Abstract
A presence detector for detecting and estimating an audience watching television comprising: one or more presence sensors adapted to capturing signals emitted by or reflected from the audience; and a translator connected to the one or more presence sensors adapted to translating output signals created by the one or more presence sensors to data signals representing the estimated number of people in the audience. Presence information captured is converted to television rating data and is very useful for pricing advertisements accurately.
Claims20
A presence detector for detecting an audience, comprising:
- a plurality of pyroelectric detectors for capturing thermal signals emitted by the audience;
- a plurality of lenses, wherein each lens is positioned in front of a pyroelectric detector;
- and
- one or more microprocessors connected to said plurality of pyroelectric sensors for translating thermal signals created by the plurality of pyroelectric detectors to data signals representing the estimated number of people in the audience.
A presence detector for detecting and estimating an audience watching television, comprising:
- one or more presence sensors adapted to capturing sound signals, infrared signals, electromagnetic signals or optical signals emitted by or reflected from the audience, wherein said one or more presence sensors comprise:
- a pyroelectric detector, an ultrasonic transceiver, a thermopile sensor, an imaging camera, an imaging camera with a VMD algorithm, an imaging camera with a face detection algorithm, a photodiode, IR receiver, or an electro-optic detector coupled to a light source;
- and
- a translator connected to said one or more presence sensors adapted to translating output signals created by the one or more presence sensors to data signals representing the estimated number of people in the audience.
