ACTi Graphs: Data Collections from Physiological Experiments on Stress and Energy Expenditure

This database brings together data collected from ActiGraphs worn by test participants. Each participant wore three ActiGraphs placed on the ankle, waist, and wrist during the tests. The published data has been pre-processed using ActiLife software. This database enabled comparisons between energy expenditure, the number of mistakes made, and participants' self-reported stress levels.
The data is organised into folders, each corresponding to a specific participant. Within each participant’s folder, there are three subfolders and a file. The subfolders contain pre-processed data from the ActiGraphs, categorised by the body location where each sensor was worn (ankle, waist, and wrist). The file named "performance.xlsx" provides details on the participant's performance during the test.
The pre-processed ActiGraph files display the counts from the sensor axes. These counts are calculated by ActiLife software, using a proprietary method that the company has not disclosed. Additional information, such as inclinometer readings and step counts, is also included in these files, although this data was not used in the study.
The "performance.xlsx" file outlines the conditions and results of each task performed by the participants. It specifies the start and end times of each task, the number of errors made, and details about environmental and noise conditions ("Temperature" and "Noise"). This file also contains participants’ responses to a stress questionnaire administered at the end of each task. The questionnaire is available in the attached document titled "Stress Questionnaire.pdf". Additionally, the "NoStress_Processing.py" Python script is provided for data processing.

本数据库汇聚了测试参与者佩戴的ActiGraph收集的数据。每位参与者均在测试期间于脚踝、腰部和手腕处佩戴了三个ActiGraph。发布的数据已通过ActiLife软件进行预处理。该数据库实现了对能量消耗、所犯错误次数以及参与者自我报告的压力水平的比较研究。数据被组织成文件夹，每个文件夹对应一位特定的参与者。在每位参与者的文件夹中，包含三个子文件夹和一个文件。子文件夹中存储了来自ActiGraph的预处理数据，按照传感器佩戴的身体部位（脚踝、腰部和手腕）进行分类。名为“performance.xlsx”的文件提供了参与者测试期间表现的详细信息。预处理后的ActiGraph文件显示了传感器轴的计数，这些计数由ActiLife软件根据公司未公开的专有方法计算得出。此外，这些文件还包含了如倾斜仪读数和步数等附加信息，尽管这些数据未在研究中使用。名为“performance.xlsx”的文件概述了参与者完成的每个任务的条件和结果，包括每个任务的开始和结束时间、所犯错误次数，以及环境噪声条件（“温度”和“噪声”）的详细信息。该文件还包含了在每个任务结束后进行的压力问卷的参与者回答。问卷可在附带的文件“压力问卷.pdf”中找到。此外，还提供了用于数据处理的Python脚本“NoStress_Processing.py”。
