On a Synchronizing Module for Extended Web Displaying System Based on Multiple Tablet Devices

We implemented a synchronization module for tablet devices to support collaborative works based on Web contents. The module enables multiple tablet devices to display web contents as one large display. In this paper, we show the implementation of the module. Pair swipe operations are adopted to determine the position of the device and the UDP is used for broadcasting synchronous messages. We show two applications based on the synchronization module, one is a piano score system, and map viewing system.
