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.

Augmented or mixed reality is an interesting area of research with many potential applications. However, in the course of the project we dropped our ambition to develop personalized presentations using image analysis, since we felt that the technology for doing this in a mixed reality theatre setting is simply not ripe, and instead we concentrated on using the captured video feed as the driver for text and image presentation. In addition, we developed image manipulation techniques to transform the (projection of the) captured video, to obtain more implicit effects, as to avoid the explicit semantic overload resulting from the exclusive use of text and images.
