Abstract: Hargood, Charlie Green, DanielAuthoring tools, the software used to create, edit, and develop Interactive Digital Narrative (IDN), are a critical part of both IDN authorship and research. These tools, their features, interface paradigmsInterface paradigm, visualisations, and user experienceUser experience (UX) (UX) can impact the authoring process and the resulting works, and consequently must inform our wider understanding of IDN context. While IDN research has widely explored data models for authoring tools, feature sets, and demonstrated a variety of developed tools for a range of IDN forms, it has done comparatively very little to evaluateEvaluation(evaluate) and study the UXUser experience (UX) of these tools and their impact on authors and their works. In this chapter, we survey the existing work on authoring tools and explore the scale of this problem, the reasons for it, how the communityCommunities has documented this issue, and how we might begin to tackle it. We conclude that the existing methods for the study of UXUser experience (UX) are poorly suited for the study of authoring tools, and that as well as making the study of tool UXUser experience (UX) a priority, we must also develop new methods of evaluationEvaluation.
