Finding the Optimal Visual Interface for Assisting Navigation In Multilevel Indoor Spaces

1. Finding the Optimal Visual Interface for Assisting Navigation In Multilevel Indoor Spaces Based to the early stage work of the NSF Project NSF grant No. IIS-0916219 : Information integration and human interaction for indoor and outdoor spaces Hengshan Li Advisor: Nicholas A. Giudice Department of Spatial Information Science and Engineering University of Maine

2. 1 Goal of the grant project • The primary goal of grant project is to provide a unified informatic framework for static and dynamic indoor and outdoor spaces that supports seamless human navigation tasks in built indoor and outdoor environments. Indoor Space Outdoor Space Unified Informatic Framework

3. 2 Motivation of my research • What is the optimal visual interface for assisting navigation in multilevel indoor spaces?

4. 3 Available navigation maps Outdoor 2D map Indoor 2D map Indoor 3D map Outdoor 3D map

5. 4 My research questions • Does a high fidelity simulation model make sense? • high fidelity simulation model (HM), low fidelity simulation model (LM), wireframe model (WM) and sparse model (SM). The four types of models represent a clear progression of decreasing visual granularity, what we call “simulation fidelity”. LM HM SM WM

6. 4 My research questions • Which viewing perspective should be used to best support your navigation? • First Person • Third Person (bird’s-eye view) Third Person First Person

7. 4 My research questions • Should we choose a heading-up (track up) viewing perspective or a north-up viewing perspective? • Heading-up: which means that the information displayed on the PDAs will synchronize with your orientation. • North-up, which means that the information on the PDA always remains in a north-up orientation. Heading up North up
