This document discusses brain computer interfaces (BCI). It defines a BCI as a direct connection between the human brain and a computer that allows thought-based control of devices. The document outlines different types of BCI acquisition techniques from invasive to non-invasive and describes some applications like assisting disabled individuals and enhancing video games. It also notes advantages like controlling prosthetics but disadvantages like weak signals and complex brains.

2. Introduction
 Brain computer interface is a direct connection between computer an
human brain.
 The brain computer can lead to many applications especially for disabled
person.
 Brain computer interface applications utilize the brain and its newrons
system functions.

3.  A brain computer interface is a technology which allows a human to control a computer
peripheral, or other electronic devices with thought.
 It does so by using electrodes to detect electric signals in the brain which are send to a
computer.
 The computer then translates these electric signals into data which is used to control a
computer or a device linked to a computer.

7. BCI Types
 Invasive brain computer interface acquisiotion techniques
 Partially invasive brain computer interface acquisition techniques
 Non invasive brain computer interface acquisition techniques

8. Invasive BCI Acquisition techniques
 Invasive brain computer interface devices have to be used to capture brain
signales.
 Invasive brain computer interface devices are inserted directly into the
human brain by a critical surgery.
 These devices have the highest quality of human brain signals.

9. Partially invasive BCI Acquisition
techniques
 Partially invasive brain computer interface devices are implanted inside
the shull but rest outside the brain.
 Signal strength using this type of brain computer interface is bit weaker.
 Partially invasive brain computer interfaces have less risk of scar tissue
formation.

10. Non invasive BCI acquisition
techniques
 Non intasive brain computer interface has thes least signal clarity when it
comes to communicating with the brain.
 It has less risk then the above tow method

11. Applications of BCI
 Provide disabled people with communication ,environment control,and
movement restoration.
 Provide enhanced control of devices such as wheelchairs ,vehicles,or
assistance robots for people with disabilities.
 Provide addititional channel of control in computer games.

12. Cont….
 Monitor attention in long-distance drivers or aircraft pilots.
 Develop intelligent relaxation devices.
 Control robots that function in dangerous or inhospitable situations.
 “Google search “ through brain.

13. Advantages of BCI
 Allow paralyzed people to control prosthetic limbs with their mind.
 Transmit visual images to mind of blind person.
 Tranmit auditory data to mind of deaf person.
 Allow gamers to control video games with their mind.

14. Disadvantages of BCI
 The brain is incredibly complex.
 Signal is weak and prone to interence.
 The equipment is less then portable.

15. Conclusion
 Bci is an advancing technology promising paradigm shift in areas like
machine control , reality and etc.
 So ,it’s potentially high impact technology.
