The research projects carried out at the RCS over recent years include: 

• a comparative analysis of language-specific pretheoretical sign conceptions (Greek, Italian, French, German, English, and Chinese)
• a systematization of sign concepts for describing the evolution of communication 
• an experimental investigation into the temporal and structural aspects of the production of narratives in various channels, media, and codes (simultaneous narration and renarration of a language-free color tone film) 
• an experimental investigation into guided acquisition of reading proficiency in foreign languages (including Serbo-Croatian, Persian, Chinese)
• a comparative semiotic analysis of youth culture in Berlin and Warsaw 
• a historical account of changes in the concepts of emotion in Indoeuropean cultures (based on evidence from language, institutionalized norms, and philosophical literature)
• a theory of texts (their genres, functions, and structures in all media and channels, i.e. including literature, music, and the arts)
• an analysis of the context-dependence of perception and cognition (jointly carried out by semioticians, linguists, psychologists and information scientists)
• a lexicon of Central European gestures (emblems), combined with a system for automatic gesture recognition and production through a data glove 
• a comparison of the hand movements involved in: 1. handling artifacts, 2. simulating (1), 3. teaching (1) and (2), and 4. illustrating verbal utterances about (1), (2) and (3) 
• the design of a system for rendering audible the structures of pieces of music by means of computer software (collaboration of semioticians with mathematicians, information scientists and musicologists) 
• the semiotic analysis of driver models used for the simulation of vehicle behavior in traffic engineering 
• a computational analysis of the sign structures of classical European music with the aim of creating visual and auditory user-interfaces for operating with these structures in music description and performance.
