  • Control system for a touch device and method thereof
    Patent number: 11320927
    Abstract: A control system applicable to a touch device is provided. The touch device includes a touch sensor. The control system comprises a sensing circuit, configured to sense the touch sensor and generate a plurality of sensing values; a processor, configured to generate a sensing image according to the plurality of sensing values; and a convolutional neural network, configured to process the sensing image to generate feature information and generate identification information according to the feature information for determining a status of the touch sensor.
    Type: Grant

  • Method of changing identified type of touching object
    Patent number: 10691257
    Abstract: A method of changing the identified type of a touching object is provided. The touching object is on a touch pad. The method includes the following steps: (A) when the type of the touching object is determined as a palm, determining the type of the touching object again; (B) when the type of the touching object is determined as a finger in step (A), informing the operating system that the touching object has left the touch pad when the touching object does not leave the touch pad; and (C) after step (B) is done, informing the operating system that the type of the touching object is a finger.
