Applying the Theory of Task-Technology Fit to Mobile Technology: The Role of User Mobility

In this paper, the authors apply the theory of task technology fit to mobile technology, focusing specifically on the role of user mobility. They describe the results of an empirical study of 216 business users of mobile devices that included various smart phones, Personal Digital Assistants (PDAs), and laptop computers. The findings suggest that the relationship between task difficulty and functional requirements of the mobile devices is stronger for highly mobile users than for less mobile users; user mobility is associated with increased user-perceived importance of a number of non-functional features; and for a number of functions and features, highly mobile users indicated a stronger relationship between task-technology fit, and overall evaluation of the technology.
