Abstract: Incidental acceleration is used to provide an entertainment experience, where incidental acceleration is defined in one sense as acceleration that is not controlled by a user, that is in many cases present because of the user's presence in a traveling vehicle, such as an airplane, train, or car. Such may be employed to significantly improve the user's traveling experience, particularly where the user is wearing virtual reality goggles or the like, because the user will be less aware of the confined nature of the vehicle, and significantly more aware of the virtual reality environment. In a specific example, for travelers with a “fear of flying” or motion sickness, such systems and methods could lead to a more pleasurable flying experience. The acceleration data can be sourced from sensors associated with the vehicle or from a local source.
