Abstract
This paper reports on the design and implementation of an inverted pyramid display for group learning. It is composed of an image generation subsystem, an image reflection subsystem and a software rendering engine. Various 3D models can be loaded into the system and rendered in real-time by the software into four correlative images, each for one side of the inverted pyramid. The display is made of thin semi-transparent acrylic panels. The reflected images appear inside the pyramid and appear to float in mid-air. Users surrounding the display can view different sides of the 3D models and interact with them. Meanwhile, users can see through the display to communicate with each other easily. This kind of design provides an interactive platform for a group of learners to discuss and understand 3D structures and phenomena. This is quite different from existing reflection-based displays, which are mainly designed for exhibition and advertising. Our display system is designed for group learning and facilitates more user communication and interaction.
