The next step, however, is to close the loop between the expert
and the user, by exploring the best way to provide feedback.
Whilst this work has shown that it is possible to encode motion
information that can be used to quantitatively analyse performances
and to use this analysis to provide feedback, there
is a huge range of possibilities of how this feedback may be.
Topics of interest in this sense include multi-modal interaction,
information architecture, semiotics, etc.
