# HarassGuard Dataset

## Social VR Harassment Behavior Video Dataset

The **HarassGuard Dataset** is a vision-based video dataset developed for detecting physical harassment behaviors in Social Virtual Reality (Social VR) environments using visual information.

The dataset was collected through the user study conducted for the following paper:

> **HarassGuard: Detecting Harassment Behaviors in Social Virtual Reality with Vision-Language Models**  
> Junhee Lee, Minseok Kim, Hwanjo Heo, Seungwon Woo, Jinwoo Kim  
> IEEE VR 2026

- **IRB Approval:** Kwangwoon University Institutional Review Board  
  (No. 7001546-20250630-HR(SB)-006-06)
- **Number of Video Clips:** 1,116 (`.mp4`)
- **Resolution / Frame Rate:** 1280 × 720 / 30 fps (H.264)
- **Data Collection Period:** August 20–27, 2025
- **Access:** Controlled access for non-commercial academic and research use

---

## 1. Dataset Overview

The HarassGuard Dataset contains video recordings of avatar interactions in Social VR environments.

Harassment behaviors are organized into **three major harassment categories**, together with a **Benign** category representing normal interactions.

All behavior labels are defined based on interactions between avatars. Background activities, such as normal gameplay unrelated to harassment, are excluded from harassment labeling.

### Behavior Categories

| Category | Subcategory | Definition |
|---|---|---|
| **Aggressive Behavior** | Punching | Striking another avatar with a fist |
| | Slapping | Striking another avatar with an open hand |
| | Hitting with Object | Striking another avatar using an object |
| | Punching & Slapping | A combination of punching and slapping behaviors; present only in the Communication Room |
| **Personal Space Violation** | Looming | Moving excessively close to another avatar's face |
| | Following / Stalking | Continuously following another avatar |
| **Disruptive Behavior** | Blocking | Physically obstructing another avatar's movement |
| **Benign Behavior** | — | Normal interactions such as conversation, rock-paper-scissors, walking, and other non-harassing activities |

Each participant spent approximately **1 hour** completing the study, including preparation and VR experience.

### Pre-experiment Training

Participants received:

- approximately **5 minutes** of training on the VR headset and controllers; and

## 5. Recording Environment

### VR Environment

- **Engine:** Unity 2022.3.22f1

Full-body avatars were represented using:

- upper-body tracking; and
- **Inverse Kinematics (IK)** to reproduce lower-body movements.

### Camera Configuration

The recording environment consisted of:

- **four third-person omnidirectional cameras** (`3PoV_1`–`3PoV_4`); and
- **one first-person camera** (`1PoV`).

All video streams were recorded directly on the server.

## 8. Controlled Access

Because the HarassGuard Dataset contains video data collected from human participants as part of an IRB-approved user study, the original video files are **not available through unrestricted public access**.

The dataset is distributed through the Hugging Face Hub as a **gated dataset with manual review**.

Access is intended for researchers affiliated with recognized universities, research institutes, or other bona fide research organizations who wish to use the dataset for **non-commercial academic and research purposes**.

Each access request is reviewed individually by the dataset providers. Approval is not automatic.

### Access Request Information

Hugging Face automatically provides the requester's account username and email address to the dataset providers. The gated access form additionally requests:

- institution;
- department or laboratory;
- position;
- principal investigator or faculty supervisor;
- institutional email address;
- research project title;
- intended research use; and
- IRB / research ethics information, if applicable.

Applicants must also explicitly agree to the key requirements of the **HarassGuard Research Data Use Agreement (DUA)**.

Use of an institutional email address is strongly recommended. The dataset providers may request additional information to verify institutional affiliation or the proposed research purpose.

## 9. Terms of Use

Access to the original video dataset is governed by the:

> **HarassGuard Research Data Use Agreement (DUA)**

See [`DATA_USE_AGREEMENT.md`](./DATA_USE_AGREEMENT.md) for the complete terms.

In summary:

- The dataset may be used only for **non-commercial academic and research purposes**.
- Machine-learning and AI model training and evaluation are permitted.
- Normal research preprocessing, including frame extraction, resizing, cropping, annotation, and feature extraction, is permitted.
- Redistribution of the original videos is prohibited.
- Public uploading of the original videos or substantial portions of the dataset is prohibited.
- Researchers must not attempt to identify or re-identify study participants.
- Dataset access must be restricted to approved research-team members.
- The dataset must be stored using reasonable security measures.
- Publication of original video clips, screenshots, extracted frames, or other visual excerpts requires prior written permission from the dataset provider.
- Research publications using the dataset must appropriately cite the HarassGuard paper.

The above is only a summary. The complete terms in `DATA_USE_AGREEMENT.md` govern use of the original video dataset.

Derived data that contains substantial portions of the original videos, permits practical reconstruction of the original videos, or may compromise participant privacy must **not be publicly redistributed without prior written permission**.

---

## 11. Research Ethics and Privacy

The HarassGuard Dataset originates from an IRB-approved human-participant study.

Researchers receiving the dataset are responsible for determining whether their proposed secondary use requires additional approval, exemption, or review by their own **Institutional Review Board (IRB), Research Ethics Committee, or equivalent authority**.

Researchers must not attempt to identify or re-identify any participant.

The dataset must not be used for surveillance, profiling, harassment, discrimination, or other purposes unrelated to the approved research.

Researchers are responsible for complying with all applicable institutional policies, ethical requirements, and laws governing their use of the dataset.

---

## 12. Data Security and Third-Party Services

Researchers must store the original video data using reasonable technical and organizational safeguards.

Original videos should not be transferred to third-party services, including external cloud-based AI or vision-language-model APIs, unless such transfer is permitted by:

1. the HarassGuard Research Data Use Agreement;
2. the researcher's applicable IRB / ethics approval or exemption;
3. the researcher's institutional policies; and
4. the third-party service's data-processing, retention, and privacy terms.

Researchers remain responsible for ensuring that any permitted third-party processing does not result in unauthorized retention, disclosure, redistribution, or use of the original video data.
