   4. Technical discussions
The gesture recognition system:

      NT, GD, MH and DC fixed the agreed set of gestures. GSA-DDS will send a summary of set of
       gestures to HOL. MH will create a revision of D11 that will contain the agreed set of gestures.
      GSA-DDS confirmed that the first release of D17 will include the final specification of the set of
       gestures and the high level API. It will contain the detailed specification of the IDL, events, other
       facilities. MH forecasted a tentative 3-month delay in delivering the 2 part, the software library.
       Partners confirmed that it will not impact their part of development work.

The gesture recognition system - hardware:
    There should not be any component (blocking the user/viewer) farther than 30-40cm in front of the
       display screen, step-proof design.
    HOL and GSA-DDS agreed that the camera FOV will be about 75 degrees horizontally and 60 degrees
    GSA-DDS discussed the advantages and the disadvantages of the two possible camera orientations;
       TB suggested the top side-, while MH and DC suggested the bottom side arrangement of the cameras,
       further the symmetrical 3 cameras arrangement was also suggested to be considered by TB. GSA-
       DDS will decide which arrangement/orientation will be used.

The gesture recognition system - software:
    EB declared that the real-time graphical feedback should have the gesture events immediately when
       recognition occurs.
    From the same reason the high level API of the recognition system should send events like “angle delta
       XYZ” or “translate delta XYZ”
    Partners agreed that the most important gesture commands, which have to be implemented are:
               o Select/highlight/deselect
               o Rotate
               o Pan
               o Zoom/scale
    NT suggested that the combination of select command with other commands like move or rotate in the
       form of a different gesture would be practical for the user, e.g. grab.
    NT, GD and TB suggested that the use of two-hands gestures would be practical for commands like
       scale or zoom; rotate; select a group of objects between hands.
    GD declared that some special gestures for the COMEDIA application would be useful e.g.: selection a
       range of slices, and laser pointer style selection.
    Partners agreed that there should be an easy gesture for undoing the last action.

                                                                                                         Page 3 of 6

                                                                                                 Rev. 1.0, 14/12/2004
Holographic render cluster and user application:

       CS, CRS4 and HOL agreed that they all will have their own render cluster and single PC based render
       CS will suggest the network components (e.g. gigabit switch) of the system
       HOL will suggest the PC main board and the video card for the computer nodes of the cluster
       CS and CRS4 declared that the user application development will be under Linux (Gento distrib.) with
        gcc 3.4 and OpenGL 1.1 or 1.5
       EG will send to HOL the list of packages of Gento Linux CRS4 is using for development

Communication and Display SDK:

       CS and HOL agreed that the Communication SDK and the Display SDK will communicate via OpenGL
        calls: the communication SDK will draw the incoming graphics (OGL command and data stream from
        the User side communication SDK) with OpenGL and the Display SDK will catch these commands with
        an OpenGL wrapper and render the images for the 3D display. The incoming graphics are the result of
        the OGL command and data stream that are coming from the User side communication SDK.
       CS declared that the communication SDK with the OpenGL wrapper will work with some of the legacy
        OpenGL based applications.
       HOL will send an OpenGL wrapper with the Display SDK, which is capable of generating a 3D preview
        on a 2D display latest till end Febr. 2005.

Scalable holographic display:
    1 release of prototype version end Dec 2004

    HOL will provide the DVI hardware upgrade till the end of March 2005.

Collaborative working:

       CS and CRS4 agreed that the collaborative working test will be done on CRS4 10Gigabit intranet
       CS will choose and test the audio and video conferencing components also on CRS4 intranet
       CS will provide a detailed architecture incl. physical connections of a real collaborative working, which
        is between different locations in Europe
       CS confirmed that D14 is the software component needed for the networked part of the Collaborative
       CS confirmed that D15 is the finalized software version of collaborative services

                                                                                                        Page 4 of 6

                                                                                                    Rev. 1.0, 14/12/2004
