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

Work in Progress

Consulting with Honeywell to resolve Digital Compass Issues

Designing Printed Circuit Board in Eagle for compact design of OSU

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
