[edit] About

This is an implementation of the NASA-TLX task load index.

[edit] Notes

If the script is run with a command line argument -v, the text following v will be used as the task to be rated, and this will appear at the top of the screen and will be saved to the data file.

[edit] Options

You can choose whether to use the 15 pairwise comparisons at the beginning of the scale, by setting

 gDoWeightings <- 1

to

 gDoWeightings <- 0

[edit] Data Output

Data are saved into the file data\tlx-data.csv, with each column a separate rating or pairwise rating.
