Electro-optic slate for input/output of hand-entered textual and graphic information

摘要: A portable interactive electro-optic data input/output, storage, processing, and display device responsive to hand printed text drawn graphics. The preferably comprises a combined flat panel pen sensing surface constructed from non-mechanical, non-emissive elements, such as liquid crystal elements. also an input for manual entry of graphics, well commands, directly onto the providing electronic writing drawing slate. elements themselves are utilized sense locations. is so that there no distortion when in contact with surface. Rapid provided accommodating natural movement on high resolution, large area display. character recognition method associated automatic computationally efficient on-line characters, while printing style. Hand characters recognized stored compact standardized format, ASCII, later display, or output external equipment, printer computer. Graphics can be entered device, graphics interspersed text, if desired. Also, information processing equipment and/or processing.
