Objectives of Experiments

The objective of the PANORAMA field trials is to prepare enhanced services and to show the usefulness of stereoscopic imaging to the public and to potential professional users in the areas of 'stereoscopic videoconferencing', 'medical imaging' and 'industrial applications'. The PANORAMA field trials therefore are dedicated towards non-expert users at public demonstrations and towards expert users at special occasions.

Description of experiments / platforms

Due to hardware constraints (only one complete system chain available), we have the following limitations for the final demonstration and the field experiments:
Only one direction of the conferencing situation will have a full stereoscopic set-up; this direction will be transmitted over ATM.
For the reverse direction, standard monoscopic videoconferencing equipment will be provided. The viewing person at this side (which is captured by a stereoscopic camera) must be well acquainted with the whole set-up, i.e. (s)he must react as if (s)he also saw the partner on a stereoscopic screen.
Transmission is planned between two ATM-equipped sites, which are likely to be HHI and Deutsche Telekom/DeTeBerkom in Berlin. The same system will also be used for transmission to Forschungsgruppe OP2000 at Berlin-Buch. The advantage is the short distance between these locations, which will allow equipment to be moved easily and enable hardware experts to solve problems quickly. Here we will have a real 3-D teleconferencing situation at one side, which will also be shown to marketing experts of the field.
In addition, we plan an exploratory test series under controlled conditions, which will be performed at HHI by an external company. The system will be assessed by at least ten different viewers who will be users familiar with standard visual communications (teleconferencing) equipment. The different features of the system will be explained to these people, who will perform specified tests, whose experiences and criticisms will be evaluated. Although this is not a full field trial (because only one system will be available), we expect interesting results showing the advantages and weaknesses of the system.
Within this test series, we plan to use two different displays. One is the autostereoscopic display of the final set-up and the other is a PC-based stereoscopic system with shutter glasses. Though glasses cannot be employed in a true videoconferencing situation, we can use them here due to the asymmetric set-up with a monoscopic display and a trained partner at the remote side. It is very important to investigate the influences of the screen size, spatial resolution and distance from the viewing person to the screen will have on the telepresence illusion. In this respect a shutter glass system is more flexible than an autostereoscopic display. In addition, the user will be allowed to regulate the baseline between the virtual cameras, in order to get the individually-optimum stereoscopic impression. These trials will be performed within a local loop, not using ATM transmission.
In addition, we plan to use parts of the demonstrator within the national German project MINT ('Multimedia on Integrated Networks and Terminals', sponsored by the German Ministry for Research and Education), where the application of viewpoint adaptation to entertainment, like 3-D TV and 3-D games, will be investigated during the third and fourth quarter of 1998. This project is being undertaken in co-operation with industrial partners, and these demonstrations will address potential users. This demonstration may also be shown at the CeBIT Home '98 fair (26-30 August 98).
Another possibility is an aircraft engine inspection test but we could not at this point guarantee exactly where/when that would take place, since the opportunities to experiment using very expensive aircraft engines are rare. The time for this would be after completion of the endoscope calibration workpackage.
One other possibility which we could envisage is a remote handling field trial using a remote robot and our force reflecting joystick control system. We have all this equipment running at AEA, Culham with 'conventional' stereo viewing systems.

For the medical trials a group of expert users/ evaluators from the European Society of Neuro-radiologists will assess:

In preparation for the medical field trials, MDC is working on the clinical routine with 3D-imaging systems such as is 3D-laparoscopy and 3D-operation microscopy. In addition a 3D-camera to transmit from the operation room has been installed. Conceptual work has been done to integrate a 3D-camera directly into an operation lamp. MDC is setting up an intra-clinical 3D-video and audio network.
To transmit the 3D live images to the clinical and scientific partners (GMD St. Augustin, Klinik rechts der Isar, M√ľnchen etc.), MDC is working with a real-time coding system, which allows transmission over a G.703 34 Mbit/s channel. Facilities for transmission over satellite connections have already been installed.
All this work has been performed based on stereoscopic techniques and stereoscopic cameras. This demonstrates the acceptance and usefulness of 3D-imaging in medicine. Parallel to this MDC is prepared to test the new developments of the soft- and hardware groups of the PANORAMA partners and to integrate the results in their 3D-systems.
The responsibilities for the different organisations hosting the experiments is as follows:
