Abstract: A system includes an electronic contact lens that can detect eye gestures for initiating various actions. The electronic contact lens includes integrated sensors for obtaining sensor measurements characterizing eye motion. The sensor measurements are processed to detect gestures mapped to specific actions such as changing a power state of the electronic contact lens, activating or deactivating a user interface or other feature, or selecting an item from a virtual menu. The eye gestures may involve the user sequentially performing a first saccade quickly followed by a second saccade in an opposite direction from the first saccade.

Abstract: A system includes an electronic contact lens that obtains sensor measurements from integrated motion sensors or other types of sensors and a processing module that estimates a mental state of an individual based on the sensor measurements. The processing module identifies patterns of eye movements and analyzes how these patterns change over time. Based on anatomical relationships between eye movement and mental state, the processing module estimates characteristics of the individual such as fatigue, intoxication, injury, or a medical condition that have known effects on eye movement patterns. The electronic contact lens system generates an output indicative of the estimated mental state to alert the individual to the detected condition or to initiate an automated action.

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 an electronic contact lens that can detect eye gestures for initiating various actions. The electronic contact lens includes integrated sensors for obtaining sensor measurements characterizing eye motion. The sensor measurements are processed to detect gestures mapped to specific actions such as changing a power state of the electronic contact lens, activating or deactivating a user interface or other feature, or selecting an item from a virtual menu. The eye gestures may involve the user sequentially stabilizing at a starting pitch, executing a first motion that crosses a first pitch threshold, executing a second motion that crosses a second pitch threshold in an opposite direction from the starting pitch, and stabilizing at an ending pitch.

Abstract: An imaging device contained in a contact lens captures images of the external environment, which for convenience will be referred to as real-world images. These real-world images are used to stabilize images produced by a femtoprojector also in the contact lens. For convenience, the images produced by the femtoprojector will be referred to as augmented reality or AR images. The femtoprojector is inward-facing (i.e., facing towards the interior of the eye) and projects the AR images onto the user's retina, creating the appearance of virtual images in the external environment. The imaging device, referred to as a femtoimager for convenience, is outward-facing and captures a sequence of actual real-world images of the external environment. Because the femtoimager and femtoprojector move together, the real-world images captured by the femtoimager reflect the motion of the virtual AR images from the femtoprojector relative to the external environment.

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.
