Multiple mobile devices based virtual display method using electronic LED stick

In this paper, we propose a multiple Mobile Devices based virtual display technique using electronic LED stick. We design a virtual display technique in which each mobile device connects to a server and operates as a cell of the display. The proposed technique uses an electronic LED stick connected to the mobile device via micro USB or BlueTooth to display the real-time message received from the server. It can be scalable in the way that multiple mobile devices participate. Our method can be used as a new performance tool in a concert hall, venue, or stadium, replacing existing large electronic signage and card sections.
