An electronic device includes an infrared temperature sensor and can detect a user's finger arranged within a detection distance even though the user's finger does not contact the electronic device. Movement of the user's finger is also detected. A pointer positioned and moving according to the position and movement of the user's finger is displayed on a screen of the portable electronic device, and a predetermined function corresponding to the movement of the finger may be performed. A method for controlling the electronic device includes detecting that a user's finger is positioned within a detection distance of an infrared temperature sensor, and displaying a pointer corresponding to a position of the user's finger on a display screen. The method also may include moving the pointer or performing a function corresponding to the movement direction of the pointer.
