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.
