TLDR
The overall project design and architecture of the NAVIG system is presented and details of a new type of detection and localization device are presented that combines a bio-inspired vision system that can recognize and locate objects very quickly and a 3D sound rendering system that is able to perceptually position a sound at the location of the recognized object.Citations

Interactivity Improves Usability of Geographic Maps for Visually Impaired People
TL;DR: A comparison of usability of a classical raised-line map versus an interactive map composed of a multitouch screen, a raised- line overlay, and audio output shows that interactive maps are a good solution for improving map exploration and cognitive mapping in visually impaired people.

Virtual Navigation for Blind People: Building Sequential Representations of the Real-World
TL;DR: Two smartphone-based virtual navigation interfaces are presented: VirtualLeap, which allows the user to jump through a sequence of street intersection labels, turn-by-turn instructions and POIs along the route; and VirtualWalk, which simulates variable speed step-by -step walking using audio effects, whilst conveying similar route information.

Good features to track
Jianbo Shi,Tomasi +1 more
TL;DR: A feature selection criterion that is optimal by construction because it is based on how the tracker works, and a feature monitoring method that can detect occlusions, disocclusions, and features that do not correspond to points in the world are proposed.

Speed of processing in the human visual system.
TL;DR: The visual processing needed to perform this highly demanding task can be achieved in under 150 ms, and ERP analysis revealed a frontal negativity specific to no-go trials that develops roughly 150 ms after stimulus onset.
