Abstract

We propose a local orientation and navigation framework based on visual features that provide location recognition, context augmentation, and viewer localization information to a human user. Mosaics are used to map local areas to ease user navigation through streets and hallways, by providing a wider field of view (FOV) and the inclusion of more decisive features. Within the mosaics, we extract "visual noun" features. We consider 3 types of visual noun features: signage, visual-text, and visual-icons that we propose as a low-cost method for augmenting environments.
