Human Factors Engineering Studies of the Design and Use of Pushbutton Telephone Sets by R. L. DEININGER. July, 1960. Describes 18 pushbutton layouts tested. "Technological progress in recent years has brought pushbutton signaling from the telephone set within sight of economic feasibility. What, from the user's viewpoint, are the desirable operating characteristics of the key set which should guide development and manufacture? And how do people process information when they key a telephone number?" Referenced in Singing Wires, April 2020. Contributed by Paul Fassbender.
