A mask over your face = Virtual Reality has been the accepted definition for like three decades. I remember seeing the same VR concepts like in 1992-94:
This concept has been part of pop culture, in movies, sci-fi novels, and tried by various different companies for years.
It's called the HOLODECK in Star Trek, not the Virtual Reality Deck, because that's a completely different concept.
That's like saying Nintendo is falsely advertising the 3DS because the images aren't literally coming out of the screen in three dimensions.
