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