摘要

虚拟环境(VE)提供了与物理环境类似的交互方式:个人可以导航和操纵物体。然而,这些交互的前提条件是能够查看环境。尽管存在大量的场景查看技术(即促进虚拟场景视觉感知的交互技术),但却没有指导来帮助设计者选择实施哪些技术。我们借鉴认知心理学、计算机视觉以及虚拟现实(VR)应用方面的文献,根据虚拟环境中的视觉结构和任务提出了一种场景分类法。我们通过将该分类法应用于无障碍问题(即头部活动能力受限)来演示如何使用该分类法。我们利用该分类法对现有的场景浏览技术进行了分类,并生成了三种无需头部移动的新技术。在我们对 16 名参与者进行的技术评估中,我们发现参与者在设计考虑因素(如可访问性、逼真度和空间感知)方面进行了权衡,这将影响他们是否会使用这些新技术。我们的研究结果证明了场景分类法在帮助设计师推理虚拟现实交互、任务和环境之间关系方面的潜力。

A Virtual Reality Scene Taxonomy: Identifying and Designing Accessible Scene-Viewing Techniques

Virtual environments (VEs) afford similar interactions to those in physical environments: individuals can navigate and manipulate objects. Yet, a prerequisite for these interactions is being able to view the environment. Despite the existence of numerous scene-viewing techniques (i.e., interaction techniques that facilitate the visual perception of virtual scenes), there is no guidance to help designers choose which techniques to implement. We propose a scene taxonomy based on the visual structure and task within a VE by drawing on literature from cognitive psychology and computer vision, as well as virtual reality (VR) applications. We demonstrate how the taxonomy can be used by applying it to an accessibility problem, namely limited head mobility. We used the taxonomy to classify existing scene-viewing techniques and generate three new techniques that do not require head movement. In our evaluation of the techniques with 16 participants, we discovered that participants identified trade-offs in design considerations such as accessibility, realism, and spatial awareness, that would influence whether they would use the new techniques. Our results demonstrate the potential of the scene taxonomy to help designers reason about the relationships between VR interactions, tasks, and environments.

期刊介绍: This ACM Transaction seeks to be the premier archival journal in the multidisciplinary field of human-computer interaction. Since its first issue in March 1994, it has presented work of the highest scientific quality that contributes to the practice in the present and future. The primary emphasis is on results of broad application, but the journal considers original work focused on specific domains, on special requirements, on ethical issues -- the full range of design, development, and use of interactive systems.
