Abstract: An electronic device and a touch operating method thereof are provided. The electronic device includes a touch screen, a storage unit and at least one processing unit, and the touch operating method includes following steps. A touch object above the touch screen is detected by using the touch screen, and a distance between the touch object and the touch screen is estimated. A relative angle of a pointing direction of the touch object with respect to a normal direction of the touch screen is detected. According to the distance and the relative angle, a function is performed on an object displayed by the touch screen.

Abstract: A method for providing a haptic feedback is provided. The method includes sending out a stylus activation signal by a stylus when the stylus enters an active state. The method also includes receiving the stylus activation signal by an electronic device, and transmitting a corresponding feedback effect signal to the stylus by the electronic device while an event to be notified occurs. The method further includes providing the haptic feedback in accordance with the feedback effect signal by the stylus.

Abstract: The present invention provides an electronic device including a display, an input detection module and a processor. The input detection module detects an operation on the display executed by an indication electronic device, and generates a first operation signal corresponding to location information of the operation. The processor receives an enable signal from the indication electronic device, and then determines that the electronic device and the indication electronic device are in a first communication mode or a second communication mode. In the first communication mode, the processor obtains a first file corresponding to the location information and stores the first file to the indication electronic device by the communication module. In the second communication mode, the processor obtains a second file from the indication electronic device by the communication module and displays it on the position corresponding to the location information of the display.
