Disclosed is an interactive educational apparatus, ideally suitable for
children. A set of symbol pieces, preferably in the form of letter blocks
are provided. An interface board is provided for accommodating one or
more selected symbol pieces and a sensor on said interface board
generates a signal identifying each symbol piece when placed on said
interface board. Media files are stored on a storage medium and each
media file has an associated tag. A processor is programmed to match a
search key represented by one or more selected symbol pieces with said
tags. A display device displays one or more media files having identifier
tags matching said search key represented by said selected symbol pieces.
These identifier tags provide a means to match up the media files with
each search key generated by placement of the symbol pieces on the
interface board.
