Field: Optics (Instruments)
Classification: CPC G | IPC F  G

Claim 14:
15. A method of controlling a wearable electronic device, the method comprising:
measuring a first bending state between a temple and a frame using a bend sensor connected to the temple and the frame;
outputting infrared light for tracking a gaze of a user using an infrared output unit;
detecting infrared light reflected from a pupil of the user using an infrared sensor;
outputting, by a display, visible light corresponding to a virtual image;
supplying by a first control circuit, driving power and a control signal to the display;
measuring, by a second control circuit, a second bending state of a bridge based on a result of the detecting by the infrared sensor;
adjusting, by the second control circuit, a direction of the visible light using a beam steering member based on the first bending state and the second bending state;
adjusting a direction of the visible light traveling from an exit pupil of the display to an input grating of an optical waveguide using liquid crystal; and
adjusting a path of the visible light and output the virtual image and
supplying, by the second control circuit, driving power and a control signal to the infrared sensor and the infrared output unit.
