Brain-computer
interface (BCI) is a fast-growing emergent technology, in which researchers aim
to build a direct channel between the human brain and the computer.
These are linguistic independent and can be used anywhere across the world .
Types of BCI:
1.
Invasive
2. Non-Invasive 3. Semi Invasive
Invasive: Invasive
BCIs are implanted directly into the grey matter of the brain during
neurosurgery. As they rest in the grey matter, invasive
devices produce the highest quality signals but are prone to scare tissues.
Non-Invasive:
In this process the user wears a wearable cap which is studded with electrodes.It
has no complication of surgery but signals are weak as they are placed above
the thick skull.
Semi Invasive:
Semi-Invasive BCI devices are implanted inside the skull but rest outside the brain
rather than amidst the grey matter.
Applications:
• Provide
disabled people with communication, movement restoration.
• Provide
enhanced control of devices such as wheel chairs, vehicles, or assistance
robots for people with disabilities.
• Provide
additional channel of control in computer games.
• Monitor
attention in long-distance drivers or aircraft pilots, send out alert and
warning for aircraft pilots.
• Develop
intelligent relaxation devices.
• Control
robots that function in dangerous or inhospitable situations (e.g., underwater or
in extreme heat or cold).
• Bionics/Cybernetics
• Dream
Capture
• “Google
Search” through brain
BCI research is an interdisciplinary endeavour involving neuroscience,engineering,signal processing,rehabilitation and lies at the intersection of emerging technologies such as Machine learning and artificial intelligence among others.
BCI is considered as a new frontier in science and technology.
