In this paper, we tried to suggest feature extraction method using CSP Algorithm to improve the accuracy of classifier according to finger movement to develop the Upper Limb Rehabilitation Robot System based on brain signal. Four subjects participated in the experiment and they conducted four kind of tasks in three times. The task is divided by two kind of movement(Digit Flexion/Extension, Thumb Flexion/Extension),...
Functional near-infrared spectroscopy (fNIRS) has become an established tool to investigate brain function and it is an interesting modality for brain computer interfaces (BCIs). This paper was aimed at examining whether fNIRS can be an appropriate BCIs modality. Brain activities of three subjects performing a right-hand finger movement (flex and extend the fingers and thumb) tasks were measured by...
A functional near-infrared spectroscopy (fNIRS) which is a non-invasive modality to measure hemodynamics of cortices-is today the frequently reported optical brain imaging method for rehabilitation. Neuroimaging studies such as with functional magnetic resonance imaging (fMRI) or positron emission tomography (PET) have been very confined due to a motion limitation of subject at their measuring facilities...
Recently, a functional near-infrared spectroscopy (fNIRS) is frequently reported optical brain imaging method from the standpoint of clinical feasibility. This paper was aimed at examining whether fNIRS can be an appropriate brain imaging modality for checking the progress of rehabilitation treatments or not. Two healthy adults performed the given task. Stand to sit task was offered in this study...
Passive movement, action observation and motor imagery as well as motor execution have been suggested to facilitate the motor function of human brain. The purpose of this study is to investigate the cortical activation patterns of these four modes using a functional near-infrared spectroscopy (fNIRS) system. Seven healthy volunteers underwent optical brain imaging by fNIRS. Passive movements were...
This study showed an example of neurohaptic interface which can be the direct connector between haptics and brain. We investigated the neural activities of motion which are essential tasks for haptic interaction. Eating was adopted to explore the neural activities from the functional near-infrared spectroscopy (fNIRS) imaging. Subjects carried out real motion, action observation, and motor imagery...
