3D is often considered as the next step in the development of home’s television. So far, it has also created a lot of interest in the digital cinemas.

In both cases, several difficulties has to be considered. These difficulties come from the camera capturing over the encoding and transmission stage to the rendering on the display or the cinema screen. Each of these steps need to be re-evaluated in the 3D context.

The 3D activities of the IVC team have started a long time ago before the current hype of 3DTV. The research is focused on the influence of the modern technology and on the human observer. In particular, 3DTV adds several constraints and additions to the previous measured video quality.


Besides the Quality of Experience, the visual discomfort need to be resolved. The work is underway to create reliable measure of the discomfort. The integration into an overall quality score is one of the main goal.

Our unique 3D platform with its multitude of display and measurement equipment are located in a standardized environment that allows us to develop and to compare different technologies and subjective test methods.

The strong international cooperation of the IVC team helps to verify the results with several different laboratories. IVC research group is also co-chairing the activities of the 3DTV group in Video Quality Experts Group (VQEG). In this effort, we are preparing a new ITU standard which will take the role of the well-known ITU-R BT.500 for 3DTV.

Research Areas

Visual Fatigue

Viewing 3D content on 3D displays is an unique experience. Nevertheless, it is an unnatural condition for the eyes as the depth effect is created by the disparity of the left and the right view on a flat screen instead of having a real object at the corresponding location.

Thus, it may be more exhausting to watch 3D than 2D.

This question is investigated by the IVC team by doing subjective experiments. For example, performance task experiments were recorded with our eyetracker equipment. Several indicators were evaluated both for low level perception and for the task performance itself . In addition to the tests that are dedicated to 3D visual fatigue, optometric tests are also regularly performed, e.g. prism factility tests or Maddox rod.

Subjective Test Method

For measuring the perceived quality on a 2D screen, several established methods exist. However, they have failed because using a 3D screen covers additional aspects besides the video quality.

One of the possibility is to measure this different aspects with different scales, e.g. depth effect, visual discomfort, and naturalness. However, this way of evaluation creates huge cost for the subjective test.

Thus, a reliable method is required for performing a subjective experiment with a single session.


On an ideal screen, the views for the left and the right eye are perfectly separated. However, most of today’s displays suffer from a spread of light from one view into the other(s). The observer perceives ghosting effects.

Our work focuses on reducing such effects, for example on autostereoscopic screens and on measuring the impact of the crosstalk on the apprectiation of the 3D viewing experience.
