IGROUP PRESENCE QUESTIONNAIRE (IPQ)
The Igroup Presence Questionnaire (IPQ) is a scale for measuring the sense of presence experienced in a virtual environment (VE). It has been constructed using a large pool of items and two survey waves with approximately 500 participants. It was originally constructed in German, but is now also available in English and Dutch.

The project explored how an Augmented Reality (AR) desktop environment
can integrate the standard 2D computer desktop into an augmented 3D space.
The underlying physical space is given by the standard office desk used
in everyday work. Instead of sitting only in front of a computer screen,
the user wears a video-through head mounted displays and interacts with
the environment in both tangible and virtual ways. In this augmented environment,
standard 2D application windows are attached to physical clipboards and
can be freely positioned in the working space by simply moving the clipboard.
Additionally, 3D content can be brought into and manipulated within the
same space. To support interaction with 3D content we experimented with
a circular platform, on which a 3D model can be placed, and which the
user can turn in a natural tangible way. By fusing familiar desktop utensils,
two-dimensional computer desktop applications, and three-dimensional models,
we provide a seamless transition from the traditional 2D computer desktop
to a 3D augmented working environment.
- providing 3D content and interaction in a desktop environment by integration of VR technology
- providing 2D content and interaction in a fairly large working space
- inclusion of the standard desktop environment, without substitution of 2D workflow
- seamless integration of real world, 2D computer world, and 3D (VR) world, and
- natural, intuitive, and consistent interaction techniques within the three domains.
- uses popular (modified) ARToolKit library
- 3D product evaluation
- VR research and development
- rapid prototyping and digital mockup
- interface evaluation (3D User Interfaces - 3DUI)
