Human Research and Engineering Directorate

• Powerful tool for estimating system performance as a function of human performance

• Rendered useless if analyst can not interpret the data

FOCUS: Accentuate the strengths of IMPRINT by redesigning and developing analysis friendly reports

Version 6 ReportsVersion 6 Reports

• Good measures of overall system performance

• Limited look into operator workload

KEY ISSUES

- Plotting Workload Over Time - No report to show operator activity during

points of high workload(especially in VACP/Goal)
