Abstract
Electrostatic friction textures on a touchscreen panel are used to create the sensation of braille text 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 to the passenger in Braille form or a completely different set of information and menu structure in Braille form. The manner of providing a Braille display in an automobile is adapted for vehicle vibration and movement, the types of functions normally presented and/or controlled by passengers, and other challenges Braille readers of different ages, health, or experience may face when attempting to read Braille in a vehicle cabin.
