KALQ is gonna outdate QWERTY?

Hai buddies,

 You must be familiar with the term QWERTY. But you ever heard about KALQ?

Simply speaking, KALQ is a new split screen keyboard designed to speed up thumb typing on tablets and large smart phones.

 In this post am gonna say a few words about what is KALQ, why it s needed and a small comparison between QWERTY and KALQ.

Here we go.!

As Alexander the great said ,touchscreen tablets also came ,saw, conquered our hearts. It taught our thumbs to pinch and swipe, slide and scroll. Yes, we are pretty habituated. But still texting through touch screen is sometimes not handy.
I think many will agree with this statement.

Heard  a good news that  Researchers at the University of St Andrews have developed a split-screen keyboard, specifically optimized for thumbs, which they claim can increase typing speeds by more than a third.its KALQ.

Why the name KALQ?

New keyboard KALQ got its name from the letters at the bottom right of the keyboard.

What is new in KALQ?

Keys in two Blocks:
Designed to save your thumbs stretching across the screen and making repeated taps, Kalq splits the keys into two blocks, 16 to the left, 12 to the right. Commonly used letters are clustered together and frequent pairs of letters placed on alternate sides, so each hand does the same amount of work.'

Researchers say "Tests show that after only 10 hours of training, users were able to reach 37 words a minute, compared with the average of 20 words a minute on a qwerty device..!!"


Did you know?

The  mechanism of typewrite, the pioneer,  staggered letters diagonally across the keyboard, rather than arranged in a rectilinear grid, to prevent the levers from running into one another.Qwerty followed the same just for purely mechanical considerations, yet it has endured until today and been unquestioningly translated into the touchscreen arena.

Will Kalq finally have what it takes to revolutionize typing in our increasingly thumbs-only world?? 
Time will give the answer.
Wait n C..!!
