增强现实环境中的临场感测量:问卷设计与初步测试

Measuring Presence in Augmented Reality Environments: Design and a First Test of a Questionnaire

Holger Regenbrecht, Thomas Schubert

摘要:

增强现实(AR)通过利用特殊显示技术添加空间对齐的虚拟对象(3D模型、2D纹理、文本注释等)来丰富用户的真实环境。它们要么戴在身上,要么放在工作环境中。从技术的角度来看,AR面临着三个主要挑战:(1)生成高质量的渲染,(2)精确地将虚拟对象(VO)与真实环境(在位置和方向上)配准,以及(3)以交互式实时方式进行(Regenbrecht,Wagner和Baratoff,2002)。我们的目标是创造一种印象,即VO是真实环境的一部分。因此,类似于虚拟现实的定义(Steuer,1992),从心理学的角度来定义AR是有意义的:增强现实传达了VO存在于真实环境中的印象。为了评估这一目标的实现程度,有必要对这种存在进行心理测量。在下文中,我们将描述AR系统的技术特征,这些技术特征使得特殊问卷版本成为必要,描述我们的问卷开发方法和数据汇集策略。最后,我们将介绍在最近的一项研究与385名参与者的问卷调查的应用的第一个结果。

英文摘要:

Augmented Reality (AR) enriches a user's real environment by adding spatially aligned virtual objects (3D models, 2D textures, textual annotations, etc) by means of special display technologies. These are either worn on the body or placed in the working environment. From a technical point of view, AR faces three major challenges: (1) to generate a high quality rendering, (2) to precisely register (in position and orientation) the virtual objects (VOs) with the real environment, and (3) to do so in interactive real-time (Regenbrecht, Wagner, and Baratoff, 2002). The goal is to create the impression that the VOs are part of the real environment. Therefore, and similar to definitions of virtual reality (Steuer, 1992), it makes sense to define AR from a psychological point of view: Augmented Reality conveys the impression that VOs are present in the real environment. In order to evaluate how well this goal is reached, a psychological measurement of this type of presence is necessary. In the following, we will describe technological features of AR systems that make a special questionnaire version necessary, describe our approach to the questionnaire development, and the data collection strategy. Finally we will present first results of the application of the questionnaire in a recent study with 385 participants.
