TL;DR: This system is able to recognize a large class of 2-D mathematic formulas written on a graphic tablet and starts the parsing by localization of the ``principal'' operator in the formula and attempts to partition it into subexpressions which are similarly analyzed by looking for a starting character.
Abstract: Mathematical formulas are good examples of two-dimensional patterns as well as pictures or graphics. The use of syntactic methods is useful for interpreting such complex patterns. In this paper we propose a system for the interpretation of 2-D mathematic formulas based on a syntactic parser. This system is able to recognize a large class of 2-D mathematic formulas written on a graphic tablet. It starts the parsing by localization of the ``principal'' operator in the formula and attempts to partition it into subexpressions which are similarly analyzed by looking for a starting character. The generalized parser used in the system has been developed in our group for continuous speech recognition and picture interpretation.

TL;DR: Handwriting- Recognition and speech-recognition systems, in addition to being useful principal-support workstations (as each is often envisioned), may also form the bases for potentially good text editors for typists and secretaries.
Abstract: Twelve participants were given marked-up manuscripts to edit. Results showed that editing was done much faster (50% and 90%) with a simulated handwriting-recognition system and with a simulated spe...

30 Mar 1984TL;DR: In this paper, the stroke information which is not recognized on a displayed screen and improve man-machine communication by erasing stroke information corresponding to the result of recognition when displaying the results of recognition was discussed.
Abstract: PURPOSE: To leave stroke information which is not recognized on a displayed screen and improve man-machine communication by erasing stroke information corresponding to the result of recognition when displaying the result of recognition. CONSTITUTION: When stroke is inputted with a stylus pen 1 that outputs electromagnetic wave from above a liquid crystal display section 2, the electromagnetic wave arrives at a tablet 3 through a display section 2, and coordinate of input point is read, and sent successively to a handwritten character and graphic recognizing device 7. The device 7 makes handwriting recognition basing on inputted stroke, and in case of coincidence, the result of recognition is sent to a processing device 4. In this case, recognized graphic or character code and recognition information of inputted stroke are sent. The device 4 erases stroke of completion of recognition from a frame memory 5. Change of the memory 5 is displayed in the display section 2, and stroke information which is not recognized is left on the screen. COPYRIGHT: (C)1985,JPO&Japio
