Pen that checks for spelling error invented

Okay, so Where would some of us be without spell check?

The sometimes annoying, but frankly indispensable computer aid has spared billions of typographical blushes..you doubt ?

Now, an ingenious prototype pen developed by a German start-up is promising to give our longhand writing a similar sort of safety net.
Lernstift (German for "learning pen" is a digital pen with a difference, carrying not only ink inside its casing but also a tiny computer that alerts users to spelling errors.

Daniel Kaesmacher, co-founder of Lernstift said: "Basically there are two functions. The calligraphy mode which helps you correct individual letters, and the orthography mode which vibrates when a word is misspelled."
