Three WBI systems were developed with low, medium, and high levels of interactivity, and the effect of interactivity on learners' perceptions was investigated in a real class.
visual fidelity should be maximized subject to scalability and interactivity considerations, environmental effects impact user perception and should be modeled, when possible (and practical) the visualization should reflect the appearance of movers, coherence between the video and the 3D visualization mitigate cognitive dissonance, so discrepancies should be minimized.

On the other hand, interactivity boosted the intervention effect and should be encouraged.
Still, we advise caution with this interpretation as the effect of interactivity may be a between-study difference.
The findings suggest that the effects of interactivity reach a "plateau" at medium and high levels, indicating a diminishing returns effect.
Results indicate moderate effects of interactivity and vividness on social presence and, indirectly, involvement that in turn have strong effects on traditional advertising effectiveness measures.
Although the effects of interactivity and personalization tools on the browsing experience are the subject of previous research, relatively little research focuses on the effect of variable levels of such features on buyers' evaluations of choice goals.
This research investigates the effects of interactivity level on Web user's attitude towards commercial Web sites.
The results indicated that the main effects of interactivity and media richness significantly enhance a consumer's telepresence and affective responses.
