  1. To Chong Ryan Offir Matt Ferrante James Kestyn Advisor: Dr.Tilman Wolf Smart Goggles Team Wolf

  2. Augmented Reality Glasses • Virtually superimpose graphics onto real environment • Context-specific information supplied to users real-time

  3. Gaming

  4. Gaming Industry Advancement

  5. 3D View of our system Sensor Board Tunnel Creek Board & Battery

  6. Specifications for Augmented Reality • System Refresh Rate: 20 Hz • Human visual frame rate: 10-12 FPS • Location Accuracy σL: ±2 feet • Average Walking Speed = 4.4 ft/s • Average Running Speed = 22 ft/s • Orientation Accuracy σθ: ±5° • Angle Update Speed: 80 deg/s • Captures “typical” human movement

  7. Block Diagram

  8. Sensing

  9. Sensor Board Design

  10. Prototyping • Arduino + Sparkfun Sensors and GPS

  11. Technical Challenges – Data Accuracy Gyroscope Drift Measured Over Five Minutes Time

  12. Technical Challenges – Data Accuracy

  13. Technical Challenges – Data Accuracy

  14. Measuring Kalman Filter Performance SLOW TURN – 10 degrees per second

  15. Measuring Kalman Filter Performance FAST TURN – 50 degrees per second

  16. Computation

  17. Technical Challenges – Image Alignment BAD GOOD

  18. OpenGL • Draws whole environment • Call simple functions to update camera location • Example: • OpenGL only changes camera position since environment is already computed // rotate 45 in zdir glRotatef(45.0f,0.0f, 0.0f, 1.0f); model->Draw(); glFlush();

  19. OpenGL Camera Camera // rotate 45 in z dir glRotatef(45.0f, 0.0f, 0.0f, 1.0f); Actual View Actual View

  20. Display

  21. Goggle-Based Display http://www.microvision.com

  22. Pico Projector Displays • Image -> Electrical Signals • Electrical Signals drive RGB laser light: intensity & information • RGB + Combiner Optic = single modulated light path • Light output + MEMS Scanning Mirror = Image

  23. Cost Schedule

  24. Timeline

  25. Work in Progress • Developing Kalman Filter • Testing/Debugging Sensor Board • Developing final application

  26. FPR • Final Application: PACMAN • Sensor Board • 3D Filter • Displacement
