  • Patent number: 12340070
    Abstract: A method for providing selectable quick actions on handwritten data in a handwritten document is disclosed. The method includes fetching the handwritten data corresponding to strokes made by a user in the handwritten document and recognizing text associated with the received handwritten data by employing a handwriting recognition technique. The method also includes identifying keywords in the recognized text and classifying each identified keyword into an entity type by employing a named entity recognition, a named entity linking, and/or a knowledge graph. In some embodiments, the method includes determining actionable items associated with the classified entity type corresponding to each keyword and creating quick actions, selectable by the user, for each keyword based on the determined actionable items via the knowledge graph. The method includes rendering the created quick actions associated with each keyword on the handwritten document based on a profile associated with the user.

  • Patent number: 12327000
    Abstract: Disclosed herein is a touch state detection circuit which is connected to a capacitance-type touch sensor including sensor electrodes disposed in a planar manner and which detects a touch state of a user by executing a scan process that reads out and processes detection signals sequentially output from the sensor electrodes. The touch state detection circuit includes a setting circuit which sets a scan condition related to an execution frequency of the scan process or an execution period of the scan process, and a detection circuit which detects the touch state by executing the scan process under the scan condition set by the setting circuit. When a determination condition indicating a situation in which the scan condition is required to be changed is satisfied, the setting circuit changes and resets the scan condition, and the detection circuit detects the touch state under the scan condition reset by the setting circuit.
