BRAIN CONTROL INTERFACE
(BCI)
Nick Gomes
• 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 EMOTIV
BCI
- 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
EMOTIV
- 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
