Given the ease that humans have with using a keyboard and mouse in typical, non-colocated computer interaction, many studies have investigated the value of co-locating the visual field and motor workspaces using immersive display modalities...
A Physics-driven Neural Networks-based Simulation System (PhyNNeSS) for multimodal interactive virtual environments involving nonlinear deformable objects [0.03%]
一种基于物理驱动神经网络的模拟系统（PhyNNeSS），用于涉及非线性可变形物体的多模态交互虚拟环境

BACKGROUND: While an update rate of 30 Hz is considered adequate for real time graphics, a much higher update rate of about 1 kHz is necessary for haptics. Physics-based modeling of deformable objects, especially when large nonlinear deform...
Lessons about Virtual-Environment Software Systems from 20 years of VE building [0.03%]
二十年的虚拟环境构建经验给虚拟环境软件系统带来的启示

What are desirable and undesirable features of virtual-environment (VE) software architectures? What should be present (and absent) from such systems if they are to be optimally useful? How should they be structured? To help answer these qu...

Image quality issues such as field of view (FOV) and resolution are important for evaluating "presence" and simulator sickness (SS) in virtual environments (VEs). This research examined effects on postural stability of varying FOV, image re...
Perceived orientation in physical and virtual environments: changes in perceived orientation as a function of idiothetic information available [0.03%]

Two experiments examined perceived spatial orientation in a small environment as a function of experiencing that environment under three conditions: real-world, desktop-display (DD), and head-mounted display (HMD). Across the three conditio...

For entertainment applications, a successful virtual experience based on a head-mounted display (HMD) needs to overcome some or all of the following problems: entering a virtual world is a jarring experience, people do not naturally turn th...
Localization of a time-delayed, monocular virtual object superimposed on a real environment [0.03%]
单目时滞虚拟物体在真实环境中的定位

Observers adjusted a pointer to match the depicted distance of a monocular virtual object viewed in a see-through, head-mounted display. Distance information was available through motion parallax produced as the observers rocked side to sid...

The question of whether the sense of presence in virtual environments (or telepresence with respect to teleoperator systems) is causally related to task performance remains un-answered because the appropriate studies have yet to be carried ...

Virtual reality technology is now being used to provide exposure and desensitization for a number of phobic conditions. In this paper, we first review these current applications and discuss the work needed to refine and expand these applica...
