Building authoring environments for constraint-based inter- active narratives (sculptural hypertexts) is challenging, as dealing di- rectly with functions and variables is alien to many authors and requires them to think at a lower level than story structure. We propose an ap- proach that uses higher level constructs based on common structural patterns, which are then translated behind the scenes into a set of con- straints for a sculptural engine. We present the StoryPlaces authoring tool that applies this idea with the patterns of Locking and Phasing and allows for the creation of constraint-based locative hypertext ction. Our work shows how the poetics of interactive narratives can be used in the software design process to create more accessible authoring tools
