Zusammenfassung:	A method, apparatus and system of projecting text characters onto a textured document are described. The method comprises determining, from a captured image of the textured surface, a measure of the texture on the surface for a region of the textured surface over which the text characters are to be projected; selecting, based on a function of the determined measure, a glyph set, each glyph in the glyph set having visually contrasting inner and outer portions, the outer portion being sized proportionally to the inner portion according to the determined measure; and projecting the text characters onto the textured surface on of region using the selected glyph set.
