What is the acceptable workload score for the NASA-TLX protocol?
The NASA-TLX protocol was used to measure the MW impact. According to [Eitrheim and Fernandes 2016], the perceived workload score for both languages are acceptable (i.e., ≤ 50).

Is the NASA-TLX a good measure of workload cost?
A number of subjective, self-report workload measures exist, but the National Aeronautics and Space Administration-Task Load Index (NASA-TLX) is probably the most well known and used. The aim of this paper is to consider the workload costs associated with the computer-based and paper versions of the NASA-TLX measure.

What is a good Sus score on the NASA TLX?
SUS does not answer this, it is purely a classification tool to indicate if the application in question is usable, and it is not used for diagnostic purposes.The final scores for the NASA TLX (Fig. 7) show a varied range with a low score of 18 to a high score of 38, the mean average for this is 27.1.

What is the NASA task load index?
Description: The NASA task load index (NASA TLX) is a tool for measuring and conducting a subjective mental workload (MWL) assessment. It allows you to determine the MWL of a participant while they are performing a task. It rates performance across six dimensions to determine an overall workload rating.

What is the NASA TLX?
The NASA TLX is a multi-item questionnaire developed in 1980 by Sandra Hart. NASA is, of course, the US-based space agency famous for the one giant leap for mankind. The TLX stands for Task Load Index and is a measure of perceived workload.

Where can I download the task load index (TLX) app?
This app is available only on the App Store for iPhone and iPad. The Official NASA Task Load Index (TLX) App, widely regarded as the gold standard for measuring subjective workload across a wide range of industries, enables researchers to easily perform assessments on operators working with various human-machine interface systems.

What is the NASA task load index?
NASA Task Load Index. Hart and Staveland’s NASA Task Load Index (TLX) method assesses work load on five 7-point scales. Increments of high, medium and low estimates for each point result in 21 gradations on the scales.

What is the NASA TLX app for iOS?
The NASA TLX app for iOS dramatically increases the outreach and accessibility for the research and development community, and enables mobile and contextual assessments (e.g., in an airplane cockpit during/after flight, rather than at a desktop computer in a lab). It offers several key features that benefits both researchers and participants:
