Abstract
Although most users currently receive web services from web browser interfaces, pervasive computing is emerging and offering new ways of accessing Internet applications from any device, any time and anywhere. It is not only a technological change, but a philosophical and psychological one. Our research project investigated the theoretical concepts of pervasive computing as well as their practical applications, by using cellular phones as the pervasive device to access a web application prototype, the voice-enabled web system (VWS), through the voice user interface technology. The acceptance rate of consumers on new pervasive interfaces was studied using factors (including perceived usefulness, perceived ease of use, attitude, subjective norms, perceived behavioural control and fun) adapted from technology acceptance theories. Although our empirical findings were in general consistent with the findings from several prior studies on various information technologies, there were still some discrepancies. Our overall research results, including the implications derived from the user study, may be useful for the purpose of designing and developing successful business applications based on VWS.
