Single Channel EOG Signal Processing and Features Extraction using Virtual Instrumentation

Patient is aware and awake but body movements are restricted except for eyes, for persons suffering from severe neurological disorders. Bioelectric signals like EEG, EMG, EOG can be used by such patients to communicate with the outside world. The current research paper focuses on EOG signal acquisition using portable Myon biofeedback device and its analysis. EOG signal acquisition was carried with electrodes placed around the eye of 10 different volunteers. Pre-processing is done using cascaded stages of the notch, bandpass filters. After band-limiting the signal, 10 different features are extracted using LabVIEW software.
