Abstract

A system to identify a user in relation with television services comprising eyeglasses worn by said user, said eyeglasses having a pair of flexible temples taking on the shape of a portion of the circumference of the user'"'"'s head, a television receiver device comprising a server module communicating wirelessly with sensors arranged on the eyeglasses. The system is characterized in that each of the flexible temples of the eyeglasses incorporates at least one sensor configured for measuring a value of deflection caused by the temple bending around a portion of the circumference of the user'"'"'s head, said value being unique for each user is transmitted as biometric to the server module configured for determining the identity of the user according to the measured value of the portion of the user'"'"'s head circumference.

Claims

1. A system to identify a user in relation with television services comprising eyeglasses worn by said user, said eyeglasses having a pair of flexible temples taking on the shape of a portion of the circumference of the user'"'"'s head, a television receiver device comprising a server module communicating wirelessly with sensors arranged on the eyeglasses, wherein each of the flexible temples of the eyeglasses incorporates at least one sensor configured for measuring a value of deflection caused by the temple bending around a portion of the circumference of the user'"'"'s head, said value being unique for each user and is transmitted as biometric to the server module configured for determining the identity of the user according to the measured value of the portion of the user'"'"'s head circumference.

2. The system according to claim 1 wherein the sensor is made up of a bend sensor and of a transmitter incorporated in each temple of the eyeglasses, said bend sensor producing measurement values corresponding to the temple deflection, said values being transmitted wirelessly by the transmitter to the server module.

3. The system according to claim 2 wherein the bend sensor is a conductive ink-based sensor which electrical resistance changes depending on the amount of deflection on the bend sensor.

4. The system according to claim 2 wherein the bend sensor is a fiber-optic based sensor which light conductivity varies with the amount of deflection on the bend sensor.

5. The system according to claim 2 wherein the bend sensor is conductive fabric, thread, or polymer-based sensor which electrical conductivity varies with the amount of deflection on the bend sensor.

6. The system according to claim 1 wherein the sensor is made up of an optical sensor comprising light reflective markers attached to the flexible temples of the eyeglasses and aligned along the length of the temple and of at least one camera arranged near the location of the user'"'"'s head acquiring the biometrics by measuring the value of deflection of the temples through position variations of the markers determined by the user'"'"'s head circumference, said value being transmitted wirelessly to the server module by a transmitter included in the camera.

7. The system according to claim 6 wherein the position variations of the markers on the temples are determined between a neutral position and a bend position determined by the user'"'"'s head circumference, the neutral position being defined by the position of the markers when the eyeglasses are put off from the user'"'"'s head.

8. The system according to claim 6 wherein the optical sensor further comprises light reflective markers attached to screens of media viewing platforms watched by the user wearing the eyeglasses having optical markers on the temples, the server module further comprising means for estimating a position of the screens and user'"'"'s head pose and means for identifying the screen currently watched for audience measurement purposes.

9. The system according to claim 1 wherein the server module comprises a receiver connected to a feature extraction module which is connected to a matcher module using an enrollment database, the matcher module having means for comparing a set of features extracted from the received measurement values produced by the sensor by the feature extraction module with reference templates recorded in the enrolment database to establish the identity of the user.
