Dataset of Workers Physiological Responses Under Varied Assembly Conditions

The physiological signals in this study were collected from two participants working in a laboratory setup. The experiment was conducted to simulate an assembly line, where participants had to assemble a box in five steps. While assembling the box participants were exposed to different stimuli designed to enhance their reactions in three psychophysiological states: stress, attention, and visual fatigue. Also, participants performed sessions in which they were not exposed to any stimuli, just to see their normal reaction towards the task. The dataset includes signals derived from cardiovascular and ocular activity. Cardiovascular signals were recorded using an ECG chest band, and ocular signals were captured via eye-tracking glasses. Data files Each .zip file corresponds to one of the two participants. Inside each .zip, you will find four folders: blinks, fixations, saccades, and ECG data. These folders contain .csv files from multiple recording sessions. Each .csv file is organized into columns with features specific to its category (blinks, fixations, saccades, ECG) and generic identifiers such as: Worker ID Experiment Name Event Label Event Group Start End Timestamp The Event Label column indicates the task the participant was performing at a given moment. For eye-tracking data, it may also include information about the stimulus the worker was looking at (e.g., task_name or screen). Similarly, the Event Group column primarily identifies the product numbers handled during that recording session. For eye-tracking data, it can also indicate whether the operator was looking at a product (box) or a screen. For ECG data, the Start and End columns mark the beginning and end of the event described in Event Label, while Timestamp specifies when the data was collected.本研究中的生理信号采集自两名在实验室实验环境中开展实验的受试者。本次实验旨在模拟流水线作业场景，要求受试者分五步完成纸盒组装任务。组装过程中，受试者将接受不同类型的刺激，以获取其在三种心理生理状态下的反应：应激（stress）、注意力集中状态及视觉疲劳状态。此外，受试者还将开展无刺激暴露的对照实验，以获取其执行该任务时的常规反应数据。 本数据集包含源自心血管活动与眼部活动的生理信号。其中心血管信号通过心电（ECG）胸带采集，眼部活动信号则由眼动追踪眼镜获取。 数据文件说明 每个压缩包（.zip）对应一名受试者。每个压缩包内部包含四个文件夹：blinks、fixations、saccades及ECG数据文件夹。这些文件夹内包含多组实验会话生成的.csv格式文件。每个.csv文件按列组织数据，既包含对应类别专属的特征字段，也包含通用标识符字段，具体包括： - 受试者编号（Worker ID） - 实验名称（Experiment Name） - 事件标签（Event Label） - 事件组（Event Group） - 起始时间（Start） - 结束时间（End） - 时间戳（Timestamp） 事件标签（Event Label）列用于指示受试者当前正在执行的任务类型；对于眼动追踪数据，该列还可包含受试者注视的刺激相关信息，例如任务名称或屏幕标识。 事件组（Event Group）列主要用于标识本次实验会话中处理的产品编号；对于眼动追踪数据，该列还可指示受试者当前注视的对象为产品（纸盒）还是屏幕。 针对心电（ECG）数据，起始时间（Start）与结束时间（End）列用于标记事件标签（Event Label）所描述事件的起止区间，而时间戳（Timestamp）则用于指定数据的采集时刻。
