Twin-World Mediator
The Twin-World Mediator (TWM) is a component which manages the communication between the virtual world and the real world.
Two types of key functionality of the Twin-World Mediator are:
- Bi-directional data exchange between the real and the virtual world (and feedback notification).
- Automatic code generation for controlling real and virtual devices.
The following figure depicts the TWM architecture.

The TWM was developed for Second Life. TWM development was superseded by OpenLibrary, a set of APIs on top of OpenSim.
