Tool lists that will be discussed  Collaborative Virtual Environments (CVEs)  Google Docs  Twitter  Microsoft Surface

Tools  Collaborative Virtual Environments (CVEs) are computer-enabled, distributed virtual spaces or places in which people can meet and interact with others, with agents and with virtual objects.

Tools  Google Docs: an online document editing and sharing tool: Docs.google.com

Tools  Twitter: communicate and stay connected through the exchange of quick, frequent answers to one simple question: What are you doing?

Tools  Microsoft Surface: blogs.zdnet.comwww.microsoft-surface.name/

Classification of technologies  Based on the notions of time and space

Class exercise: put the following tools into the time/place matrix  Wiki   Web conferencing  Online forum  Mailing list  Instant messaging  Physical bulletin board in the hallway  Chat room  Shared Whiteboard  Collaborative Virtual Environments (CVEs)  Microsoft Surface  Social map/tool (Frappr)  Google Docs  Facebook  Twitter
