1. Apparatus for providing user operational impulse inputs for directing a connected electronic device comprising:

  • an external enclosure provided with at least one substantially-planar, moveable, input surface defined by bounding edges;

    the location of any point on said input surface being designated by an orthogonal coordinate system, the origin of which is fixed adjacent the intersection of a pair of said bounding edges while the x and y basis vectors of which are aligned parallel to at least one of said bounding edges and the z basis vector extends substantially perpendicular to said input surface;

    said at least one input surface being mathematically mapped into a group of one or more n-sided closed polygons, each said polygon defined by the length of an side and the x abscissa and y ordinate coordinates of its centroid of area;

    each said polygon representing a particular input character or logic value by which the user enters operational commands for directing said connected device;

    an array of multiple motion sensors each mechanically linked to said input surface and adapted to provide signals directly reflective of impulse-vector-related displacements thereof consisting essentially of;

    free-body displacement, rotation about an axis drawn across said input surface and transient elastic Chladni deflections of said input surface;

    said sensor array being sufficiently sensitive for accurately detecting changes;

    in the vector velocity of said origin, in the angular velocity of one or more said bounding edges about said axis and transient flexural deflections of said input surface in the frequency range below about 10 000 Hz;

    each said polygon being initially pre-configured by user'"'"'s application of a standardized impulse of mechanical energy indicative of a specific operational input, said impulse being;

    oriented, in spherical coordinates with degree units, in a predetermined vector direction, (1,1a) and (1,1b), and sustained for a predetermined force*time interval, in N-sec units, (1,1c);

    a processor supported adjacent said array and connected to receive said operational displacement signals;

    said processor adapted to store and access said user-configuration signals as individual records in a (CVP) configuration database;

    said processor adapted to discriminate technical features of accidental movements of said surface and to reject invalid operational impulses thereupon including;

    accidental user impacts and body tremors, environmentally-coupled acoustic vibrations, unintended ultrasonic-frequency-wave reflections-dispersions as well as Lamb- and surface-acoustic waves;

    said processor, during post-configuration operation, being especially adapted to utilize stored solution algorithms for producing exceptionally accurate, immediate technical effects including dynamic analysis of accelerations resulting from each operational impulse and generation of an instantaneous-operational (CVP) parameter;

    said technical effects also including;

    (a) filtering-conditioning for removal of noise and interfering signals, (b) threshold testing, (c) vibration profile characterization, (d) input site determination and finally (e) impulse focus and intensity characterization and (f) comparison of instantaneous (CVP) parameters with said configuration database, whereby the polygon with the nearest (CVP) match is reliably identified;

    whereby said processor is adapted to deliver an output pulse into the connected device reflective of the intent of the user'"'"'s operational impulse.
