Where the phark is my shea enhancement?

As part of the developments taking place at the BBC, the team have been looking at different spin on image replacement techniques. Why the phark should I care? Because it will add extra value for screen reader users.

Usually, image replacement is applied to headings. Designers use images to make headings look cool, but they also have plain text effectively hidden behind it so that none of the usefulness of a heading or text is lost. We looked at the Conservative party’s sort-it website recently that uses this technique. Sighted viewers are treated to headings set at jaunty angles, yet screen reader users can still use their hotkeys to jump between them. Phark and shea are two different coding techniques for doing this.

The BBC have been looking to use this for something else though. In the TV schedules being designed, space is at a premium. There’s a lot of information to pack in for all those programmes after all. For sighted users, a picture can tell a thousand words, so only a short piece of text is required. As these visual clues are not available to screen reader users, and alt text considered inappropriate for this purpose, another approach is needed to provide the extra detail needed. The solution? Using the techniques developed for image replacement.

During experimentation, the BBC are currently favouring the shea enhancement technique over pharking. Whilst there are good technical reasons for this, we can’t help feeling a little disappointed. Pharking is a wonderful verb, that could lend itself to being utilised on t-shirts every geek would be proud to wear. Sadly shea-ing just doesn’t cut it as a verb or a t-shirt. As one BBC insider confided, “It sounds like some kind of space age transgender plastic surgery.” So look out for sheaing on the BBC schedules and the next series of Torchwood.

I watched the last episode of torchwood,and was very intregued as to what took Jack from the hub. I have also heard that The Rani will be back, or maybe The Master (in the new series of Doctor Who) If you remember Jack said the 'the right sort of doctor' would of made him open the rift, therefor i purpose that it was not infact the Doctor that took Jack but infact The Rani or The Master. There Tardis can change so it could of changed to look like The Doctors Tardis. The face of Boe is also due to appear,and is apparently to say five words to the Doctor;You're not the only one, this could be the cliff hanger in series three of Doctor Who as we have also had Russel T. Davis saying Jack will be in the last episode.I also wish to state that i have just turned 14.
