Abstract
A method for detecting an eye event of a user using an eye tracking system, the method comprising capturing a first image of a first eye of a user, capturing an image of a second eye of the user a first period after capturing the first image of the first eye and a second period before capturing a next image of the first eye, capturing a second image of the first eye the second period after capturing the image of the second eye, determining that an eye event has occurred based on a difference between the first and second images of the first eye, and performing at least one action if it is determined that that an eye event has occurred.
Claims19
A method for detecting an eye event of a user using an eye tracking system, the method comprising:
- capturing a first image of a first eye of a user;
- capturing an image of a second eye of the user a first period after capturing the first image of the first eye and a second period before capturing a next image of the first eye;
- capturing a second image of the first eye the second period after capturing the image of the second eye;
- determining that an eye event has occurred based on a difference between the first and second images of the first eye;
- and
- performing at least one action if it is determined that that an eye event has occurred.
An eye tracking system comprising:
- at least one first image capture device configured to capture images of a first eye of a user;
- at least one second image capture device configured to capture images of a second eye of the user;
- and
- a processor;
- wherein the system is configured to:
- capture a first image of the first eye;
- capture a first image of the second eye a first period after capturing the first image of the first eye and a second period before capturing a next image of the first eye;
- capture a second image of the first eye the second period after capturing the first image of the second eye;
- determine that an eye event has occurred based on a difference between the first and second images of the first eye;
- and
- perform at least one action if it is determined that that an eye event has occurred.
A computer program comprising instructions which, when executed on at least one processor, cause the at least one processor to control an eye tracking system to:
- capture a first image of a first eye of a user;
- capture a first image of a second eye of the user a first period after capturing the first image of the first eye and a second period before capturing a next image of the first eye;
- capture a second image of the first eye the second period after capturing the first image of the second eye;
- determine that an eye event has occurred based on a difference between the first and second images of the first eye;
- and
- perform at least one action if it is determined that that an eye event has occurred.
