iPad 3 Texture Touch Screen?

Could Apple CEO Tim Cook unveil a textured touch screen iPad 3 tonight at the eagerly awaited Apple launch event?

A Senseg E-Sense touchscreen with texture is the latest rumour in the mill.

The "haptic" display that gives the sensation of texture when the screen is touched has captured the imagination of Apple rumour merchants.

Swiss EPFL researchers developed the technology that gives a braille-like experience to tablets and touch screens.

The screen flexes at the micron level, shooting the perception of texture to the user's fingers.

As with all Apple rumours, the company and its suppliers remain tightlipped.

The Guardian asked Petri Jehkonen, Senseg's technical marketing manager, whether Apple is not a customer. He said: "That would be for Apple to say. My comment is no comment."
