Abstract
Optomechanical alignment decay occurs in wearable eye sensors when frames shift during physical movement. Rigidly mounted forward lenses also transmit footstep impact vibrations, causing image distortion. In this disclosure, an electromechanically adjustable dual-camera eyewear device is provided with independent micro-gimbal assemblies. An outward-facing camera module and an inward-facing camera module are coupled to linear piezoelectric micro-actuators for vertical pitch and horizontal yaw positioning. Closed-loop calibration signals drive micro-actuator adjustments to re-center the inward-facing lens upon pupil displacement. Motion telemetry from an onboard inertial measurement unit triggers antiphase micro-actuator compensation during physical movement. Full-resolution point-of-view imagery is maintained without field-of-view cropping, and a consistent gaze vector is established for directional telemetry output to external devices.
