Aside from looking like you stuck your hed in a giant… somthing, this device is for virtual reality type simulations.
The still experimental 6-pound bubble-headed helmet has infrared sensors on top that detect which way the wearer’s head is moving. A projector in the back of the helmet displays corresponding images on a 16-inch screen right before the user’s eyes.
I’m sure in a few years they will have this cut down to a more manageable size.
