A Study of Interactive Three Dimensional Free Form Display

点击翻译按钮获取中文摘要

We developed a touch-capable 3D displaying device for tabletop systems called Ficon. A Ficon has a 2.5-dimensional shape for providing tangible dynamic 3D visual. While most tangible devices for tabletops display their associating information around themselves, a Ficon displays such information on its top touch-capable surface. A Ficon consists of a bundle of optical fibers with a polished flat bottom surface. When a Ficon is placed on the surface of a tabletop system, the light from the bottom surface is conducted to the top surface through the optical fibers, allowing the system to control the visuals of the Ficon by displaying images at its position. Two methods for constructing a free-form 3D display using a Ficon are introduced: the use of a CNC milling machine to create a pre-shaped Ficon from a 3D model, and a building-block approach using a set of primitive Ficons.
