A curated, verified catalog of 73+ sign language datasets covering 26 sign languages โ the most comprehensive open collection for sign language recognition (SLR) research, gesture recognition, deaf community technology, and assistive AI development.
๐ฏ Mission
To democratize access to sign language technology by providing:
- Verified dataset links โ every URL checked, sample counts from original sources
- Working tools for loading, visualizing, and processing data
- Demo datasets for learning and prototyping
- Proper attribution to all data creators
Helping developers, researchers, and the deaf community build better assistive technology.

- โ Every dataset has a citation or credit to its creator
- โ No placeholder or fabricated links exist in the active catalog
- โ Datasets we couldnโt verify are excluded (not listed with fake info)
Found a broken link? Please open an issue.

๐ Quick Start
Clone & Setup
git clone https://github.com/rudra496/SignLanguage-Dataset-Hub.git
cd SignLanguage-Dataset-Hub
pip install -r requirements.txt
Use the Demo Data (Bangla Sign Language Sensor Data)
from scripts.data_loader import BdSLSensorGloveDataset
# Load demo sensor data (4,824 samples)
dataset = BdSLSensorGloveDataset(split='train')
print(f"Loaded {len(dataset)} samples, 36 gesture classes")
sample = dataset[0]
print(f"Gesture: {sample['gesture_name']}")
print(f"Sensors shape: {sample['sensors'].shape}")
Visualize Sensor Data
python tools/visualize.py --data data/bdsl/BdSL-Sensor-Glove/
Browse Programmatically
import pandas as pd
df = pd.read_csv('datasets_catalog.csv')
# Filter by language
asl = df[df['language_code'] == 'ASL']
print(asl[['name', 'samples', 'source_url']])
# Filter by modality
video = df[df['modality'].str.contains('Video')]
print(f"Video datasets: {len(video)}")
