Visual simulation can be efficiently performed using programmable graphics hardware. However, in utilizing hardware to maximize throughput, it is important not to constrain interactivity. We present a method of using the graphics hardware while maintaining full interactivity during simulation exploration. This interactivity involves: temporal exploration, data probing and modification, simulati...

This paper describes an experimental study of interactivity effects in electronically mediated feedback communication. Conversational interactivity is expected to be lower when pairs of subjects are using mixed communication media. Performance feedback is expected to be less successful when interactivity is reduced, especially when the properties of the communication environment violate the nor...

Interactivity has been regarded as the unique characteristic of the Internet that distinguishes from traditional mass media, and it should be considered as an indispensable variable in the investigation of effects and effectiveness of interactive advertising (Leckenby and Li 2000). The notion of the active role of the consumer proposed by Pavlou and Stewart (2000) reflects the importance of int...

Political blogs are distinguished by their heightened interactivity, allowing users to participate directly in the political process. Does the interactivity afforded by political blogs really serve the public interest by contributing to deliberative democracy? A longitudinal between-subjects experiment was conducted during the week preceding an election to answer this question. Results suggest ...

Today, educators have raised important questions about the quality of interactivity or interaction between students and between teachers and their students. The author has investigated interactivity, completed a doctor’s degree from a distance education school and teaches online for the University of Phoenix. The discussion highlights interactivity research studies, outlines vital online teache...
