Palm Sign

Palm Sign is a camera-based web application that transforms a user’s palm or hand pattern into a customizable digital signature-style graphic. Using the device camera and MediaPipe Hand Landmarker, the application detects hand landmarks and extracts normalized geometric data. This data is processed to generate smooth, artistic signature designs. Users can customize the signature’s style, ink color, stroke width, size, rotation, and background. The generated signature can be previewed and downloaded in formats such as PNG, transparent PNG, SVG, and JPEG. Palm Sign is designed with a clean, responsive, and accessible interface using Next.js, React, TypeScript, and Tailwind CSS. Privacy is prioritized by avoiding the storage of raw camera footage, frames, or palm photographs. The application also includes a demo mode when camera detection is unavailable. The generated result is a digital graphic and does not claim legal validity, biometric authentication, identity verification, or guaranteed uniqueness.
