Navigation in virtual environment by the macaque monkey
Behavioural Brain Research, 2004To determine whether monkeys can navigate a virtual environment, and whether they can represent a virtual environment in their brain, we trained two macaque monkeys to perform a navigation task in a virtual building and conducted behavioral analyses. After learning the task from the first starting point, they were trained to perform the navigation task

Virtual angioscopy and 3D navigation of the aorta
Journal of Cardiac Surgery, 2016The objective of this study is to demonstrate the applicability of virtual angioscopy (VA) in different forms of aortic disease where the diagnosis is unclear or uncertain. Five cases are presented where VA helped to establish a correct diagnosis and to choose the best surgical strategy by providing an intuitive image of the aorta.

Interactive dynamic navigation for virtual endoscopy
Computers in Biology and Medicine, 1999Complex anatomical information can be obtained from a 3D radiologic image by navigating through it in a manner similar to an endoscopic examination. Real-time computation of 'virtual' endoscopic views, however, is needed to permit interactive navigation. We present a fast volume-rendering method for computing such views.

Navigation system in a virtual environment by gestures
2012 9th International Conference on Communications (COMM), 2012In this paper we will try to present a new technique of navigation in a virtual environment using dynamic gestures performed with arms and we made a performance analysis of the navigation system. System evaluation has been made using following performance parameters: accuracy, precision and sensitivity of gesture recognition.

Representational neglect and navigation in virtual space
Cognitive Neuropsychology, 2009Previous studies have shown that mental representational disorders affect specific mechanisms that subserve human orientation. Specifically, representational neglect impairs the ability to reorient oneself in a new environment. Apparently, the inability of patients with this disorder to manipulate a mental representation of the environment prevents ...

In a post-pandemic world, the ease with which we can work in virtual settings has increased not only in the workplace but also in schools. It is important that we not only train students for working in a virtual setting individually, but also in a completely virtual environment with others.

Studying Children’s Navigation in Virtual Reality
2016Navigation in large-scale virtual environments is composed of locomotion and wayfinding. We compared two locomotion techniques in an immersive CAVE-like display in order to determine which one promotes better performance in children in a wayfinding task. A ‘treasure hunt’ game scenario was devised in which participants had to navigate to various houses

Navigating the Virtual Classroom With Virtual Reality
The COVID-19 pandemic has dramatically impacted global education, necessitating the development of more adaptable and innovative learning paradigms. Immersive technologies such as Augmented Reality (AR), Virtual Reality (VR), and Mixed Reality (MR) present substantial potential for enhancing educational experiences by making learning more interactive ...openaire +1 more source
Navigating the Virtual Landscape
This article covers online communities, their evolution, and their social impact. It explores online communities from ARPANET's late 1960s launch to the present, including wikis, MMORPGs, and virtual worlds. Virtual communities have commercial potential, but they must be built and maintained through a common identity, strong leadership, and continual ...Andi Asrifan +5 more

Evaluation of navigation interfaces in virtual environments
SPIE Proceedings, 2014When users are immersed in cave-like virtual reality systems, navigational interfaces have to be used when the size of the virtual environment becomes larger than the physical extent of the cave floor. However, using navigation interfaces, physically static users experience self-motion (visually-induced vection). As a consequence, sensorial incoherence
