Augmented reality

An augmented reality is a reality where both the imaginairy world as the virtual world meet, without being worlds apart. Images of real life would be taken and blended with information. You could interpret it as a duplicate of the real world. Augmented reality can be used as a way to find an answer to problems you can't solve yourself. It will visualize an environment and this way you can find out how certain systems or creatures react to eachother in a complex situation. The ARENA for example, short for Augmented Reality Environment at APL, provides such environment.
