  • Patent number: 9766723
    Abstract: Techniques are disclosed for performing stylus-based actions in electronic devices without the stylus having to touch the stylus detection surface. A stylus action may include manipulating one or more control features of the stylus, and each control feature action or combination of actions may be associated with distinct functions. The device may detect, for example, whether the stylus is pointing to specific content or one or more UI control features or icons on the device, for which a corresponding function can be performed. In other cases, functions can be performed without reference to specific content. The device may track stylus location over the detection surface and the non-touch stylus action may be location sensitive. The various functions assigned to non-touch stylus actions may be performed on an application specific level, or a global device level. An animation can be displayed as non-touch stylus actions are executed.

  • Patent number: 9760187
    Abstract: Styluses with active color indicator functionality are disclosed. The styluses are intended for use with a touch sensitive device. The active color generally refers to the color currently in use by the touch sensitive device, such as in a virtual drawing or note taking application. Active colors can be selected using the touch sensitive device and/or the stylus itself. When the active color is selected using the touch sensitive device, the stylus receives the active color information and indicates the color on the stylus (e.g., via a correspondingly colored LED or LCD or a color rotation mechanism). When the active color is selected from the stylus itself, that color is indicated on the stylus and active color information is transmitted to the touch sensitive device. The active color can be displayed such that it is detectable regardless of stylus position (e.g., no blind spots).
