Interactivity concepts examined: Response time, hypertext, role taking, and multimodality

This paper elaborates on the interactivity concept and theorizes the impact of this feature on new media message processing. The early part of this paper aims to solidify a conceptual definition of interactivity. To do so, it examines many interactive components of the new medium and discusses the potential value of current interactivity concepts. For relevant conceptualizations, potential interactions with other characteristics of the medium are also inspected. The latter part of the paper focused on the empirical evidence of interactivity concepts within the limited scope of human-computer interaction.
