“Mirage” represents the world’s first hands-on and immersion-type performing arts. Art performance group Grinder-Man used the SR system (an alternative reality technology) developed by the Adaptive Intelligence Team of the Riken Brain Science Institute (BSI) to create this work. The group gave the first performance of “Mirage” at the National Museum of Emerging Science and Innovation (Miraikan, Tokyo) in August 2012, and received an enthusiastic response. Its popularity crossed the ocean and led to the invitation of the Ars Electronica Festival, one of the world’s major media art festivals held in Linz, Austria in September every year. The festival in 2014 hosted programs across the City of Linz, and Grinder-Man performed Mirage at Mariendom (the New Cathedral) located in the heart of the city.
