Universal Design Tactile Graphics Production System BPLOT4 for Blind Teachers and Blind Staffs to Produce Tactile Graphics and Ink Print Graphics of High Quality

In order to extend the usability of BPLOT, a new version BPLOT4 was developed. BPLOT is the first tactile graphics production system for the blind that enables the blind to produce tactile graphics by themselves. BPLOT4 has obtained the following four new features: (1) The usage of variables and mathematical formulas is supported for the description of plotter control commands. (2) The production of ink print graphics is possible at the same time as that of tactile graphics. (3) A new GUI (Graphical User Interface) is developed for sighted users. (4) Everest-D V5 (Index Braille) is added to the list of supported Braille printers.
