| Research Abstract |
We have studied the possibility of understanding ALS patient's requests by any neuro-physiological man-ners. The patient has no physical capability for speaking, though maintaining intellectual activities. In this study, communication with a testee is undertaken in a visual stimulus which is displayed on the ORT screen. For example, Event Related brain Potentials (ERP) appears within his Electroencephalogram (EEG) posterior to the stimulus as the result of intellectual evaluation of proposed visual stimuli. This means that we are well detection, ERP is filtered based on the Haar-Wavelet transform and applied averaging method for some wave-forms. Then, we could obtain a good result for some experiments which chose the word phrase by using these methods. This system will be of much practical use for the communication with ALS patients.
