Abstract
A portable electronic device and method executes control functions by variations of a light intensity. The portable electronic device comprises a memory, a touch screen, a proximity sensor and at least one processor. The light sensor detects an original light intensity and a current light intensity surrounding the portable electronic device when the touch screen is turned on. If a difference in light intensity between the original light intensity and the current light intensity is more than a predetermined value, the portable electronic device controls a user interface displayed in the touch screen accordingly.
Claims15
A portable electronic device, comprising:
- a memory;
- at least one processor;
- a touch screen;
- a light sensor;
- a proximity sensor;
- a comparison module operable to calculate a difference of light intensity between a current light intensity and an original light intensity detected by the light sensor in response to an object being proximate to the proximity sensor;
- and
- a control module operable to control a user interface displayed in the touch screen according to the difference of light intensity.
A method for controlling a portable electronic device, the portable electronic device comprising a touch screen, a proximity sensor, a light sensor and at least one processor, the method comprising:
- detecting an original light intensity surrounding the portable electronic device using the light sensor when the touch screen is turned on;
- determining if an object is proximate to the proximity sensor;
- detecting a current light intensity surrounding the portable electronic device using the light sensor within a preset time interval in response to the object being proximate to the proximity sensor;
- calculating a difference of light intensity between the current light intensity and the original light intensity;
- and
- controlling a user interface displayed in the touch screen according to the difference of light intensity.
A storage medium having stored thereon instructions that, when executed by a processor, causes the processor to perform a method for controlling a portable electronic device, the portable electronic device comprising a touch screen, a proximity sensor, a light sensor and at least one processor, the method comprising:
- detecting an original light intensity surrounding the portable electronic device using the light sensor when the touch screen is turned on;
- determining if an object is proximate to the proximity sensor;
- detecting a current light intensity surrounding the portable electronic device using the light sensor within a preset time interval in response to the object being proximate to the proximity sensor;
- calculating a difference of light intensity between the current light intensity and the original light intensity;
- and
- controlling a user interface displayed in the touch screen according to the difference of light intensity.
