+# Palmpad Dataset
+
+The Palmpad Dataset is a publicly available multimodal dataset designed for research in finger-to-palm recognition. This dataset contains data from users, divided into two groups (Group 1 and Group 2). Each user's data consists of multiple video files in .avi format, along with corresponding frame-level annotation files in .txt format.
+
+## Overview
+Paper Title: Palmpad: Enabling Real-Time Index-to-Palm Touch Interaction with a Single RGB Camera
+
+## Dataset Content
+
+Each data sample includes a .avi video file and a corresponding .txt annotation file with frame-level labels.
+The dataset is divided into two groups.
+Applications: Finger-to-Palm Recognition
+
+## Dataset Structure
+The dataset is organized as follows:
+
+Palmpad_Dataset/

+
+File Descriptions
+group_1/ and group_2/: The dataset is split into two groups, each containing data from 16 users.
+user-{id}/: Data for each user is stored in a separate folder.
+user-{id}_{index}.avi: Video file capturing the user's action.
+user-{id}_{index}.txt: Frame-level annotation file corresponding to the video.
+
+Annotation Format
+The annotation files are plain text, where each line corresponds to a frame in the video. The format is as follows:
+<Timestamp> <downsample> <raw>
+<Timestamp>: The frame timestamp for each frame.
+<downsample>: The label of touch(1) or not(0) for the corresponding frame.
+<raw>: Middle value for calculate the label.
+
+Example:

+1691995008126552 0 0
+1691995008134885 0 0
+
+## Dataset Statistics
+User number: 16 users in Group 1, 16 users in Group 2.
+Average Data per User: Each user has multiple video files and corresponding annotation files.
+Video Resolution: 1280x720
+Video Frame Rate: 120 FPS
