FIELD: information processing.
SUBSTANCE: invention relates to data input apparatus and, in particular, is designed for an underwater information input and display apparatus. Data input apparatus for an electromagnetic resonance-based information input and display apparatus isolated from the environment comprises a body, placed in the body whereof is an oscillatory circuit set in resonance with an inductive sensor node of the information input and display apparatus, wherein the body isolates the oscillatory circuit from the environment, and the front of the body is made flexible, configured to transmit mechanical impact from the front of the body to elements of the oscillatory circuit in order to change the resonant frequency.
EFFECT: possibility of using a data input apparatus operating on the basis of electromagnetic resonance in extreme conditions, e.g., underwater.
