360° Display from Sony

At Ceatec exhibition 2009 in Tokio Sony presented a prototype of a real volumetric 3D-display. The display has a cylindrical form of 27 cm height and 13 cm diameter and can display stereoscopic images at 24bit color depth to multiple users simultaneously. Although Sony does not comment on the technology used, it seems that the cylinder contains a rotating array of LEDs behind a parallax barrier. This is similar to the Seelinder prototype which has been presented at SIGGRAPH 2005. On Sony’s website (in japanese) it says the display resolution is 96 × 128 pixels at 360 viewpoints distributed over 360 degrees. There is no information about volume refresh rate however.

Sony doesn’t seem quite sure what to do with it at the moment, but says it’s considering various applications, like digital signage, medical imaging, a digital photo frame or even a 3D videophone for the home. As for when it might come to market, Sony said that for now they will be soliciting ideas on how it might be used and then will consider future plans. “It all depends on the application,” they said regarding commercialization. “If we can develop a good application then we’ll invest more.” – Network World

At Siggraph 2010 the same display was presented under the brand name RayModeler.
