Adaptive navigation assistance based on eye movement features in virtual reality
Virtual Reality & Intelligent Hardware, 2023 Background: Navigation assistance is very important for users when roaming in virtual reality scenes, however, the traditional navigation method requires users to manually request a map for viewing, which leads to low immersion and poor user experience ...

Low-frequency theta oscillations in the human hippocampus during real-world and virtual navigation
Nature Communications, 2017 Low-Frequency Oscillations (LFO) in the range of 7–9 Hz, or theta rhythm, has been recorded in rodents ambulating in the real world. However, intra-hippocampus EEG recordings during virtual navigation in humans have consistently reported LFO that appear ...

The Whole Ship Simulation Training Platform Based on Virtual Reality
IEEE Open Journal of Intelligent Transportation Systems, 2021 The students generally lack the overall grasp about navigation and the operation practice of equipment and instruments on board under the current education mode. The simulator based on virtual reality has become an important way in learning and training.

Navigating virtual agents in online virtual worlds [PDF]
Proceedings of the 13th international symposium on 3D web technology, 2008 We present an approach for navigating autonomous virtual agents in online virtual worlds that are based on a centralized server network topology. Each agent's motion is controlled through local and global navigation. Our local navigation model is based on artificial social forces that has been extended to account for inaccurate sensing from network ...

Adaptive navigation for virtual environments [PDF]
2014 IEEE Symposium on 3D User Interfaces (3DUI), 2014 Navigation speed for most navigation interfaces is still determined by rate-control devices (e.g. joystick). The interface designer is in charge of adjusting the range of optimal speeds according to the scale of the environment and the desired user experience. However, this approach is not valid for complex environments (e.g. multi-scale environments).

International Journal of Applied Earth Observations and Geoinformation, 2021 Large-scale crowd evacuation simulation in virtual reality is of great significance for emergency response. However, the existing large-scale crowd evacuation simulation methods are challenging to apply to the virtual reality scene.
