A sketching tablet, also known as a drawing PAD or graphics tablet, is a computer input device that allows users to draw images and graphics directly onto a computer. It consists of a flat surface, usually made of plastic, with a stylus or pen-like device used to draw on the surface. The most common type of sketching tablet is the PAD, which stands for Pressure-Sensitive Digital Tablet. This type of tablet is designed to detect the pressure applied by the user's hand and convert it into digital signals that can be interpreted by the computer. This allows for more precise control over the lines and shapes created on the screen.
