摘要： A display device (5) has a touch pad (1) and a display (3) lamintated together to form a screen. That screen is connected to a controller (4) which processes signals generated by physical contact with the touch pad (1) and activates the display (3) to display e.g. characters input by a stylus (2) to the touch pad (1). The display device (5) is connected to an external device (e.g. a computer) (6) and video signals from the external device (6) are received via a video input (52) and may be displayed on the display (3). Also the controller (4) can transmit to the external device (6) via an output (51). Thus, the display can (3) display simultaneously informaion from the external device (6) and information input to the touch pad (1). If the controller (4) is arranged to carry out character recognition, the display device (5) may then act as a hand-writing input device, with the hand-written information being incorporated with information in the external device (6) and displayed.

摘要： A system using an input integrated flat panel display (5) of an integrated structure, having an input device (3, 13) for inputting through handwriting characters, graphics, or points and a flat panel display (2,12) laid upon the input device for displaying in accordance with an input point data input through handwriting. The frame memory (23) of a large screen having a display screen larger than that of the flat panel display is arranged to be read out through the input device of the input integrated flat panel display. In addition, the read-out contents of the large screen frame memory is arranged to be copied onto the flat display of the input integrated flat panel display. The input integrated flat panel display system can improve the man-machine performance while the amateur end user performs document processings, graphic processings and the like.

摘要： Coordinates of a handwritten pattern drawn on a tablet (100) are sequentially sampled by a pattern recognition unit (200) to prepare pattern coordinate data. Based on an area encircled by segments created by the sampled pattern coordinate data of one stroke and a line connecting a start point and an end point of the one-stroke coordinate data, the sampled pattern coordinate data of the one stroke is converted to straight line and/or curved line segments. The converted segments are quantized and normalized. The segments of the normalized input pattern are rearranged so that the input pattern is drawn in a predetermined sequence. Differences between direction angles for the rearranged segments are calculated. Those differences are compared with differences of the direction angles of the dictionary patterns read from a memory (300) to calculate a difference therebetween. The matching of the input pattern and the dictionary pattern is determined in accordance with the difference, If the matching fails, the first or last inputted segment of the input pattern is deleted or the sampled pattern coodinate data of the next stroke are added, to continue the recognition process.

摘要： Disclosed is a method and an apparatus for recognizing and displaying handwritten characters and figures in which input stroke information on a handwritten input character or figure is read out by an electromagnetic tablet (3), recognition means (7) performs character/figure recognition on the basis of the feature of the input stroke information, display means (2) displays the input stroke information and the result of recognition, and when the result of recognition is displayed on a display screen of the display means, stroke information having been used for recognition is erased from the display screen, and stroke information which is not yet used for recognition, is left on the display screen.
