  Augmented video presentation tools provide a natural way for presenters to
interact with their content, resulting in engaging experiences for remote
audiences, such as when a presenter uses hand gestures to manipulate and direct
attention to visual aids overlaid on their webcam feed. However, authoring and
customizing these presentations can be challenging, particularly when
presenting dynamic data visualization (i.e., animated charts). To this end, we
introduce VisConductor, an authoring and presentation tool that equips
presenters with the ability to configure gestures that control affect-varying
visualization animation, foreshadow visualization transitions, direct attention
to notable data points, and animate the disclosure of annotations. These
gestures are integrated into configurable widgets, allowing presenters to
trigger content transformations by executing gestures within widget boundaries,
with feedback visible only to them. Altogether, our palette of widgets provides
a level of flexibility appropriate for improvisational presentations and ad-hoc
content transformations, such as when responding to audience engagement. To
evaluate VisConductor, we conducted two studies focusing on presenters (N = 11)
and audience members (N = 11). Our findings indicate that our approach taken
with VisConductor can facilitate interactive and engaging remote presentations
with dynamic visual aids. Reflecting on our findings, we also offer insights to
inform the future of augmented video presentation tools.
