Abstract

See full text

A depth sensing system is configured to track one or both eyes of a user. The depth sensing system includes a transducer chip comprising a phased array of ultrasound transducers that transmit a signal at an eye of the user and detect a reflected signal from the eye. A controller estimates an orientation of the eye based on the reflected signals received by the phased array. The depth sensing system may be part of a headset that includes a display element configured to display content to a user wearing the headset.
