<p>A symbol displaying apparatus comprises a flat shallow display and means for determining the path of a writing implement 6 on a surface 4 above the display. The display displays the path of the implement 6 directly below the path on the surface 4 so as to resemble writing with a pen or pencil. When a character or symbol has been recognised, its path is replaced by a formalised image. The apparatus may be used to enter text into a word processor and display the entered text. The apparatus may recognise alphanumeric, shorthand or Japanese characters, mathematical symbols, or symbols of circuit components in a circuit diagram. Different colours may be input using a graticule 5 electronically switched to different displayed colours corresponding to the input colours. <IMAGE></p> |
