Estimating water storage changes and sink terms in Volta Basin from satellite missions

Water Science and Engineering, 2014
The insufficiency of distributed in situ hydrological measurements is a major challenge for hydrological studies in many regions of the world. Satellite missions such as the Gravity Recovery and Climate Experiment (GRACE) and the Tropical Rainfall ...

2D Virtual Reality-Based Exercise Improves Spatial Navigation in Institutionalized Non-robust Older Persons: A Preliminary Data Report of a Single-Blind, Randomized, and Controlled Study

Frontiers in Neurology, 2021
Background: Spatial navigation is a prodromal dementia marker. Exercise used alongside virtual reality improves many cognitive functions, but effects on spatial navigation are still unclear.Objective: To investigate the effect of virtual reality-based ...

Spatial frameworks in imagined navigation [PDF]

Psychonomic Bulletin & Review, 2006
The spatial framework model proposes that people use the extensions of their body axes as a reference frame for encoding spatial layouts in memory, and that the physical and functional properties of our bodies and the world determine the accessibility of egocentric locations from memory representations.

Maladaptive bias for extrahippocampal navigation strategies in aging humans. [PDF]

, 2013
Efficient spatial navigation requires not only accurate spatial knowledge but also the selection of appropriate strategies. Using a novel paradigm that allowed us to distinguish between beacon, associative cue, and place strategies, we investigated the ...

Indoor Scene Intelligent Identification System Based on Spatial Topological Relationship Constraints [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences
Indoor scene identification can provide prior environmental information for indoor positioning applications, achieving positioning enhancement. Due to the similarity of wireless signals in adjacent spaces, it can lead to incorrect identification in ...

How does navigation system behavior influence human behavior?

Cognitive Research, 2019
Navigation systems are ubiquitous tools to assist wayfinders of the mobile information society with various navigational tasks. Whenever such systems assist with self-localization and path planning, they reduce human effort for navigating.

Spatial Memory in Insect Navigation [PDF]

Current Biology, 2013
A wide variety of insects use spatial memories in behaviours like holding a position in air or flowing water, in returning to a place of safety, and in foraging. The Hymenoptera, in particular, have evolved life-histories requiring reliable spatial memories to support the task of provisioning their young.

Easy rider: monkeys learn to drive a wheelchair to navigate through a complex maze. [PDF]

PLoS ONE, 2014
The neurological bases of spatial navigation are mainly investigated in rodents and seldom in primates. The few studies led on spatial navigation in both human and non-human primates are performed in virtual, not in real environments.

Virtual reality in neurologic rehabilitation of spatial disorientation

Journal of NeuroEngineering and Rehabilitation, 2013
Background Topographical disorientation (TD) is a severe and persistent impairment of spatial orientation and navigation in familiar as well as new environments and a common consequence of brain damage.

Successful wayfinding in age: A scoping review on spatial navigation training in healthy older adults

Frontiers in Psychology, 2022
IntroductionSpatial navigation is a complex cognitive function that declines in older age. Finding one’s way around in familiar and new environments is crucial to live and function independently.
