Abstract: Methods and systems for gesture recognition in an ophthalmic device are described. An example method may comprise receiving, by a first sensor system disposed on or in a first ophthalmic device, first sensor data representing a first movement of a user; determining, based on at least the first sensor data, that the first movement is indicative of a gesture mode trigger; causing, based on the gesture mode trigger, the first sensor system to enter a gesture mode; receiving, during the gesture mode, second sensor data; determining, based on the second sensor data, a second movement, wherein the second movement represents a change relative to one or more of a first axis and a second axis; determining a gesture of the user by comparing the second movement to one or more stored movements associated with corresponding gestures; and processing the gesture of the user.

Abstract: A method including receiving sensor data during a calibration sequence for one or more a first ophthalmic device or a second ophthalmic device; determining, based on the sensor data, a change in a characteristic of one or more of the first eye or the second eye, the change relates to a calibration instruction provided to the user during the calibration sequence; determining a first polarity indicating that the first ophthalmic device is disposed adjacent one of a right eye or a left eye based on the change in the characteristic of one or more of the first eye or the second eye; determining a second polarity indicating that the second ophthalmic device is disposed adjacent the other of the right eye or left eye; and associating a first identifier with the first ophthalmic device and a second identifier with the second ophthalmic device.
