Claim One:
1. A method comprising: i) a mid-air haptic feedback system producing an acoustic field from a transducer array having known relative positions and orientations; ii) the mid-air haptic feedback system defining a plurality of control points wherein each of the plurality of control points has a known spatial relationship relative to the transducer array and has a control point activation coefficient; iii) the mid-air haptic feedback system calculating a complex wave field sample matrix at a plurality of control point positions of a first index; iv) the mid-air haptic feedback system actuating at control point positions of a second index preset amplitude and zero phase offset control points; v) the mid-air haptic feedback system calculating an eigenvector based on the complex wave field sample matrix; and vi) the mid-air haptic feedback system adjusting the eigenvector to represent a plurality of control point activation coefficients.
