Two possible test scenarios for end-user visual tests, which should be reflected in the above table, are:
i. How does the 3D holoscopic content compare to stereoscopic 3D content (generated using
conventional stereoscopic technology); and
ii. How does the stereoscopic content extracted from the 3D holoscopic content compare to
stereo content generated using conventional stereoscopic technology.
The importance of the second point is related to the fact that, if it can be shown that the stereoscopic
3D content extracted from 3D holoscopic content is comparable to stereoscopic content generated
using conventional stereoscopic imaging techniques, then the production of 3D stereo becomes easier
(i.e., no need for multiple cameras and calibration problems).
Using computer generated content will be an easier option because it is possible to use the same
models generated in 3ds Max ® and carry out the rendering using existing plug-in tools for
stereoscopic and the plug-in tools developed by Brunel University for holoscopic content. Hence, the
same content is generated and displayed by the two technologies.
For real data, a concept which will allow the same content to be captured using the holoscopic camera
and a pair of 2D cameras is needed. One way to achieve this is by using a motion control system and
program a camera movement when capturing a static scene to simulate motion: 1st take will be with
the 3D holoscopic camera and the 2nd take will be with a pair of stereo cameras.
5.2 TIME PLAN
The time plan for the tests corresponds to the timing of Task 7.3 – “User Perception and Usability
Testing”, which starts in project month 29 and continues until month 34. The exceptions are the tasks
to be carried out by Brunel University on viewing and a small number of earlier tests at RBB focusing
on the optimisation of the processes before involving costly professional teams. The timing for these
tests is earlier to correspond with the availability of enough test candidates and personnel and also to
provide useful input at an earlier stage.
The professional user tests are planned at the start of the task so the time gap between producing the
showcases and developing and using the test-bed is not too great, and the experience is still fresh in
the candidates’ minds.
The end-user tests with the individual elements of the system are timed at the beginning of the task to
allow feedback and refining of the testing concept if necessary for the final end-user tests with the
