Abstract
A tiled interactive screen comprises a mounting surface and tiles mounted on the mounting surface. Each tile comprises a tile substrate with photoluminescent marks disposed in a pattern on or in the tile substrate. Each photoluminescent mark is unique with respect to every other photoluminescent mark on any of the tiles, each photoluminescent mark comprises a pattern encoding information specifying the location of the photoluminescent mark on the tile, and each tile substrate is at least partially transparent to light absorbed by the photoluminescent marks and is at least partially transparent to light emitted by the photoluminescent marks. The photoluminescent marks respond to stimulating electromagnetic radiation by emitting electromagnetic radiation. A tiled photonic interactive system comprises a tiled photonic interactive screen and an optical stylus operable to emit stimulating radiation onto one or more photoluminescent marks and respond to electromagnetic radiation emitted by the stimulated photoluminescent marks.
