Claim Text:
1. A method of determining user input in a 3D field relative to a 2D surface, the method comprising: defining an inner perimeter; defining an outer perimeter; defining a lower perimeter; defining an upper perimeter; defining a first side perimeter; defining a second side perimeter; wherein said inner perimeter intersects said lower perimeter, said upper perimeter, said first side perimeter, and said second side perimeter; wherein said outer perimeter intersects said lower perimeter, said upper perimeter, said first side perimeter, and said second side perimeter; wherein said upper perimeter intersects said inner perimeter, said outer perimeter, said first side perimeter, and said second side perimeter; wherein said lower perimeter intersects said inner perimeter, said outer perimeter, said first side perimeter, and said second side perimeter; wherein said first side perimeter intersects said inner perimeter, said outer perimeter, said upper perimeter, and said lower perimeter; wherein said second side perimeter intersects said inner perimeter, said outer perimeter, said upper perimeter, and said lower perimeter; wherein said upper perimeter, lower perimeter, inner perimeter, outer perimeter, first side perimeter, and second side perimeter define a 3-dimensional detection field; detecting one or more user input objects in said 3-dimensional detection field relative to a 2-dimensional surface; determining 3-dimensional coordinates for the one or more user input objects within said 3-dimensional detection field relative to the 2-dimensional surface; determining a touch user input based on the coordinates; determining a touchless user input based on a second set of 3-dimensional coordinates within said 3-dimensional field associated with the one or more user input objects.
