NAME

nasa-tlx : NASA Task Load Index (TLX) calculator

DESCRIPTION

This program calculates the NASA task load index (TLX) as published by 
S. Hart circa 1985. It uses the weighted average method, as opposed to more
recent versions of the index that dispose of the factor weights. It's
implemented in Python and makes use of wxWidgets/wxPython for the user
interface. The only external library required to run the program is
wxPython.

SOFTWARE DEPENDENCIES

Python
wxPython

INSTALLATION

No installation is required at this time. The only method of running the
program currently is directly from the 'src' directory in the distributed
tarball.

USAGE

Calculating a TLX score with this program is extremely easy. First, start
the program from the 'src' directory in the contents extracted from the
distributed tarball:

    $ ./main.py

The 'main.py' script will start a window titled NASA-TLX containing
controls to adjust calculation parameters for the TLX score. The first
section adjusts factor weights based on pair comparison of individual
factors. The second section adjusts factor magnitudes. These sections and
their use are described by S. Hart et. al., 1988.

The program calculates the TLX score each time a factor is selected or
magnitude changed.

NOTE: at this time 'main.py' must be started from the 'src' directory.
