WYFIWYG: Investigating Effective User Support in Aerial Videography
This work addresses the need for more intuitive and effective user support in aerial videography for filmmakers, representing an incremental improvement by building on prior trajectory design tools.
The paper tackled the problem of making complex aerial videography accessible to single videographers by proposing WYFIWYG, a quadrotor camera tool that allows designing videos via frame specification, scene exploration, and continuous target framing, resulting in a user study evaluating end-user workflows with current tools.
Tools for quadrotor trajectory design have enabled single videographers to create complex aerial video shots that previously required dedicated hardware and several operators. We build on this prior work by studying film-maker's working practices which informed a system design that brings expert workflows closer to end-users. For this purpose, we propose WYFIWYG, a new quadrotor camera tool which (i) allows to design a video solely via specifying its frames, (ii) encourages the exploration of the scene prior to filming and (iii) allows to continuously frame a camera target according to compositional intentions. Furthermore, we propose extensions to an existing algorithm, generating more intuitive angular camera motions and producing spatially and temporally smooth trajectories. Finally, we conduct a user study where we evaluate how end-users work with current videography tools. We conclude by summarizing the findings of work as implications for the design of UIs and algorithms of quadrotor camera tools.
