The University of Illinois’ PLATO IV terminal, part of the PLATO educational computer systems the school started developing in the ’60s, has an infrared touch panel that allows students to answer questions by touching the screen. Though other touch-screen devices existed before PLATO IV, it is the first to be widely known and used in Illinois classrooms.
