Effects of Adaptivity and Other External Variables on Mobile Service Adoption

User Interfaces act as the interaction layer between human and computer and have an important role in system adoption. According to technology acceptance model, acceptance of a system is explained as a function of perceived usefulness and perceived ease of use. Since there are several external variables that have an impact on those variables, the content and interface design of every single application should be addressed specifically to enhance users’ intention to use the system. Adding adaptive features into systems may be one of the approaches to address this phenomenon. This paper identifies external variables including adaptive behavior impacting acceptance of a mobile reservation system through implementation of two prototypes.
