  • Patent number: 11360579
    Abstract: The electronic devices described herein are configured to enhance user experience associated with using a pen on the touchscreens of the electronic devices. Contact of a pen on the touch screen is detected by a persistent, pen-aware shell that occupies some or all of the touch screen user interface throughout operation of the electronic device. Detected pen contact with the touch screen is captured/collected as pen input and used to perform a function of the electronic device or shared with an application such that the application may perform a function based on the pen input. A performed function or application with which to share the pen in put is selected by a user, automatically by an operating system, or a combination of the two. Automatic capture of pen input by the persistent, pen-aware shell provides an intuitive way of making use of pen/touch screen capability of an electronic device.

  • Patent number: 11169624
    Abstract: An apparatus includes a housing, a tip that moves with respect to the housing based on applied contact force and a pressure sensor that detects the force applied on the tip. The pressure sensor includes a first element integrated or fixed to the tip and a second element that is stationary with respect to the housing and positioned to face the first element. The first element is formed from a rigid material that is conductive. The second element is conductive and has elastic properties. In addition, one of the first element or the second element is coated with a non-conductive layer. The first element moves toward the second element based on force applied on the tip and deforms the second element based on the force. The sensor additionally includes a circuit to detect capacitance between the first element and the second element.

  • Patent number: 11163440
    Abstract: An electronic device, in response to detecting an input on a touch-sensitive surface: processes the input with a first gesture recognizer for an operating system application; and processes the input with a second gesture recognizer for a first software application, distinct from the operating system application. If the first gesture recognizer recognizes the input as a gesture matching a gesture definition of the first gesture recognizer, the device performs an operation defined by the operating system application and transitions the second gesture recognizer into an event impossible state. If the second gesture recognizer recognizes the input as a gesture matching a gesture definition of the second gesture recognizer, the device delays performance of an operation defined by the first software application for the input until the first gesture recognizer indicates that the input does not match the gesture definition of the first gesture recognizer.
