Bio-Interfaces logical and technological systems. In this sense, aspects that are intrinsic to the application of these bio-interfaces will be addressed from a scientific perspective, considering the contributions by Sut- ter (1992), Picard (1998), Chapin et al. (1999), Bayliss & Ballard (2000), Wolpaw et al. (2002), among others, as well as within the scope of cre- ation in arts, design and games, focusing on the productions by Gabriel (Wilson, 2002); Gilchrist, Bradley and Joelson (1997); Zuanon and Lima Jr. (2008 and 2010); Pfurtscheller (Friedman et al., 2007). Reflections will be emphasized based on the design of wearable bio-interfaces, specifically the characteristics essential to their design of in- teraction, taking into account future perspectives for the development of interactive bio-interfaces. sensor (GSR); blood volume pulse sensor (BVPS); breathing sensor (BS); and electromyogram sen- sor (EMG). Galvanic Skin Response Sensor (GSR) The GSR enables the possibility of measuring the parameters of electrical conductance from skin tissue through the application of two electrodes. This conductance is considered a function of the sweat gland activity, which is a part controlled by the sympathetic nervous system. Thus, when an individual suffers from anxiety or is frightened, a quick increase in skin conductance occurs due to the increase in sweat gland activity. This increase actually reflects the changes that are occurring at the stimulation level of the user's sympathetic nervous system as the result of an internal or external stimulus. The GSR then interprets these BIO-INTERFACES BACKGROUND
