Person-Computer Interface using Touch Screen Devices

Abstract

Within recent years, the advent of microprocessor technology and reduction in cost of optical electronic devices has allowed Touch Screen Devices (TSD's) to become a viable option for person-computer interface. Basically, TSD's consist of any of a number of different technologies that can overlay a CRT which permits an operator to make a selection by touching a predesignated area of the CRT screen. To date, the authors have performed a literature search, user interviews and field evaluations of TSD's and have noted a variety of advantages/disadvantages associated with the technologies available and problems with the selection/implementation of TSD's.
