发明名称 PEN INTERFACE FOR A TOUCH SCREEN DEVICE
摘要 A system and method that allows pen input and touch input to better co-exist during writing on a touch screen device, such as a tablet device. If the pen/stylus is detected as present and is pointed at the surface, inputs initiated by a user's finger (or other) touch are rejected and pen inputs are allowed. If the pen is detected as present, but is pointed away from the writing surface of the touch screen, stylus/pen inputs are rejected and touch inputs are allowed. If pen is not detected as present, the system ignores all pen inputs. Erasing functions are also provided. The size of the eraser can be made proportional to the pressure level, contact size or signal level of the pen or the user's finger performing the erasing.
