  • Patent number: 9696819
    Abstract: A stylus comprises a barrel having a scribing nib disposed at one end thereof. The barrel supports at least one multi-level force-sensitive user interface. A control circuit operably couples to this control surface and responds differently to each of at least two different levels of applied force as applied to that control surface. For example, the control circuit can respond to one level of applied force by causing the transmission of a first signal to influence in a first way the scribing interaction between the stylus and the scribing surface and can respond to a second, different level of applied force by causing the transmission of a second, different signal to influence in a second, different way the scribing interaction between the stylus and the scribing surface.

  • Patent number: 9335837
    Abstract: Systems, methods and computer program products for providing a text sensitive backspace key for bi-directional content are disclosed. Such systems, methods and computer program products provide a multi-stage text flow identification approach that combines desirable aspects of tracking a chronological position of typed characters as well as a cursor within bi-directional content. A directional orientation of a backspace key is thereafter manipulated on a keyboard that is both reliable and intuitive for users of a computing system. Thus, when a last-typed character, chronologically positioned immediately before the cursor, is a left-to-right (LTR) character (e.g., English language text), the backspace key is displayed in a first direction. When the last-typed character is a right-to-left (RTL) character (e.g., Hebrew language text), the backspace key is displayed in a second direction. Advantageously, the user visually learns which character will be deleted when the backspace key is pressed on the keyboard.
