Abstract
Systems and methods for using auditorily-induced vection (AIV) to enhance a person's attitude awareness are provided herein. In at least one embodiment, an auditory object is projected based on the orientation of the person or a vehicle and the projected auditory is provided to the person. By projecting the auditory object, the attitude of the person or the vehicle can be conveyed to the person to enhance the person's attitude awareness.
Claims14
A method of using auditorily-induced vection (AIV) to provide a user with an enhanced sense of attitude, the method comprising:
- obtaining an ecological auditory object associated with a vestibular system of the user;
- determining an orientation of the user;
- determining a projection source location relative to the orientation of the user;
- projecting the ecological auditory object from the projection source location;
- and
- providing the projected ecological auditory object to the user to convey the user's attitude in a physical environment,
- wherein determining the orientation of the user includes determining an orientation vector relative to a reference vector,
- wherein the projection source location is based at least in part on the orientation vector, and
- wherein projecting the ecological auditory object includes applying a head-related transfer function (HRTF) corresponding to the projection source location to the ecological auditory object.
An auditorily-induced vection (AIV) system for providing a user with an enhanced sense of attitude, the AIV system comprising:
- at least one acoustic sensor configured to sense an ecological auditory object associated with a vestibular system of the user;
- at least one attitude sensor configured to sense an orientation of the user;
- a controller configured to:
- receive the ecological auditory object from the at least one acoustic sensor;
- receive the orientation of the user from the at least one attitude sensor;
- determine a projection source location relative to the orientation of the user;
- project the ecological auditory object from the projection source location;
- and
- provide the projected ecological auditory object to earphones to convey the user's attitude in a physical environment;
- and
- a memory device coupled to the controller, the memory device configured to store a plurality of points in space about the user's head and a head-related transfer function (HRTF) corresponding to each of the plurality of points,
- wherein in projecting the ecological auditory object the controller is further configured to select a point from the plurality of points based on the projection source location and apply the corresponding HRTF to the ecological auditory object.
