What is TLX in UX research?
The TLX stands for Task Load Index and is a measure of perceived workload. If you conduct mostly digital UX research for consumers (websites and software), you may not have used the NASA TLX, but as interfaces continue to evolve, you may encounter it soon.
How is the TLX scored?
Two step scoring: Administering the TLX involves two steps. First, a participant reflects on the task they’re being asked to perform (such as a nurse admitting a patient to the emergency room) and looks at each paired combination of the six dimensions to decide which is more related to their personal definition of workload as related to the task.

How are NASA TLX results calculated and analyzed?
NASA TLX results are calculated on the device, and, once a network connection is available, these data are securely uploaded to servers for analysis. This frees researchers from being burdened by the task of tracking individual paper forms or calculating workload scores manually.

What is the response scale (TLX)?
The response scale is essentially a line with 21 marks (see Figure 1). Figure 1: Example of how the TLX is scored on paper (top) and in the mobile app (bottom). To score, you count the number of lines a participant marked, subtract 1, and multiply by 5.

What does TLX stand for?
The Official NASA Task Load Index (TLX) is a subjective workload assessment tool to allow users to perform subjective workload asessments on operator(s) working with various human-machine interface systems. Originally developed as a paper and pencil questionnaire by NASA Ames Research Center’s (ARC) Sandra Hart in the 1980s,…
