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
6Electrical and Computer Engineering
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.

11Electrical and Computer Engineering
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
Proposed MDR Deliverables
12Electrical and Computer Engineering
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
13Electrical and Computer Engineering
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 can’t be
integrated on the breadboard. Testing will be completed once the gyroscope is mounted onto the PCB
14Electrical and Computer Engineering
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 user’s 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 project’s functionality
Construct rechargeable power supply to meet specs Develop calibration function
17Electrical and Computer Engineering
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 user’s perspective
Future data will be displayed relative to calibration data, increasing accuracy for various user types
