Methods and apparatus for detecting a composition of an audience of an information presenting device
Methods and apparatus for detecting a composition of an audience of an information presenting device are disclosed. A disclosed example method includes maintaining a first count of a number of people detected in an environment based on image data representative of the environment; when the image data is indicative of a change in the number of people detected in the environment, presenting a request for identity information; determining if the people were compliant in providing the identity information based on a difference between the number of people appearing in the image data and a second number of received identity responses; and when the people were non-compliant in providing the identity information, increasing a second count maintained for the environment indicative of unidentified people in the room.
1. A method, comprising:
maintaining a first count of a number of people detected in an environment based on image data representative of the environment;
when the image data is indicative of a change in the number of people detected in the environment, presenting a request for identity information;
determining, with a processor if the people were compliant in providing the identity information based on a difference between the number of people appearing in the image data and a second number of received identity responses; and
when the people were non-compliant in providing the identity information, increasing, with the processor, a second count maintained for the environment indicative of unidentified people in the environment.
2. A method as defined in claim 1 , further comprising storing the second count in a memory in association with a time stamp.
3. A method as defined in claim 1 , wherein determining if the people were compliant in providing the identity information comprises determining whether the difference between the number of people appearing in the image data and the second number of received identity responses occurs a plurality of successive times.
4. A method as defined in claim 1 , further comprising increasing the first count by a value of the second count to generate an increased first count, wherein the increased first count is to be used for analyzing subsequent instances of image data.
5. A method as defined in claim 1 , wherein presenting the request for identity information comprises generating a visual display in the environment.
6. A method as defined in claim 1 , wherein presenting the request for identity information comprises presenting a list of identifiers corresponding to persons of a household.
7. A method as defined in claim 1 , further comprising associating media identifying information with at least one of the first count or the second count.
8. A tangible machine readable storage device or storage disc comprising instructions that, when executed, cause a machine to at least:
maintain a first count of a number of people detected in an environment based on image data representative of the environment;
when the image data is indicative of a change in the number of people detected in the environment, present a request for identity information;
determine if the people were compliant in providing the identity information based on a difference between the number of people appearing in the image data and a second number of received identity responses; and
when the people were non-compliant in providing the identity information, increase a second count maintained for the environment indicative of unidentified people in the environment.
9. A storage device or storage disc as defined in claim 8 , wherein the instructions cause the machine to store the second count in a memory in association with a time stamp.
10. A storage device or storage disc as defined in claim 8 , wherein the instructions cause the machine to determine if the people were compliant in providing the identity information by determining whether the difference between the number of people appearing in the image data and the second number of received identity responses is detected a plurality of successive times.
11. A storage device or storage disc as defined in claim 8 , wherein the instructions cause the machine to increase the first count by a value of the second count to generate an increased first count, wherein the increased first count is to be used for analyzing subsequent instances of image data.
12. A storage device or storage disc as defined in claim 8 , wherein the instructions cause the machine to present the request for identity information by generating a visual display in the environment.
13. A storage device or storage disc as defined in claim 8 , wherein instructions cause the machine to present the request for identity information by presenting a list of identifiers corresponding to persons of a household.
14. A storage device or storage disc as defined in claim 8 , wherein the instructions cause the machine to associate media identifying information with at least one of the first count or the second count.
15. An apparatus, comprising:
a people counter to maintain a first count of a number of people detected in an environment based on image data representative of the environment;
a change detector to, when the image data is indicative of a change in the number of people detected in the environment, present a request for identity information; and
a compliance detector to:
determine if the people were compliant in providing the identity information based on a difference between the number of people appearing in the image data and a second number of received identity responses; and
when the people were non-compliant in providing the identity information, increase a second count maintained for the environment indicative of unidentified people in the environment, wherein at least one of the people counter, the change detector or the compliance detector is implemented via a logic circuit.
16. An apparatus as defined in claim 15 , further comprising memory to store the second count in association with a time stamp.
17. An apparatus as defined in claim 15 , wherein the compliance detector is to determine if the people were compliant in providing the identity information by determining whether the difference between the number of people appearing in the image data and the second number of received identity responses is detected a plurality of successive times.
18. An apparatus as defined in claim 15 , wherein the people counter is to increase the first count by a value of the second count to generate an increased first count, wherein the increased first count is to be used for analyzing subsequent instances of image data.
19. An apparatus as defined in claim 15 , wherein the compliance detector is to present the request for identity information by presenting a list of identifiers corresponding to persons of a household.
20. An apparatus as defined in claim 15 , further comprising a media detector to associate media identifying information with at least one of the first count or the second count.
