Abstract

Analysis method for quick component of NIRS is explained. In order to compare quantitatively the amount of quick component, absolute average operation is applied. The result Q is then formulated as the product of magnitude M and density D. By characteristic differences of M and D functional features of each channel are discussed. The method is applied to text entry task to mobile phone. Most of 34 channels under study D values diverged in rest state, but they converged at task state. 6 channels among 34, showed specific responses to specific task.
