Children love to swing. The dizzy feeling is especially fun when the world starts spinning. A feeling that today's big kids also know. But with their high-tech toys in the form of virtual reality goggles, this motion sickness is perceived as rather disturbing. At least the professionals in the circus tent on their high trapeze swings may not be scared of heights in order to bring the fascination to the audience without accidents. In any case, in the perfect computer game world, the player is one hundred percent protected against a fall, without having to expose himself to the danger of the real experience itself.
