NASA-TLX in HTML and JavaScript

Home > Software > NASA-TLX in HTML and JavaScript

The NASA task load index (TLX) is a procedure for assessing subjective task workload. It is a time-honored procedure used in HCI for over 20 years. I created a single HTML file that uses JavaScript to administer the NASA TLX and output the results.

You can learn more about the NASA-TLX here. My web version is based on a Windows program that performs the NASA-TLX. The main difference in my implementation is I include the scale description alongside each scale. The descriptions were taken verbatim from the original paper and pencil documentation.
