增强现实（Augmented Reality， AR）通过特殊的显示技术，添加空间对齐的虚拟对象（3D模型、2D纹理、文本注释等），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。从技术角度来看，AR面临三大挑战：(1)生成高质量的渲染，(2)将虚拟对象（VOs）与真实环境精确地（在位置和方向上）注册，以及(3)在交互式实时中这样做（Regenbrecht, Wagner, & Baratoff, in press）。我们的目标是创造一种印象，即VOs是真实环境的一部分。因此，与虚拟现实的定义类似（Steuer, 1992），从心理学的角度定义AR是有意义的：增强现实传达了VOs存在于真实环境中的印象。为了评估这个目标达到的程度，有必要对这种存在进行心理测量。在下面，我们将描述AR系统的技术特点，使特殊的问卷版本成为必要，描述我们的问卷开发方法，以及数据收集策略。目前正在收集数据，结果将在研讨会上展示。
Introduction 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, & Baratoff, in press). 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 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. Data are currently collected, and results will be presented at the workshop.
