CES 2013: The tablet that turns itself lumpy

10 January 2013 Last updated at 05:50 ET Help

When you can't feel individual keys on a touchscreen device it can be hard to type at speed.

The keyboard rises from the tablet when needed, before disappearing when the typing is done.

Micah Yairi from Tactus explained how it works.
