More and more people are including a disclaimer in their emails that excuses them from typos. They claim they have fat fingers and it is impossible for them to type without many mistakes.
I am happy to announce to all my fat-fingered friends that a new type of keyboard is under development that will give you the feel of a typewriter without the tap, tap, tap that used to drive us all crazy. It is being designed for smartphones and tablets.
The keyboard appears when you need it and disappears when you’re done. It rises from the touch screen and becomes a keyboard of bubbles.
Silicon Valley start-up Tactics Technology, of Fremont, CA, said it is using microfluidics to make physical keys bubble up from the surface of a touch screen when you need to type and disappear, when you don’t.
Microfluidics are used in an inkjet printer so the technology is not that foreign to you.
A full explanation of how it works is explained here.

My nails are very happy with this development. I still don’t have a smart phone or a pad, but when one gets handed to me, I find navigation challenging. The problem is not dragon claws, just a square set of pink and whites being manipulated by a klutz.
