Abstract
The user communicates through a digitizing writing surface with the audio/video control apparatus. An on-screen display is generated, providing the user with a user environment in which a wide range of different tasks and functions can be performed. The digitizing writing surface can be incorporated into a hand-held remote control unit and the audio/video control apparatus may likewise be incorporated into existing home entertainment or computer equipment. By tapping on the writing surface a command bar is presented on the screen, allowing the user to select among various functions. Included in these functions is an on-screen programming feature, allowing the user to select programs for viewing or recording by entry of user-drawn annotations or commands via the writing surface.
