Development of NASA-TLX (Task Load Index): Results of Empirical and Theoretical Research
Abstract The results of a multi-year research program to identify the factors associated with variations in subjective workload within and between different types of tasks are reviewed. SubjectiveExpand
Nasa-Task Load Index (NASA-TLX); 20 Years Later
NASA-TLX is a multi-dimensional scale designed to obtain workload estimates from one or more operators while they are performing a task or immediately afterwards. The years of research that precededExpand

TLDR
This booklet contains the materials necessary to collect subjective workload assessments with the NASA Task Load Index and a bibliography provides background information about previous empirical findings and the logic that supports the procedure. Expand
Workload Assessment and Prediction
TLDR
The concept of workload and its relationship to performance is introduced in this chapter and four categories of workload measurement techniques are reviewed, examples of each category are described, and their strengths and weaknesses are summarized. Expand

  • 1 May 1987
TLDR
Communications performance, subjective ratings, and heart rate were tested during 11 routine missions conducted by the NASA Kuiper Airborne Observatory, providing an objective indicator of pilot workload. Expand
Field Test of Video Game Trainer
A field study was conducted at the US Army Aviation Center to determine whether workload-coping and attention-management skills developed through structured video game experience would generalize toExpand
Measuring pilot workload in a motion base trainer. A comparison of four techniques.
TLDR
Four widely used methods to predict and measure pilot workload were compared: a visual two-and four-choice reaction time task, time production, retrospective multi-dimensional subjective ratings and in-flight verbal workload estimates. Expand
