HU Hanbin1,ZHU Ye2,JIANG Tianzi2(1.Department of Automation,University of Science and Technology of China,Hefei 230026,China;2.China Science of Academic,Institution of Automation,Beijing 100190,China)  
In the article,Near-infrared spectroscopy is used on Brain-computer interface′s development.By recording brain signals during tasks such as finger-tapping、imaging finger-tapping and calling by name,calculating the Hurst index,then using Hurst index as input of a Back-propagation neural network,a model of task and brain response was constructed.The results show that the accurate rate is over 70%,it is possible to used NIRS on BCI.
