function getNonBallDeltas
% note:     In the standard position of the device mouse A is on the east side, mouse B on the north side
%
%       According to the MouseBall Tracker application:
%       ax goes positive if the ball turns away from mouse A, and negative if the ball turns towards Mouse A
%       bx goes positive if the ball moves away from mouse B and negative if the ball moves towards mouse B
%
%       ay goes positive for counterclockwise and negative for clockwise rotation
%       by behaves in the same way
%
%       mouse walks north: bx goes positive
%       mouse walks south: bx goes negative
%       mouse walks east:  ax goes positive
%       mouse walks west:  ax goes negative
