Finding the Optimal Visual Interface for Assisting Navigation In Multilevel

Indoor Spaces

1 Goal of the grant projectThe 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.

4 My research questionsDoes 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”. HM LM

4 My research questionsWhich viewing perspective should be used to

best support your navigation?First PersonThird Person (bird’s-eye view)

First Person Third Person

4 My research questionsShould 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.
