Classification: CPC G | IPC F  G

Claim 7:
8. A wearable electronic device, comprising:
a skeletal member comprising a temple, a frame, and a bridge;
a self-luminous display fixed to the temple and comprising a plurality of visible-light pixels configured to output visible light corresponding to a virtual image and a plurality of infrared pixels configured to output infrared light;
a beam steering member comprising a liquid crystal and configured to adjust a direction of the visible light traveling from an exit pupil of the self-luminous display to an input grating of an optical waveguide using the liquid crystal;
an optical waveguide configured to adjust a path of the infrared light to output the infrared light to a pupil of a user and adjust a path of the visible light to output the virtual image;
an infrared sensor configured to detect infrared light reflected from the pupil of the user;
a bend sensor connected to the temple and the frame, the bend sensor configured to measure a first bending state between the temple and the frame;
a first control circuit configured to supply driving power and a control signal to the self-luminous display; and
a second control circuit configured to: measure a second bending state of the bridge based on a result of the detecting by the infrared sensor, and adjust the direction of the visible light through the beam steering member based on the first bending state and the second bending state.
