Abstract: A method for determining a force of a touch object on a touch device and for determining its related touch event is provided. The touch object touched on the touch device is clustered into different object groups. Thus, multiple touch objects are simply grouped into two object groups to easily calculate the pressing force that is provided for determining follow-up touch event.

Abstract: A touch device and an operation method thereof is provided. By determining whether the operating event of the touch device or its touchpad satisfies an exclusion condition, the command triggered when the touchpad is pressed is determined to be ignored or not. Therefore, the corresponding command triggered by pressing the touchpad downward is automatically excluded when it does not want to be triggered. Therefore, the user can naturally disable the function of the corresponding command, which is executed when the pressing module is triggered, during use without using other controls, thereby improving the convenience of use.
