    • Brain Wave Starter Kit
    • BCI-Brain Computer Interface
    • Applications Using BCI • Produce a two dimensional Electroencephalogram (EEG) controller for widespread application – Mechanical arm – Hands free light for Dentist – Wheel Chair Adapted from www.toysrus.com Adapted from www.fotosearch.com/bthumb http://blogs.static.mentalfloss.com
    • Project Overview http://www.ipmc.cnrs.fr www2.latech.edu Measure Brain Activity (EEG) Translate into signal usable by a device (wheelchair, robotic arm, etc)
    • DATA ACQUISITON
    • ELECTRODE PLACEMENT Letter for region F - Frontal Lobe T - Temporal Lobe C - Center O - Occipital Lobe Number for exact position Odd numbers - left Even numbers - right ELECTRODE PLACEMENT FOR 10-20 SYSTEM [spaced apart 10-20%]
    • BRAIN WAVES Type Frequency Location Use Delta <4 Hz everywhere occur during sleep, coma Theta 4-7 Hz temporal and parietal correlated with emotional stress (frustration & disappointment) Alpha 8-12 Hz occipital and parietal reduce amplitude with sensory stimulation or mental imagery Beta 12-36 Hz parietal and frontal can increase amplitude during intense mental activity Mu 9-11 Hz frontal (motor cortex) diminishes with movement or intention of movement Lambda sharp, jagged occipital correlated with visual attention
    • MINDWAVE MOBILE BRAIN SENSOR EAR CLIP BATTERY TGAM MODULE
    • HEADSET PLACEMENT
    • FEATURES • Single Sensor on FP1 • Can detect multiple mental states simultaneously • Reference electrode on Ear clip to remove ambient noises • IP involves noise cancellation and signal amplification • Provides EMG feature for Eye Blink detection
    • SPECIFICATIONS • Bluetooth ™ Wireless communication • Passive Dry Sensor EEG • Single AAA battery • 10 Hours Run Time eSense Brainwave Patterns: • Attention • Meditation • Eye Blink • Frequency Bands: 0.5 to 50Hz
    • THINKGEAR •TGAM MODULE offers e-Sense technology •Outputs Attention, Meditation and Physical eye blinks from raw EEG data •2.79cm x 1.52cm x 0.25cm, weighs 130mg •Communicates through UART interface at baudrate 1200, 9600 or 57600
    • SUPPORTED PLATFORMS
    • MIND-BOT SPECIFICATIONS: • Micro Controller : 8051 • ZIGBEE MODULE-Frequency : 2.3 Ghz • Attention level < 65 ------ STOP • Attention level > 65 ------ START • Baud rates available at 1200, 9600 ,57600 or 115200
    • Project Overview http://www.ipmc.cnrs.fr www2.latech.edu Measure Brain Activity (EEG) Translate into signal usable by a device (wheelchair, robotic arm, etc)
    • NeuroSky • NeuroSky chip output – DC Motor Control • Pulse width Modulation Fan HighFan MediumFan Off
    • Neurosky • Increase Brain Activity • Increase Pulse Width Fan High http://www.ipmc.cnrs.fr
    • MINDBOT BLUETOOT H UART UART ZIGBEE MODULE SENSES ATTENTION LEVEL BLUETOOTH RFCOMM SERIAL PORT ZIGBEE MODULE 8051 CONTROLLER WHEEL CONTROL BOT uses ‘SERIAL’ function TX COMMAND HEADSET RX COMMAND CONTROLS MOTOR BASED ON COMMAND
    • APPLICATIONS-Continued.. • Portable medical applications • Motor speed control • Drowsy driver detection • Light intensity control • Music play based on mind state • Mind gaming • Sports [ready zone analyser] •
