Operator assembly dynamic movement amplitude dataset

The provided dataset is based on the joint angle amplitude results of operators' dynamic assembly movement. This file contains data from 12 subjects performing five tasks in 8 different scenarios (either a real workstation or an immersive workstation) during an assembly experiment, with measurements taken for 8 joint angles in 7 different amplitude metrics. The Excel file contains a single sheet, detailed as follows: (1) The two groups of subjects started the experiment either from the real workstation or the immersive workstation, distinguished by different colors. Subjects marked in green indicate those who started the experiment from the immersive workstation, while those without color markings started from the real workstation. (2) The provided file includes information on the subjects' height (cm), subject ID, gender (F/M), profession (Technician/Teacher/Young Engineer), experimental scenario (VR/Real), the number of assembled products completed in each scenario, scenario number, and the amplitude of each joint during the execution of each task. (3) The five assembly tasks in the experiment include: Task 1: Pick the first plate from the toolbox and put it on the assembly support. Task 2: Pick the second plate and align it on the first plate. Task 3: Take the four screws and place them in the plates. Task 4: Take the screwdriver and tighten the four screws. Task 5: Place the assembled product in the toolbox. (4) The 8 joint angles considered in the file include: Right arm flexion, Left arm flexion, Right arm abduction, Left arm abduction, Right lower arm, Left lower arm, Neck, and Hips. (5) The 7 amplitude metrics for joint angles in the file include maximum value, minimum value, max-min, mean, median, standard deviation, and skewness.

本数据集基于操作人员动态装配动作的关节角度振幅结果。该文件包含12名受试者在装配实验中于8种不同场景（真实工作站或沉浸式工作站）下完成五项任务的数据，针对8个关节角度的7种不同振幅指标进行了测量。该Excel文件包含一个工作表，详情如下：（1）两组受试者分别从真实工作站或沉浸式工作站开始实验，通过不同颜色加以区分。绿色标记的受试者表示从沉浸式工作站开始实验，无颜色标记的受试者则从真实工作站开始。（2）文件包含受试者的身高（厘米）、受试者ID、性别（F/M）、职业（技术员/教师/青年工程师）、实验场景（VR/真实）、各场景下完成的装配产品数量、场景编号，以及每项任务执行过程中各关节的振幅信息。（3）实验中的五项装配任务包括：任务1：从工具箱中取出第一块板材并放置于装配支架上；任务2：取出第二块板材并与第一块对齐；任务3：取四颗螺丝并放入板材中；任务4：取螺丝刀并拧紧四颗螺丝；任务5：将装配完成的产品放入工具箱。（4）文件中涉及的8个关节角度包括：右臂屈曲、左臂屈曲、右臂外展、左臂外展、右前臂、左前臂、颈部及髋部。（5）文件中关节角度的7种振幅指标包括最大值、最小值、最大-最小值、均值、中位数、标准差及偏度。
