This paper is to understand that how easy and convenient for consumers to use mobile services. Mobile service is a combined hardware and software with information technology. Especially to meet the needs of users of mobile applications, consumer mobile services were identified in the context of usability. For usability measurement and evaluation devices such as appliances, S/W, were the main target, and that applies to a range of changes, such as a personal information terminal(PDA), mobile phones, and wired and wireless integrated services is expanding This study extended the Technology Acceptance Model(TAM) by examining the roles of two aspects of mobile applications usage characteristics with usability. The usability is divided into learnability, efficiency, memorability, errors and satisfaction. And it is motivation that can be understood as a useful and easy to use mobile applications. This empirical study validates the proposed research model and hypotheses, and found that the hypotheses can be supported. Finally, it was identify the phenomena that derive from the causal relationships in usability, and consider their implications.
