1. A user interface system comprising:

  • a tactile sensor array,an arrangement for scanning the tactile sensor array, the scan producing a corresponding array of measurement values;

    a processor for calculating of a plurality of running sums from selected measurement values or functions of selected measurement values;

    a post-scan computation algorithm for deriving at least three independently-adjustable interactive control parameters responsive to at least displacements or angles the contact of a single area of threshold contact or threshold proximity; and

    an algorithmic element for handling of regions of threshold contact or threshold proximity having non-convex shapes,wherein the system provides output control signals, the control signals responsive to the independently-adjustable interactive control parameters.
