"Dual reality" is the concept of maintaining two worlds, one virtual and one real, that reflect, influence, and merge into each other by means of deeply embedded sensor/actuator networks. Both the real and virtual components of a dual reality are complete unto themselves, but are enriched by their mutual interaction. The dual reality Media Lab is an example of such a dual reality, as enabled the Plug sensor/actuator network that links our actual lab space to a virtual lab space in the Second Life online virtual world.
