Elaborate Descriptive Information in Indoor Route Instructions


The following paper presents the enhancement of indoor route instructions with descriptive generation strategies. We consider the latter to be highly important for the quality and helpfulness of automatically generated indoor route instructions. We conducted an experiment showing that participants receiving route instructions enriched with elaborate descriptive information instead of step-by-step procedural information for crucial route segments performed better in objective and subjective measures than those receiving only basic prescriptive route instructions. Based on the gained knowledge, we conclude that descriptive strategies are an important part of indoor route instructions and should be actively considered in system development.
