Abstract: Examples relating to attracting the gaze of a viewer of a display are disclosed. One example method comprises controlling the display to display a target object and using gaze tracking data to monitor a viewer gaze location. A guide element is displayed moving along a computed dynamic path that traverses adjacent to a viewer gaze location and leads to the target object. If the viewer's gaze location is within a predetermined divergence threshold of the guide element, then the display continues displaying the guide element moving along the computed dynamic guide path to the target object. If the viewer's gaze location diverts from the guide element by at least the predetermined divergence threshold, then the display discontinues displaying the guide element moving along the computed dynamic guide path to the target object.

Abstract: Embodiments are disclosed for eye tracking systems and methods. An example eye tracking system comprises a plurality of light sources and a camera configured to capture an image of light from the light sources as reflected from an eye. The eye tracking system further comprises a logic device and a storage device storing instructions executable by the logic device to acquire frames of eye tracking data by iteratively projecting light from different combinations of light sources of the plurality of light sources and capturing an image of the eye during projection of each combination. The instructions may be further executable to select a selected combination of light sources for eye tracking based on a determination of occlusion detected in the image arising from a transparent or semi-transparent optical structure positioned between the eye and the camera and project light via the selected combination of light sources for eye tracking.

Abstract: A method to furnish input representing gaze direction in a computer system operatively coupled to a vision system. In this method, a first image of an eye at a first level of illumination is acquired by a camera of the vision system. The first image is obtained from the camera, and a second image of the eye corresponding to a second, different level of illumination is also obtained. Brightness of corresponding pixels of the first and second images is compared in order to distinguish a reflection of the illumination by the eye from a reflection of the illumination by eyewear. The input is then furnished based on the reflection of the illumination by the eye.

Abstract: Examples relating to using non-visual feedback to alert a viewer of a display that a visual change has been triggered are disclosed. One disclosed example provides a method comprising using gaze tracking data from a gaze tracking system to determine that a viewer changes a gaze location. Based on determining that the viewer changes the gaze location, a visual change is triggered and non-visual feedback indicating the triggering of the visual change is provided to the viewer. If a cancel change input is received within a predetermined timeframe, the visual change is not displayed. If a cancel change input is not received within the timeframe, the visual change is displayed via the display.
