Interaction will be predominantly asynchronous. While this represents more mediated settings than Type I, the tools are being used as substitutes for other forms of technology lying below the threshold rather than as a fully developed form in their own right.

The potential of technology is being exploited to develop effective and sophisticated two way connective communication, potentially allowing extension of education to new social groups. Learners are not merely recipients of information transmitted to them by innovative means, but are involved in the formation of that information. Several large corporations are developing Type III systems for workforce training and upgrading on their intranet systems. In Type I computers are illustrative, supporting person to person communication.
