NASA-TLX

We're currently re-designing our online version of the NASA-TLX, a subjective, multidimensional workload assessment tool. Our version has been used by thousands of researchers to measure perceived workload. We originally developed it back in 2006 and it's time for an upgrade!

The NASA-TLX rates perceived workload on six different scales: Mental Demand, Physical Demand, Temporal Demand, Performance, Effort, and Frustration. It was originally developed by the Human Performance Group at NASA Ames Research Center over three years and more than 40 laboratory simulations, and is thought to be one of the most validated workload measurement tools in Human Factors Psychology and Engineering.
