Classification: CPC A  G | IPC G

Claim 0:
1. A method of assessing state of a user, the method comprising:
at a device comprising a processor, a display, and a sensor:
identifying a luminance change event associated with content on the display;
obtaining, using the sensor, a pupillary response of a user perceiving the luminance change event associated with the content on the display;
determining a magnitude of the pupillary response of the user to the luminance change event;
assessing a state of the user based on the magnitude of pupillary response of the user perceiving the luminance change, wherein a first state is determined where the magnitude of the pupillary response is relatively larger than a magnitude associated with a prior pupillary response while a second state is determined where the magnitude of the pupillary response is relatively smaller than the magnitude associated with the prior pupillary response; and
providing a response based on the state of the user, wherein the response comprises:
a suggestion for the user to rewatch a particular portion of the content;
a suggestion for the user to change a presentation speed of the content;
a suggestion identifying a similar moment in other content; or
a suggestion for the user to view the content or other content at a particular time or under particular conditions.
