Brain-Computer Interfaces (BCIs) enable direct communication between the brain and external devices, utilizing either invasive methods with implanted electrodes or non-invasive methods with external scanning devices. Key components include signal recording, processing, and feedback, with applications ranging from gaming to future potential in virtual reality. However, BCIs face challenges such as the brain's complexity, weak signals, and portability issues.

3. What is it?
--- A collaboration
in which a brain
accepts and controls
a mechanical
device

4. BCI Types
Invasive BCI:
implant electrodes directly onto a patient’s
brain.
Non-Invasive:
implant medical scanning devices to read
brain signals.

Humans dive into a virtual Harder concentration to
world by connecting their the fan to blow for
brains directly to a simulating the ball to float
compute

11. BCI DRAWBACKS
THE DRAWBACKS OF BCI :
- THE BRAIN IS INCREDIBLY COMPLEX,
- THE SIGNAL IS WEAK & PRONE TO INTERFENCE,
- THE EQUIPMENTS IS LESS THAN PORTABLE,
