Microsoft Research has a compelling software product called ConferenceXP (now in version 3.0).
ConferenceXP is an initiative of Microsoft Research. We’re exploring how to make wireless classrooms, collaboration, and distance learning a compelling, rich experience by assuming the availability of emerging and enabling technologies, such as high-bandwidth wireless devices, Tablet PCs, and the advanced features in Microsoft® Windows® XP.
The ConferenceXP research platform enables researchers and developers to create distributed applications that take advantage of ConferenceXP technology as well as Tablet PCs and wireless networks. It also enables them to develop the collaborative tools and applications they need without having to build them from the ground up. By partnering with research organizations and universities, the ConferenceXP research platform combines the academic community’s expertise in the learning sciences with Microsoft’s expertise in technology.
