Simply pass the nib across a word and it instantly displays the definition and reads it aloud. It is also a scanner for capturing lines of text and uploading to a PC or Mac, making it ideal for students, teachers and professionals to capture essential information. The pen is half the size of other portable pen scanners on the market and at 50g is half the weight. This is the only portable line scanner on the market that is both Mac and PC compatible. There is no software required, just connect the pen up to a computer with a USB cable and it appears as an external hard drive.

Optical character recognition or optical character reader OCR is the mechanical or electronic conversion of images of typed, handwritten or printed text into machine-encoded text, whether from a scanned document, a photo of a document, a scene-photo for example the text on signs and billboards in a landscape photo or from subtitle text superimposed on an image for example from a television broadcast. Widely used as a form of information entry from printed paper data records — whether passport documents, invoices, bank statements , computerized receipts, business cards, mail, printouts of static-data, or any suitable documentation — it is a common method of digitizing printed texts so that they can be electronically edited, searched, stored more compactly, displayed on-line, and used in machine processes such as cognitive computing , machine translation , extracted text-to-speech , key data and text mining. OCR is a field of research in pattern recognition , artificial intelligence and computer vision. Early versions needed to be trained with images of each character, and worked on one font at a time. Advanced systems capable of producing a high degree of recognition accuracy for most fonts are now common, and with support for a variety of digital image file format inputs. Early optical character recognition may be traced to technologies involving telegraphy and creating reading devices for the blind. In the late s and into the s Emanuel Goldberg developed what he called a "Statistical Machine" for searching microfilm archives using an optical code recognition system.

A digital image is a picture that is stored on a computer. It has been digitised, which means it has been changed into a sequence of numbers that computers can understand. There are a few ways you can make a digital image. You could create one in a piece of design software like Paint or Photoshop , take one on a digital camera or scan one in using a scanner. Lots of these pixels together can form a digital image. Each pixel has a specific number and this number tells the computer what colour the pixel should be. The process of digitisation takes an image and turns it into a set of pixels.

Optical character recognition or optical character reader (OCR) is the mechanical or electronic conversion of images of typed, handwritten or printed text into Early optical character recognition may be traced to technologies involving for the blind, which would allow blind people to have a computer read text to them out.

Such devices make up the peripheral equipment of modern digital computer systems. Peripherals are commonly divided into three kinds: input devices, output devices, and storage devices which partake of the characteristics of the first two. An input device converts incoming data and instructions into a pattern of electrical signals in binary code that are comprehensible to a digital computer. An output device reverses the process, translating the digitized signals into a form intelligible to the user. At one time punched-card and paper-tape readers were extensively used for inputting, but these have now been supplanted by more efficient devices. Input devices include typewriter-like keyboards; handheld devices such as the mouse , trackball, joystick, trackpad, and special pen with pressure-sensitive pad; microphones, webcams, and digital cameras.

Suppose you wanted to digitize a magazine article or a printed contract. You could spend hours retyping and then correcting misprints. Or you could convert all the required materials into digital format in several minutes using a scanner or a digital camera and Optical Character Recognition software. The exact mechanisms that allow humans to recognize objects are yet to be understood, but the three basic principles are already well known by scientists — integrity, purposefulness and adaptability IPA. First, the program analyzes the structure of document image. It divides the page into elements such as blocks of texts, tables, images, etc.
