System and method for capacitive split contactless keyboard stack with capacitive encoding to identify among a plurality of removable tactile input layers

Abstract

An information handling system having a split keyboard structure with a keyboard sensing hardware structure formed under a sealed input surface with a hardware processor, a data storage device, and a power management unit formed into a keyboard chassis. The keyboard sensing hardware structure includes capacitive pad sensors operably coupled to a capacitive sensor microprocessor to detect capacitive changes from user interaction with one of a plurality of removable tactile input layers installed above the sealed input surface. The capacitive sensor microprocessor executes machine readable code instructions of a dynamic key mapping engine to detect, via the capacitive pad sensors, capacitive encoding for determining a first removable tactile input layer that is installed from among the plurality of removable tactile input layers via detection of cumulative capacitance or a first set of conductive material portions formed with a plurality of keyboard keys having a unique layout, number, or arrangement.
