  1. Remote Control of a Television Set via Thought Patterns Dr. William Hunt, Project Advisor Josh Rosner Drew Petry Gary Grimm George Melcer Thursday, March 11, 2010

  2. The MindLink System • Manipulates television functions via user thought patterns • Provides independence to handicapped and disabled persons • Estimated development cost at $80,940; per unit cost will be approximately $500

  3. Design Objectives • Minimize system costs to maximize target market • Offer intuitive interface for non-technical users • Manipulate simple command set for IR (Infrared) controlled devices • Detect EEG (Electroencephalogram) signals in real-time to provide reliable thought pattern analysis • Utilize Emotiv API (Application Programming Interface) in analysis software • Interface with modified off-the-shelf remote control

  4. Current Status • EEG Headset • Selected and purchased headset • Commenced training with one engineer • Host PC / EAS • Designed Pseudo code and learned about API • SPB /URC • Completed Circuit Design and Board Layout

  5. EEG Headset

  6. Illustration

  7. Input Propagation

  8. Emotiv Control Panel

  9. Cognitive Suite

  10. Expressive Suite

  11. EEG Headset - Problems / Issues • Problem: Consistency of EEG signal from user • Proposed Solutions • More training • Alter sensitivity settings • Use Expressive Suite • Problem: Placement of headset • Proposed Solutions • Need consistent signals to test • Seek advice from Emotiv online community

  12. Host PC:EmoState Analysis Software

  13. Software Process

  14. Software Logic

  15. EAS – Problems / Issues • Problem: Invoking and communicating with Emotiv API • Proposed Solutions • Should include EDK.h and link with EDK.dll • Use EE_EngineConnect for communication with headset; EE_EngineRemoteConnect used for communication with EmoComposer (debugging) • Problem: Sending commands to Synergy board • Proposed Solutions • Propose communication of serial connection • Invoke .NET System.IO.Ports namespace and use instance of SerialPort class

  16. Synergy Prototyping Board & Universal Remote Control

  17. Synergy Prototyping Board

  18. SPB Layout

  19. Synergy Prototyping Board Firmware

  20. SPB – Problems / Issues • Problem: MOSFETs did not interface with URC as expected • Proposed Solution • Opted for bi-lateral switches instead of MOSFETs because we are open/closing a circuit, NOT pulling the signal high or low • Problem: Simulation of SPB requires too much time • Proposed Solution • Use “trial and error” approach with physical implementation of the board • Problem: Soldering joints are weak on URC • Proposed Solution • Use RTV silicone to isolate joints and prevent breaks

  21. Acceptance Testing • EPOC Headset • Train and test with Emotiv Control Panel • EmoState Analysis Software • Utilize EmoComposer, printf stream, and debug symbols • Synergy Prototyping Board & Universal RC • Component Testing (Switches, Microcontroller, etc.) • Board Testing (LED Blink Program) • MindLink System • Iterate through defined thought patterns

  22. Projected Schedule • March 19th • EAS Development Complete • SPB Firmware Development Complete • April • 16th: System Integration Complete • 30th: Final Project Summary Complete • May 6th • Final Report Complete • Successful Project Demonstration

  23. Budget & Cost AnalysisMindLink Venture • Prototype • Initial Capital Expenditure: $750 • Labor Costs: $80,000 • Per Unit Component Cost: $500 • 10,000 Units Production over 60 Months • Total Costs: $3,700,000 • Total Sales ($500 per unit): $5,000,000 • Net Profits: $1,300,000

  24. Future Work • Headset • Complete Emotiv Control Panel Training • EmoState Analysis Software • Port pseudo code to C# • Develop and test serial port interface class • Test and debug • Synergy Prototyping Board • Order PCB and generate Gerber Files • Order Additional Components • Develop Firmware • Test and debug • MindLink System • Complete component integration • Test and debug

  25. Questions / Feedback • EmoState Analysis Software • How to interface C# with serial ports? • Synergy Prototyping Board • Alternative Solutions?
