VIDEO: 4iThumbs tactile keyboard for iPhone launches

4iThumbs appears to be designed for iPhone users that can't get on with the touchscreen, but don't want to give up their precious.

It's a clear, tactile typing aid for the iPhone's screen that "facilitates faster and more accurate typing, enables blind typing, reduces glare and is the strongest screen protector on the market".

The tactile ridges are said to "guide thumbs for accurate input to ease the transition from other smartphones to the iPhone", so a little like stabilisers, we guess.

4iThumbs is priced at $14.95 for the portrait version, $16.95 for the landscape version and $19.95 for both. Hit the video above for a "spoof" ad.
