Romesh presentation on Artificial Intelligence.

  1. 1. Controlling Computer By Thoughts Episode -1
  2. 2. Why This Topic I chose? The Latest Present Gen.Tech.of S/w-H/w
  3. 3. The Advancements of AI <ul><li>Robotics </li></ul><ul><li>Automation </li></ul><ul><li>Fuzzy Controlled Devices, Instruments and Circuitry </li></ul><ul><li>Smart Home </li></ul>
  4. 4. Fields Which will be Necessary& Contribute in it after 20-30 years <ul><li>Robotics </li></ul><ul><li>Genome Mapping & Genetics Algorithms </li></ul><ul><li>Computer Graphics & Signals System </li></ul><ul><li>Bio-Informatics and Biotechnology </li></ul><ul><li>Medical Science Applications </li></ul><ul><li>Human-Machine Interface </li></ul>
  5. 5. Recent works Done in this field <ul><li>In India, A brain chip invention </li></ul><ul><li>Research team of Newyork dept. of health-Cursor motion by </li></ul><ul><li>Thoughts </li></ul><ul><li>Psychologists of ILLINOIS Univ.-Typing 2-3 chars/ min. by </li></ul><ul><li>Thoughts (Brain Activated Keyboard) </li></ul><ul><li>Research lab of Nippon Telegraph & Telephony System)- </li></ul><ul><li>Direction of Joysticks by Indications </li></ul>
  6. 6. So Be ready in future :--- <ul><li>The 5 senses </li></ul><ul><li>Touch </li></ul><ul><li>Smell </li></ul><ul><li>Hear </li></ul><ul><li>Vision </li></ul><ul><li>Taste </li></ul>If U R Complete Human-Being Nature graced us by
  7. 7. Functioning of Brain
  8. 8. Historical Perspective <ul><li>- In 1970’s DOD-USA started BCI. </li></ul><ul><li>- ARPA –simple comm. System driven by electrical activity </li></ul><ul><li>Recorded from head. </li></ul><ul><li>- Assistance to Fighter-Pilots in II world war. </li></ul>
  9. 9. How it is being possible? <ul><li>Cognitive Engg.- Implanting the Micro-Electrodes in Brain </li></ul><ul><li>known as Neurotrophic-Electrodes. </li></ul><ul><li>EEG- Electro EncephaloGraph- to measure Brain’s Electrical </li></ul><ul><li>Activity </li></ul><ul><li>Skullcap With Electrodes </li></ul><ul><li>Neuronal Chatter-Interface Devices to Link B/w Human & </li></ul><ul><li>Computer </li></ul>
  10. 10. Limitations of EEG (can measure the large scale activity) Challenges in the field (should measure the small scale activity ) <ul><li>Advancement in the Implantation </li></ul><ul><li>Architecture of the Skullcap with Neurotrophic </li></ul><ul><li>Electrodes </li></ul><ul><li>(Hollow Glass-Cone Ball-Point Pen-Tip,Quoted </li></ul><ul><li>with thin gold wire covered with Nerves,Positioned </li></ul><ul><li>at the Cerebral-Cortex just over the Ear) </li></ul>
  11. 11. Sensors(Agent Programs Effectors) Environment Percepts Actions Structure Of AI Program to Handle the Concept
  12. 12. How the Brain is Scanned <ul><li>Using Magnetic-Resource Imaging Computer Graphics </li></ul><ul><li>Patterns of Blood-Flow ,which change according to the </li></ul><ul><li>Thoughts </li></ul><ul><li>Example- U can think about ur Fiance or fiancee, or a killer- </li></ul><ul><li>Villain of movie </li></ul>
  13. 13. The Functioning Of EEG <ul><li>The tip of electrode stimulate the neurons </li></ul><ul><li>Neurons fuse the wire,induction coil fitted on the cap empower </li></ul><ul><li>the electrode </li></ul><ul><li>Signal from motor neuron activity are detected & amplified by </li></ul><ul><li>tiny receiver placed in the electrode under skull </li></ul>
  14. 14. Desired Element : A BIO-FEEDBACK training program Whatever u think, think effectively at the optimum level
  15. 15. Computer Controlled Cursor <ul><li>Recorded Electrical activity controls sound of Buzzer </li></ul><ul><li>Later buzzer is replaced by cursor & man can control the direction of cursor </li></ul>
  16. 16. Brain Activated Keyboards Experimented person see the Rows and columns of matrix for the desired Character and Thinks about that
  17. 17. Challenges <ul><li>Challenge to even understand the simple command of Left and right </li></ul><ul><li>Lack to know the Under Connections of thoughts and voltage levels generated Corresponding To them </li></ul><ul><li>Brain is complex so n no. of activity can be processed at same time & electrode may be confused to choose the correct one </li></ul><ul><li>To get BCI requires full-fledged thourough study of brain & knowing all its functioning </li></ul>
  18. 18. Challenges <ul><li>To get BCI requires thourough study of brain & its full fledged functioning </li></ul><ul><li>Use of brain at the optimum level & concentration power of experimented person </li></ul>
  19. 19. BCI---Brain-Computer Interface <ul><li>Allows person to communicate with or control the external field </li></ul><ul><li>Doesn’t uses the brain’s normal o/p of pathways of peripheral </li></ul><ul><li>Nerves & Muscles </li></ul><ul><li>Expresses the Electrophysiological Signals </li></ul><ul><li>Transform them into control signals as to play video games </li></ul>
  20. 20. Real-Time BCI system Computer system- Adaptive Human computer Interface CPU-Augmentation manager adapts interface behaviour based on events Feedback Control Signals Cognitive events EEG Brain Activity Cognitive Workload Assessment EEG discrete event detection Task context eg. External Event Timing User engaged in cognitive tasks
  21. 21. BCI Interactions User-Maintains a close relation b/w his/her intentions & signal features BCI- translates them into device commands that accomplish the user’s intentions Note-- Generations of Neuro-feedback must run in real time for successful bio-feedback training
  22. 22. 2 Learning Systems Machine- Learns to discriminate the different Patterns of Brain activity as accurately as possible User- He must be able to perform different mental tasks in order to produce distinct Brain signals .
  23. 23. BCI Research Needs <ul><li>High demands on S/w-H/w systems </li></ul><ul><li>Parameter Extraction </li></ul><ul><li>Pattern Recognition & classification </li></ul>
  24. 24. Uses of BCI Research <ul><li>- F or completely paralyzed persons to know their environments & </li></ul><ul><li>Sentiments. </li></ul><ul><li>- Can be used in Aeronautics </li></ul><ul><li>- Boon for disabled </li></ul>
  25. 25. End OF Episode-1
  26. 26. Bibliography <ul><li>IT professional & PC-quest magazines </li></ul><ul><li>Journals of IEEE on Artificial-Intelligence </li></ul><ul><li>Several sites of Fuzzy-Logic & Neural Networks </li></ul>
  27. 27. Any Suggestions &/ Queries ??
