C. J. Karhan, Curtis Riley, Michael Schoeffler · Bell System Technical Journal · 1983
Difficulty finding and understanding information on public telephone instructions has led to problems using public telephones. To overcome these problems a new instruction card was designed. In this paper we discuss the information needs of the public telephone user, a conceptual solution to information presentation, a new standard instruction card design, and laboratory and field evaluations of the new design.
