AR-Span: A Multi-Screen Adaptive Displaying System Using Smart Handheld Devices Based on Mobile Networks

In this paper, we design and implement a multi-screen adaptive displaying system, called AR-Span, which can enable the assembling of heterogeneous mobile devices into one multi-screen displaying equipment. The AR-Span system consists of multiple mobile devices with various screen sizes and a dedicated server communicating and coordinating among these mobile devices. AR-Span can cooperatively display a complete image on multiple mobile devices. In addition, AR-Span can precisely partition a video and synchronically play the video on multiple mobile devices. Furthermore, AR-Span can arbitrarily customize an electronic marquee on multiple mobile devices. In particular, AR-Span can immediately adjust and control the displayed content in an augmented reality based manipulation manner. Experimental results show that AR-Span manipulates the desired content much faster than existing methods/systems and can significantly reduce the total operating time. Moreover, AR-Span can improve the displaying time inconsistency and unsynchronized content gap on heterogeneous mobile devices.
