Abstract: An edge detection circuit receives a detector signal from an infrared detector positioned and oriented to detect reflections of infrared light from a scan area including at least a portion of an eye, detects an edge of at least one feature of the eye from the detector signal, and outputs information about a position of the edge of the feature relative to the scan area.

Abstract: System and methods are disclosed for dynamically generating scene-based content on a wearable heads-up display having a field of view. The method includes capturing a sequence of images of an environment of the wearable heads-up display, presenting the feed in a display space in the field of view of the wearable heads-up display, persistently displaying of the captured images in the display space in response to a scene selection request that identifies a selected scene, receiving a selection that indicates a target area in the persistently displayed captured image, processing the target area to identify one or more objects in the selected scene. Display content is generated based at least in part on the one or more objects identified in the selected scene. The display content is presented in the display space.
