Developers at the Computer Human Interface conference and elsewhere this week have been showing new approaches to displays that could allow interaction with a perceived 3D environment. The pCube (video below) from the University of British Columbia is unique in depending on LCDs on each side to create a 3D perspective accurate from every angle. Besides letting users view an object from every angle, it has an accelerometer to respond to motion and sensors that respond to an in-air device to interact with the inside of the cube, although it doesn't yet support touch.
