A fog screen that could allow for virtual reality rooms reminiscent of Star Trek’s holodeck is going on display in a Finnish museum, after which it will become commercially available.



Called Walk-thru Virtual Environment, the screen is a physically penetrable fog on which images are projected to produce interactive displays.



Created by researchers Ismo Rakkolainen and Karri Palovuori from Tampere University of Technology, WAVE uses a steady airflow containing a thin layer of dry ice or liquid nitrogen vapour.




Images can be projected on the screen, which can be made either translucent or opaque, from the front or back, allowing for realistic displays of such things as swift rapids or brick walls similar to those on the fictional holodeck.
