Brain computer interface (BCI) enables users to control computers and other devices using their own thoughts. BCIs monitor brain activity and translate it into commands for operating the device. They provide feedback to the user, so that they can correct any inputs which caused errors.
The most common method for creating BCIs is the use of electrodes connected to the head or body to record brain signals. These digital signals are examined to identify relevant signal features that best correspond to the user’s needs. These features could include EEG or ECoG response magnitudes and latencies, as well as intensity within specific EEG or ECoG frequency bands or firing rates of individual cortical neurons.
As demonstrated by our survey, the public is enthusiastic about the prospect of applying BCI technology for various purposes. It is evident, however, that BCI researchers should address the numerous issues that have been raised by the public as well as their own experts in order to ensure the advancement of this technology.
Among the major challenges that remain, the most important is the improvement of BCI reliability. A BCI must be as reliable as muscles-based actions. This requires an CNS that is sufficiently plastic to let the BCI to identify and respond to the intended commands. The cost of invasive BCIs is also a major concern. This includes the initial and ongoing implantation, as well in the cost of technical support. If these costs aren’t significantly reduced, the commercial viability of the BCI may still be restricted to the most severely disabled patients.
