  5. Our Project • Orientation Sensing Unit • Gather information from orientation sensors • Data Processing Unit • Process data from the sensors, send information to display • Heads-Up Display • Virtually label surrounding area

  6. Specifications • Label all buildings within a 150 meter radius • Be able to run for 2 hours on the power supply • Be accurate in labeling to +/- 3˚

  7. Specifications • 150 Meters from Knowles

  8. Design Challenges • Sensing (accelerometer, gyroscope, etc.) • System has to respond to user movements in real-time • Noise (i.e.: Compass) • System has to handle electromagnetic disturbances • Size (Embedded Linux) • Portable system that will fit on the users head

  9. Hardware: System Block Diagram

  10. GPS • Determine lat/long position on the campus • Garmin 18 LVC • Features https://buy.garmin.com/shop/shop.do?pID=223#

  11. Digital Compass • Detect what direction the user is looking in • Honeywell, 2 axis digital compass • Features: http://www.sparkfun.com/commerce/images/products/HMC6352-0_i_ma.jpg

  12. Gyroscope • Compass compensation • Gyroscope – Analog Devices ADXRS401 • Features: http://www.robotshop.us/home/suppliers/spark-fun-en/sfe-adxrs401-gyroscope.html

  13. Accelerometer • Detect head movements by the user • ST Micro – LIS302DL, 3 axis Accelerometer • Features: http://www.sparkfun.com/commerce/images/products/08637-04-L.jpg

  14. Microcontroller Unit (MCU) • 40 Pin ATMega32 • µC used for Computer System Lab • Features: • http://www.sparkfun.com/commerce/images/products/ATMega32.jpg

  15. Software • Create a 3D environment with Open GL • Tag points within the environment corresponding to building layout on the UMass Campus • User movements translates to movements in virtual environment • Transpose tags from 3D environment onto HUD

  16. Central Processor Unit (CPU) • Process the signals from the MCU and drive the HUD

  17. Heads Up Display (HUD) • Contacted three companies http://farm1.static.flickr.com/215/489851204_1b60847a1b.jpg?v=0

  18. Power Supply • Orientation Sensing Unit (OSU) is battery powered • Elements in OSU run between 2V-5V • < 100mA peak power across 3.3V and 5V supplies • Data Processing Unit (DPU) is battery powered • ~500mA peak • Voltage regulation • 3.3V National Semiconductor , LP38691DT-3.3 • 5V National Semiconductor , LP38691SD-5.0 • Battery Pack • Ultralife 9V lithium ion rechargable battery, 1700mAh

  19. Associated Costs

  20. Proposed MDR Deliverables • Demonstration of Orientation Sensing Unit • Microcontroller • Accelerometers • Gyroscope • Digital Compass • GPS • Design simple 3D environment with OpenGL • PC based
