Abstract: According to the invention, a system for presenting graphics on a display device is disclosed. The system may include an eye tracking device for determining a gaze point of a user on a display device. The system may also include a graphics processing device for causing graphics to be displayed on the display device. The graphics displayed on the display device may be modified such that the graphics in an area including the gaze point of the user have at least one modified parameter relative to graphics outside the area. The size of the area may be based at least in part on an amount of noise in the gaze point over time and at least one other secondary factor.

Abstract: A method for determining correspondence between a gaze direction and an environment around a wearable device is disclosed. The wearable device may include an eye tracking device and an outward facing image sensor. The method may include receiving an input parameter and at least one scene image from the outward facing image sensor. The method may further include determining, with at least the eye tracking device, at least one gaze direction of a wearer of the wearable device at a point in time corresponding to when the scene image was captured by the outward facing image sensor. The method may additionally include determining, based at least in part on the input parameter, that a particular scene image includes at least a portion of a predefined image. The method may moreover include determining, based on the at least one gaze direction, at least one gaze point on the particular scene image.
