AT and IU refer to users' positive feelings and evaluations of using smartphones and their intentions to (continue to) use smartphones, respectively. This study defines PU and PEOU as the degrees to which users believe that their job performance can be enhanced by using smartphones and that using smartphones is free of physical and mental effort. 20 Therefore, TAM is a logical framework for empirically studying the role played by screen size in determining user acceptance of smartphones. 907).” 8 For example, prior studies have established the validity of TAM as an effective theoretical model especially in exploring user acceptance of various mobile-based technologies and services, including smartphones, 9, 10 e-book readers, 11 mobile TV, 12 Internet, 13, 14 games, 15, 16 learning, 17 banking, 18 chatting, 19 and long-term evolution (LTE) services. This TAM framework has been extensively replicated and validated by numerous studies that attempt to predict user acceptance of novel technologies, systems, or services, thereby confirming “the significant explanatory power and parsimony of TAM (p. When positive attitude is formed by enhanced PU and PEOU, users are more likely to show stronger behavioral intention (IU) to use the technology. Both PU and PEOU, along with external factors surrounding unique affordances and characteristics of the technology (e.g., screen size), are then believed to determine user attitude (AT) toward the technology. A particular technology is perceived to be useful if users believe that the operation of the technology is easy and convenient. The original TAM features perceived usefulness (PU) and perceived ease of use (PEOU) as the primary determinants of technology adoption. TAM has frequently been utilized as a theoretical framework that allows systematic predictions of user acceptance of information and communication technologies. Does screen size really matter? Are there psychological factors other than the intuitive notion of “the bigger the better” that explain the role of screen size? To answer these and related questions, this study explicates the process through which screen size determines user acceptance of smartphones by examining perceived control and perceived affective quality as key utilitarian and hedonic factors that are closely associated with screen size and integrating them with the Technology Acceptance Model (TAM). However, the essential question of whether screen size indeed significantly contributes to shaping user perceptions and acceptance of smartphones has not been sufficiently addressed in empirical research. 3, 4 Screen size is now regarded as a key choice factor among smartphones, equally as important as brand reputation, price, and operating system. Recent polls on smartphone adoption and usage reveal that the screen size of smartphones has steadily grown from 2008 to the present, and nearly one-third of smartphones sold in 2012 had a screen size larger than 4.5 inches. For example, the trend in newer phones by leading manufacturers, such as Samsung Galaxy Note 3 (5.7 inch screen), LG Optimus G Pro (5.5 inch screen), and HTC One Max (5.9 inch screen), suggests that large screens are preferred over small screens. W hile smartphones have become near-ubiquitous tools for communication with a rapid adoption rate, 1, 2 there has been increasing evidence of user preference for smartphones with large screens in recent years.
