Disclosed is a mechanism for biasing cursor movement to follow the edges of 'fuzzy' graphical objects (such as photographs). This permits fast cursor movement along an edge, with fine control orthogonal to the edge. The effect is automatically modulated by edge strength; cursor movement is unbiased where the cursor is not near any edge. The disclosure is in two parts. The first describes the general principle and the second gives a fragments of sample code for more precise detail.
