  • Patent number: 9733745
    Abstract: A touch-sense device includes an overlay, such as a rough overlay or a compliant overlay, on a sensing layer. Use of the overlay changes a response of the sensing layer so that a light press is more distinguishable from a strong press by sensing electronics. Distinguishing the light press from the strong press enables the sensing electronics to report additional information in response to a press. In one example, a sensor signal of the sensing layer attains a first magnitude for a light press, and a second magnitude for a strong press, enabling the strong press to be distinguished. In another example, a sensor signal has a second edge in response to a strong press, and detection of the second edge enables the strong press to be distinguished. In various embodiments, a surface of the overlay has protrusions and/or cavities and/or is compressible.

  • Patent number: 9582077
    Abstract: A method and apparatus for providing force feedback to a user operating a human/computer interface device in conjunction with a graphical user interface (GUI) displayed by a host computer system. A physical object, such as a joystick or a mouse, controls a graphical object, such as a cursor, within the GUI. The GUI allows the user to interface with operating system functions implemented by the computer system. A signal is output from the host computer to the interface device to apply a force sensation to the physical object using one or more actuators. This desired force sensation is associated with at least one of the graphical objects and operating system functions of the graphical user interface and is determined by a location of the cursor in the GUI with respect to targets that are associated with the graphical objects. The graphical objects include icons, windows, pull-down menus and menu items, scroll bars (“sliders”), and buttons.
