1. A wearable electronic device, comprising:
a skeletal member comprising a temple, a frame, and a bridge;
a display fixed to the temple and configured to output visible light corresponding to a virtual image;
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 display to an input grating of an optical waveguide using the liquid crystal;
the optical waveguide configured to adjust a path of the visible light and output the virtual image;
an infrared output unit configured to output infrared light for tracking a gaze of a user;
an infrared sensor configured to detect infrared light reflected from a 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 display; and
a second control circuit configured to: supply driving power and a control signal to the infrared sensor and the infrared output unit, 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.
