Abstract— Distance learning aims to deliver education to students who are not physically on site with teachers, and try to enhance the accessibility for education resources through Internet. Here in Taiwan, it is still at the early stage of distance learning environment construction, and most distance learning classes support synchronous learning model that teachers and students are located in geographically dispersed classrooms at the same time. For economical considerations, there are demands of low cost solutions to multicast the learning resources to students. It is the purpose of this paper to share the design and implementation experiences of constructing a configurable display network for distance learning. A dynamic display network for a learning class is constructed by a root display node sharing the learning resources, and other display nodes joint to the display network in succession. To reduce the cost and complexity of sharing the learning resources, this paper proposed a multiple display system based on the embedded system to assist in the distance learning. A display node of multiple display system is a software component bundled with an embedded wireless module connecting to a display projector or panel in a classroom. Besides the design of display nodes, a node soliciting algorithm is also presented to articulate the construction of the learning display network.
