Abstract: Methods, apparatus, and systems are disclosed for estimating audience exposure based on engagement level. An example apparatus includes at least one memory, machine readable instructions, and processor circuitry to at least one of instantiate or execute the machine readable instructions to identify a user activity associated with a user during exposure of the user to media based on an output from at least one of a user device, a remote control device, an image sensor, or a motion sensor, classify the user activity as an attention-based activity or a distraction-based activity, assign a distraction factor or an attention factor to the user activity based on the classification, and determine an attention level for the user based on the distraction factor or the attention factor.

Abstract: Remote control devices to interface with audience measurement meters are disclosed. An example remote control device to interface with an audience measurement meter includes an audience management controller to, responsive to a gender value input via a user interface of the remote control device, store the gender value, responsive to an age value input via the user interface of the remote control device, store the age value, generate a message including the gender value and age value, and a transmitter to transmit the message to the audience measurement meter, the message including a sequence of infrared codes.

Abstract: Systems, apparatus, articles of manufacture, and methods are disclosed for media monitoring and audience measurement. An example system includes a symbol alphabet meter to generate a query symbol alphabet based on captured data of an optical pulse stream, the optical pulse stream detected from a media remote control. The example system also includes a symbol alphabet matcher to apply a probability function to the query symbol alphabet and a reference symbol alphabet to determine a symbol alphabet matching probability, and determine a symbol alphabet match based on the symbol alphabet matching probability. In addition, the example system includes a key code detector to determine a key code based on the symbol alphabet match.

Abstract: Methods and apparatus are disclosed for media monitoring and audience measurement. For example, an optical capture meter can capture data of an optical pulse stream detected from a media remote control. A key code detector can determine a key code, based on a query optical pulse signature including a query symbol alphabet. The key code corresponds to the key activated on the media remote control to control a media activity (e.g., changing television channels.) The foregoing can provide a generalized way of key code detection of media remote controls from various different manufacturers without complete prior knowledge and/or implementations of various different infrared signaling protocols employed in various media remote controls.
