16 Claims

1. A handwriting drawing method, the method comprising:

performing, by an electronic device that comprises a touch screen, the touch screen comprising a touch panel sensor (TP sensor), a handwriting drawing operation in response to detecting that a stylus moves close to the touch screen and that a capacitance change amount of the TP sensor is greater than or equal to a first threshold; and

stopping, by the electronic device, the handwriting drawing operation in response to detecting that the stylus moves away from the touch screen and that the capacitance change amount of the TP sensor is less than a second threshold, wherein the first threshold is different from the second threshold;

wherein the first threshold when the stylus is at a first position of the touch screen is different from the first threshold when the stylus is at a second position of the touch screen;

wherein the performing the handwriting drawing operation in response to detecting that the stylus moves close to the touch screen and that the capacitance change amount of the TP sensor is greater than or equal to the first threshold comprises:

detecting a position of the stylus on the touch screen in response to detecting that the stylus moves close to the touch screen;

querying the first threshold at the first position based on that the stylus is at the first position of the touch screen; and

performing the handwriting drawing operation in response to that a capacitance change amount of the TP sensor at the first position is greater than or equal to the first threshold at the first position; and

wherein the touch screen comprises a first region and a second region, the first region comprises the first position, and the second region comprises the second position, and wherein the method further comprises:

recording the first threshold in the first region in response to detecting that the stylus is in contact with the first position; and

recording the first threshold in the second region in response to detecting that the stylus is in contact with the second position.
