1. A tactile interface comprising:

  • a tensioned elastomeric material;

    a plurality of individually controllable drivers positioned around the perimeter of the tensioned elastomeric material; and

    driver circuitry coupled to each of the plurality of individually controllable drivers, the driver circuitry configured to receive control information for selected ones of the plurality of individually controllable drivers, and to produce a standing wave pattern in the elastomeric material by electrically modulating a subset of the plurality of individually controllable drivers at frequencies different from a steady state oscillation frequency or a harmonic of the steady state oscillation frequency.
