Utilizing eye tracking to reduce power consumption involved in measuring affective response

摘要

Systems and methods that enable a reduction of the power consumption involved in measuring a user's affective response to content. The reduction in power consumption is achieved by utilizing eye tracking to determine when a user is paying attention to content, and accordingly setting a mode of operation of a device that measures the user. Thus, by using different modes of operation, which are characterized by different energy consumption rates, the total power consumption of the device may be reduced, without loss of relevant measurements.

主权项

1. A controller configured to utilize eye tracking data to reduce power consumption of a device operative to measure affective response, comprising:
a first interface configured to receive a first tag that indicates a first duration during which to measure affective response to a first segment of content by operating the device in a first mode of operation; a second interface configured to receive first eye tracking data of a user acquired in temporal vicinity of the first duration; and a processor configured to: analyze the first eye tracking data, determine that a gaze-based attention level to the first segment reaches a first predetermined threshold, and to select the first mode of operation for operating the device, during the first duration, to measure affective response of the user to the first segment; the first interface is further configured to receive a second tag that indicates a second duration during which to measure affective response to a second segment of content by operating the device in a first mode of operation; the second interface is further configured to receive second eye tracking data of the user acquired in temporal vicinity of the second duration; the processor is further configured to: analyze the second eye tracking data, determine that a gaze-based attention level to the second segment does not reach a second predetermined threshold, and to select a second mode of operation for operating the device, during the second duration, to measure affective response of the user to the second segment; wherein power consumption of the device when operating in the first mode of operation is significantly higher than the power consumption of the device when operating in the second mode of operation.
