| Outline of Final Research Achievements |
We have developed a user-interface for a mobile robotic arm in this study. We made a visual stimulus program that one of four triangles was randomly turned white in a computer monitor. Six able-bodied volunteers participated in the experiments. EEG signals were recorded from the scalp, amplified, sampled, and bandpass-filtered. Each subject was required to silently count white triangle. Some features, event-related potentials P300 and N100, were extracted from the averaged waveforms, and the total of classification accuracy across subjects of 95.8 % was obtained using artificial neural network.
A vision-based user interface was also considered. The user interface consists of a single web camera to obtain user’s eye movements, computer running a detection program of the center of the iris and pupil from the captured images. An able-bodied subject could operate the proposed user interface without any difficulty. The interface allows user to support to select one of foods on a table.
