Nick Gomes BRAIN CONTROL INTERFACE (BCI)

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 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 BCIEMOTIV -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
