User acceptance of context-aware services: self-efficacy, user innovativeness and perceived sensitivity on contextual pressure

Abstract

The aim of this paper is to empirically examine how individual characteristics affect user acceptance of context-aware services such as GPS-based telematics systems and location-based commerce, which together have become highly promising fields for mobile or ubiquitous e-commerce. To examine these individual characteristics, we applied a technology acceptance model to construct an amended model that focuses on three individual differences: self-efficacy, personal innovativeness and perceived sensitivity on contextual pressure. As a result, we discovered that the perceived sensitivity on contextual pressure, which is newly adopted as a construct in this paper, affects behavioural intention in using context-aware services.
