A pen tablet, also called a graphics tablet, digitizer, or drawing tablet is used to draw on or trace images from papers that are put on the flat surface of the tablet. It is usually connected to a computer at a USB port, but some models have a computer screen that shows the image right on the tablet. A pen is used to make graphics or draw pictures, much like a pen or pencil is used on paper. Another function of this device is digitizing, which is tracing an image from paper that is taped to the surface of the tablet. The pen is sometimes used instead of a mouse to navigate on the monitor. It is much easier to go to a particular spot on the monitor with the pen as opposed to a mouse. This feature is especially useful to artists and designers who work on pen tablets throughout the day.
There are many different models available, including those for children that typically have the pen attached to the tablet with a cord. Tablets are often used by technical designers and for computer-aided design (CAD) that is computer drafting or design. Because the exact location is extremely necessary for these jobs, a puck may be used to manipulate the line on the tablet instead of a pen. Pucks may look similar to a mouse, but they can have many buttons that aid in locating a precise spot for technical uses. These tablets make writing in Chinese, Japanese, or Korean easier for residents of these countries who use them to write rather than typing on a keyboard.
Teachers also use pen tablets connected to a projector with notes that they have written, graphs, and other teaching aids on them. Educators who teach online also use tablets to explain complex information to students via the Internet. Students can copy the notes from the screen or the whiteboard. Interactive whiteboards are capable of producing wall size graphics that students can work from. Pen tablets are also often used by artists who create digital drawings and by photographers who use photo software to create digital graphics.
