EMOTIV EPOC

What is Emotiv EPOC ? A revolutionary brain computer interface

and scientific contextual EEG offering high resolution 14 EEG channel + 2 references.

HISTORY - Found in 2003 by 4 scientists and

executives: Neuroscientist Professor Allan Snyder, chip-designer Neil Weste, technology entrepreneurs Tan Le and Nam Do.●

Emotive EPOC is a high resolution ,multi channel EEG system having 14 EEG channel and 2 references .

EPOC uses three suites to determine signal inputs:- Emotions (Affectiv suite) – Excitement – Engagement – Frustration

• Facial expression (Expressiv suite)

– eyelid and eyebrow positions, – eye position in the horizontal plane, – smiling, – laughing, – clenching, – smirking

• Cognitiv suite : 13 kinds of movement

– 6 directions(left, right, up, down,forward, and "pull/zoom")

– 6 rotations([anti-]clockwise rotation,turn left and right, and swaybackward and forward)

– visualization ("disappear“).

WORKING - Emotiv Epoc is based on two working

principles which are- Electroencephalography and Brain-Computer Interfacing

Electroencephalography (EEG) is the recording of electrical activity along the scalp produced by firing of neurons within the brain.

A brain-computer interface (BCI), sometimes called a direct neural interface or a brain-machine interface, is a direct communication pathway between a human brain and an external device.

APPLICATIONS -

• Currently this system is being used in Virtual 3D navigation and in gaming applications .

Advantages Potential for EEG

Research Helpful to Handicaps Faster than usual means to

manipulate objects More effective than

traditional ways

AWARDS: Red Dot Design Award Auto Vision Innovation Award Australian International Design Award Australian Engineering Award

Limitations

Many applications are in beta phases Most of the people are yet to be familiarized

It will bring the mind control experience to the whole new level

Future of artificial intelligence, gaming and much more

As detection techniques improve , it will be used by vast number of individuals
