  • Publication number: 20160026270
    Abstract: An operating method of an electronic apparatus and a touch apparatus are provided. In the method, a touch action by a user on a touch panel is detected through a controller of the touch apparatus, so as to obtain a contact region touched by the touch action on the touch panel. Subsequently, whether the touch action includes a palm touch is determined based on a size of the contact region. Under the situation that the touch action includes the palm touch, palm touching information corresponding to the palm touch is transformed into mouse controlling information through a mouse simulating device of the touch apparatus. Further, the mouse controlling information is sent to a mouse driver through the mouse simulating device, such that the mouse driver executes mouse operation based on the mouse controlling information.
