No 12COMMUNICATIONS OF THE ACM December 2003/Vol. 46, No. 12 49 The rapid growth of mobile telephony has provided a foundation for m-commerce, namely, e-commerce activities carried out via a mobile device, such as a cell phone or PDA [8]. Proponents of m-commerce claim its growth and scale will exceed that of e-commerce. Such increases, however, appear slower than pre￾dicted for various reasons, including delays in technology standardization, limited mobile Inter￾net coverage, and poor service quality. UNDERSTANDING THE UNIQUE CHARACTERISTICS OF M-COMMERCE TO ENHANCE AND IMPROVE THE USER INTERFACE. INTERFACE DESIGN for Mobile Commerce BY YOUNG EUN LEE AND IZAK BENBASAT Technology development is seriously challenged when users are slow to adopt the new technology; therefore, among the many cited reasons for slow growth, we focus here on the consumer perspective. We investigated the dis￾tinct characteristics of m-commerce in order to discover its strengths and vul￾nerabilities and are able to offer design prescriptions to enhance the interactiv￾ity of the interface, hence encouraging users to adopt m-commerce. Two characteristics of the mobile Internet and its devices define con￾sumer purchase patterns: the mobile setting and the mobile device con￾straints. While consumers enrich their shopping experience by taking advan￾tage of instant Internet access (mobile setting), current mobile devices also constrain consumers, due to their slow CPUs and limited processing power
