本研究では，一定周期で点滅する視覚刺激により生じる脳波を用いて，注視するだけでメニュー選択などを行う視覚刺激型ブレイン・コンピュータ・インタフェース（視覚刺激型 BCI）の高度化を目的として研究を行っている．特に本研究課題では，ヒトの視神経に関する特徴である視交叉（視神経交叉）と，VR ヘッドセットを用いた左右眼独立刺激を用いた新しい視覚刺激型 BCI について検討を行っている．
<BR>
令和元年度は目的とする「ヒトの視交叉を利用した視覚刺激型ブレイン・コンピュータ・インタフェースの構築」の基礎となる知見を得るため，視交叉の特性を意識した右視野・左視野に対する視覚刺激と視覚野付近の脳波に発現する定常状態視覚誘発電位 (state-steady visual evoked potential: SSVEP) の発現部位・発現特性の調査を行った．具体的には，注視点を中央として左右に 5 箇所ずつ刺激位置を変化させた計 11 箇所に対して一定周期の視覚刺激を行い，このときに発現する脳波の SSVEP を後頭部の視覚野周辺の 7 箇所で測定し，刺激位置により強度分布がどのように変化するか調査を行った．この実験では視交叉の特性に基づき，左視野側を刺激した際には右脳側の，右視野側を刺激した際には左脳側の SSVEP 強度が増加する，という反応を予想していた．しかしながら，実際に実験協力者 8 名を対象に確認実験を行ったところ，刺激位置を注視点からずらすことで SSVEP の共同が左右で変化することが確認できたものの，実験協力者 8 名中 6 名で予想とは逆の反応が現れることを確認した．

The tongue movement plays an important role in eating and swallowing. In this study, we constructed a system to assist swallowing rehabilitation to show the own motion of the tongue using a cursor on display. We measured the potentials on the gum from the electrodes installed on the mouthpiece. The signals were translated to the frequency domain using Fourier transform and split into specific bands for calculating the feature signals. We used the feature signals to estimate the motion of the tongue. This method is less uncomfortable and can use for long-term stable measurement, unlike conventional methods. Additionally, we developed a novel robotic device for vertical tongue movement. This device evaluates the agility of the tongue under a load, which may lead to a new evaluation index of tongue movement.

This study aimed to develop and demonstrate the feasibility of a BMI-assisted rehabilitation system for spinal cord injury (SCI) patients. The system detects the patient’s desire to move his or her paralyzed legs without delay on the basis of his or her brain activity and make his or her feet that are fixed to the pedals of the system rotate by using a motor and/or functional electrical stimulation. An experiment was conducted in which both healthy subjects and a SCI patient used the system. The system detected the motor intention from the ERD of the alpha and beta bands of the subjects’ EEG without delay. Although the S/N ratio was not high when dry electrodes were used, and the rehabilitation effect of the system needs further study, the discrimination for the SCI patient between his imagining pedaling and keeping a static state showed comparable accuracy compared to that of the healthy subjects (depending on the case but around 70%), demonstrating good feasibility of the system.

本年度は，アクティブ―ドライ電極の利用による脳波計測環境の簡素化および半教師付き学習による識別器の自動更新手法の確立に取り組んだ．
まず，ペーストなしでの脳波計測を行うことを目的とし，アクティブ計測が可能な小型で無線式の脳波計(Polymate Mini AP108, ミユキ技研)を利用した．この脳波計は，皮膚と電極間の接触インピーダンスの影響を受けにくいアクティブ電極であり，導電性ペーストが不要，充電池による駆動とBluetoothによる脳波信号の無線伝送が可能である．しかし，そのままでは足の運動に関するとされる頭頂部付近にうまく電極を固定することができなかった．そこで，頭頂部付近の脳波を安定して計測するための電極固定具の開発を行った．この結果を含め，製作したリハビリテーションシステムについて日本人間工学会システム大会にて発表し，奨励賞を受賞した．
次に，これまでに提案してきた識別器を自動更新型にするための手法について検討した．まず，脳波に比べて得られる信号特性の変化を捉えやすい筋電位を対象とすることとし，微小に計測位置を変化させた場合に得られる筋電位の変化を求めた．次に，筋電位の特性変化に対して動作識別器を自動的に更新する手法として，半教師付き学習を用いるものを新たに提案した．この手法では，測定された筋電位がどの動作パターンに属するのかを，測定された信号が持つデータの分布に関する情報も用いることで，より正確に分類しようとするものである．得られた分類結果をもとに識別器の再学習を自動的に行うことで，筋電位の特性が変化した場合でも利用者に負担を与えることなく性能を維持することができる可能性を示した．この成果は脳波からの動作企図分類問題にも適用できると考えている．この結果をもとに，筋電位からの動作分類時の識別器更新手法としてまとめ，計測自動制御学会論文集で発表した． -
Development of a Robot Prosthetic Hand System Based on Finger Joint Angle Estimation Using Surface EMG Signals

The goal of this study was to develop a robot prosthetic hand system for an amputee that estimates his desired finger angle from surface EMG signals, and operates with the motion he intends. Consequently, we have proposed a finger joint angle estimation method based on a histogram of EMG signals and a linear model. Moreover, a 2-DOF artificial finger robot has been designed and developed. Using this robot and our proposed finger joint angle estimation method, we executed a robot prosthetic finger system demonstration experiment. As a result, it was confirmed that our system is technically feasible for application to a real prosthetic hand system.
