What kind of computer device is a digitizer?

The digitizer is the input device of the computer. It can accurately input various graphics into the computer according to the coordinate values ​​and display them on the screen. The digitizer converts the continuous analog quantities of images and graphics into A discrete digital device is a very versatile graphic input device in professional applications.

The digitizer is a computer input device that can accurately input various graphics into the computer based on coordinate values ​​and display them on the screen.

A digitizer is a device that converts continuous analog quantities of images (film or photos) and graphics (including various maps) into discrete digital quantities. It is a very widely used instrument in professional applications. Graphical input device. When the user moves the cursor on the electromagnetic induction plate to the designated position and aligns the intersection of the cross with the digitized point, and presses the button, the digitizer will arrange the corresponding command symbol and the position coordinate value of the point. into an ordered set of information, and then transmitted to the host computer through the interface (multipurpose serial interface). To put it more simply and popularly, a digitizer is a large-area handwriting tablet. Users can write or draw graphics on it with a special electromagnetic induction pressure-sensitive pen or light pen, and transmit it to the computer system. However, it is very different from the handwriting tablet in terms of software support, and the hardware design also has its own preferences.

Purpose

In many professional application fields, users need to draw large-area drawings, which cannot be achieved by relying on CAD systems alone. Completely completed drawings will also have large deviations in accuracy, so a digitizer must be used to meet the user's needs. High-precision digitizers are suitable for geology, surveying, mapping, land and other industries. Ordinary digitizers are suitable for industries such as engineering, machinery, and clothing design.
