A method and system for presenting data on a medium for capture by an
input device is described. The method embeds a symbol design, such as an
embedded interaction code (EIC), in an image on a display screen, such as
a liquid crystal display (LCD). A grid with a plurality of pixels defines
a size of an EIC pattern on an LCD. An area of the grid is used to embed
position data and/or metadata information. The area may be defined by a
sub-pixel of the plurality of pixels and/or the edges of the grid itself.
The sub-pixel with the EIC pattern may be configured to have a grey value
based upon a color of an underlying image associated with an application
program being displayed on the LCD. The method also allows for decoding
of the position data and/or metadata information in the EIC pattern on
the LCD.
