  • Patent number: 6473006
    Abstract: A method and apparatus to provide users with enhanced visual feedback after entry of data. When a user activates a key or inputs a sequence of keystrokes, a corresponding data character or characters is determined and displayed in a highlighting window. The desired character or set of characters may be determined by a predictive data entry method. The highlighting window provides greater visual feedback to the user through magnification, reverse video, or some other form of contrast enhancement method. If the user scrolls to a new character or characters because the currently displayed one(s) are not desired, then the new character or characters are displayed in the highlighting window. When the user ceases scrolling, indicating that the currently displayed character or characters are what the user desires, the highlighting window disappears and the display of the selected character or characters is restored to be the same format as previously entered characters.
