最近有研究順利單憑量度大腦神經的變化，將一名因脊髓受傷而導致手部無法書寫的人士其腦中所想的文字，確確實實地轉化成為實體的螢幕文字，「書寫」速度更高達每分鐘90英文字母!774Please respect copyright.ＰＥＮＡＮＡHIL35R685h

亦即是說，整個過程他只想在腦裡默默想著那英文字母，電腦便會剖釋其腦部的變化，為他打在螢幕上打出文字。774Please respect copyright.ＰＥＮＡＮＡzxlaptrceo

(圖2)電腦首先指令病人在腦海裡思想著利用手部書寫英文字母(如圖中所示)，思索每個英文字母的時候均有間隔，好讓電腦能清楚每一個英文字母所導致的大腦神經變動。774Please respect copyright.ＰＥＮＡＮＡMa7mSDvWd9

經一系列的分析後，科學家將大腦神經的變動組合成3個組件(PC1, PC2, PC3)，而每一個英文字母在3個組件上所導致的變動均是獨特的，圖中所顯示的分別為d、e、m774Please respect copyright.ＰＥＮＡＮＡ3SQcwCNBMD
三個英文字母的神經變動。774Please respect copyright.ＰＥＮＡＮＡ23jnwzae7F

(圖3)若將每一個英文字母甚至標點符號的神經訊息分類，可以得出每個符號均有其獨特的訊號組合。774Please respect copyright.ＰＥＮＡＮＡ1xJ04gNH05

當使用者思索著英文詞語後，電腦分析其神經訊息轉變，再透過電腦程式判斷訊息是為甚麼英文字母，從螢幕中顯示出來。774Please respect copyright.ＰＥＮＡＮＡGklTp1jPQQ
