4. Hardware/Software Utilization

5. General System Performance
Expectations
quick response to user interactions
efficient subsystems
Example expectations
Augmented Reality - low overhead
Authoring - accuracy
Modeling - efficient algorithm

6. Input/Output Performance
Response time to user interaction
user actions infrequent compared to automated tasks
no problems expected
Possible problems with data transfer rate
limited disk space on PEDD
IETM cannot be fully downloaded
3D card preferred but not necessary

7. Processor Allocation Two most processor intensive operations
wireframe manipulation
speech recognition
Constrained by available PEDD
Pentium 233 MMX processor

8. Memory Allocation Current PEDD constraints 64 meg
No accurate estimates of the memory requirements of each subsystem
Should clarify itself as object design proceeds

9. Hardware Connectivity
