Content can be repurposed, adapted and stretched across
platforms. A story can start in one medium and finish in
another. How are audiences moved between platforms, and
how can one make this traversal a part of the entertainment
experience itself? This paper provides an introduction to
multi-platform and multi-format entertainment and then
outlines the factors that influence cross-media interaction
design. What is to be considered when designing for
movement between platforms? How are audiences moved
between platforms? What influences the choice of traversal?
Critical factors will be listed, as a first step towards
developing patterns in cross-media interaction design. This
first step is a primer for part two, which will be delivered at a conference.
