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