Single Tap Hierarchy-Structured Zoom as Interface for Interactive Indoor Wayfinding Map for Elderly Users

The aim of this research is to design a simplified and acceptable interface for an indoor wayfinding map for elderly users. This research proposes a single-tap, zooming user interface using a hierarchy-structured zoom that integrates the operation of re-center zoom and a non-predefined hierarchy-structured map. Simulated maps and interfaces were built to test user acceptance.
