| Resumen |
This paper presents an on-going project on the development of a simple cursor control emulating the typical operations of a computer-mouse, using Electrooculography signals (EOG) obtained indir ectly through a commercial 16-electrodes wireless headset originally used to acquired EEG signals. The cursor position is controlled using information from a gyroscope included in the headset. The clicks are generated through the user’s blinking with an adequate detection procedure based on spectral analysis. Empirical Mode Decomposition (EMD) technique is explored as a simple and quick computational tool, yet eff ective, aimed to the pulse detection in a noisy signal, as well as a validation method to distinguish between natural blinking and blinks for control. EMD is compared with a spectral analysis based on the Discrete Wavelet Transform (DWT). The experimental setup, some obtained results, and a comparison among the two used spectral analysis, are presented. |
