書寫文字,無疑必需依靠腦部的幫助才能完成。457Please respect copyright.PENANAeVXcdZnIZe457Please respect copyright.PENANApTBrlPiMl8

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!457Please respect copyright.PENANAViItp2YSax

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。457Please respect copyright.PENANAIGzukuYCEH

(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。457Please respect copyright.PENANASG7cIcQivQ457Please respect copyright.PENANAGBn0Kj09Tk

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、m457Please respect copyright.PENANAfKckvvGkBf
三個英文字母的神經變動。457Please respect copyright.PENANArKsqs8j8xV

(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。457Please respect copyright.PENANABgNhheqToi457Please respect copyright.PENANAWaqcmUvPZi

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。457Please respect copyright.PENANAaaqS88XShe
