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.
Claims19
A method of using auditorily-induced vection (AIV) to provide a user with a sense of direction in a non-gravitational environment, the method comprising:
- determining a reference point within the environment;
- obtaining an auditory object associated with the user;
- determining an orientation of the user;
- projecting the auditory object based on the orientation of the user;
- providing the projected auditory object to the user to convey the user's orientation relative to the reference point;
- and
- determining 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.
An auditorily-induced vection (AIV) system for providing a user with an enhanced sense of direction in a non-gravitational environment, the AIV system comprising:
- at least one acoustic sensor configured to sense an auditory object associated with the user;
- at least one attitude sensor configured to sense an orientation of the user;
- a controller configured to:
- receive the auditory object from the at least one acoustic sensor;
- receive the orientation of the user from the at least one attitude sensor;
- project the auditory object based on the orientation of the user and a reference point;
- and
- provide the projected auditory object to earphones to convey the user's orientation relative to the reference point;
- 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.
