摘要

将空间记忆外化的一种直观方式是绘制草图。与传统的纸质草图相比,虚拟现实(VR)为研究空间记忆的三维方面创造了新的机会,因为它使用户能够直接在三维界面上表达三维信息。本研究的目标是为研究人员和不具备草图绘制专业知识的非专业用户设计一款三维草图绘制工具,使他们在完成一些三维关键任务后能够将空间信息记忆外化。目前已有使用虚拟现实技术的三维草图绘制工具,但目前的半空三维草图绘制方法存在两个问题:(1) 深度知觉错误导致草图失真;(2) 由于自由度增加和缺乏物理支持,对认知和感觉运动的要求提高。为了解决这些问题,我们开发了一种新颖的草图界面 VResin,它将三维半空草图与二维表面草图协同使用,将三维草图构建成一个逐层绘制的过程。一项由 48 名参与者参与的多层建筑场景实验研究表明,与在 VR 中进行空中草图绘制相比,VResin 支持用户绘制变形较小的草图,同时保持了草图的完整性和概括性。我们还展示了可从三维草图中获益的潜在应用,以及 VResin 对各种建筑形状的适用性。

VResin: Externalizing spatial memory into 3D sketch maps

VResin: Externalizing spatial memory into 3D sketch maps

An intuitive way to externalize spatial memory is to sketch it. Compared to traditional paper-based sketches, virtual reality (VR) creates new opportunities to investigate the 3D aspect of spatial memory as it empowers users to express 3D information on a 3D interface directly. The goal of this study is to design a 3D sketch mapping tool for researchers and non-expert users without sketching expertise that enables externalizing memories of spatial information after some 3D-critical tasks. There exist 3D sketching tools using VR, but there are two issues with the current mid-air 3D sketching approach: (1) distortion of sketches due to depth perception errors and (2) increased cognitive and sensorimotor demands due to an increased degree of freedom and absence of physical support. To address these problems, we implemented VResin, a novel sketching interface that synergizes 3D mid-air sketching with 2D surface sketching to scaffold 3D sketching into a layer-by-layer process. An experimental study with 48 participants on multi-layer building scenarios showed that VResin supports users in creating less distorted sketches while maintaining the level of completeness and generalization compared to mid-air sketching in VR. We also demonstrate the potential applications that can benefit from 3D sketch maps and the suitability of VResin for a variety of building shapes.

期刊介绍: The International Journal of Human-Computer Studies publishes original research over the whole spectrum of work relevant to the theory and practice of innovative interactive systems. The journal is inherently interdisciplinary, covering research in computing, artificial intelligence, psychology, linguistics, communication, design, engineering, and social organization, which is relevant to the design, analysis, evaluation and application of innovative interactive systems. Papers at the boundaries of these disciplines are especially welcome, as it is our view that interdisciplinary approaches are needed for producing theoretical insights in this complex area and for effective deployment of innovative technologies in concrete user communities. Research areas relevant to the journal include, but are not limited to: • Innovative interaction techniques • Multimodal interaction • Speech interaction • Graphic interaction • Natural language interaction • Interaction in mobile and embedded systems • Interface design and evaluation methodologies • Design and evaluation of innovative interactive systems • User interface prototyping and management systems • Ubiquitous computing • Wearable computers • Pervasive computing • Affective computing • Empirical studies of user behaviour • Empirical studies of programming and software engineering • Computer supported cooperative work • Computer mediated communication • Virtual reality • Mixed and augmented Reality • Intelligent user interfaces • Presence ...
