First of all, You do NOT want to go walking, biking or driving with your VR goggles on. Kids should in fact, NOT go biking or walking while enjoying any AR or VR universe. Safety first. But we fell in love with this picture of a girl enjoying AR, Augmented Reality. Still, we would never let our own kids bike or walk in traffic in a AR universe.
Some discomfort may occur, in the sense of motion sickness. Highly competently produced VR experiences and tours, will greatly reduce the risk of feeling queasy, as will proper introduction and gear.
