In recent years, information technology has advanced at a pace that few would have anticipated. It has been estimated that the computing power of the modem desktop computer has been increasing at the rate of 1000% per decade. In combination with the development of personal computers, the advent of networks and the world wide web provide unprecedented access to information and computing power. However, the problem of developing useful user interfaces remains a problem. In many military and commercial settings, the increased computing power offered by current information technology remains unexploited because of user interfaces that are difficult to use. This thesis reports on the examination of constructs related to user acceptance of information systems from two disciplines, human-computer interaction (HCI) and management information systems (MIS). More specifically, research was conducted to evaluate the possibility of overlap between the two divergent fields. The Technology Acceptance Model (TAM) from MIS research was examined in light of the HCI constructs of efficiency, effectiveness, and satisfaction. Of interest was the impact of efficiency, effectiveness, and satisfaction on the formulation of user perceptions of ease of use. The empirical data suggests that satisfaction plays a major role in the formulation of user perceptions (p<0.01), while the role of efficiency and effectiveness are minimal.
