There are several methods for entering data into your computer. Some include the use of a mouse, of which there are several different types, such as the mechanical mouse, the optical mouse, and the wireless mouse. It also has a touchpad and joysticks. Here are some other unconventional pen input devices.

Light Pen: The light pen is actually one more signaling input device. This will detect the existence of light. It is a pen-shaped handheld device that has a photocell installed on its interface. Once the front end of the pen is actually touched on the display screen, the actual photocell registers a position associated with the display. This type of instrument also offers a button. An individual points to the actual object that will end up being chosen on the screen with the stylus and then clicks on the stylus button. Light pen devices are used by technical engineers, visual creative designers, etc. These types of gadgets require unique displays. The stylus can be used in PDAs and also in other types of notebook computers.

The electric light pen input instrument is usually combined with the creation of computer software. The designed screen data files are generally joined using a stylus simply by directing it to the viewing positions. A new spot appears on the screen in the area exactly where the stylus is placed that is detected through the photocell. The PC software operated the feedback transmission of the instrument.

Digitizer – A digitizer is also called a graphics tablet and uses a pen input device. It is a flat digital plastic material pad in the shape of a rectangle. Each digitizer position points to a matching video screen. It is mainly useful for producing road maps and engineering drawings as well. The stylus and cursor of the actual input devices can be used to draw sketches and drawings to the digitizer.

Whenever you draw on the digitizer with the help of the stylus or cursor, this converts the actual actions associated with the stylus or cursor directly into electronic signals which are then sent to the laptop or computer. Thus, a digitizer simplifies the task of typing freehand sketches on a laptop or computer.

Stylus and Cursor: The stylus is actually like a pen. It is used to compose textual content or make lines (or generate drawings and also images) on the screen or graphics digitizer developed exclusively. The pen input devices found in various sophisticated graphics devices are called digital pens. Generally, the electronic digital pen provides much higher performance compared to the stylus.

The stylus can be used in graphics programs, for example, computer-aided design (CAD), and also in engineering drawings, etc. It has the convenience of removing textual content and lines.

Several portable personal computers use touch screens that allow someone to enter any data and even enable selections on the monitor using a stylus or digital pen. PDAs use pen input devices in conjunction with tablets. Computers often use a digital pen. This laptop or computer operates one-of-a-kind platforms, also known as Optical Character Recognition. This program converts the characters written together with the symbols in a way that the computer systems can use and also process them all.

The actual cursor is surely an input product. It is also used to draw sketches and also drawings with a graphics tablet or perhaps a digitizer. This looks like a kind of computer mouse, except that it has a window that uses a crosshair, so the end user can see the actual digitizer. The cursor is generally known as the Puck.
