       Standard QWERTY results in tiny buttons that are too small for most fingers and thumbs. Elegant mobile-QWERTY button layout results in larger buttons, fast typing, and fewer typing errors.



Current mobile phone keypads are compromises, turning-off many users - why?

Some keypads have more than one letter per button, making them unpredictable and complex to operate. 

Others use QWERTY, which was not intended for single-hand operation phones. QWERTY's 10-button wide footprint is too wide for hand and finger geometry, trading-off cramped buttons with uncomfortably wide phones and forced two-handed operation.

Finally, keypads with button layouts unrelated to QWERTY (e.g. ABCDE) require months of practice to reprogram our QWERTY motor memory reflexes.

The result - service providers lose billions of dollars every year in profitable wireless data revenue. However...

Delta II is consumer-tested from its inception as a high-performance keypad for modern mobile phones.




Mobile Phone Keypad

Alphabetical Keypad

Delta II Keypad

Good for entering numbers, bad for entering text.

This number-centric keypad was not designed for rapid text entry and requires too much thinking, pausing, and button pushing to enter text quickly.

Typing text on this keypad is so tedious that most people won't use it to store names and numbers in their cell phones, much less to type an email.

Even with disambiguation algorithms, 10-15 WPM are typical typing speeds on this keypad.



Surprisingly, typing on a simple, 26+ button alphabetically ordered keypad is a painfully slow and punishing experience.  

We often "stall" when looking for the next letter we want to type.

That's because alphabetic layouts are totally different than the PC keyboard (QWERTY) layout we have spent so many hours using.

When typing on an alphabetically ordered keypad, a reflex called motor memory causes us to constantly look for letters in the wrong places.

For instance, we are used to seeing and reaching for the letter "Q" in the upper-left corner of our keyboard, but on any alphabetically ordered keypad, the letter "Q" is somewhere near the bottom.

It's like trying to write your name upside-down.

Even after hours of practice, don't expect to type much faster than 15-20 WPM on alphabetically ordered keypads.

On a Delta II keypad, you fly.

Now the letter "Q" is where you expect it to be.

The Delta II speed matrix immediately boosts your typing speed three to four times faster than a cell phone keypad and twice as fast as 26+ button alphabetically ordered keypads.

That's 20 to 30+ WPM typing speeds - straight out of the box.

This is possible because letters on Delta II keypads are located in proximity to their original locations on your PC keyboard.

Delta II combines your PC keyboard experience and motor memory reflexes to your advantage.

Within minutes, you are cruising, typing even faster.

Your mind is quickly completing the connection between your PC keyboard and the Delta II keypad.

What a huge difference the right layout makes.

Now there is no doubt, no contest:

You are typing on the most desirable mobile phone keypad in the world.
