Electroencephalogram Control System By Joseph Fletcher Ryan Lacroix Gary Stroup Kenneth Sugerman
Introduction • Electroencephalogram (EGG) to measure brain waves • Detect and use conscious control of electrical signals • Interpret brain waves into a control system Adapted from www.brainstatetech.com
Purpose • Produce a three plus dimensional controller for widespread application • RC car • Mechanical arm • Hands free light for medical uses Adapted from www.toysrus.com Adapted from www.toysrus.com
Consumer Products • One dimensional • Controls a fan that controls the height of a ball • Requires training time • Priced at about $100 • Reversed engineered to see how they work
The Force Trainer The Mindflex • Interprets beta waves • Uses one electrode on the forehead and two references behind the ears • Uses an algorithm to control the fan • Interprets fluctuations in brain waves • Uses two electrodes on the forehead and two references on the ears Adapted from www.thinkgeek.com Adapted from www.mindflexgames.com/
Budget 2 Force Trainer $99 ea Provided by Dr. Park 2 Mind Flex Game $99 ea Provided by Dr. Park 1 Oscilloscope $-- Provided by Dr. Park 1 Multimeter $-- Provided by Dr. Park 1 Pre-amp $-- Provided by Dr. Park 1 Soldering supplies $-- Provided by Dr. Park 1 RC Vehicle $50 25 Electrodes $50 package 1 Electrode prep kit $20 1 Elvis II platform $11000 Provided by Bien Dept 1 Elvis Breadboard $50 1 Lab View software $-- Provided by Bien Dept - Wires, clamps, etc $25 Total $195
Current Work • Research the best location for electrodes • Pre-motor cortex • Frontal Lobe • Keeping symmetry • Discerning a usable signal Adapted from www.nonlinearbiomedphys.com Adapted from educationinjapan.files.wordpress.com
Current Work • Reverse engineering consumer products • Using oscilloscope and breadboard with National Instruments ELVIS software • Identify necessary components Adapted from www.ni.com
