Audience Silhouettes
Radu-Daniel Vatavu · 2015
We introduce audience silhouettes for TV, which are visual representations of viewers' body movements displayed in real-time on top of television content. With their minimal visual cues and their ability to convey presence and to leverage interactions via non-verbal kinesics, audience silhouettes are strong candidates for implementing Oehlberg et al.'s theater metaphor of an unobtrusive social TV system [37]. In a user study, we found our participants connecting well to the on-screen silhouettes, while their television watching experience was perceived more enjoyable. We also report viewers' body movement behavior in the presence of on-screen silhouettes, which we characterize numerically with new measures (e.g., average body movement) and we report experimental findings; e.g., we found that the number of silhouettes influences viewers' body movements and the body postures they adopt and that women produce more body movement than men.
