Personal Heads-Up Display

Preliminary Design Review

our project
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
specifications
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˚
specifications7
Specifications
  • 150 Meters from Knowles
design challenges
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
