Abstract

We studied an indoor wayfinding application for individuals with cognitive impairments using Wizard-of-Oz techniques. This gave us insights into the technological considerations for the location system underlying such an application. We have abstracted these into generally desirable properties for location-aware systems for wayfinding. In addition to general requirements for accuracy and robustness, we discuss what other information about the environment should be provided that supports wayfinding. Our work showed that combining rich environment information with user location is key to making indoor wayfinding applications feasible
