The pCubee consists of five LCD screens arranged as a cubic “fish tank” box that viewers can pick up, tilt, shake or turn to watch the 3D content or play games with virtual objects that seem to be within the box. Instead of stereoscopy, the device uses a principle called motion parallax, which is one of the means by which we usually perceive depth in a three dimensional scene. Motion parallax is a cue the brain is able to use to sense depth, because the movements of objects across our field of view depends on their relative distance from us. Having the box move means viewers do not need to move their heads to see the effect. 3D TV — Without the Glasses (w/ Video) More information: The pCubee will have many more applications than 3D games, since it also has the potential to become a CAD-CAM platform, and could be used in museum displays. It was awarded Best Demonstration at the 2009 ACM International Conference on Multimedia in Beijing. * UBC research page: hct.ece.ubc.ca/research/pcubee/* pCubee site: www.cubee.ca/ © 2010 PhysOrg.com pCubee: a Perspective-Corrected Handheld Cubic Display The five flat-panel LCD screens on the sides of the box are driven by three graphics pipelines. The perspective rendered on the screens is kept synchronized with the user’s view by a motion tracker that monitors both the user’s head and the pCubee box. That, and the real-time physics simulation engine, make the display look like a tank containing real objects. The box allows you to view a static 3D scene, or you can manipulate the box to navigate through the scene or play with objects colliding in the scene. You can also manipulate virtual objects using a stylus.pCubee was developed at the Human Communication Technologies Laboratory at the University of British Columbia in Canada. Leader of the engineering team, Sidney Fels, said the group wanted to offer “a fish-tank-like experience” in a handheld device. Fels hopes the pCubee will be commercially available soon, but the researchers are continuing to refine the design, and may replace the current LCD panels with OLED screens. They are also building pCubees in different sizes for different applications.
