The literature on interactivity includes many assumptions and some definitions but few tools for operationalizing the concept of interactivity in computer-mediated environments. This article takes an early step in filling that gap. In-depth interviews with 10 individuals who work and teach in the field of interactive communication led to a conceptual definition of interactivity based on six dimensions: direction of communication, time flexibility, sense of place, level of control, responsiveness, and perceived purpose of communication. Suggestions are made for applying these dimensions to multiple forms of computer-mediated communication. Future research should empirically test the existence and application of these dimensions.
