An implementation of the NASA Task Load Index (NASA-TLX) including subjective feedback on conditions and demographic survey.
From the respective Wikipedia article:
The NASA Task Load Index (NASA-TLX) is a subjective, multidimensional assessment tool that rates perceived workload, in order to assess a task, system, or team’s effectiveness or other aspects of performance. It was developed by the Human Performance Group at NASA’s Ames Research Center over a three year development cycle that included more than 40 laboratory simulations. It has been cited in over 550 studies and a recent search for “NASA-TLX” on Google Scholar revealed over 3,660 articles. These statistics highlight the large influence the NASA-TLX has had in Human Factors research.
Learn more about it at the official NASA-TLX website. You can also take a look at the original paper Development of NASA-TLX (Task Load Index): Results of Empirical and Theoretical Research (PDF format, 1.4 MB).
