Prof. Hiroshi Ishii is a visionary of HCI (Human-Computer Interaction). In order to go beyond the current dominant paradigm of “Painted Bits” or Graphical User Interface (GUI), he presented the visions of “Tangible Bits” in 1997 and "Radical Atoms" in 2012. He explores the Tangible Bits & Radical Atoms visions to seamlessly couple the dual world of bits and atoms by giving dynamic physical form to digital information and computation.
