      Handicaps
      Handicaps need assistance to perform their everyday activities
    • Problem Statement
      Biometric Security
      High Risk Security
    • Problem Statement
      Medical Diagnose
      For Mental disorders and spinal injuries
    • Objective
      • Help disabled people to normal life and communication without the need of others.
      • Develop a generic EEG Classification that can support different applications
      • Develop brain computer interface application by using cognitive EEG signal.
    • Motivation
      • Help handicaps to normal life and communication without the need of others.
    • EEG signal( Description )
      • Definition:-
      • An electroencephalogram is a measure of the brain's voltage changes as detected from scalp electrodes.
      Electrodes: Small metal discs placed on the scalp in special positions.
    • EEG signal( Description cont)
      • It is an approximation of the cumulative electrical activity of neurons.
      • Actions that affect the EEG signals to three categories:-
      • Muscular Movements
      • Expressive States
      • Cognitive States (Our Scope)
    • EEG signal( Description cont)
      • Study of EEG paves the way for some problem:-
      • Monitoring Alertness, Coma, and Brain death.
      • locating areas of damage following head injury and tumour.
      • Investigating and testing epilepsy.
      • Monitoring the brain development.
      • investigating sleep disorders and mental disorders.
    • EEG signal(Description cont)
      • Waves
    • BrainComputerInterface(Description)
      Definition:-
      Brain Computer Interface (BCI) is a collaboration in which a brain accepts and controls a Mechanical device as a natural part of its representation of the body.
    • Brain Computer Interface( Description cont. )
      What is it good for ?
      • People with little muscle control.
      • Early medical diagnose
      • People with Amyotrophic lateral sclerosis(ALS)
      • Spinal injuries.
      • Mental disorders.
      • Dementia.(cognitive abilities).
      • Epileptic disease.
    • Brain Computer Interface( Description cont. )
      • In Review
      • Allow those with poor muscle control to communicate and control physical devices
