Drawbacks
Limited accuracy
Limited amount of detail
Augmented Reality RAD

3. Scenario An inspector puts on a Stars PEDD
He turns on the PEDD and walks over to a damaged F-18
He stands at the nose cone of the plane
He calibrates the wire-frame
He begins his inspection of the plane
Augmented Reality RAD

4. Proposed System User Interface Manager Calibration User Interface
To manage and display the user interfaces of other subsystems
Calibration User Interface
An interface for calibrating the wire-frame overlay
Device Drivers to Support I/O Devices
Joystick, HMD, Positioning and Orientation Devices
Event System
To interpret low level events and dispatch them to the appropriate subsystems
Augmented Reality RAD

5. Functional Requirements
Manage the HMD
Calibration of the wire-frame display
Interpret low-level data from input devices
Dispatch events to other subsystems
Augmented Reality RAD

6. Hardware Considerations
PEDD must be capable of running a JVM
Java 3D
OpenGL or DirectX required for Java 3D on the Windows 98 platform
Positioning Device
Data must be accurate within three inches for extensibility
Orientation Device
Sensitive enough to track head movement
Augmented Reality RAD

7. Performance Characteristics
Frame Rate
Wire-frame updates must be smooth
Input Devices
Update in real-time to ensure accurate feedback
Augmented Reality RAD

8. Error Handling and Extreme Conditions
Bounds Checking
Make sure information from input devices is valid
Positioning or Orientation Device Failure
Invokes a manual calibration mode
PEDD Failure
No persistent data, requires only a recalibration
Augmented Reality RAD

9. System Interfacing Maintenance Modeling
Request services of the UI Manager
Receive input from our input device handlers
Modeling
Receive input from the input device handlers
Augmented Reality RAD

10. System Modification New Input Devices Require New Events
New Hardware Requires New Device Drivers
Examples: Transparent HMD, more accurate positioning device
User Interfaces
May change with new technology requiring and update in the UI Manager
Calibration
May become fully automated with newer technology
Augmented Reality RAD

11. Security Issues Augmented Reality has no risk of attack
No persistent data
No transmission to external systems
Other Subsystems
Authentication systems
Implemented on systems containing protected data
