In a talk delivered at the 2009 CESA Developer's Conference, or CEDEC, in Yokohama, Sony Computer Entertainment producer Tatsuya Suzuki and researcher Jun Fujiki outlined the development of echochrome, which has its roots in one of Fujiki's research projects.
Suzuki says that he admitted defeat when he first saw the "OLE Coordinate System" at the Japan Media Arts Festival back in 2007. This technology, which detected a character's environmental interaction based on camera positioning, was the prototype of what would later become the PS3/PSP title echochrome. It was originally created by Jun Fujiki, a researcher at the Kyushu University and Japan Society for the Promotion of Science.
