Handwritten keyboardless-entry computer system. |
摘要 |
<p>A keyboardless-entry computer system includes a transparent input screen (18) that generates positional information when contacted by a stylus, and a display screen (20) mounted physically below the input screen such that a character that is displayed can be seen below the input screen. The system includes a computer (14) programmed to compile the positional information into Strokes, to calculate Stroke characteristics, and then compare the Stroke characteristics with those stored in a database in order to recognise the symbol drawn by the stylus. Key features of the system are: (A) transparent position sensing subsystem; (B) underlying display on which to mimic drawing of sensed positions and to shown characters or symbols; (C) means to convert sensed positions first into plotted Points and then into recognised characters or symbols; and (D) means to "learn" to associate sensed input positions with a character or symbol.</p> |
