This book explores the challenges of developing a digital computer input device capable of reading and understanding handwritten FORTRAN programs. It begins with the development of a 2000-specimen library of handprinted characters, and progresses through various experimental techniques for recognition. The author, with experience in adaptive systems, sought to determine not only how to recognize patterns—specifically handprinted symbols—but also to develop more general methods of pattern recognition that could be used in other applications. The development of a flying spot scanner to convert specimens to digital form, and the subsequent creation of a binary library tape for use with the IBM 7090, are also detailed. The reader will gain valuable insights into the nature of pattern recognition, the complexities of creating character-recognition systems, and the development of methods that may be applied to other fields of study and technological development.
