  Visualization requirements in Forensic Lucid have to do with different levels
of case knowledge abstraction, representation, aggregation, as well as the
operational aspects as the final long-term goal of this proposal. It
encompasses anything from the finer detailed representation of hierarchical
contexts to Forensic Lucid programs, to the documented evidence and its
management, its linkage to programs, to evaluation, and to the management of
GIPSY software networks. This includes an ability to arbitrarily switch between
those views combined with usable multimodal interaction. The purpose is to
determine how the findings can be applied to Forensic Lucid and investigation
case management. It is also natural to want a convenient and usable evidence
visualization, its semantic linkage and the reasoning machinery for it. Thus,
we propose a scalable management, visualization, and evaluation of digital
evidence using the modified interactive 3D documentary system - Illimitable
Space System - (ISS) to represent, semantically link, and provide a usable
interface to digital investigators that is navigable via different multimodal
interaction techniques using Computer Vision techniques including gestures, as
well as eye-gaze and audio.
