Abstract
Aspects of the present disclosure relate to eye tracking systems and methods which track eyes by illuminating the eyes using a light source and detecting the eye illuminations using a sensor. Implementations of the present disclosure may utilize a light source with a dynamic lighting position to account for changes in lighting conditions during the tracking which interfere with detection of the eye illuminations, such as reflections in glasses which may obscure a user's eyes.
Claims20
A method comprising:
- emitting light from an eye tracking device;
- capturing one or more images with the eye tracking device of an area illuminated by said emitting the light;
- determining one or more gaze characteristics from analysis of the images based on eye illuminations within the images from said emitting the light;
- analyzing the images to detect a pre-defined change in lighting conditions in the images;
- and
- triggering a change of a position of a source of the light upon detection of the pre-defined change in the light conditions.
A system comprising:
- an eye tracking device;
- and
- a computing device, wherein the system is configured to perform a method, the method comprising:
- emitting light from the eye tracking device;
- capturing one or more images with the eye tracking device of an area illuminated by said emitting the light;
- determining one or more gaze characteristics from analysis of the images with the computing device based on eye illuminations within the images from said emitting the light;
- analyzing the images with the computing device to detect a pre-defined change in lighting conditions in the images;
- and
- triggering a change with the computing device of a position of a source of the light upon detection of the pre-defined change in the light conditions.
A non-transitory computer readable medium having processor-executable instructions embodied therein, wherein execution of the instructions by a processor causes a processor to perform a method, the method comprising:
- emitting light from an eye tracking device;
- capturing one or more images with the eye tracking device of an area illuminated by said emitting the light;
- determining one or more gaze characteristics from analysis of the images based on eye illuminations within the images from said emitting the light;
- analyzing the images to detect a pre-defined change in lighting conditions in the images;
- and
- triggering a change of a position of a source of the light upon detection of the pre-defined change in the light conditions.
