Abstract
Introduction:Ferdinand Saussure, linguist, semiologist, philosopher and one of the main founders of semiotics, affirms that "Meaning"(significance) is a representation of something created in the mind, an association that is useful for a "Signifier" that is a psychic impression of sound. Objective:In this context, the objective of this research is to verify the feasibility of generating communication based on images formed in the mind (Signified) and what it can represent cognitively related to the Signifier using a brain-computer interface Method:A computer brain interface has been developed and a user has been tested so that it uses neuro-muscular commands and pure mental commands that invoke Signified (records in the user's mind) that represent a goal of communicating. Result:The results allow to evaluate a relationship between signified and signifier of information drawing from thebrain. Psychic images of a communication intent were linked to sound images that are also mental entities, when brain activated, are converted in “speech” (physical sound) computationally. Conclusion:The results demonstrate the feasibility of communication in this modality, which could support the basic communication needs of people who do not communicate orally
