The thought of a touchscreen was first described and revealed by E.A. Johnson in 1965 Within the early 1970s, the primary touchscreen was developed by Frank Beck and Bent Stumpe, engineers at CERN The physical product was first created and utilized in 1973 The first resistive touchscreen was developed by George Samuel Hurst in 1975 but wasn’t produced and used till 1982.
