Facts about tools What happens in face-to-face

communication/collaboration? Non-verbal cues:

spatial orientation, body posture, hand gesture, glancing, gaze and eye contact, facial expression, awareness of others, non-verbal turn-taking cues.

An example of what has been enhanced

Telephone Videoconferencing Web conferencing

Concepts Synchronous:

It provides the necessary mechanisms for people working together as if they were working face-to-face,

All the persons sharing the workspace can view and update the same work space concurrently,

Examples: face to face, videoconferencing, audio conferencing, ICQ, MSN Messenger

Asynchronous: It means that interactions among people are not in real-

time, Normally, only one person at a time can access the

workspace, viewing and modifying its contents, Example: Email, blogs, wiki, intranets

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? http://twitter.com/

Tools Microsoft Surface:

Affordances of communication media (Kraut et al. 2002 ) Different media/technologies provide different affordance or resources that
