    摘要: A mobile telephone includes an active-pixel sensor in conjunction with a DSP chipset and a light source allowing the telephone to detect horizontal movement across a flat surface. When moved horizontally, the telephone detects relative position movement and transmits a new position to a nearby computer. The computer interprets this new position as a cursor control position and moves its cursor. The telephone is placed into a mode such that physical buttons or displayed buttons on a touch screen operate as a mouse click when pressed. The mouse click is interpreted by the telephone and transmitted to the computer to affect the mouse click. The telephone is also placed into a mode such that raising it from the flat surface indicates that a subsequent three-dimensional movement is interpreted as a mouse click. A shake, rotation or sharp movement is interpreted as a mouse click which is transmitted to the computer to implement the mouse click in conjunction with its cursor.
