TransWall++ is a large transparent display that can be touched from both sides. Moving beyond conventional displays that isolate users behind their own screens, it enables a new form of interaction in which people communicate face to face. For the Nexperium exhibition, the hardware of the original TransWall, developed in 2013, was fully redesigned with a larger, brighter screen and a refined enclosure, and new content was created to suit the exhibition's theme and target age group.
