Habit has been investigated as an antecedent of the information systems usage in a few literatures recent years. But little effort has been found on the determinants of habit itself in the information systems research. Drawing upon the insights from goal-directed behavior, habit/automaticity perspective, and IS continuance model, this paper proposes a research model for understanding the antecedents of the individual information technology usage habit. This study suggest that individual satisfaction, perceived enjoyment and user experience positively influence the strength of usage habit, and that perceived usefulness, confirmation of expectation and perceived enjoyment positively affect satisfaction. The implications are discussed, and contributions of this study are presented
