Abstract: A method for determining a focus target of a user's gaze in a three-dimensional (“3D”) scene is disclosed. The method may include determining a first gaze direction of a user into a 3D scene, where the 3D scene includes a plurality of components. The method may also include executing a first plurality of line traces in the 3D scene, where each of the first plurality of Line traces is in proximity to the first gaze direction. The method may further include determining a confidence value for each component intersected by at least one of the first plurality of line traces. The method may additionally include identifying as a focus target of the user the component having the highest confidence value of all components intersected by at least one of the first plurality of line traces.

Abstract: According to the invention, a method for reducing aliasing artifacts in foveated rendering is disclosed. The method may include accessing a high resolution image and a low resolution image corresponding to the high resolution image, and calculating a difference between a pixel of the high resolution image and a sample associated with the low resolution image. The sample of the low resolution image corresponds to the pixel of the high resolution image. The method may further include modifying the pixel to generate a modified pixel of the high resolution image based on determining that the difference is higher than or equal to a threshold value. The modification may be made such that an updated difference between the modified pixel and the sample is smaller than the original difference.

Abstract: A method for panning content on a display of a wearable device is disclosed. The method may include determining, via an eye tracking device, a gaze direction of a user. The method may also include determining, via a movement detection system, a head direction of the user. The method may further include, based at least in part on the gaze direction and the head direction both being consistent with a particular direction, causing content displayed on a display of the wearable device to be panned in the particular direction. The method may additionally include determining during panning of the content, via the eye tracking device, that the gaze direction of the user has returned to a neutral position. The method may moreover include, based at least in part on the gaze direction of the user returning to the neutral position, causing content displayed on the display to stop panning.

Abstract: A method for determining if a user's gaze is directed in the direction of a zone of interest in a 3D scene comprises: providing a 3D scene containing a zone of interest; associating a property with the zone of interest; creating a bitmap representing the location of the zone of interest in a projected view of the 3D scene, each pixel of the bitmap to which the zone of interest is projected storing the property of the zone of interest; detecting the direction of the user's gaze; using the bitmap to determine if the detected user's gaze is directed in the direction of the zone of interest.
