概括
视频通过体现 (PTE) 提供了一种无硬件的方式来增强虚拟现实 (VR) 的存在. 这种新的方法在VR中代表了用户的真实身体,在没有额外的设备的情况下改善了实施方式.
科学领域:
- 虚拟现实 (VR) 和人机交互 (HCI)
- 计算机图形和可视化
背景情况:
- 在虚拟现实 (VR) 中提升用户体验往往依赖于通过个性化化象征的自我表现.
- 现有的avatar方法通常需要外部硬件,并专注于手表达.
- 需要更容易访问和独立于硬件的方法来实现用户在VR中的实施例.
研究的目的:
- 引入和评估视频通过体现 (PTE) 作为一种替代VR中传统的基于化身的自我表现.
- 评估PTE对用户存在,体现,任务执行和认知负载的影响.
- 确定PTE是否为VR实施方案提供了实际和高效的解决方案,而不需要额外的硬件.
主要方法:
- 开发了PTE,使用头戴显示器 (HMD) 的实时深度图来细分和表示用户在VR中的身体.
- 进行了40名参与者进行座位对象排序任务的跨主体研究.
- 比较了 PTE 和一个定制的化身条件之间的用户体验指标.
主要成果:
- 与定制化身相比,PTE显著增强了用户的存在感和体现.
- 尽管由于深度分辨率造成了轻微的视觉缺陷,但PTE并没有对任务性能或认知负载产生负面影响.
- 对于PTE条件,没有报告VR疾病的增加.
结论:

First Pass Effect
5.0K
Presystemic elimination, or the first-pass effect, is the metabolism of drugs that reduces their effective concentration at the site of action. Apart from the first-pass effect, the systemic bioavailability of the drug is also reduced by other factors, including incomplete absorption or chemical degradation of drugs.
Depending on the route of administration, drugs can be metabolized in the liver, intestine, lungs, and vasculature. Orally administered drugs are first absorbed through the...

Facial Feedback Hypothesis
108
Charles Darwin proposed that facial expressions are an evolutionary adaptation for communication. He argued that these expressions are not influenced by culture but are universal across species. For example, a snarling expression with exposed teeth signals a threat in many animals, including humans. Darwin also suggested that displaying an emotion can intensify the feeling. Smiling, for example, could enhance one's sense of happiness. This idea laid the foundation for understanding the role...

Virtual Work
775
The principle of virtual work states that if a body is in static and dynamic equilibrium, then the sum of all the virtual work done by all external forces and couple moments for any given virtual displacement must be zero.
In static equilibrium, a body can experience an imaginary or virtual movement, such as displacement or rotation. The virtual work done by a force is equal to the dot product of force and virtual displacement in the direction of the force. When it comes to virtually rotating a...
