Abstract

Disclosed herein is a system for operating chirographic devices. The system may support a spatial chirographic sign reader, a spatial character recognition technique, a chirographic text character writer, a chirographic text character setter, a chirographic text character scanner, a spatial chirographic sign rendering technique, and a spatial chirographic styling sign marker. The system may include a central system unit having a real-time timer clock and bus connectors for chirographic input and output devices. Input device drivers may be adapted to collect spatial chirographic data and label samples with real-time data acquisition. Data may be transferred to chirographic applications of the system for character recognition, text setting, handwriting page scanning, sign styling, and image rendering to achieve specific chirographic effects.
