This was part of the Doctoral Consortium presentation in the ICMI Conference 2019 at Suzhou, China on 14th October, 2019. Collaboration is an important skill of the 21st century. It can take place in an online (or remote) setting or in a colocated
(or face-to-face) setting. With the large scale adoption
of sensor use, studies on co-located collaboration (CC) has
gained momentum. CC takes place in physical spaces where
the group members share each other’s social and epistemic
space. This involves subtle multimodal interactions such
as gaze, gestures, speech, discourse which are complex in
nature. The aim of this PhD is to detect these interactions
and then use these insights to build an automated real-time
feedback system to facilitate co-located collaboration
