1. A user interface method, the method comprising:

  • obtaining a projector display of an initial image;

    using one or more sensors coupled to a computer processor, sensing a user interaction with the displayed initial image, the user interaction being in a three dimensional coordinate system, and said sensing being based on quadrilateral angle navigation that determines a sensing point position within the three dimensional coordinate system, wherein an original image is displayed from a certain point in space preconfigured to match specific points in the quadrilateral angle navigation, and the certain point in space is matched to space location of the user interaction to determine the sensing point, said sensing resulting in each sensor providing coordinate information to the computer processor enabling the computer processor to correlate with the original image in the three dimensional coordinate system;

    in the computer processor, correlating the sensed user interaction with the three dimensional coordinate system and responsively manipulating the initial image resulting in an updated image based on the correlated user interaction; and

    from the computer processor through a projector, projecting the resulting updated image, the updated image being equivalent to the initial image manipulated by a distortion in three dimensional space.
