One means of improving the results obtained by (Barea, 2001) is
to use a CWT to process the EOG signal acquired. The CWT is useful
for detecting, characterizing and classifying signals with singular
spectral characteristics, transitory content and other properties related
to a lack of stationarity (Brechet, Lucas, Doncarli, & Farina,
2007). In the case addressed here, the best results are obtained
by using the db1 mother wavelet from the Daubechies family
