A Virtual Laboratory on satellite-based navigation

Control Engineering Practice, 2001
A primary objective in the development of a navigation system is to test the effectiveness of its algorithms together with their capability of operating in real time. With this in mind a Virtual Laboratory capable of simulating the main features of general aviation aircraft navigational sensors together with their interface to the on-board computer has

Navigating Virtual Teamwork

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.

Virtual bronchoscopic navigation system shortens the examination time—Feasibility study of virtual bronchoscopic navigation system

Lung Cancer, 2007
Computed tomography (CT)-guided transbronchial biopsy (TBB) using an ultrathin bronchoscope with simulation by virtual bronchoscopy (VB) is effective for diagnosing small peripheral pulmonary lesions. However, we occasionally lose the proper bronchi to the lesion when a bronchoscope is inserted into peripheral bronchi with severe rotation.

Virtual reality navigation system in virtual mall environment

Proceedings of the 3rd International Conference on Communication and Information Processing, 2017
The mall is a shopping center that contains a variety of retail stores and typically also restaurants or movie theater. Therefore, the building has large size and sometimes made people get confused to find a place or destination at the mall. The existing solution to this problem is to provide navigation in the mall such as directions, information ...

Navigation modes in virtual environments

Proceedings of the 5th symposium on Applied perception in graphics and visualization, 2008
There is considerable evidence that people have difficulty maintaining orientation in virtual environments. This difficulty is usually attributed to poor idiothetic cues, such as the absence of proprioception and other sources of information provided by self locomotion.

Virtual Clones: Data-Driven Social Navigation

2011
Millions of participants inhabit online virtual worlds such as SL and engage in a wide range of activities, some of which require the performance of tedious tasks. Our goal is to develop a virtual proxy that would replace human participants in online virtual worlds. The proxy should be able to perform simple tasks on behalf of its owner, similar to the

Hyper-navigation in virtual buildings

Proceedings of IEEE Virtual Reality Annual International Symposium, 2002
The virtual reality (VR) user interface style allows the user to manipulate virtual objects in a 3D environment. A software architecture which guides users in virtual worlds is introduced. The architecture is based on the concept of task-oriented agents which support users in acting within a virtual environment (VE).

Constructing virtual mines for navigation

1997 IEEE International Conference on Systems, Man, and Cybernetics. Computational Cybernetics and Simulation, 2002
This article presents an underground mine model created to study such tasks as autonomous navigation, obstacle avoidance, exploration and surveying, or place recognition. We first describe the generic object model upon which the mine model is based, and then describe the mine model itself.

Slice-based virtual endoscopy navigation

Proceedings Fifth International Conference on Information Visualisation, 2002
Navigation path planning is a crucial part of virtual endoscopy, but the identification of the optimal fly-through path is a time-intensive process. This paper describes a prototype system for virtual endoscopy and proposes a slice-based approach to calculating the path of the virtual camera that uses the slice borderlines of region-of-interest images ...

Navigation Training in Virtual Environments

International Journal of Cognitive Ergonomics, 2001
Virtual environments (VE) promise important opportunities as future interfaces to computational systems, especially where such technology can take advantage of strong human visuospatial capabilities. Although such synthetic environments often project homeomorphic physical representations of real-world layouts, it is not known how individuals develop ...
