured to communicate the identity of the user to a vehicle associated with the apparatus.
