We have been testing Microsoft’s whiteboard software with our touch screens and using it for markup and sharing of images.
For example we started with Bluebeam, one of our favorite applications for use with the 55″ lift & tilt touch-screen table, took a snapshot of a plan then loaded that into Microsoft Whiteboard. This immediately enabled us to share with multiple devices, even iPhones, while doing markup on the large screen.
Bluebeam also provides a collaboration capability to enable real-time interaction between Bluebeam users anywhere.
As a whiteboard application the Windows Whiteboard application has all the usual features such as pen and color selection. Collaboration with other devices that enables multi-way interaction, is straightforward, as simple as sending a link.
