Virtual environments – which are an essential part of Dual and Mixed Realities – can be used to create new applications and to enhance already existing applications in the real world.
Besides that, existing sensors in the real world can be used to enhance the virtual world as well.

Even well known techniques, like the Kalman-filter, can be seen as an example for this type of application: Sensor measurements in grounded reality (the real world) are brought into virtual environments in form of models that describe the error distribution of the sensors. The virtual environments can then be used to make a prediction for the next measurement in grounded reality. Both results – the prediction and the measurement – are used to refine the virtual world and to bring more accurate sensor measurements into the real world.

On a more philosophical level, it can be argued that all Mixed/Blended/Dual/Grounded and Virtual realities exist within one reality. PolySocial Reality (PoSR) is a theoretical perspective that subsumes other 'reality' paradigm models while providing a framework to express their behaviors. PoSR is the aggregate of all the experienced 'locations' and 'communications' of all individual people in multiple networks at the same or different times. PoSR describes the network transaction space that people traverse with others to maintain social relationships via various apps, mobile services, sensors, platforms, technologies and conversation spaces. At its most positive, PoSR extends our capacity for social relations, at its worst, it fragments and isolates people from each other. The underpinnings of PoSR were developed for LAMDa’11, and papers describing it in detail can be found here:
