Query: SyncUp: Vision-based Practice Support for Synchronized Dancing   The beauty of synchronized dancing lies in the synchronization of body
movements among multiple dancers. While dancers utilize camera recordings for
their practice, standard video interfaces do not efficiently support their
activities of identifying segments where they are not well synchronized. This
thus fails to close a tight loop of an iterative practice process (i.e.,
capturing a practice, reviewing the video, and practicing again). We present
SyncUp, a system that provides multiple interactive visualizations to support
the practice of synchronized dancing and liberate users from manual inspection
of recorded practice videos. By analyzing videos uploaded by users, SyncUp
quantifies two aspects of synchronization in dancing: pose similarity among
multiple dancers and temporal alignment of their movements. The system then
highlights which body parts and which portions of the dance routine require
further practice to achieve better synchronization. The results of our system
evaluations show that our pose similarity estimation and temporal alignment
predictions were correlated well with human ratings. Participants in our
qualitative user evaluation expressed the benefits and its potential use of
SyncUp, confirming that it would enable quick iterative practice.
