Methods and apparatus to determine engagement levels of audience members
Methods and apparatus to determine engagement levels of audience members are disclosed. An example method includes capturing, with a sensor, image data depicting an environment in which a first media device is to present media. Analyzing the image data to determine whether the environment includes a second media device emanating a glow. When the environment includes the second media device emanating the glow, calculating an engagement for a person in the environment with respect to the first media device, the engagement being calculated based on a characteristic of the second media device emanating the glow.
1. A method, comprising:
capturing, with a sensor, image data depicting an environment in which a first media device is to present media;
analyzing, by executing an instruction with a processor, the image data to determine whether the environment includes a second media device emanating a glow; and
when the environment includes the second media device emanating the glow, calculating, by executing an instruction with the processor, an engagement for a person in the environment with respect to the first media device, the engagement being calculated based on a distance between the person and the second media device emanating the glow.
2. The method as defined in claim 1 , further including detecting a change in the glow over a period of time.
3. The method as defined in claim 2 , wherein the engagement is further calculated based on the detected change in the glow.
4. The method as defined in claim 1 , wherein the sensor is separate from the first media device and the second media device.
5. The method as defined in claim 1 , further including:
detecting media identifying information associated with the first media device; and
associating the media identifying information with the calculated engagement.
6. The method as defined in claim 1 , wherein the first media device is a stationary device located in the environment, and the second media device is a portable device.
7. A tangible computer readable storage medium comprising instructions that, when executed, cause a machine to at least:
access image data captured by a sensor, the image data depicting an environment in which a first media device is to present media;
analyze the image data to determine whether the environment includes a second media device emanating a glow; and
when the environment includes the second media device emanating the glow, calculate an amount of attention paid by a person in the environment to the first media device, the amount of attention to be calculated based on a distance between the person and the second media device emanating the glow.
8. The storage medium as defined in claim 7 , wherein the instructions, when executed, cause the machine to detect a change in the glow over a period of time.
9. The storage medium as defined in claim 8 , wherein the instructions, when executed, cause the machine to further calculate the amount of attention paid by the person based on the detected change in the glow.
10. The storage medium as defined in claim 7 , wherein the sensor is separate from the first media device and the second media device.
11. The storage medium as defined in claim 7 , wherein the instructions, when executed, further cause the machine to:
gather media identifying information associated with the first media device; and
associate the media identifying information with the calculated engagement.
12. The storage medium as defined in claim 7 , wherein the first media device is a stationary device located in the environment, and the second media device is a portable device.
13. An apparatus, comprising:
a detector to analyze image data depicting an environment in which media is to be presented by a first media device to determine whether the environment includes a second media device emanating a glow, the image data captured with a sensor; and
a calculator to determine an engagement for a person in the environment with respect to the first media device, the calculator to determine the engagement based on a distance between the person and the second media device emanating the glow.
14. The apparatus as defined in claim 13 , wherein the detector is to detect a change in the glow over a period of time.
15. The apparatus as defined in claim 14 , wherein the calculator is to further determine the engagement for the person based on the detected change in the glow.
16. The apparatus as defined in claim 13 , wherein the sensor is separate from the first media device and the second media device.
17. The apparatus as defined in claim 13 , further including a media detector to collect media identifying information to associate with the calculated engagement.
18. The apparatus as defined in claim 13 , wherein the first media device is a stationary device located in the environment, and the second media device is a portable device.
