Abstract

A method in an electronic device, the method includes projecting infrared (“IR”) light from a plurality of light emitting diodes (“LEDs”) disposed proximate to the perimeter of the electronic device, detecting, by a sensor, IR light originating from at least two of the plurality of LEDs reflected from off of a person, and carrying out a function based on the relative strength of the detected IR light from the LEDs.

Claims

causing light to be projected from a plurality of light sources;

detecting, using a sensor, light originating from at least two light sources of the plurality of light sources that is reflected from an eye of a user of the electronic device;

generating at least one signal based on the detected light;

determining movement of the eye based on the at least one signal; and

carrying out a function on the electronic device based on the at least one signal.

2. The method of claim 1, wherein the carrying out a function on the electronic device comprises carrying out a function on the electronic device based on relative strength of the detected light originating from the at least two light sources.

3. The method of claim 2, further comprising reselecting at least one light source of the plurality of light sources if the detected light originating from at least one of the at least two light sources becomes weaker than detected light originating from the at least one light source.

4. The method of claim 2, further comprising:

determining, based on the relative strength of the detected light, a difference between detected light originating from at least one light source of the at least two light sources having a stronger detected light and detected light originating from at least one light source of the at least two light sources having a weaker detected light; and

causing an increased amount of light to be projected from the at least one light source from which the weaker detected light originated based on the determined difference.
