Interactive diagrams for Charles Peirce's classifications of signs
Priscila Farias

This article presents some results of an ongoing program of research on new strategies for the visualization of sign processes and structures --something I am proposing to call 'sign design'. The current focus of this research are the various (3-, 10-, 28- and 66-fold) classifications of signs described by Peirce. The main issue addressed here is how computer graphics and design methodology may help us to build dynamic and interactive models that serve as tools for the investigation of sign theory. Two models are presented. One of them concerns specifically the 10-fold classification, while the other deals with the deep structure of Peirce's various trichotomic classifications. The first is '10cubes', an interactive 3-D model of Peirce's 10-fold classification. The second is '3N3,' a computer program that builds equivalent diagrams for any n-trichotomic classification of signs, allowing us to analyze and compare different hypothesis regarding those classifications.
