MULTI-CHANNEL EEG ELECTRODE SYSTEM
First Claim
1. A system, comprising:
- a plurality of electrodes operable to sense an EEG signal, arranged in a three-dimensional pattern and each including an indicating unit configured to display information at a position at which the respective said electrode is placed, wherein each electrode of the plurality of electrodes has an identification;
an image sensing device configured to acquire stereoscopic images of the plurality of electrodes;
a control device configured to sequentially cause the indicating unit of each one of the plurality of electrodes to display the information and simultaneously cause the image sensing device to acquire the stereoscopic images of said each one of the plurality of electrodes; and
a processing device configured to calculate position information of said each one of the plurality of electrodes from the stereoscopic images and to allocate the position information to the identification of said each one of the plurality of electrodes.

Abstract
A multi-channel EEG electrode system has a plurality of electrodes operable to sense an EEG signal. The electrodes are arranged in a three-dimensional pattern and each has an identification and includes an indicating unit that displays information at a position at which it is placed. An image sensing device acquires stereoscopic images of the plurality of electrodes. A control device sequentially causes the indicating unit of each electrode to display the information and simultaneously cause the image sensing device to acquire the stereoscopic images of each electrode. A processing device calculates position information of the electrodes from the stereoscopic images and to correlate the position information to the identification of each electrode.
