Getting into vitual reality

The topic of this special issue is immersive interactive technologies. It represents one of the “modern” topics in DSP and is at the intersection of the traditionally separate areas of computer animation, computer vision, graphics, speech and audio processing, image and video processing, and communications (not to mention psychology, physiology, kinesiology, and control). Such R&D topics act as a catalyst in bringing together researchers from outside the digital signal processing area, and this is clear by looking at the authors in this issue. Each article brings a different perspective to the discussion.
