摘要： 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.

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.

摘要： 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.

摘要： A transmitter coil inductively couples to a receiver coil contained in a contact lens. In one approach, the transmitter coil is contained in a headgear, for example a head band. When the user wears the headgear, the transmitter coil is positioned on a side of the user's head and between the user's ear and the user's eye opening. In one implementation, a head band loops from one ear behind the user's head to the other ear, and also extends slightly forward of each ear. The transmitter coil(s) may be located in the portion of the headband that extends forward of each ear. This places the transmitter coil close to the receiver coil, typically within 40-50 mm of the user's eye opening, while still maintaining an unobtrusive aesthetic.

摘要： Presented are eye-controlled user-machine interaction systems and methods that, based on input variables that comprise orientation and motion of an electronic contact lens, assist the wearer of the contact lens carrying a femtoprojector to control and navigate a virtual scene that may be superimposed onto the real-world environment. Various embodiments provide for smooth, intuitive, and naturally flowing eye-controlled, interactive operations between the wearer and a virtual environment. In certain embodiments, eye motion information is used to wake a smart electronic contact lens, activate tools in a virtual scene, or any combination thereof without the need for blinking, winking, hand gestures, and use of buttons.

摘要： 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.

摘要： 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.

摘要： 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.
