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
• Power Supply
• Use rechargeable batteries
• Allow user 3 hours of continuous use

6
Specifications

• Able to label building /- 3º off center from a
  min distance of 150m
• Be able to measure pitch and roll accurately
  within /-2º.
• OSU must be head mountable.
• Batteries must be able to power OSU for 3 hours
  continuous use.
• System must have means of calibration/reset.

7
Specifications

• 150 Meters from Knowles

Proposed MDR Deliverables

• Demonstration of Orientation Sensing Unit
• Microcontroller, Accelerometers, Gyroscope,
  Digital Compass, GPS integrated on a breadboard
• Display position and orientation of the OSU on a
  Windows based PC using HyperTerminal
• Design simple 3D environment with OpenGL
• Control movements of simple 3D object (Open GL)
  on a Windows based PC

12
MDR Achievements

• Created 3D object in OpenGL on Windows PC
• Integrated Accelerometer on breadboard with MCU,
  displayed data on PC via HyperTerminal
• Implemented GPS parser on MCU, positional data
  available on PC via HyperTerminal
• Integrated Digital Compass on breadboard,
  displayed data on PC via HyperTerminal
• Inconsistent data retrieved from Digital Compass.
  
• Most likely due to faulty device.
• Contacted Honeywell to find solution

13
MDR Achievements contd.

• Connected 3D object to accelerometer
• Object responds according to accelerometer data
• Developed algorithm to retrieve data from
  gyroscope
• Gyroscope is a surface mount part, which cant be
  integrated on the breadboard. Testing will be
  completed once the gyroscope is mounted onto the
  PCB

14
Work in Progress

• Consulting with Honeywell to resolve Digital
  Compass Issues
• Designing Printed Circuit Board in Eagle for
  compact design of OSU
• Professor Wolf is in contact with BAE for a
  sample HUD

Future Goals

• Obtain Heads Up Display
• Develop algorithm to calculate users field of
  view based on data from sensors
• Algorithm must also find what building are in the
  field of view and display appropriate information
  on the HUD
• Obtain data about several buildings on campus to
  demonstrate projects functionality
• Construct rechargeable power supply to meet specs
• Develop calibration function

17
Calibration Feature

• Each user has unique facial configuration and
  unique viewing mode through glasses
• Project must deliver information to user
  consistently indifferent of point of view
• A calibration feature will provide a fixed point
  of reference based on the users perspective
• Future data will be displayed relative to
  calibration data, increasing accuracy for various
  user types
