  • Patent number: 10613666
    Abstract: Content can be using an input device without a touch-sensitive surface. In some examples, touch-down and lift-off on a non-touch-sensitive surface can be monitored by a force sensor of the input device. The position and/or motion of the input device can be tracked according to various methods including one or more of a motion and orientation sensor, a camera, or an electromagnetic- or sound-based triangulation scheme. The force data and position/motion data can be processed to generate content, including textual character input and three-dimensional objects. In some examples, the content can be generated based on tracking position and/or motion of the input device without requiring contact with a surface.

  • Patent number: 9977518
    Abstract: Improved approaches for users to interact with graphical user interfaces of computing devices are disclosed. A rotational user action supplied by a user via a user input device can provide accelerated scrolling. The accelerated nature of the scrolling enables users to scroll or traverse a lengthy data set (e.g., list of items) faster and with greater ease. The amount of acceleration provided can be performed in successive stages, and/or performed based on the speed of the rotational user action. In one embodiment, the rotational user action is transformed into linear action with respect to a graphical user interface. The resulting acceleration effect causes the linear action to be enhanced such that a lengthy data set is able to be rapidly traversed.

  • Patent number: 9965056
    Abstract: The present disclosure provides systems and methods for receiving an input signal from a touch-sensitive interface via a first electrode associated with a tip of an active stylus. An input signal may be amplified via a control circuit that adjusts the gain of one or more amplifiers to compensate for changes in tip capacitance between the tip of the active stylus and the touch-sensitive interface. Changes in tip capacitance may be indirectly detected and compensated for by comparing the tip capacitance with that of a reference capacitor via a differential amplification circuit that includes one or more differential amplifiers.

  • Patent number: 9958991
    Abstract: An input device and an input method for a data processing device are provided. The input device includes a touch-sensitive module, an operation prompt interface and a controller. According to the input method, the input device issues a first input signal to the data processing device when a first electrical property change resulting from the keystroke or the tap is sensed in a first operation state. The input device is switched from the first operation state to a second operation state in response to a switching operation. The input device issues a second input signal to the data processing device when a second electrical property change resulting from a touch action is sensed in the second operation state.

  • Patent number: 9946408
    Abstract: In one embodiment, a system comprises a stylus and a touch sensor. The stylus is operable to transmit a first signal. The touch sensor comprises a first plurality of electrode lines and a controller. Each electrode line is operable to sense the first signal transmitted by a stylus. The stylus tip of the stylus is located at a position relative to the first plurality of electrode lines at the time of transmission of the first signal. The controller is operable to measure a voltage, charge, or capacitance of the sensed first signal on each electrode line of the first plurality of electrode lines and estimate the position of the stylus tip based on interpolation of the measured voltages on each electrode line of the first plurality of electrode lines.

  • Patent number: 9946365
    Abstract: Techniques are disclosed for interacting with a computing device using a stylus. The stylus is configured with a pressure-sensitive control feature that can be activated to perform various actions while the stylus is touching or otherwise sufficiently proximate to a stylus detection surface of the device. The pressure control feature function can be associated with a variety of tasks on the computing device such as: adjusting variables, executing a particular command, switching between tools, modifying a particular tool's settings, and launching an application. In some embodiments, the stylus-based pressure-sensitive control feature is configured to allow for squeeze actions, tapping actions, and various combinations of such pressure-types on the pressure-sensitive control feature to uniquely identify a corresponding function to be carried out on the computing device.
