Mental state analysis using blink rate for vehicles
First Claim
1. A computer-implemented method for mental state analysis comprising:
- obtaining video of an individual with an image capture device;
analyzing, using one or more processors, the video to detect a blink event based on a classifier for a blink that was determined wherein the blink event is determined by identifying that eyes of the individual are closed for a frame in the video using temporal analysis;
evaluating, using the one or more processors, a blink duration of the individual for the blink event;
determining, using the one or more processors, blink-rate information using the blink event and one or more other blink events;
compensating, using the one or more processors, the blink-rate information for a context;
evaluating blinking for a group of people of which the individual is a part;
determining a difference in blinking between the individual and a remainder of the group; and
inferring, using the one or more processors, mental states of the individual for the blink event, wherein the mental states are based on the blink event, the blink duration of the individual, the difference in blinking between the individual and the remainder of the group, and the blink-rate information that was compensated.

Abstract
Mental state analysis is performed by obtaining video of an individual as the individual interacts with a computer, either by performing various operations, such as driving a vehicle or being a passenger in a vehicle, or by consuming a media presentation. The video is analyzed to determine eye-blink information on the individual, such as eye-blink rate or eye-blink duration. The blink-rate information is compensated for a context. Blinking for a group of people of which the individual is a part is evaluated. Mental states of the individual are inferred for the blink event based on the blink event, the blink duration of the individual, the difference in blinking between the individual and the remainder of the group, and the blink-rate information that was compensated. The blink-rate information and associated mental states can be used to modify an advertisement, a media presentation, a digital game, or vehicle controls.

28. A computer program product embodied in a non-transitory computer readable medium for mental state analysis, the computer program product comprising code which causes one or more processors to perform operations of:
-
obtaining video of an individual with an image capture device; analyzing, using one or more processors, the video to detect a blink event based on a classifier for a blink that was determined wherein the blink event is determined by identifying that eyes of the individual are closed for a frame in the video using temporal analysis; evaluating, using the one or more processors, a blink duration of the individual for the blink event; determining, using the one or more processors, blink-rate information using the blink event and one or more other blink events; compensating, using the one or more processors, the blink-rate information for a context; evaluating blinking for a group of people of which the individual is a part; determining a difference in blinking between the individual and a remainder of the group; and inferring, using the one or more processors, mental states of the individual for the blink event, wherein the mental states are based on the blink event, the blink duration of the individual, the difference in blinking between the individual and the remainder of the group, and the blink-rate information that was compensated.

29. A computer system for mental state analysis comprising:
-
a memory which stores instructions; one or more processors attached to the memory wherein the one or more processors, when executing the instructions which are stored, are configured to; obtain video of an individual with an image capture device; analyze the video to detect a blink event based on a classifier for a blink that was determined wherein the blink event is determined by identifying that eyes of the individual are closed for a frame in the video using temporal analysis; evaluate a blink duration of the individual for the blink event; determine blink-rate information using the blink event and one or more other blink events; compensate the blink-rate information for a context; evaluate blinking for a group of people of which the individual is a part; determine a difference in blinking between the individual and a remainder of the group; and infer mental states of the individual for the blink event, wherein the mental states are based on the blink event, the blink duration of the individual, the difference in blinking between the individual and the remainder of the group, and the blink-rate information that was compensated.
