Retrieval of information within a large amount of
multimedia data can be overwhelming.
Professionals who work daily with huge digital li-
braries (i.e. broadcast editorial staff) require ef-
ficient and ease to use interfaces to search, visu-
alize and organize video results collected in their
Users can browse concepts from an ontology
structure in order to select keywords and start
the video retrieval process.
The system exploits the search engine Sirio for
the retrieval and the semantic reasoning on mul-
The architecture consists of an infrared LED array
as an overlay built on top of an LCD screen. The
multi-touch overlay detects objects on its surface
and sends information using the TUIO protocol.
An input manager layer connects a socket server
to a gesture framework and a core logic, in or-

Videos can be placed out of the list and moved
along the screen, resized or played. A cluster of
videos can be created by collecting two or more
