Visibility improvement method based on eye tracking, machine-readable storage medium and electronic device

A non-transitory machine-readable storage medium having a program recorded thereon, which when executed, performs a method of improving visibility using gaze tracking, the method comprising:

• detecting a gaze of a user using a camera;
• determining a focus object at which the user gazes from among at least one object;
• transmitting, to a server, an image including the focus object and information associated with the focus object, wherein the information associated with the focus object includes at least one of location information of the electronic device and direction information of the electronic device;
• receiving, from the server, an image retrieved from storage by the server that corresponds to the focus object and has higher visibility than the transmitted image;
• and
• displaying, on a display unit, the retrieved image.

An electronic device, comprising:

• a camera that photographs an eye of a user;
• a display unit that displays at least one object;
• and
• a controller configured to:
• detect a gaze from the photographed eye of the user,
• determine a focus object at which the user gazes from among the at least one object,
• transmit, to a server, an image including the focus object and information associated with the focus object, wherein the information associated with the focus object includes at least one of location information of the electronic device and direction information of the electronic device,
• receive, from the server, an image retrieved from storage by the server that corresponds to the focus object and has higher visibility than the transmitted image, and
• display, through the display unit, the retrieved image.

A wearable electronic device, comprising:

• a housing for positioning the wearable electronic device on a user's body;
• at least one camera that photographs an eye of the user;
• at least one display unit that displays at least one object;
• and
• a controller configured to:
• detect a gaze from the photographed eye of the user,
• determine a focus object at which the user gazes from among the at least one object,
• transmit, to a server, an image including the focus object and information associated with the focus object, wherein the information associated with the focus object includes at least one of location information of the electronic device and direction information of the electronic device,
• receive, from the server, an image retrieved from storage by the server that corresponds to the focus object and has higher visibility than the transmitted image, and
• display, through the display unit, the retrieved image.
