Going through patent application and refinement could take well into 2013 for Synaptics but their ThinTouch keyboard technology could help shave more from the thickness of an Ultrabook.

Video below.

Current Ultrabook keyboards are still based on the ‘scissor’ action mechanics that have been around for years but those keyboard below 3.5mm in thickness is proving to be a challenge.

ThinTouch has a key travel of 0.75 mm vertically but includes a horizontal movement too. Total keyboard thickness is 2.5mm which could enable a 12mm thin Ultrabook design.
