Inaudible frequency transmission in interactive content

A method comprising:

• detecting an inaudible signal associated with an audible signal, the inaudible signal including a signature associated with an electronic device;
• activating a monitor to detect a user gesture, wherein the monitor is activated for a predetermined time responsive to the signature;
• determining a characteristic of the audible signal based on the inaudible signal;
• and
• transmitting a message based on the characteristic on a condition that the user gesture corresponds to the message and is received within the predetermined time.

An electronic device comprising:

• a receiver configured to detect an inaudible signal associated with a first audible signal of an audio input, the inaudible signal including one or more frequency signatures;
• a processor configured to:
• activate a response monitor for a predetermined time to detect a user gesture response based on the one or more frequency signatures;
• and
• generate a message based on a content characteristic of the first audible signal;
• and
• a transmitter configured to transmit the message to an environment control device on a condition that the user gesture response corresponds to the message and is received within the predetermined time.

A method comprising:

• detecting a first signal associated with a second signal of an audio input, the first signal including one or more frequency signatures corresponding to one or more devices;
• determining a characteristic of the second signal based on the first signal;
• responsive to the detection of at least one of the one or more frequency signatures in the first signal, activating a monitor to detect a gesture within a predefined time;
• and
• responsive to the gesture being detected within the predefined time, transmitting a message generated based on the characteristic.
