Apple's new patent announcement: identify user status through pupil response to changes in brightness

CTOnews.com, April 11 (Xinhua)-- Apple's patent for "using brightness changes to determine user characteristics" has been announced.

The summary shows that the present disclosure relates to the determination of user characteristics using brightness changes. Some embodiments disclosed herein identify the user's state (e.g., concentration, distraction, distraction, etc.) based on the user's physiological response to a brightness change event in which some or all of the content quickly becomes brighter or darker (e.g., pupil).

The CTOnews.com attaches a relevant schematic diagram, which includes the steps of displaying the content on the display of the device, identifying the luminance change event associated with the content, obtaining the pupil response of the user who senses the luminance change event using the sensor, and evaluating the status of the user based on the pupil response.

The pupil is a small round hole in the center of the iris in the eye, which is the channel through which light enters the eye. The contraction of the pupil sphincter on the iris can narrow the pupil, the contraction of the pupil dilator makes the pupil dilate, and the dilation and contraction of the pupil control the amount of light entering the pupil.
