1. An apparatus comprising:

  • a capacitive sensor;

    a button comprising a first material having a first dielectric constant, the first material comprising;

    a distal coupling portion distal from the capacitive sensor and configured to capacitively couple with an object; and

    a proximal coupling portion proximal to the capacitive sensor and configured to capacitively couple with the capacitive sensor;

    a support connected to the button and configured to deflect when the button is pressed to allow the button to move closer to the capacitive sensor; and

    a controller connected to the capacitive sensor and configured to measure a value associated with an amount of capacitive coupling between the button and the capacitive sensor, the amount of capacitive coupling between the button and the capacitive sensor based at least on the following;

    an amount of capacitive coupling between the distal coupling portion and the object; and

    a distance between the proximal coupling portion and the capacitive sensor.
