概括
虚拟现实 (VR) 中的双任务干扰受任务模式和负载的影响. 多模式接口可以减少当任务共享不同的感知模式时的性能下降,特别是在高工作负载条件下.
科学领域:
- 人与计算机的交互
- 认知心理学 认知心理学
- 虚拟现实 虚拟现实 虚拟现实
背景情况:
- 双任务干扰是一种已知的现象,即同时执行两个任务会降低性能.
- 感知模式和任务负载是影响双任务干扰的既定因素.
- 这些因素在沉浸式虚拟现实 (VR) 环境中的相互作用仍未得到充分探索.
研究的目的:
- 研究任务模式 (视觉,听觉),任务负载水平和任务负载类型对VR中双任务干扰的影响.
- 检查目标干扰器相似性和显示速度在双重任务期间如何影响性能下降.
- 了解沉浸式虚拟环境中任务特征和双重任务成本之间的相互作用.
主要方法:
- 参与者从事视觉跟踪和视觉/听觉检测任务,无论是单独还是同时在VR.
- 实验1操纵了跟踪任务负载 (目标-干扰器相似性) 和检测任务负载 (显示率).
- 实验2通过目标分散器相似性操纵检测任务负载.
主要成果:
- 增加的检测任务负载在检测任务中显著增加了双重任务成本 (DTC),无论其模式如何.
- 追踪任务DTC不受增加的追踪任务负载的影响.
- 在视觉检测任务中,更高的检测任务负载导致了更高的DTC,但不是在听觉任务中.
结论:
- 分享相同感知模式的任务可能会经历加剧的双任务干扰.
- 干扰的程度取决于特定的任务负载级别和遇到的类型.
- 这些发现可以指导高工作负载场景的有效多式联网接口的设计.

Stress: General Loading Conditions
743
To grasp the intricacy of real-world conditions where multiple loads are applied simultaneously to a structure, one might visualize a section passing through a specific point within a body, aligned parallel to the xy plane. This section is subjected to various forces, including original loads, normal forces, and shearing forces.
The shearing force, possessing potential directionality within the plane of the section, is simplified into two component forces running parallel to the x and y axes....

High-Level and Low-Level Awareness

Controlled processes in human consciousness represent high-alert mental states where individuals deliberately focus their attention on achieving specific goals. Controlled processes can be seen in situations like mastering new technology, where a person might become so absorbed that they ignore surrounding distractions. Such processes involve selective attention, requiring one to concentrate on particular elements of experience while disregarding others. These are governed by executive...
