On the evening of July 21st, Marshall mentioned this technology, along with other advanced concept research that he has been involved with, during his interview with Joshua P. Warren of the "Speaking of Strange" nationally syndicated radio program http://www.speakingofstrange.com/
Marshall states that there are notable differences between what is seen in the film and the real thing. For one, there is no massive technological platform. In fact, the version for use in space is small and consists of a head piece and small box, about the size of a smart phone. The head piece has earned the technology the nick name of "Holo-Deck in a Helmet", after the famous holo-decks in the TV series, Star Trek: The Next Generation. Also, there is no "medical implant", or any other kind of injection or substance, consumed.
At the Mars Society Conference, Marshall will have a basic preliminary model that will not feature the full effect, but will be an example of the technology that was used to get to where he is now for use during long space journeys or as stress relief while on the Martian surface. Marshall plans on making his technology available for use during the MarsOne project, that intends on sending a manned crew to Mars in 2023. He plans on launching his own version of the Rekall centers, seen in the movie, by 2015. He'll begin testing the technology on volunteers beginning next year.
