The goal of our system is not only suitable for displaying panoramic contents, but also possible to create an intuitive and natural context for multi-user interaction with multimedia content displayed on the i-m-Tube by touch. So, the design of the i-m-Tube meets the following concerns: (1) a controllable high-resolution perception of the tubular display, (2) intuitive interaction and precise manipulation and (3) physical setup as device in our daily life. The high-resolution display is achieved by combining one steerable fovea projector and four peripheral projectors. The large-ranged touch-sensing is based on diffused illumination/FTIR and analyzed by computer vision technology. With a preliminary experiment of the applications on the i-m-Tube, it is exciting to see the i-m-Tube as a new interface for people to meet the interactive multimedia touch in this generation.1.
