At 2007-2008 University of Joensuu had a project VIVA - Virtual room in a therapy work with severe hospitalized children. The purpose was to bring virtual reality applications to the child at hospital, and if possible above his/her bed. In here the our exhibition package equipment was used, however during the project it was realized that normal passive-stereo version could not be used as it was not suitable to requirements of hospital room. Luckily, during the project there came first small versions of active stereo-equipment and therefore it was used instead. The project was successful, and made many children happy.
There have been some articles about this:
Unfortunately other media links have become unavailable. We hope that the link above anyway gives good picture of the project.
