7. History of BCI
• Research has been going on for than 20 years.
• Commercially Developed By the Bio-Tech
Company CyberKinetics in 2003 in conjunction
with the department of Neuroscience at Brown
University
10. BCI on HUMANS
• On December 7, 2004, CyberKinetics clinically
tested its Brain-Computer Interface on a human.
• 25 year old with paralysis in all four limbs.
• The implanted brain gate sensor recorded
activity in his motor cortex region while he
imagined.
11. How BCI implements
• Subject must be trained to use the Device.
• With an implant in place, the subject would visualize
closing his or her disabled hand. And with trials the
software recognizes the signal.

13. Technology behind BCI
The technology is comprised of four main
components-
1) Signal Capture System
2) Signal Processing System
3) Pattern Recognition System
4) Device Control System
14. Applications of BCI
• One of the most exciting areas of BCI research is the
development of devices that can be CONTROLLED BY
THOUGHT.
• For a Quadriplegic, something as basic as controlling a
computer cursor via mental commands would represent a
revolutionary improvement in quality of life.
• Ability to control video game by thought, ability to change
TV channels with your mind, etc.
15. Limitations
• Lack Of Sensor Modality
• Very Expensive
• Difficulty in Adaptation and Learning
16. Conclusion
•The Results of BCI are almost Spectacular.
•BCI can help paralyzed people to move by
controlling their own electric wheelchairs, to
communicate by using emails, etc.
•Conclusively, BCI has proved to be a boon for
paralyzed patents.
