Abstract
An eye-tracking electronic device is provided. The eye-tracking electronic device includes a scanner, at least two photodetectors configured to generate electric pulses when a scanning line reflected from a cornea is incident thereon, and at least one processor configured to generate at least one scanning line through the scanner, radiate the at least one scanning line to the cornea, and determine a direction of gaze based on time information when the at least two photodetectors generate the electrical pulses.
Claims15
An eye-tracking electronic device comprising:
- a scanner;
- at least two photodetectors configured to generate electric pulses when a scanning line reflected from a cornea is incident thereon;
- and
- at least one processor configured to:
- generate at least one scanning line through the scanner,
- radiate the at least one scanning line to the cornea, and
- determine a direction of a gaze based on time information when the at least two photodetectors generate the electrical pulses,
- wherein the scanner comprises:
- a light source configured to generate the at least one scanning line;
- an optical element configured to convert the at least one scanning line to form a scanning area of a linear shape, having a length from an upper eyelid to a lower eyelid, perpendicular to a scanning direction;
- and
- a single-axis scanner mirror configured to rotate relative to one axis to move the scanning area.
A method, performed by an eye-tracking electronic device, of determining a direction of a gaze, the method comprising:
- generating, by a scanner, at least one scanning line;
- radiating the at least one scanning line to a cornea;
- generating, by at least two photodetectors, electric pulses when the at least one scanning line is reflected from the cornea to be incident thereon;
- and
- determining the direction of the gaze based on time information when the electrical pulses are generated,
- wherein the scanner comprises:
- a light source configured to generate the at least one scanning line;
- an optical element configured to convert the at least one scanning line to form a scanning area of a linear shape, having a length from an upper eyelid to a lower eyelid, perpendicular to a scanning direction;
- and
- a single-axis scanner mirror configured to rotate relative to one axis to move the scanning area.
A computer program product comprising a non-transitory computer-readable recording medium having recorded thereon a program for executing a method, performed by an eye-tracking electronic device, of determining a direction of a gaze, the method comprising:
- generating, by a scanner, at least one scanning line;
- radiating the at least one scanning line to a cornea;
- generating, by at least two photodetectors, electric pulses when the at least one scanning line is reflected from the cornea and is incident thereon;
- and
- determining the direction of the gaze based on time information when the electrical pulses are generated,
- wherein the scanner comprises:
- a light source configured to generate the at least one scanning line;
- an optical element configured to convert the at least one scanning line to form a scanning area of a linear shape, having a length from an upper eyelid to a lower eyelid, perpendicular to a scanning direction;
- and
- a single-axis scanner mirror configured to rotate relative to one axis to move the scanning area.
