Bridging the digital divide

1 Reply George Guest

In this day and age, people have come to expect at least a modest speed for their internet connection. In many urban parts of the UK, speeds of around 10MB per second are commonplace, with some homes experiencing five times that amount. Home internet access has become a prerequisite for many school pupils in their learning, but not all of them are so lucky.

For many children based in rural areas or internet blackspots or for those whose families cannot afford to pay a premium for access, getting the information they need in order to complete their homework or simply boost their knowledge is extremely challenging. This is something that was raised by Estyn, the Welsh education watchdog, and they’re not alone.

Call for more investment

Those in rural areas, even if they’re just on the edge of major conurbations such as Greater Manchester and Leeds/Bradford, will find getting even basic broadband a pain, which has seen people in high-powered positions call for investment in improving connectivity where there is none. David Nuttall, the MP for Bury North in Greater Manchester, is one such voice.

Of the £990,000 allocated to the region, Mr Nuttall is calling for a large chunk of that to go towards people in his constituency who are experiencing problems with their speeds and, in extreme cases, access.

“Those who live in areas which have very slow broadband access speeds are seriously disadvantaged in this digital age”, he said in an interview with the Bury Times.

“Although in recent months we have seen some progress — for example in Nangreaves thanks to the hard work of local residents — there is still much to be done”, he added.

Solution from above

An optical fibre broadband cable

Whilst fibre optic broadband the fastest form of broadband, satellite broadband offers much faster speeds for those in rural communities, without optical fibre cables.

Until something is done about access to fast broadband nationwide, those affected are left to ponder what, if any, alternatives are open to them. One could come in the form of satellite broadband, which can work as more than just a stopgap solution.

“Many people don’t realise the role satellite broadband has in filling in rural not-spots and connecting the last 5% of homes and businesses that will never get fast broadband over wires”, said Andrew Walwyn, CEO of EuropaSat.

“The latest generation Ka band satellite broadband services offer defined, predictable service levels at reasonable cost, with no geographical discrimination. Using a small set-top box and an outside mini dish it’s now possible to deliver up to 20 Mb fast broadband to any property in the UK or indeed Europe.”

I was an English teacher for many years in Italy, and every year I played a game with the students. In groups we had an hour to invent an incredible product, prepare publicity for it and act it out to the class.

I had a can of Happiness and the logo “Happiness, now available in cans”. Many of the inventions revolved around making your school life easier though, including the intelligent pen that could for example write the correct answers in the test or translate from one language to another.

Well girls from Liceo Secco Suardo your dreams have come true. You in fact saw the future. Roll out the Smartpen.

 

Learnstift's Smartpen

Learnstift’s Smartpen

The Learnstift Smartpen checks your spelling as you write. Incredible but true. Learnstift is a German Start up, and they are about to release their incredible product in English and German. It has 2 functions, one to help you write better that recognizes the form and shape of individual letters, and one that checks the spelling.

The pen has a tiny Linux computer inside that runs off a battery. It is fitted with a non optical motion sensor and a vibrating mechanism, so it can recognize the word you have written and if it is spelt wrong it will vibrate so you can try again.

It has wi-fi so you can connect to your phone or other hardware, and with a launch price of between $150 to $200 it is cheaper that paying me to come round to correct your homework.

Joking apart the producers hope the pen will become a valuable learning tool and of particular interest to dyslexic children. Although initially only in German and English as the project takes off more languages will be introduced.

Any of you who have learned a new language will understand how such a tool could be used in language learning and business communication, and as the pen can be made in ball point, fountain and even pencil versions I think there might be a fuchsia for it.

Fighting spam and recapturing books with reCAPTCHA

2 Replies Christopher Roberts

A CAPTCHA is an anti-spam test used to work out whether a request has been made by a human, or a spambot. CAPTCHAs no longer seem to be as popular as they once were, as other spam identification techniques have emerged, however a considerable number of websites still use them.

CAPTCHA pictures

Some common examples of CAPTCHAs.

CAPTCHAs can be really annoying, hence their downfall in recent years. Take a look at the different CAPTCHAs in the image above, if you had spent 30 seconds filling in a feedback form, would you be willing to try and decipher one of the above CAPTCHAs, or would you just abandon the feedback?

The top left image could be ZYPEB, however it could just as easily be 2tPF8. If you get it wrong, usually you will be forced to do another, which could be just as difficult.

The BBC recently reported how The National Federation for the Blind has criticised CAPTCHAs, due to their restrictive nature for the visually impaired. Many CAPTCHAs do offer an auditory version, however if you check out the BBC article (which has an example of an auditory CAPTCHA), you will see that they are near impossible to understand.

reCAPTCHA

Luis von Ahn is a computer scientist who was instrumental in developing the CAPTCHA back in the late 90’s and early 2000’s. According to an article the Canadian magazine The Walrus, when CAPTCHAs started to become popular, Luis von Ahn “realized that he had unwittingly created a system that was frittering away, in ten-second increments, millions of hours of a most precious resource: human brain cycles.”

Anti-spam reCAPTCHA

An example of a reCAPTCHA CAPTCHA.

In order to try and ensure that this time was not wasted, von Ahn set about developing a way to better utilise this time; it was at this point that reCAPTCHA was born.

reCAPTCHA is different to most CAPTCHAs because it uses two words. One word is generated by a computer, whilst the other is taken from an old book, journal, or newspaper article.

Recapturing Literature

As I mentioned, reCAPTCHA shows you two words. One of the images is to prevent spam, and confirm the accuracy of your reading; you must get this one right, or you will be presented with another. The other image is designed to help piece together text from old literature, so that books, newspapers and journals can be digitised.

reCAPTCHA presents the same word to a variety of users and then uses the average response to work out what the word actually says – this helps to stop abuse. In a 2007 quality test, using a standard computer text reader, (also known as OCR) 83.5% of words were identified correctly – a reasonably high amount – however the accuracy of human interpretation via reCAPTCHA was an astonishing 99.1%!

According to an entry in the journal Science, in 2007 reCAPTCHA was present on over 40,000 websites, and users had interpreted over 440 million words! Google claim that today around 200 million CAPTCHAs are solved each day.

If each CAPTCHA took 10 seconds to solve, that would have been around 139 years (or 4.4 billion seconds) of brain time wasted; I am starting to see what Mr von Ahn meant! To put the 440 million words into perspective, the complete works of Shakespeare is around 900,000 words – or 0.9 million.

Whilst the progress of reCAPTCHA seems pretty impressive, it is a tiny step on the path to total digitisation. According to this BBC article, at the time von Ahn is quoted saying:

“There’s still about 100 million books to be digitised, which at the current rate will take us about 400 years to complete”

Google

In 2009 Google acquired reCAPTCHA. The search giant claimed that it wanted to “teach computers to read” hence the acquisition.

Many speculate that Google‘s ultimate aim is to index the world, and reCAPTCHA will help it to accelerate this process. That said, if that is its goal, it is still a very long way off.

We won’t be implementing a CAPTCHA on Technology Bloggers any time soon, however next time you have to fill one in, do spare a thought for the [free] work you might be doing for literature, for history and for Google.
