Digital scope on communication sheet for media interaction

This paper introduces an interface platform to visualize location-specific media on lightweight displays that are placed and moved over a two dimensional map. The position of each display in the 2D space is dynamically sensed. The media data are transmitted to the detected display accordingly via a newly invented communication sheet underneath the map. Users can move the display on the sheet to magnify and explore interesting spots or items, while the contents received are image and video at different levels of detail. The platform is multi-user oriented, power efficient, and capable of performing multi-channel wide bandwidth transmission. As a physical medium, the communication sheet provides a large 2D space for interaction that a flat screen and touch panel cannot achieve. We have done experiments on the designed platform for verifying its effectiveness in education and exposition. These experiments have demonstrated its promising features in multimedia presentation.
