Method and apparatus for automotive variable impedance touch sensor array

An interface system, comprising:

• an interpolated variable impedance array comprising a group of controls and a grid of sensing elements configured to generate multiple currents along multiple current paths based on detection of a touch input at a control of the group of controls, wherein the group of controls comprise haptic feedback devices and the interpolated variable impedance array is associated with a vehicle and the touch input is received from a driver of the vehicle;
• and
• an analog-to-digital converter and a processor communicatively coupled to the interpolated variable impedance array and configured to determine information related to the touch input based on the multiple currents along the multiple current paths,
• wherein, based on the information related to the touch input and continuous pressure patterns associated with the touch input, the processor;
• selectively outputs a safety measure to the driver, and
• determines a force profile that defines a type and amount of feedback output in response to the touch input.
