Dmt - a Demonstration Tool

DMT is a software demonstration tool, running on workstations, that can be used to demonstrate other software tools. The paper describes the reasons for developing DMT and the implementation of DMT. DMT simulates a video recorder/player system and provides recording, winding (forward/backward) and replaying functions. During recording, DMT records the target tool window image changes and the interactions between the target tool and the controlling mouse. By deleting and inserting visual-image scripts and by adding textual comments to explain the visual-image changes, a user can obtain editing of what has been recorded. During replay, DMT shows how the target window changes as if the target tool is being demonstrated in real time. The textual comments are played synchronously with the visual images.
