ASSOCIATING A REGION ON A SURFACE WITH A SOUND OR WITH ANOTHER REGION

摘要

A surface that includes a pattern of markings that define spatial coordinates on the surface is scanned. The pattern of markings is decoded to define a region on the surface. Additional information is associated with the region. For example, a sound may be associated with the region such that, when the region is subsequently scanned, the sound may be audible. In another example, a second region on the same or on a different surface may be associated with the first region.
