1. An analog input device comprising:
at least one mounting panel;
a matrix of analog push button assemblies mounted to the at least one mounting panel, wherein each analog push button assembly outputs an analog signal as a measure of an amount of depression of said analog push button assembly when pressed by a user's finger;
a multiplexer including an input side and an output side, wherein the input side is coupled to output terminals of the matrix of analog push button assemblies;
an analog-to-digital converter which is coupled to the output side of the multiplexer, wherein the analog-to-digital converter converts the analog signal from a corresponding push button assembly pressed by the user's finger into a digital-step-value; and
a processor which is coupled to the analog-to-digital converter and which is configured to output a data packet including a button identity (ID) of the corresponding push button assembly pressed by the user's finger and the digital-step-value converted from the analog signal of the corresponding push button assembly by the analog-to-digital converter, the data packet being for transmitting to a host computing device.
