Authoring tools routinely include a timeline representation to allow the author to specify the sequence of animations and interactions. However, traditional static timelines are best suited for static, linear sequences (such MIDI sequencers) and do not lend themselves to interactive content. This forces authors to supplement their timelines with scripted actions which are not represented. Timelines also force frame-accuracy on the author, which interferes with rapid explora-tion of different designs. We present a redesign of the time-line in which users can specify the relative ordering and cau-sality of events without specifying exact times or durations. This effectively enables users to “work rough” in time. We then implement a prototype and perform a user study to in-vestigate its efficiency.
