NASA-TLX Web App:一个在线的主观评价分析工具

NASA-TLX Web App: An Online Tool to Analyse Subjective Workload

Vinoth Pandian Sermuga Pandian, Sarah Suleri

摘要:

NASA任务负荷指数(NASA-TLX)是一种广泛使用的评估技术,用于计算任务期间经历的主观工作负荷。它使用六个维度来评估工作量:心理需求,身体需求,时间需求,挫折,努力和绩效。本文介绍了一个Web应用程序,以协助实验人员使用NASA-TLX来减轻主观工作量。Web应用程序使实验者能够同时进行各种实验,并为参与者提供一个简洁的界面来提供他们的主观评价。它在后端执行计算,并全面提供计算结果。Web应用程序为实验者提供了一个仪表板,以可视化和导出结果摘要。来自12名实验者的定性反馈表明,NASA-TLX网络应用程序是相关的,有用的,易于使用。

英文摘要:

NASA Task Load Index (NASA-TLX) is a widely used assessment technique to compute subjective workload experienced during a task. It evaluates workload using six dimensions: mental demand, physical demand, temporal demand, frustration, effort, and performance. This paper presents a web app to assist experimenters in using NASA-TLX to commute subjective workload. The web app enables the experimenter to conduct various experiments simultaneously and offers the participants a concise interface to provide their subjective evaluation. It performs the calculations at the backend and provides the computed results comprehensively. The web app provides a dashboard for the experimenter to visualize and export the summary of results. Qualitative feedback from 12 experimenters indicated that the NASA-TLX web app is relevant, helpful, and easy to use.
