-· Contains 5000 images of cockpit user behavior, generated by the XAI Lab dataset generation engine.
-· The data set contains images of users of different ages, genders, races, and clothing, covering different expressions, behavioral actions, and tags. 
-· It can be used for fine-tuning training of intelligent cockpit end-side vision model and OMS/DMS algorithm, so that the model can obtain the ability to identify and understand the behavior of intelligent cockpit passengers.

+The world’s largest open-source, high-quality multimodal dataset for smart-cockpit perception is here!
+
+1. Dataset Summary  
+“CyberData Saita” is a high-fidelity, programmatically generated image dataset created to accelerate the development of in-cabin perception algorithms. With global automotive safety regulations such as C-NCAP and EU GSR imposing stricter requirements on Driver-Monitoring Systems (DMS) and Occupant-Monitoring Systems (OMS), safe, compliant and diverse training data has become critical. By leveraging synthetic generation, this dataset overcomes key challenges faced in real-world data collection—namely privacy risks, high costs and insufficient coverage of long-tail scenarios.
+
+The dataset contains 5,000 photo-realistic cabin images synthesized by XAI Lab’s proprietary generation engine. Every image is accompanied by rich, 100 % accurate annotations.
+
+Key features  
+• Rich scene diversity: spans virtual humans of different ages, genders, ethnicities and clothing styles, together with a wide range of driving/riding behaviors (e.g., phone use, drinking, fatigue, gestures) and facial expressions.  
+• Optimized for in-cabin perception: ready for on-device vision models in smart cockpits, especially for training, fine-tuning and validation of DMS/OMS algorithms that must precisely interpret complex interactions and occupant states.  
+• Safe & compliant data source: all images are purely synthetic, eliminating privacy and portrait-right issues inherent in real-user data collection, and providing a secure, controllable and scalable data foundation.  
+• Accurate programmatic labels: all tags (bounding boxes, behavior classes, user attributes) are generated synchronously with the images, yielding zero annotation errors and perfect consistency while removing human subjectivity.
+
+2. Supported Tasks & Leaderboards  
+This dataset aims to advance computer-vision technologies inside the cabin, particularly for active safety and intelligent interaction of drivers and passengers.
+
+Main tasks  
+• Behavior Recognition: classify critical occupant behaviors (e.g., using_phone, smoking, drinking, yawning) via image-level multi-label classification—vital for detecting distracted or dangerous driving.  
+• Driver State Monitoring: assess physiological/mental state (drowsy, distracted, attentive) to help prevent fatigue-related accidents.  
+• Object Detection: localize key objects such as faces, hands and phones via bounding-box regression.  
+• Attribute Recognition: identify basic demographic attributes (age_group, gender) to enable personalized cabin settings.
+
+Leaderboards (planned)  
+We intend to host future challenges and publish leaderboards that rank the best-performing models on a standardized test set. Evaluation metrics will likely include:  
+• Behavior recognition: mAP (mean Average Precision)  
+• Object detection: mAP@0.50  
+• State monitoring: F1-Score, Accuracy
+
+3. Dataset Structure  
+The dataset follows a clear, intuitive directory layout for easy access and parsing. All images are stored in images/; the corresponding JSON annotations reside in annotations/.
+
+Data instance  
+Each sample consists of one .jpg image and a matching .json file with identical filenames. Below is an example annotation (<image_id>.json):
+
+{
+  "image_path": "images/0001.jpg",
+  "image_id": "0001",
+  "attributes": {
+    "age_group": "25-35",
+    "gender": "male",
+    "race": "asian",
+    "clothing": "t-shirt"
+  },
+  "annotations": [
+    {
+      "label": "face",
+      "bbox": [250, 150, 450, 350],
+      "expression": "neutral"
+    },
+    {
+      "label": "behavior",
+      "class": "using_phone",
+      "bbox": [300, 400, 500, 600]
+    },
+    {
+      "label": "drowsiness",
+      "class": "none",
+      "confidence": 0.98
+    }
+  ]
+}
