ABSTRACT:

In this disclosure a man means any human being regardless of sex or age. Present invention belongs to data input devices which are a subdivision of interface devices which are means for two-way flow of information in a man to a machine communication. The data input devices deliver the information from a man to a machine, whereas the data output devices deliver the information from a machine to a man.
Alphanumeric data consist of following data characters: alphabethical characters (letters), numeric characters (numerals), special symbols (like star *, pound # and other similar symbols for performing of some specific function) and one or several space marks, specifically assigned for separating of other symbols. There are many known configurations of input devices: control panels, push buttons pads, keyboards, etc. The problem with them is that they contain big number of switches, assigned to various functions, which often are confusing and different for various machines in same environment and difficult for a man to remember. To some extent this problem is addressed by input devices with alphanumeric characters, hand written by a man and recognizable by a machine. Application of these devices is limited because they need means to run a computer program for characters recognition.
A purpose of present invention is to propose a method and device for input of alphanumeric data into a machine by a man in a manner of hand writing with no need for softwear-based means for alphabetical characters recognition. This is achieved according to present invention by defining each character as a specific collection of signals which are produced by actuation of group of sensors by a hand held stylus, moved by a man in a hand-writing manner along predetermined traceable paths and which (signals) are recognizable by electrical hardware circuitries without any computer softwear.
