Emotion-Induced Body Motion and Ground Reaction Force Data with Full-Body Motion Capture

This dataset contains comprehensive recordings of body motion and ground reaction forces collected during an experiment designed to study the effects of emotional stimuli on human movement. The experiment involved participants viewing emotionally charged movies while standing on a force plate, and their body motion was captured using a full-body motion-capture system.

Experimental Setup:
Participants: Individuals were exposed to different emotional conditions through a series of movies.
Stations:
Start Station: A force plate (OR6-7-2000 AMTI) where participants stood while watching the movies.
Station A: A 55-inch TV screen, 2 meters from the force plate, where the movies and instructions were presented.
Station B: A sitting station, 4 meters from Station A, where participants performed filler tasks between emotional conditions.
Procedure: Participants moved between stations according to the experimental protocol. Body motion was recorded during movie viewing and walking phases, with special emphasis on post-movie emotional manipulation checks.
Data Collection:
Motion-Capture System: A total of 14 cameras (Oqus 300 and Oqus 500 by Qualisys) were used to track the body movements of participants.
Marker Placement: 22 reflective markers were placed on key anatomical points (e.g., head, shoulders, elbows, wrists, hips, knees, ankles, toes, and heels) to capture a full-body model.
Ground Reaction Forces: Data was captured via the force plate, recording forces and center of pressure (COP) at a rate of 120Hz while participants stood to watch the movies.
Data Files:
Subject Data: Each participant's data is stored in a dedicated folder with the naming convention <subject_id>_<trial_num>.<extension>.
C3D Files: 3D motion capture data.
QTM Files: Data from the Qualisys Track Manager.
TSV Files: Tab-separated value files with force plate data and marker positions along three axes.
Exp_data.xlsx: Contains metadata including subject IDs, trial numbers, corresponding emotions, age, gender, and questionnaire responses.
Purpose:
The dataset is designed to support research in biomechanics, emotion studies, and human movement analysis. It is particularly suited for studies aiming to understand the relationship between emotional states and physical movement patterns.

Potential Uses:
Analysis of emotion-induced changes in body motion and balance.
Studying the impact of different emotional states on ground reaction forces.
Development of machine learning models for emotion detection based on motion capture data.
Multimodal analysis combining motion capture data with psychological assessments.

本数据集包含为探究情绪刺激对人类运动的影响而开展的实验中采集的全身运动与地面反作用力（ground reaction forces）的完整记录。实验过程中，参与者站在测力平台上观看情绪诱发类影片，同时通过全身运动捕捉系统（full-body motion-capture system）采集其身体运动数据。

### 实验设置
参与者：通过一系列情绪诱发影片接受不同情绪条件刺激。

实验站位：
- 起始站位：测力平台（OR6-7-2000 AMTI），参与者在此站立观看影片。
- 站位A：距测力平台2米处设置55英寸电视屏幕，用于播放影片及展示实验指导。
- 站位B：距站位A4米处设置坐席，供参与者在不同情绪条件间完成填充任务。

### 实验流程
参与者按照实验规程在各站位间移动。实验记录了影片观看与行走阶段的身体运动数据，重点关注观影后情绪操控有效性检验环节。

### 数据采集
1. 运动捕捉系统：共采用14台Qualisys公司生产的Oqus 300与Oqus 500型号摄像头，追踪参与者的身体运动。
2. 标记点布置：在头部、肩部、肘部、腕部、髋部、膝部、踝部、脚趾与足跟等关键解剖点位布设22个反光标记点，以构建完整的全身运动模型。
3. 地面反作用力：参与者站立观影期间，通过测力平台采集数据，以120Hz的采样率记录作用力与压力中心（center of pressure, COP）信息。

### 数据文件
- 受试者数据：每位受试者的数据存储于专属文件夹，命名格式为<subject_id>_<trial_num>.<extension>。
- C3D文件：三维运动捕捉数据。
- QTM文件：Qualisys Track Manager导出的运动追踪数据。
- TSV文件：制表符分隔值格式文件，包含测力平台数据与标记点三轴位置信息。
- Exp_data.xlsx：包含元数据，涵盖受试者ID、试验次数、对应情绪类型、年龄、性别与问卷反馈结果。

### 数据集用途
本数据集旨在为生物力学、情绪研究与人类运动分析领域的研究提供支撑，尤其适用于探索情绪状态与身体运动模式之间关联的相关研究。

### 潜在应用场景
1. 分析情绪诱导的身体运动与平衡变化。
2. 研究不同情绪状态对地面反作用力的影响。
3. 开发基于运动捕捉数据的情绪识别机器学习模型。
4. 结合运动捕捉数据与心理评估的多模态分析。
