In recent reviews of complex-dynamic system, 88% of those were resulted from the incomplete situation awareness. Ensuring the improvement of situation awareness is a important issue in the interface design and V&V stages. The measurements of situation awareness include physiological measurements, performance measurements, subjective techniques, and questionnaires. SAGAT (situation awareness global assessment technique) developed by Endsly had been used extensively. But SAGAT lack a quantification procedure and can''t be used to measure the distribution of SA. The situation awareness measurement in this study extends from SAGAT ''s freeze technique and interrupting, subjective observer-rating to a quantitative method. Considering the task property of operators in control room, we can measure the degree and distribution of SA. After experiment verifying by two interface, result show that: level 1 SA, level 2 SA, and prior-, rear-task SA show significant difference, and the result considers performance. By observing, the main factors affect SA are grouping representing, and sorting. Results show that the situation awareness measurement has enough validity and sensibility.
