A common framework for input, processing, and output in a rule-based visual language
Joseph J. Pfeiffer, Rick L. Vinyard, B. Margolis · 2002
Isaac is a visual programming language for geometric reasoning intended for controlling mobile robots, currently under development at NMSU. Due to the application area, handling input and output (in particular, sensor input and actuator output) in a manner consistent with the language as a whole is particularly important in this language. The authors discuss the mechanisms employed by Isaac to provide a common framework for input, processing, and output in this language.
