2A2-C05 Estimation of the Head Motion Component of the functional Near-Infrared Spectroscopy (fNIRS) Data(Sense, Motion and Measurement(2))

Abstract

To evaluate KEIROKA technology by the brain activity, investigation of cerebral blood flow due to brain activity is conducted by using functional near-infrared spectroscopy (fNIRS). However, it is difficult to measure the brain activity using fNIRS during exercise because cerebral blood flow changes due to head motion not to neural activity. The head motion component is an obstacle to measure the brain activity. This research tried to estimate the head motion component by using 3D Motion Capture. And the head motion component was estimated by the pitch angle. The author also tried to subtract the head motion component from fNIRS data during exercise. The way to remove will be shown.
