Research Abstract

As a basis to develop a human interface for communication aids for the handicapped, we conducted a study on the behavior of P300 components for selecting one of the words presented through a speaker in a random sequence. For the auditory stimulus of the word-selecting experiments, 5 words were used. The target word was randomly applied with a probability of 20 %. The subject was instructed to keep a mental count of the number of target words. The P300 components were obtained from the target responses by means of the following methods : 1) Band-pass filtering of the central frequency of 3 Hz, 2) Averaging the single-trial responses to each stimulus 30 times, 3) Subtracting the common components in ERP responses for both target stimuli and non-target stimuli, and 4) Cutting out the P300 using the time-window of the trapezoidal form. Results show that the P300 component can be used to detect the attention of the subject without any physical action. However, right words were selected in a percentage of about 60 %. More experiments will be needed for future work to improve the percentage.
