Touchscreen phones and tablets are wonderful devices. But touchscreen typing is cumbersome compared to a traditional keyboard. Worry not, though: some clever souls have invented a workaround:
Tactus provides a new dimension to touchscreens by enabling real, physical buttons that rise up from the surface on demand, and then recede back into the screen, leaving a perfectly flat, transparent surface when gone.
Cool.
Inertia Wins!
