AB - Mobile telephony exhibits transmission characteristics and user-interface features distinct from traditional telephony. To study these differences in systems designed for use in commercial airplanes, trains, and automobiles, we used a variety of techniques, including both laboratory and field observations. We found that mobile telephony, viewed from the user's perspective, is quite different from traditional telephone service. In the present paper, we review the assessment techniques that we employed, and consider their strengths and weaknesses for characterizing the performance of mobile telecommunication systems. Our results indicate that there are five major sources of potential user-interface problems in mobile telephony: (1) use of credit cards; (2) system delays; (3) lack of coordination among multiple sources of feedback; (4) the mechanism for completing multiple calls without credit-card reentry; (5) voice dialing. Because solving the problems we have identified does not require new or overly expensive technology, solutions are fairly straightforward to implement during the early design period. However, once units have been manufactured and installed, it can be both very difficult and very expensive to recover from the problems we have identified.
