  1. Motion Tracking HMD Nick Sorenson Adam Thompson

  2. Milestones Accelerometers • Mount to Visor • Measure outputs that match what we’d expect

  3. Milestones Microcontroller • Take in and perform computations on input signals • Apply signals to Microcontroller and get the appropriate outputs • Calibrate Microcontroller output limits with buttons

  4. Soft Ware • Microcontroller • Device Driver

  5. Range of MotionBaseline

  6. Range of MotionBaseline++

  7. Range of MotionAdvanced

  8. Milestones Tripod/Servos • Bust mounted to tripod • Servos attached to tripod • Move the tripod by applying various inputs

  9. Milestones Integration • Attach Servos to Microcontroller output • Move servos by applying various signals to Microcontroller • Attach Accelerometer to Microcontroller and measure appropriate outputs • Connect Microcontroller to Computer • Additional Wow steps • Test : Test : Test!

  10. WOW • Real Device Driver • Wireless • Pitch and Yaw • Re-Centering • Extra Function Buttons • Range of Motion

  11. BOM LCD Glasses-INNOVATEK V-490 Accelerometer-ADXL330 Microcontroller-M68HC11x2 Servos-36G Servo DAC and Misc. Circuitry Power Supply

  12. Accelerometer Data Sheet

  13. Reality Check Dates • 31 July; Parts are in, DAC understood and ready; tripod built • 30 Sept; Parts mounted, hardware check of accelerometers, and microcontroller. • 31 Oct; Final microcontroller program (either to emulate or to act as separate device) • End of Class; 
