Coordinating perspective-taking effectively
in remote or virtual settings is the prerequisite to engage in
monitoring and controlling tasks at a distance. My dissertation
examines the principles of perspective-taking to control
multiple views in remote observation tasks. A framework for
this coordination of views is introduced as a new model for
perspective-taking. In its essence, the model illustrates how
in-scene views in coordination with distant overviews, also
known as long shots, form the basis for acquiring understanding
of activities on a stage that is explored from a remote or
virtual camera, situated inside the stage under observation.
This model forms the framework for a three-dimensional view
control interface concept.
Better view control should result in better
interpretation of spatial scenes – a prerequisite for
more effective intervention into activities on remote stages.
The findings help designers identify required views to be
provided in the design of spatial control interfaces to support
perspective-taking by practitioners. The proposed improved view
control architecture is the result of the implementation of
conditions for ecological observations into the setting and
display of views into remote and virtual environments.
