Methods and apparatus for multi-television measurements
Conventional television audience measurements are made with diaries or by imaging the area in front of a television and trying to identify the people in the images watching television. Unfortunately, diaries are only accurate if the audience members record entries in them, and image-based techniques are intrusive. The present techniques address these problems by using a viewer's wearable device to measure a viewer's proximity to a television. The wearable device emits or receives low-power beacon signals; measurements of the signal strength are used to calculate the viewer's distance to the television. If the viewer is close enough to the television and the television is on, the viewer may be engaged with the content on the television. This system is simple, non-intrusive, and can used to measure engagement with each television in a multi-television household.
1. A method of estimating engagement of a viewer with a particular program playing on a display device, the method comprising:
receiving, by a viewer device comprising one or more of a wearable device worn by the viewer and a mobile phone associated with the viewer, a first wireless beacon signal broadcast by a computing device while the program is playing on the display device, wherein the computing device is embodied in a compute stick and communicates with the display device via a means selected from a group comprising, a WiFi connection and a USB port;
receiving, by the viewer device, a second wireless beacon signal broadcast by a beacon while the program is playing on the display device;
acquiring, by the computing device, samples of an audio signal associated with the program playing on the display;
determining an identity of the program based on the samples of the audio signal;
estimating, based on the first beacon signal and the second beacon signal, a location of the viewer with respect to the display while the display is playing the program;
measuring, with the wearable device, at least one of a heartbeat of the viewer or movement of the wearable device;
assessing engagement of the viewer with the program playing on the display based on the location of the viewer with respect to the display and the at least one of the heartbeat of the viewer or the movement of the viewer device wherein the display device is one of multiple display devices within a residence, the viewer is one of multiple viewers within in the residence, the second wireless beacon signal is one of multiple second wireless beacon signals, and wherein each viewer is identifiable by the computing device;
providing by a server a status page of the server that can be accessed by an internet-connected device, wherein the status page shows a log that records the presence or absence of multiple viewers and times when the multiple users arrived or left, and wherein the log can be cleared by restarting the server from the status page, wherein the log is maintained by the system and is not maintained or regulated by a social media platform or any other online entity that is accessible to anyone not participating in the system;
receiving, by the viewer device, a third beacon signal from another computing device associated with another display device while another program is playing on the other display device;
estimating a location of the viewer with respect to the other display device based on the third beacon signal; and
assessing engagement of the viewer with the other program playing on the other display device based on the location of the viewer with respect to the other display device.
2. The method of claim 1 , further comprising:
transmitting measurements of the first beacon signal and the second beacon signal from the viewer device to the server, wherein the server is remote from the residence, and wherein the computing device communicates with the server via a network interface.
3. The method of claim 2 , wherein determining an identity of the program based on the samples of the audio signal comprises generating audio fingerprints and comparing the fingerprints to information in a database.
4. The method of claim 3 , further comprising:
storing the audio fingerprints, the identity of the program, the location of the viewer, and an identity of the viewer in a memory of the computing device; and transmitting the audio fingerprints, the identity of the program, the location of the viewer, and the identity of the viewer to the server under predetermined circumstances.
5. The method of claim 4 , further comprising generating and storing a timestamp that indicates when the location of the viewer and the audio samples were collected.
