Brain control Interface (BCI)

Brain control Interface (BCI)

• 1875 - Richard Canton first discovers electrical signals on the surface of animal brains

• 1940s - Wilder Penfield maps the motor cortex for the first time using epilepsy patients

• 1950s - Dr. Jose Delgado invents a device that can be controlled using FM radio waves. Tested on a bull and was able to manipulate him by pressing different buttons

• 1996 - Philip Kennedy implants the first BCI into a human

BCI

• A direct communication link between the human brain and the outside world

• Uses brain activity to command or control the world around by means of a system or device

• Analyzes signals fired from neurons in the brain

REVERSE BCI?

Electroencephalography (EEG)

• Measurements of electrical activity of the brain

• Recorded from electrodes placed on scalp

• Can record and given feedback for any part of the brain

• Can be used for detecting brain diseases

Electroencephalography (EEG)

emotiv

• Wireless = more range on motion

• Better comfort than regular EEG

• Uses thoughts, emotions, facial expression to control

• 14 sensors

• Lithium Battery - 12 hours of continuous use

emotiv

BCI Vs emotivBCI EMOTIV- Time consuming to set up - Conducting gel is needed- Many electrodes are used- Lacking in comfort- Only used in hospital, labs,

etc.- Mainly used for medical

purposes

- No conducting gel required- Cheaper- 14 sensors- Small better comfort- Accessible to everyone- Mainly used for

entertainment purposes

Future• Better technology – combination of EMOTIV and EEG?

• Comfort

• Easy to use

• Cheaper

• Use for military

• Share thoughts between soldiers

• Control exoskeleton (super soldier)

future

• Use for prosthetics

• Brains sends signals to prosthetics
