Armed with smartphones and tablet computers, a group of students from an introductory Environmental Studies class test Sustainable U, a mobile gaming application, in the basement of North Hall at the University of Wisconsin–Madison on March 27, 2014. Guided by an online campus map, students must search campus buildings to find signs with QR codes and scan them to discover games or information about waste, water or energy use at each location. The game is under development by the Mobile Learning Incubator in the Division of Information Technology (DoIT) with support from the Office of Sustainability and is expected to launch in fall 2014.
