1. A mobile phone for controlling a pointer, comprising:
- a touch screen;
a storage unit for storing position information and direction information on the touch screen and function applications associated with the position or the direction information;
a display unit;
a screen optical sensing unit for sensing light blocked by a finger on the touch screen in real time and forming a light spot on the touch screen corresponding to the finger to generate a light source signal; and
a control unit for calculating coordinates of the light spot and obtaining the position of the light spot on the touch screen according to the light source signal, generating a pointer on the position of the light spot and displaying the pointer on the touch screen, evaluating whether an operation is received on the pointer position from the finger, when the pointer position receives the operation, acquiring a function application for the operation on the pointer position from the storage unit, and performing a function associated with the function application.

Abstract
The disclosure provides a mobile phone with pointer and a pointer control method adapted for the mobile phone. When a user finger over a touch screen is within a predetermined distance, a position of the touch screen corresponding to the user finger displays a pointer. When the finger moves over the touch screen within the predetermined distance, the pointer on the touch screen moves with the finger moving. When the user generates an operation on the touch screen and presses/slides the position of the pointer, the mobile phone performs a function corresponding to the operation.
