+
+## 📖 Introduction
+**HapticCap** is a multimodal dataset and benchmark task designed for understanding **user experience of vibration-based haptic signals**.  
+It provides a new resource for research at the intersection of **haptics, text, and multimodal learning**.
+
+---
+
+## 📂 Dataset
+- **Modality**: Vibration haptic signals, paired with textual annotations  
+- **Textual Annotations**:  
+  - Sensory: It refers to physical attributes (e.g.,intensity of tapping).
+  - Emotional: It refers to emotional denotes affective impressions (e.g., the mood of a scene).
+  - Associative: It indicates real-world familiar experiences (e.g., buzzing of a bee, a heartbeat).
+ 
+- **Format**: Signals stored as time-series data; annotations in JSON with haptic signal ID  
+- **Scale**:

+
+## 🧩 Tasks
+- Haptic-caption retrieval: Its objective is to retrieve the textual descriptions of three categories that correspond to a given haptic signal, using the
+haptic signal as the query and the descriptions as the target documents.

+
+## 🧩 Models
+We design supervised contrastive learning framework that aims to pull the clusters of points belonging to the same class together in an embedding space and simultaneously
+pushes apart clusters of samples from different classes.
