However i have finally got around to writing something again so here you go, enjoy!
I came across an interesting product/concept for those that love their touch screens, in particular tablets etc bigger than phone size, but who find typing on them to be an issue. the solution from Tactile a company in the US is that of one where the keyboard suddenly appears out of the flat surface of the touch screen itself! At first i thought it was a joke or some hideous kind of add on/overlay, however it is actually a nice looking (albeit slightly creepy) idea/product. At the touch of your finger the keys just suddenly appear before your eyes and finger tips.
How can this be done you ask? Well it is done using a see through liquid layer applied to the surface of the touch screen which is pumped through channels to make the keys appear as if by magic. There are multiple settings for firmness of the keys from slightly squishy bubbles to much more solid "proper" button feel. i am unsure whether it is the case that it will always rise even when you don't need it or not but we shall see if it ever becomes main stream i guess. The company currently only has one partnership to implement this technology and it is with Touch Revolution, who make touch screens. Nosh, Signing Out.
