That is why Tactus, a company based in California, has developed technology which can turn a typical flat tablet screen into a real keyboard with bumpy buttons.
The keyboard rises from the tablet when needed, before disappearing when the typing is done.
Micah Yairi from Tactus explained how it works.
i think this is cool. i kinda want that one now. i've never been a huge fan of typing with a screen.
