Abstract
Electrostatic friction textures on a touchscreen panel are used to create the sensation of block icons in a contextual menu adapted to an automotive environment. In particular, a center stack touchscreen friction display in a passenger vehicle provides one set of touch controls and HMI data to the driver while simultaneously providing either the same control options and HMI or a completely different set of information and menu structure to the passenger in invisible texture form. The invisible texture is in the form of block icons, and coincidence between a finger of a passenger and a block icon results in an audio announcement of the block icon to guide a visually impaired passenger through the contextual menu.
