Abstract

A computing system such as a game console maintains and updates a biometric profile of a user. In one aspect, biometric data of the user is continuously obtained from a sensor such as an infrared and visible light camera, and used to update the biometric profile using a machine learning process. In another aspect, a user is prompted to confirm his or her identify when multiple users are detected at the same time and/or when the user is detected with a confidence level which is below a threshold. A real-time image of the user being identified can be displayed on a user interface with user images associated with one or more accounts. In another aspect, the biometric profile is managed by a shell on the computing system, where the shell makes the biometric profile available to any of a number of applications on the computing system.

Claims

1. A computer-implemented method for recognizing a user, comprising:

obtaining biometric data of a first user from a sensor while the first user is in a field of view of the sensor;

determining a biometric profile which is a best match to the biometric data of the first user, the biometric profile is linked to a first user account;

determining a confidence level of the best match;

if the confidence level is above a threshold, signing the first user into the first user account without prompting the first user to confirm his or her identity; and

if the confidence level is below the threshold, informing the first user that he or she is believed to be associated with the first user account and prompting the first user to confirm his or her identity.

2. The computer-implemented method of claim 1, wherein:

the informing the first user that he or she is believed to be associated with the first user account comprises displaying an image of a user associated with the first user account and displaying a real-time image of the first user from the sensor.

3. The computer-implemented method of claim 1, where the method performed further comprises:

in response to the first user confirming his or her identity, signing the first user into the first user account.

4. The computer-implemented method of claim 1, where the method performed further comprises:

determining a biometric profile which is a second best match to the biometric data of the first user, the biometric profile which is the second best match is linked to a second user account; and

informing the first user that he or she is believed to be associated with the second user account as a second best match after the first user account.

5. The computer-implemented method of claim 4, wherein:

the informing the first user that he or she is believed to be associated with the first user account comprises displaying an image of a user associated with the first user account and displaying a real-time image of the first user from the sensor; and

the informing the first user that he or she is believed to be associated with the second user account as a second best match after the first user account comprises displaying an image of a user associated with the second user account and displaying the real-time image of the first user from the sensor.

6. A computer-readable storage device having computer-readable software embodied thereon for programming a processor to perform a method for recognizing a user, the method comprising:

signing a first user into an account in a computing system, the account associates the first user with a biometric profile of the first user, the biometric profile comprises biometric data of the first user obtained from a sensor;

obtaining additional biometric data of the first user from the sensor while the first user is signed into the account and while the first user is in a field of view of the sensor; and

updating the biometric profile based on the additional biometric data.

7. The computer-readable storage device of claim 6, wherein:

the biometric data of the biometric profile is classified into different categories based on biometric data-gathering conditions; and

a rate of the obtaining the additional biometric data is based on a current biometric data-gathering condition and an amount of biometric data which has been gathered with the current biometric data-gathering condition, the rate is relatively higher when the amount of biometric data which has been gathered with the current biometric data-gathering condition is relatively lower.

8. The computer-readable storage device of claim 7, wherein:

the different categories include categories for different lighting conditions.

9. The computer-readable storage device of claim 7, wherein:

the different categories include categories for distance of the first user from the sensor.

10. The computer-readable storage device of claim 6, wherein:

the biometric profile is managed by a shell on the computing system; and

the shell makes the biometric profile available to any of a plurality of applications on the computing system so that the plurality of applications can identify the first user using the biometric profile.

11. The computer-readable storage device of claim 6, wherein:

the sensor comprises an active infrared sensor; and

the additional biometric data comprises facial recognition data.
