• 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

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

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
