This is not the way: global directional cues do not improve spatial learning in an immersive virtual environment

Cognitive Research
Spatial navigation relies on extracting environmental information to determine where to go. To support navigation behavior, navigational aids, such as maps, compasses, or global positioning systems (GPSs), offer access to easily extractible information ...

Navigation without localisation: reliable teach and repeat based on the convergence theorem

, 2018
We present a novel concept for teach-and-repeat visual navigation. The proposed concept is based on a mathematical model, which indicates that in teach-and-repeat navigation scenarios, mobile robots do not need to perform explicit localisation.

Routing Unmanned Vehicles in GPS-Denied Environments

, 2017
Most of the routing algorithms for unmanned vehicles, that arise in data gathering and monitoring applications in the literature, rely on the Global Positioning System (GPS) information for localization.

Hippocampus and retrosplenial cortex combine path integration signals for successful navigation [PDF]

, 2013
The current study used fMRI in humans to examine goal-directed navigation in an open field environment. We designed a task that required participants to encode survey-level spatial information and subsequently navigate to a goal location in either first ...
