In my research i started looking into the various CAPTCHA’s and tried out whether one could mimic some of the visual tools applied by such software.

Going back to earlier mentioned OCR-A font I find it interesting to see how the CAPTCHA actually operates in the same intersection between human and computers, just here the goal seems to be the exact opposite in actually striving to avoid OCR-software to be applied. The aim is to simply create a text which a person but not a computer could decipher, thus telling the two apart. A small box with hard to read text from which the user is supposed to decipher the letters in order to enter a certain webpage. Īs a tool to avoid this the “ CAPTCHA” was invented. The number of spam e-mails is estimated to be around 200 billions a day.

Bots with algorithms designed to sign up for free emails in the count of several thousands, to send out millions of so called “ spam” e-mails turned out to be one of the problems that the internet encountered. Cause as we surf around the internet so does computers. Text and images crossing the globe in split second enables us to pass the physical boundaries of time and space.īut let’s stay grounded for a second. However taking a leap from 1968 to todays society, OCR-software are now able to recognize almost any text in no time, let alone the fact that a vast amount of information all ready exist in digital format and might very well never enter the physical world as printed matter.īeing a child of the 90’s myself, my generation have been brought up in a time were the development of the computer and the internet and the digitization and accessibility of information that it brought along has truly underwent extraordinary progress. This I believe is an important point which I will return to later in the connection with CAPTCHA’s (an acronym for “Completely Automated Public Turing test to tell Computers and Humans Apart”). The general effect of the font is one that is not very easy or pleasurable to read for longer text pieces, in fact making it a font that is more suited for the needs of the computer than that of easy human readability.

But here the logic goes towards enabling the computer to fast and easy make the distinction between a capital “o” and a zero, without doing what we as humans of cause easily do – which understanding which is meant due to the context in which it’s presented. One could for example mention the very weird captital “o” among other odly shaped characters. Thus enabling printed matter to be translated into digital form without having to have a person manually type in the information once again.ĭue to the in today’s view limited ability of text recognition by computers, the outcome was a quite peculiar looking typeface.

Tracing the development of digitization of text the invention of text recognition software, also known as OCR (optical character recognition), might be said to have played a key role in the transition period to the above mentioned development.Ĭommissioned in 1968 by the American National Standards Institute the font OCR-A was released, as a international standard for a font easily read by humans and computer. However we don’t have to travel very far back in time to find a different reality. Text in it’s digital form or as a product of a digital process prior to printing is what we mainly encounter today.
