Claim 0:
1. An apparatus, comprising:
a switchable glass structure supported within a vehicle and comprised of a plurality of layers;
a power source that is selectively applied to the switchable glass structure to change the switchable glass structure from opaque to clear;
markings formed within at least one of the plurality of layers to identify user input areas; and
a control system that includes a circuit configured to cooperate with the power source to allow the switchable glass structure to act as a capacitive sensor such that user input to the user input areas is able to change the switchable glass structure between opaque and clear modes, and wherein a signal is generated by the control system to control the switchable glass structure in response to user input to the user input areas, and wherein the control system is configured to make a capacitive measurement when the signal goes to zero to determine if a user is interacting with the user input areas.
