  • Publication number: 20210089163
    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.

  • Publication number: 20110018828
    Abstract: A touch device for multi-touch environment generates a sensing signal in response to an object touch thereon, generates an event signal according to the sensing signal and a control signal, generates a cursor signal according to coordinate information of each touch point contained in the sensing signal and the event signal, and transmits the cursor signal and the event signal to the multi-touch environment. The cursor signal is used to control a cursor application to show a cursor at a screen for each touch point and changes appearances of the cursors. The cursors clearly inform a user of locations where his/her fingers correspond on the screen. By conducting touch events in the multi-touch environment through the cursors instead of actual fingers, the user can operate the touch device other than a touch screen in a multi-touch manner as operating a multi-touch screen.
