Our first problem was to find suitable hardware,
that is see-through goggles.
Searching the Internet gave us the name of a relatively nearby
company, Cyber Mind NL,
that specialized in entertainment VR solutions.
Both price-wise and in terms of functionality semi-transparent
see-through glasses appeared to be no option,
so instead we chose for simple LCD-projection goggles
with a (head-mounted) low-resolution camera.
This solution also meant that we did not need
expensive head orientation tracking equipment,
since we could, in principle, determine focus using
captured image analysis solutions such as provided by the AR Toolkit.
Moreover, captured video feed ensured the
continuity and reactiveness needed for
a true (first-person perspective) VR experience.
