On the suitability of near-infrared (NIR) systems for next-generation brain?computer interfaces

摘要: A brain–computer interface (BCI) gives those suffering from neuromuscular impairments a means to interact and communicate with their surrounding environment. BCI translates physiological signals, typically electrical, detected the brain control an output device. significant problem current BCIs is lengthy training periods involved for proficient usage, which can often lead frustration anxiety on part of user. Ultimately this abandonment The primary reason that relatively indirect measures cognitive function, as be gleaned electroencephalogram (EEG), are harnessed. more suitable usable would need measure function directly. In order do this, new measurement modalities, signal acquisition processing, translation algorithms addressed. paper, we propose novel approach, using non-invasive near-infrared imaging technology develop user-friendly optical BCI. As alternative traditional EEGbased devices, have used practical techniques detect characteristic haemodynamic responses due motor imagery consequently created accessible simple attach requires little user training.
