Optical Character Recognition is a technology that sets out to do what the human brain can do almost instantly--convert visual data into textual data. In other words, to read and understand printed text. To a certain extent, todays generation of OCR software manages to recognise most text you can throw at it, but still needs to be babysat.Readiris Pro will, fairly quickly, recognise large blocks of text with deft precision, provided the text is in a monospaced font with no page creases or ink spots which, among other anomalies, will cause unpredictable results. Readiris also has problems recognising certain non-standard fonts such as those used in chapter headings as well as italicised text.
Readiris claims to be over 99 percent accurate when recognising text; however, practice shows it to be a few percentage points off. While 97 percent accuracy looks good on paper it fails to impress when you are being forced to correct the software every time it makes a mistake. Granted, no software which attempts to duplicate a human brain is going be perfect but the quirks that Readiris Pro displays seem so trivial that its a wonder they werent fixed before the product shipped.
When Readiris Pro does find text that it thinks it is misinterpreting, it will pop up a window showing you both the graphical portion of the document where the text in question is located, as well as the softwares best guess of what letter(s) it is trying to recognise. You then have the option to edit what the text is interpreted as, and press either the "Learn" or "Dont Learn" button.
The need to double-check everything you run through Readiris Pro, as well as the interface itself, make scanning multiple-page documents a rather tedious task. Not only is it necessary to run quality assurance procedures on the softwares output, but there is virtually no assistance in the software for scanning large documents like books or essays.
Despite its flaws, however, Readiris Pro proves to be a useful tool for scanning in a page or two here and there, making the time it takes to press a dozen buttons and correct a dozen words much less than it would take to type an entire page. However, without improvements in accuracy and interface, it fails to satisfy when scanning large bodies of text. --Victor Andersen

Having used an old Mustek scanner for some time I decided it was time to treat myself to something better and this model from Visioneer caught my eye.
