The immersive stereoscopic room (Computer-Animated Virtual Environment, CAVE) is a four walls multi-projector system that functions with 40 off the shelf projectors controlled by 12 PC's. This architecture operates in passive stereo and provides high luminosity and 2000x2000 pixel resolution on each of the walls (16 million pixels in total).
Low cost, versatility and high resolution are some of the characteristics of the CAVE which works with any mix of a wide range of projector models that can be substituted at any moment for more modern or cheaper ones. The uniformity of the final image is achieved using self-calibration software, which adapts each of the 40 projections and guarantees the concordance and continuity of the system.
Users interact wirelessly with objects and the virtual scene through their gestures. The new interaction system is intended to be transparent and highly ergonomic. It is based on two Kinect sensors placed at 90 degrees to each other that work in unison, detecting the movements and positions of the main joints of the person inside the CAVE in real time.
The system adapts the image perspective to the head position of the users in real time, allowing them to select and modify the characteristics of the virtual objects with gestures, zooming in or moving them around themselves in order to inspect and see specific areas of these objects more clearly.
The self-calibration algorithm is based on the projection of patterns and on the capture of these patterns by four digital cameras that are controlled by a PC. Its own visualization software guarantees that any digital model can be inspected using the interaction methods defined for the navigation, selection and manipulation of virtual objects.
Objects are visualised in greater detail and at a lower cost than is offered by current systems. The CAVE thus saves money and time, improving the quality of work, products and technology transfer.
