図1は、本発明の第1実施形態に係る移動体制御装置のシステム構成の一例を示すブロック図である。第1実施形態に係る移動体制御装置10は、ユーザを乗せて移動する移動体(例えば、電動車椅子等)11の駆動を制御するものである。移動体制御装置10は、脳波計1と、教師信号生成部2と、脳信号分離部3と、制御信号生成部4と、駆動制御部5と、VISUAL-FEEDBACK部6と、を備えている。
図5は、本発明の第2実施形態に係る移動体制御装置のシステム構成の一例を示すブロック図である。第2実施形態に係る移動体制御装置20は、第1実施形態に係る移動体制御装置10の構成要素に加えて、更に、筋電位検出部21と、停止判断部22と、を備えている。
図6は、本発明の第3実施形態に係る移動体制御装置のシステム構成の一例を示すブロック図である。第3実施形態に係る移動体制御装置30において、制御信号生成部34は、算出された特徴量fpと、上記特徴量fpと制御信号との対応関係と、に基づいて、特徴量fpに対応する制御信号を連続的に生成する信号生成部34aと、信号生成部34aにより連続的に生成される制御信号を、連続する所定個数(例えば、3個)からなる制御信号のグループに分けて、グループ毎に、各グループの中で最も多い種類の制御信号を選択する信号選択部34bと、を有している。
上述した第2実施形態では、筋電位の検出結果を用いて移動体11の停止制御を行う例を示した。しかしながら、筋電位の利用は、停止制御に限られない。本実施形態では、脳活動情報に基づく移動体11の制御と筋電位に基づく移動体11の制御を統合した具体例について説明する。
上述した第2実施形態では、脳波計によって得られる脳波信号の出力をサンプリングし、各サンプルによって表わされる制御内容に対して時間方向での多数決評定を行う例を示した。本実施の形態では、脳波計が有する複数のセンサ(例えば電極)を3つ以上のセンサグループ(例えば電極グループ)に分け、各センサグループの同時刻の出力によって表わされる制御内容が互いに相違する場合に、多数決評定によって1の制御内容を選択する。
