NASA Task Load Index (TLX)

The NASA Task Load Index (TLX) is a tool used to measure how demanding or taxing a task feels to a person. It considers factors like mental effort, physical effort, time pressure, frustration, and the overall difficulty. By assessing these aspects, the TLX helps identify how hard a task is on someone and can guide improvements to reduce workload, increase safety, and enhance performance. Essentially, it provides a structured way to understand and quantify perceived workload during complex activities.
