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.
