Abstract:
In this paper, an artificial human interface based
on magnetic resonance coupling is proposed to detect and sense
the direction of movement of a fingertip. The finger movement
is analyzed by recognizing the change in magnetic coupling
observed between a static transmitter coil and a static receiver
coil array due to presence of a small coil resonator placed at the
fingertip. By measuring induce voltage responses in the spatially
distributed receiver coil array, the movement of the resonator
coil is characterized. A commercial software Ansys EM suite 19.1
is utilized to demonstrate applicability of the proposed design.
The fingertip movement is examined by moving the resonator
in various directions and the observed results corroborate the
claims. Therefore, the proposed touchless pad is found well
suitable for infection free accessibility of the computer systems.
