Data annotation, input and output system - using paper recording medium having column and line inputs with nodes and node markings

摘要

The data annotation, data input and data output system, uses only one paper recording medium to communicate between computers and computers, humans and humans and computers and humans. The system consists of column and line inputs, nodes of column and line inputs, meanings of nodes and markings of nodes. The column and line inputs and markings are produced by a number of standard symbols available on a computer printer. The nodes are produced by standard letters. There is an optical reading system where the meanings of marked or unmarked nodes is determined by the pattern of active reading units and the position of the nodes concerned in the pattern.
