Abstract: An augmented reality system recognizes objects in a user's environment and operates an electronic contact lens based on the recognition. The electronic contact lens includes an integrated femtoimager that captures images corresponding to the user's gaze direction. The augmented reality system recognizes objects in the images and generates visual information relevant to the recognized objects that is presented using a femtoprojector integrated with the electronic contact lens. The visual information may include virtual control elements that the user can interact with to control smart devices. The augmented reality system can also configure various calibration parameters of the electronic contact lens based on a recognized environment associated with the recognized objects.

Abstract: Operation of an electronic contact lens takes into account saccadic motion of the eye and reduced visual perception during saccades (saccadic suppression). The user's eye motion is tracked, and onset of a saccade is detected based on the eye's motion. For example, saccades may be detected when the eye's acceleration or jerk exceeds a threshold. The endpoint of the saccade is then predicted in real-time while the saccade is still occurring. This may be the temporal endpoint (i.e., when the saccade ends) and/or the positional endpoint (i.e., the eye position at the end of the saccade). Operation of the electronic contact lens is adjusted based on the predicted endpoint.

Abstract: A system includes a pair of electronic contact lenses that obtain respective motion sensor measurements in response to eye movements. A tracking module derives estimated orientations for both eyes based on the sensor measurements and a set of correlations and constraints that describe human eye movement. The model describes the limited number of ways that an individual eye can move and relationships between relative movement of the left and right eye. The tracking module performs filtering based on the measurements and the eye model to suppress noise and generate orientation estimates for both eyes.
