A method of identifying a surface and a sticker on the surface, the sticker including a first region having disposed therein or thereon first coded data at least partially indicative of a sticker identity, and a second region, the surface having disposed therein or thereon second coded data at least partially indicative of an identity of the surface and a plurality of locations on the surface, the method including, in a computer system: receiving indicating data from a sensing device, the indicating data being at least partially indicative of the identity of the sticker, the identity of the surface and a position of the sticker on the surface, the sensing device, when placed or moved in an operative position relative to the sticker, being responsive to sense at least some of the first coded data and sense, through the second region, at least some of the second coded data and generate the indicating data using the sensed first coded data and the sensed second coded data; and, identifying, using the indicating data, the identity of the sticker, the identity of the surface and the position of the sticker.
