Spectral analysis of physiological parameters for consumers' emotion detection

Camilo Valderrama, Gonzalo Ulloa Villegas


This paper show a literature review in the field of emotions detection. Show the strength of aplications of Brain Computer Interfaces (BCI) and what the functionality of it is. Explain how work with neourosignal and how to extract information using Discrete Wavelet Transform to recognize some characteristics that are present in the signal. Also explain the methods which are used for classification the signals. The purpose of the review is established a basis for the development of a project which want define the behavior of brain signal's when a person sees a commercial advertisement.
