Reducing power consumption of sensor by overriding instructions to measure

A method for reducing power consumption by overriding an instruction to measure affective response to content, comprising:

• receiving first and second tags corresponding to first and second segments of content, respectively;
• wherein the first and second tags indicate to operate a device in a first mode of operation to measure affective response to the first and second segments;
• receiving a first measurement of a user taken by a sensor before end of exposure of the user to the first segment;
• determining that the first measurement reaches a first predetermined threshold, and selecting the first mode of operation for the device to operate in to measure affective response of the user to the first segment;
• receiving a second measurement of the user taken by the sensor before end of exposure of the user to the second segment;
• and
• determining that the second measurement does not reach a second predetermined threshold, and overriding first mode of operation indicated by the second tag by selecting a second mode of operation in which to operate the device to measure affective response of the user to the second segment;
• wherein power consumption of the device when operating in the second mode of operation is at least 50% lower than the power consumption of the device when operating in the first mode of operation.

A non-transitory computer-readable medium for use in a computer to for reduce power consumption by overriding an instruction to measure affective response to content;

• the computer comprises a processor, and the non-transitory computer-readable medium comprising:
• program code for receiving first and second tags corresponding to first and second segments of content, respectively;
• wherein the first and second tags indicate to operate a device in a first mode of operation to measure affective response to the first and second segments;
• program code for receiving a first measurement of a user taken by a sensor before end of exposure of the user to the first segment;
• program code for determining that the first measurement reaches a first predetermined threshold and selecting the first mode of operation for the device to operate in to measure affective response of the user to the first segment;
• program code for receiving a second measurement of the user taken by the sensor before end of exposure of the user to the second segment;
• and
• program code for determining that the second measurement does not reach a second predetermined threshold and overriding first mode of operation indicated by the second tag by selecting a second mode of operation in which to operate the device to measure affective response of the user to the second segment;
• wherein power consumption of the device when operating in the second mode of operation is at least 50% lower than the power consumption of the device when operating in the first mode of operation.
