Abstract

Methods, apparatus, systems and articles of manufacture are disclosed for multimodal audience detection and identification. An example system disclosed herein includes at least one memory, instructions in the apparatus, and processor circuitry to execute the instructions to: select a portion of a set of signal strength values associated with advertising packets from a device associated with a user, the advertising packets captured by a multi-axis receiver on a plurality of different signal polarizations; calculate a first representative signal strength value based on the selected portion of signal strength values; and determine a presence of the user based on whether the first representative signal strength value satisfies a threshold.

First claim

What is claimed is:

1. A proximity detection system comprising a processor and a memory, the proximity detection system configured to:
select a portion of a set of signal strength values associated with advertising packets from a device, the device associated with a user, the advertising packets captured by a multi-axis receiver on a plurality of different signal polarizations;
calculate a first representative signal strength value based on the selected portion of signal strength values; and
determine a presence of the user based on whether the first representative signal strength value satisfies a threshold.

2. The proximity detection system of claim 1 , wherein the set of signal strength values includes signal strength values from one or more advertising channels and the plurality of different signal polarizations.

3. The proximity detection system of claim 1 , wherein the proximity detection system is configured to:
determine demographics associated with the user based on the advertising packets; and
generate a report indicating whether the presence of the user was detected.

4. The proximity detection system of claim 3 , wherein the presence is a first presence, and the proximity detection system is configured to:
detect a second presence of the user based on a radar reading;
correlate the first presence and the second presence to associate the demographics of the user with the second presence; and
track the user via the second presence.

5. The proximity detection system of claim 3 , wherein the proximity detection system is configured to transmit the report to a media meter, the media meter to conduct media monitoring based on the report.

6. The proximity detection system of claim 1 , wherein the proximity detection system is configured to:
access a second representative signal strength value from an auxiliary device; and
determine the presence based on the second representative signal strength value and on whether the first representative signal strength value satisfies the threshold.

7. The proximity detection system of claim 1 , wherein the advertising packets are Bluetooth advertising packets, and the signal strength values are received signal strength indicator (RSSI) values.

8. A non-transitory computer readable storage medium having stored thereon computer readable instructions that, when executed by a processor, cause performance of operations comprising:
selecting a portion of a set of signal strength values associated with advertising packets from a device associated with a user, the advertising packets captured by a multi-axis receiver on a plurality of different signal polarizations;
calculating a first representative signal strength value based on the selected portion of signal strength values; and
determining a presence of the user based on whether the first representative signal strength value satisfies a threshold.

9. The non-transitory computer readable storage medium of claim 8 , wherein the set of signal strength values includes signal strength values from one or more advertising channels and the plurality of different signal polarizations.

10. The non-transitory computer readable storage medium of claim 8 , wherein the operations further include determining demographics associated with the user based on the advertising packets, and generating a presence report indicating whether the presence of the user was detected.

11. The non-transitory computer readable storage medium of claim 10 , wherein the presence is a first presence, and wherein the operations further include:
detecting a second presence of the user based on a radar reading;
correlating the first presence and the second presence, the correlation associating the demographics of the user with the second presence; and
tracking the user via the second presence.

12. The non-transitory computer readable storage medium of claim 10 , wherein the operations further include transmitting the report to a media meter, the media meter to conduct media monitoring based on the report.

13. The non-transitory computer readable storage medium of claim 8 , wherein the operations further include:
receiving a second representative signal strength value from an auxiliary device; and
determining the presence based on the second representative signal strength value.

14. The non-transitory computer readable storage medium of claim 8 , wherein the advertising packets are Bluetooth advertising packets and the signal strength values are received signal strength indicator (RSSI) values.

15. A method comprising:
selecting a portion of a set of signal strength values associated with advertising packets from a device, the device associated with a user, the advertising packets captured by a multi-axis receiver on a plurality of different signal polarizations;
calculating a first representative signal strength value based on the selected portion of signal strength values; and
determining a presence of the user based on whether the first representative signal strength value satisfies a threshold.

16. The method of claim 15 , wherein the set of signal strength values includes signal strength values from one or more advertising channels and the plurality of different signal polarizations.

17. The method of claim 15 , further including:
determining demographics associated with the user based on the advertising packets; and
generating a presence report indicating whether the presence of the user was detected.

18. The method of claim 17 , wherein the presence is a first presence, the method further including:
detecting a second presence of the user based on a radar reading;
correlating the first presence and the second presence, the correlation associating the demographics of the user with the second presence; and
tracking the user via the second presence.

19. The method of claim 17 , further including transmitting the report to a media meter, the media meter to conduct media monitoring based on the report.

20. The method of claim 15 , further including:
receiving a second representative signal strength value from an auxiliary device; and
determining the presence based on the second representative signal strength value.
