Mediated Reality and Location Awareness to Facilitate Topographical Orientation
Notice bibliographique
Résumé
Topographical orientation is the ability to orient oneself within the environment and to\nnavigate through it to specific destinations. Topographical disorientation (TD) refers to deficits in orientation and navigation in the real environment, and is a common sequela of brain injuries. People with TD often have difficulties interacting with and perceiving the surrounding environment. The literature suggests that patients with TD are likely to benefit from research leading to clinical standards of practice and technology to facilitate\ntopographical orientation.\n In the light of the above, the objectives of this thesis were to investigate methods of realizing a context-aware, wearable mediated environment system for indoor navigation, and to develop a standard method of quantifying the impact of such a system on indoor navigation task performance.\n In realizing these objectives, we first conducted an extensive literature review of in-door localization systems. This review served to identify potential technologies for an indoor, in-situ wayfinding assistive device. Subsequently, an automated navigation algorithm was designed. Our algorithm reduced the navigational effort of simulated patients with topographical disorientation while accounting for the physical abilities of the patient, environmental barriers and dynamic building changes. We introduced and demonstrated\na novel energy-based wayfinding metric, which is independent of route complexity. An\nexperiment was conducted to identify preferred graphical navigation tools for mediated reality wayfinding guidance. Different combinations of spatial knowledge, graphical presentations and reference frames were considered in the experiment. The data suggested that the locator and minimap are the preferred navigational tools. Two unique optical-inertial localization systems for real-time indoor human tracking were created. The first localization system was oriented to pedestrians, while the second was implemented on a wheelchair. Empirical tests produced localization accuracies comparable to those reported in literature. Finally, a fully operational mediated reality location aware system for indoor navigation was realized. Tests with human participants indicated a significant\nreduction in physical effort in comparison to the no-tool condition, during wayfinding\ntasks in an unfamiliar indoor environment. Collectively, the findings and developments\nof this thesis lay the foundation for future research on wearable, location-based navigational assistance for individuals with wayfinding difficulties.
