Modular virtual reality headset and virtual reality systems for use in public venues

A modular virtual reality headset for use by a user having a face and eyes, said modular virtual reality headset, comprising:

• a mask having face-contacting end and an opposing open end, said face-contacting end being sized and shaped to snuggly fit said a user's face when worn, said open end defining a first connecting rim;
• a strap attached to said mask for selectively securing said mask to said user's face;
• a viewing unit having a face-directed end and an opposing outward end, said viewing unit including a display for showing video content, a lens, and controlling circuitry, said lens being positioned between said display and said face-directed end, said viewing unit being selectively attachable to said mask so that said face-directed end contacts said first connecting rim and so that said user may view said video content of said display through said mask and said lens;
• and
• at least one magnet located on either of said mask and said viewing unit and a magnetic-attractive element located on the other of either of said mask and said viewing unit, said magnet and said magnetic-attractive element aligning with each other when said viewing unit is aligned with said open end of said mask so that said resulting pull force created by said aligned magnet and said magnetic-attractive element holds said viewing unit to said mask.
