1. A sports device comprising:

  • one or more cameras for recording video frame data used to characterize a trajectory of a sports object launched by a person wherein the person is attempting to reproduce a particular trajectory of the sports object and wherein one or more trajectory parameters characteristic of the particular trajectory are derived from a curve-fit of the particular trajectory;

    a logic device configured to i) receive selections indicating a plurality of different virtual target areas;

    ii) receive the video frame data, iii) recognize the sports object in the video frame data;

    iv) determine a curve-fit for the trajectory of the sports object captured in the video frame data;

    v) determine where the curve-fit for the trajectory of the sports object captured in the video frame data passes through one of the plurality of different virtual target areas;

    vi) determine one or more trajectory parameters that are derived from the curve-fit of the trajectory of the sports object and vii) based upon the one or more trajectory parameters derived from the curve-fit of the trajectory of the sports object, generate immediate feedback information that allows the person to evaluate their skill at reproducing the particular trajectory.
