This document discusses brain-computer interfaces (BCI). A BCI allows direct communication between the brain and external devices, establishing a link for control. The structure of a BCI includes hardware components like a chip connector and converter to process brain signals, typically electroencephalography (EEG) readings. Experiments have successfully used BCIs on rats and monkeys to control devices via thought. Potential applications include assisting paralyzed patients, military/civilian research, gaming control, and a bionic eye. While BCIs offer advantages like direct brain communication and technological advancement, they also face challenges such as training requirements, costs, and potential security issues. Overall, BCIs represent an advancing paradigm that could enable new capabilities in machine control,

10. HOW BCI WORKS ?

12. IMPLEMENTATION ON RAT AND MONKEY
SUCCEEDED!!!!

13. SO NOW ON
HUMAN...
It’s a
revolution!!!

14. APPLICATIONS :
• MENTAL TYPEWRITER
• BCI offers paralyzed patients improved quality of life.
• MILITARY and CIVIL RESEARCH.
• Allow patients to control a computer by conscious
changes of brain activity

15. GAMING CONTROL

16. Eye Can Say a lot….

17. BIONIC EYE
An artificial eye can see a lot…

18. May be in future !!!
Human dive into a virtual
world by connecting their
brains directly to a
computer
Harder concentration to
the fan to blow for
simulating the ball to float

19. ADVANTAGES
• DIRECT COMMUNICATION between
human brain and computers.
• Better LIVING, more FEATURES, more
ADVANCEMENT in technologies etc.
• New work area for scientists and
researches around the world.
• LOW BANDWIDTH.

20. DRAWBACKS:
• Virus attacks may occur to brain
causing ill effects.
• Requires extensive training.
• BCI techniques are costly.
• Low speed.

21. CONCLUSION
• A potential therapeutic tool.
• BCI is an advancing technology promising paradigm shift in
areas like Machine Control, Human Enhancement, Virtual
reality and etc. So, it’s potentially high impact technology.
• Will enable us to achieve singularity very soon.
• Intense R&D in future to attain intuitive efficiency.
