Using Environmental Objects as Visual Stimuli in BCI-based Interaction System: Theoretical Approach

摘要

In this study, we consider a novel approach of using subconscious brain activity, presented by evoked potentials (EP), in a BCI-based interaction system. The main idea of the proposed approach is using objects of everyday life as “integrated” stimuli. We investigate different methodologies of operating with visual stimuli in traditional EP-based systems and their applicability of using with environmental objects. The proposed architecture of a novel EP-based interaction system includes a conjunction of BCI and eye tracker (ETI) channels to select and recognize surrounding objects to directly interact with them further.
