**6. Quality in emerging technologies: 3D**

One of the most important achievements related to digital video developed in last years has been the next generation 3D stereoscopic contents. Their development is based on the search for illusion of depth perception. After some vain attempts due to a first of generation of 3D developed by anaglyph movies, finally acceptable results have been achieved as seen in the success among users.

3D video offers a new experience to the user, but the acceptance of this experience must be evaluated, in order to draw conclusions about the generation of video contents. That is the reason why quality assessment in 3D systems is more related to the concept of Quality of Experience (QoE) of the user, because it is not just an enhancement of the quality, but a fundamental change in the character of the image.
