subject's hands using infrared light. Two demos, which at the
time were state-of-the-art in freely available consumer VR
experiences (i.e., Sightline: The Chair and Blocks), were then
shown. These VR experiences were also available for other
devices, e.g., the HTC Vive (a video of the experimental
setup is available at https://vimeo.com/231053767). As the
two demos differed from each other in their modes of interaction, they were well suited as a control variable for different
levels of immersion in VR.
Sightline: The chair allowed for the user to move through
different VR scenes at a fast pace. These scenes (e.g., streetlevel landscapes, woodlands, expansive spaces, or a construction site) helped the user to achieve presence within the virtual
environment. The demo also introduced an unconventional
control scheme: it was the user's sight (head rotation) that
determined the demo's progress. Sightline encouraged users to
look around with full head movements, which simultaneously
propelled the direction of the demo forward (Figure 1).
Blocks made use of the Leap Motion controller. During
the course of the demos, one of the user's tasks was to follow
the instructions of a small robot that incrementally taught the
user various ways of manipulating and producing virtual
blocks (e.g., moving and grabbing blocks, creating blocks
from nothing, or turning gravity on and off). The demo pre-

way with virtual objects (Figure 2).

The qualitative approach allows for a more detailed understanding of a subject's perceptions and experiences during
their initial encounter with a VR world. As compared to statistical data, qualitative findings will show not only if, but
most importantly how, presence and interaction are perceived
in VR. Qualitative research makes the assertion that what is
