CGLXTouch: A multi-user multi-touch approach for ultra-high-resolution collaborative workspaces

This paper presents an approach for empowering collaborative workspaces through ultra-high-resolution tiled display environments concurrently interfaced by multiple multi-touch devices. Multi-touch table devices are supported along with portable multi-touch tablet and phone devices, which can be added to and removed from the system on the fly. Events from these devices are tagged with a device id and are synchronized with the distributed display environment enabling multi-user support. As portable devices are not equipped to render content directly, a rendered viewpoint is streamed in. The presented approach scales for large numbers of devices, providing a multitude of hands-on techniques for collaborative data analysis.
