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 with 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 identifier and are synchronized with the distributed display environment, enabling multi-user support. As many portable devices are not equipped to render content directly, a remotely scene is streamed in. The presented approach scales for large numbers of devices, providing access to a multitude of hands-on techniques for collaborative data analysis.

Research highlights► A framework for the management of various multi-touch devices. ► A method for synchronizing events on multi-touch devices with distributed display environments. ► A method for streaming visualizations from distributed display systems to mobile devices.
