    摘要： A stylus includes a stylus housing that contains a location-beacon transmitter, a wireless receiver, and a control circuit that operably couples to the preceding. By one approach the control circuit is configured to use the location-beacon transmitter to transmit signals as a function of at least one signal received via the wireless receiver. The aforementioned wireless receiver can comprise a Bluetooth™-compatible wireless transceiver that pairs with the corresponding display-based device. The signal received via this wireless receiver can comprise transmission-synchronization information that represents a video-display event for the display-based device such as refreshing the display of the display-based device. In such a case, the signal can comprise a vertical synchronization pulse as sourced by the display-based device. So configured, the stylus can time the transmission of its location-beacon signals to arrive at the display-based device just prior to when the latter refreshes its display.

    摘要： An electronic device, computer-readable medium and method provide for line smudging in electronic drawing. The electronic device has a touch sensitive display screen that is responsive to user touch and stylus input. A graphics module is operable to render a line on the touch sensitive display screen in response to motion of the stylus. If a trajectory of the touch input intersects with the line within a set time period after the line is rendered, the line is replaced by a representation of a smudged line. The electronic device may be controllable by instructions stored on a computer-readable medium.

    摘要： The present disclosure provides for method and apparatus for controlling an application executed on an electronic device dependent upon the orientation of a stylus. The stylus includes a rotation rate sensor, such as a gyroscope. A signal, dependent on the rotation rate, is transmitted from the stylus and received by the electronic device. The stylus orientation may be determined from the rotation rate using an integration circuit to determine a rotation matrix that is applied to an initial orientation vector. The electronic device may use the stylus orientation to determine the handedness of a user, to control properties of a drawing application, or for other purposes.
