Navigating mazes in a virtual environment
SPIE Proceedings, 2003In this research we are concerned with computer interfaces with which subjects navigate through maze simulations which are essentially buildings, with corridors and intersections, such as frequently encountered in computer games and simulations. We wish to determine if virtual reality interfaces introduce a performance enhancement that might be ...

Hyper-navigation in virtual buildings
Proceedings of IEEE Virtual Reality Annual International Symposium, 2002The 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).

Virtual Bronchoscopic Navigation
Clinics in Chest Medicine, 2010Virtual bronchoscopic navigation (VBN) is a method for the guidance of a bronchoscope to peripheral lesions using virtual bronchoscopy (VB) images of the bronchial path. Irrespective of the bronchoscopist's skill level, the bronchoscope can be readily guided to the target in a short time.

A toolset for navigation in virtual environments
Proceedings of the 6th annual ACM symposium on User interface software and technology, 1993Maintaining knowledge of current position and orienta- tion is frequently a problem for people in virtual environ- ments. In this paper we present a toolset of techniques based on principles of navigation derived from real world analogs. We include a discussion of human and avian navigation behaviors and show how knowledge about them were used to ...

Efficiency of Electromagnetic Navigation Bronchoscopy and Virtual Bronchoscopic Navigation
The Annals of Thoracic Surgery, 2020Image-guided bronchoscopy techniques have emerged as a means of improving pulmonary nodule biopsy yield. However comparisons of the diagnostic efficacy of electromagnetic navigation bronchoscopy (ENB) and virtual bronchoscopic navigation (VBN) have not reached a consensus.

Navigation Maps for Virtual Travelers
2013 International Conference on Cyberworlds, 2013Navigation is one of the most fundamental tasks in virtual environments, that requires timely collision detection and collision avoidance mechanisms. It was shown that when navigation is constrained to moving on a terrain, the problem of collision detection can be reduced from 3D to 2D case, by encoding all 3D objects that constitute travel obstacles ...

Navigating large virtual spaces
International Journal of Human-Computer Interaction, 1996As important as navigation is to human performance in virtual worlds, it is an often overlooked problem in the design process. This article reports an experiment intended to show that real‐world wayfinding and environmental design principles are effective in designing virtual worlds that support skilled wayfinding behavior.

Navigating Ecosystem Virtuality
2023Addressing future challenges by means of innovation requires organizations to work together to a much larger degree than today, requiring both physical (‘colocated’) and digital collaboration. This collaboration for innovation often goes beyond single organizations and results in networks of shared value creation comprising different actors such as ...

Contributions of Proprioception to Navigation in Virtual Environments
Human Factors: The Journal of the Human Factors and Ergonomics Society, 1998Users immersed in virtual environments (VEs) are prone to disorientation and have difficulty transferring spatial knowledge to the real world. A single experiment investigated the contribution of inadequate proprioception to this problem by providing participants with interfaces to a virtual environment that either did (a walking interface) or did not (

A Virtual Laboratory on satellite-based navigation
Control Engineering Practice, 2001A 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
