Claim 3:
4. The input device as claimed in claim 1, wherein each of the matrix of analog push button assemblies comprises an analog pressure sensor, wherein the analog pressure sensor comprises:
a pressure reception arrangement having an optical sensing sub-arrangement configured to measure an amount of light varied according to a pressure sensed at the pressure reception arrangement and an output terminal, and
a plunger element configured to exert the pressure on the pressure reception arrangement, wherein when the at least one of the matrix of analog push button assemblies is pressed by a user's finger, the amount of depression of the at least one of the matrix of analog push button assemblies causes the plunger element of the at least one of the matrix of analog push button assemblies to correspondingly exert the pressure on the pressure reception arrangement of the at least one of the matrix of analog push button assemblies to vary the amount of light to be detected by the optical sensing sub-arrangement so as to generate the analog signal corresponding to the amount of depression of the at least one of the matrix of analog push button assemblies.
