If you would like to use the NASA TLX tool, but do
not want to use the iOS app, it is available here
in its original paper and pencil format. This tool is just as powerful
as the computerized version, and will be just as helpful in your workload
analysis. Before you use the scale, however, be sure to download
and thoroughly review the instruction manual.
This will ensure that
you are using the scale correctly and will allow you to accurately decipher
the data you collect. For example, you will find the comparison cards to use in conjunction with the TLX Scale inside the instruction manual.
The NASA TLX tool is “open source”, and is therefore available for immediate use by any person or organization (worldwide). It is not necessary to obtain permission from NASA to use TLX, nor is permission needed to make modifications to the tool itself (i.e. language translation).
