This article presented a system of detecting the transformation of oxyhemoglobin(Hbo) and blood flow of inner ear for the research of motion sickness. Based on the different absorption parameters of oxyhemoglobin and deoxyhemoglobin with a near infrared spectroscopy (NIRS) wavelength:660nm and 805nm
a set of engineering formulae were derived for detecting oxyhemoglobin(Hbo) and blood flow from Lambert—Beer Law. The sensor can detect and transform two kinds of transformation human physiology parameters:blood oxygen saturation and blood flow of inner ear. Through transportation data to PC
the system real-time displayed the curves of two parameters and offered forceful theoretic proofs for estimation of vertigo.
