Cognitive technologies for establishing, sharing and comparing perspectives on video over computer networks

Authors: Roy Pea, Robb Lindgren & Joseph Rosen
Institutions: Stanford University

Abstract: The rapidly increasing presence of digital video recordings and new
communication capacities on the Internet has created new possibilities for collaboration in
behavioral science research. Unfortunately, digital video has so far proven to be an
unnatural medium for collaborative activity due to a lack of adequate tools that support
joint analysis of a shared video record. We describe seven socio-technical design challenges
that face what we term computer-supported collaborative video analysis. We also
describe a software environment that we have created called DIVER that was designed to
address these challenges and provide a platform for the fluid exchange of video data as well
as the insights that the data elicit. The affordances of DIVER for supporting collaboration
around video are grounded in the descriptions of two academic contexts in which the software
played a central role in the group’s video-based activities. The potential of DIVER to serve
as a ‘cognitive technology’ is discussed.
