Σύνοψη	The NASA Task Load Index (NASA-TLX) is a multidimensional subjective workload assessment tool developed by Sandra Hart and Lowell Staveland at NASA's Ames Research Center in 1988. It measures six dimensions of cognitive and physical task load to quantify operator workload across diverse task domains, from aviation and process control to human-computer interaction. The TLX has become the gold standard for workload measurement in human factors research and applied settings.	The Situational Awareness Rating Technique (SART), developed by Robert Taylor in 1990 for the NATO Advisory Group for Aerospace Research and Development (AGARD), is a subjective post-task measurement instrument for assessing an operator's degree of situational awareness (SA)—the perception of elements in the environment, understanding of their meaning, and projection of their future state. SART is widely used in aviation, military operations, emergency response, and human-factors research to evaluate system designs, training effectiveness, and task demands that enable or impair operator situational awareness.
