Device for generating, detecting, processing and displaying written symbols

摘要

The invention relates to a "device for generating, detecting, processing and displaying written symbols" such as letters, numbers, mathematical symbols, musical notes and other graphical symbols and is preferably constructed as a writing pen which contains a writing system which consists of a writing point with or without emission of a writing substance, a holder for the writing point and/or sensors, and which, controlled by the writing process during the hand-written writing of a symbol, generates particular physical state sequences typical of this symbol, which are converted into suitable signals in a converter and to which a particular symbol from a finite symbol set is allocated in a symbol analyzer. The symbols detected by the symbol analyzer can be processed in a process, and the symbols detected and/or processing results can be temporarily stored and displayed by means of a display and/or tone generator. The device can contain additional devices such as, for example, an electronic clock or a communication unit which, like the processor, can be controlled in their functions via the symbols written down and detected. <IMAGE>
