From the compact disc to the wii, the Japanese have always been successful at coming up with some of the greatest inventions. Now they have come up with a Substitutional Reality System that combines the past and present in a dynamic and technologically advanced manner. The device fuses performance art and perceived reality experiences in the project entitled “mirage”. It allows the user to engage in a simulation of the flow of time travel, where the past and present become mixed together, as an omni-directional camera and motion sensor work simultaneously to allow the user to observe a combination of live video recordings from the past and present, thus making the it hard to distinguish between what’s real and what’s not. When the user faces the same direction in which motion took place, pre-recorded scenes are immediately introduced while the device makes it seem as if though the user is still looking at a live video stream. The device was developed in a laboratory for adaptive intelligence at the Riken Brain Science Institute.
