摘 要：At the aim of delivering education to students who are physically departed from their teachers to access more education resources via Internet, distance learning becomes a trend in the teaching field. Currently, synchronous learning model are mostly supported for those users located in geographically dispersed classrooms at this early stage of distance learning environment construction in Taiwan. To consider economically, the solution to reach a low-cost goal of providing learning resources for students is quite demanded. Therefore, the paper will indicate that the design and implementation experiences of constructing a configurable display network for distance learning. A root display node sharing the learning resources builds a dynamic display network for a distance learning while other display nodes joint to it in succession. In this paper, we proposed an idea of a multiple display embedded system to assist in the distance learning for lowering the cost and complexity of sharing the learning resources. In a multiple display system, a display node is a software component bundled with an embedded wireless module connecting to a display projector or panel in a classroom. Moreover, soft component of display node is implemented an interface for mobile device to make a remote control. We also presented a node soliciting algorithm to articulate the construction of the learning display network, including of the design of display nodes.
