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.

Video user's environment

The document browser for electronic filing systems supports pen-based markup and annotation. The user may electronically write notes anywhere on a page and then later search for those notes using the approximate ink matching (AIM) technique. The technique segments the user-drawn strokes, extracts and vector quantizes features contained in those strokes. An edit distance comparison technique is used to query the database, rendering the system capable of performing approximate or partial matches to achieve fuzzy search capability.
