Abstract

A system for tactile presentation of information to a pilot of an aircraft. The system comprises a pilot seat, a plurality of tactors, and a controller configured to control the plurality of tactors to tactually present the threat information to the pilot by producing one or more tactile stimuli based on situational awareness information. The tactors in the plurality of tactors are physically coupled to the pilot seat and the threat information is indicative of a threat to the aircraft. In some embodiments, at least one pressure sensor may be physically coupled to the pilot seat and the plurality of tactors may be configured to tactually present the threat information to the pilot based at least in part on data obtained by the at least one pressure sensor.

Claims

1. A method for tactile presentation of threat information to a pilot of an aircraft, the method comprising:

identifying, based on data obtained by at least one pressure sensor configured to sense an amount of pressure applied to a pilot seat in the aircraft, a plurality of tactors to use for tactually presenting the threat information to the pilot; and

tactually presenting the threat information to the pilot by controlling the identified plurality of tactors to produce one or more tactile stimuli based on situational awareness information,

wherein tactors in the plurality of tactors are physically coupled to the pilot seat in the aircraft and the threat information is indicative of a threat to the aircraft.

2. The method of claim 1, wherein controlling the identified plurality of tactors based on the situational awareness information comprises determining a level of danger to the aircraft based at least in part on the situational awareness information.

3. The method of claim 2, wherein controlling the identified plurality of tactors further comprises controlling the identified plurality of tactors to produce one or more tactile stimuli whose intensity and/or frequency depends on the determined level of danger.

4. The method of claim 1, wherein tactually presenting the threat information to the pilot comprises tactually presenting information characterizing the threat to the aircraft.

5. The method of claim 4, wherein the information characterizing the threat to the aircraft comprises information indicative of a location of the threat to the aircraft and controlling the identified plurality of tactors comprises:

controlling the identified plurality of tactors to produce the one or more tactile stimuli such that the one or more produced stimuli are indicative of the location of the threat.

6. The method of claim 1, wherein tactually presenting the threat information to the pilot comprises tactually presenting at least one action for the pilot to perform in response to the threat to the aircraft.

7. The method of claim 6, wherein the at least one action for the pilot to perform comprises maneuvering the aircraft and controlling the identified plurality of tactors comprises:

controlling the identified plurality of tactors to produce the one or more tactile stimuli such that the one or more produced stimuli are indicative of one or more maneuvers for the pilot to perform in maneuvering the aircraft.

8. The method of claim 1, wherein the threat to the aircraft is a threat of collision.

9. The method of claim 1, wherein the identified plurality of tactors is a subset of a set of tactors physically coupled to the pilot seat.

10. The method of claim 1, wherein the identified plurality of tactors is a subset of a set of tactors physically coupled to the pilot seat.

11. A system for tactile presentation of threat information to a pilot of an aircraft, the threat information indicative of a threat to the aircraft, the system comprising:

a pilot seat;

a plurality of tactors physically coupled to the pilot seat;

at least one pressure sensor configured to sense an amount of pressure applied to the pilot seat; and

a controller configured to;

identify, based on data obtained by the at least one pressure sensor, a plurality of tactors to use for tactually presenting the threat information to the pilot; and

control the identified plurality of tactors to tactually present the threat information to the pilot by producing one or more tactile stimuli based on situational awareness information.

12. The system of claim 11, wherein the threat information comprises information indicative of a location of the threat to the aircraft and wherein the controller is configured to control the identified plurality of tactors by:

controlling the identified plurality of tactors to produce the one or more tactile stimuli such that the one or more produced stimuli are indicative of the location of the threat.

13. The system of claim 11, wherein the controller is configured to control the identified plurality of tactors to tactually present the threat information to the pilot by:

controlling the identified plurality of tactors to tactually present at least one action for the pilot to take in response to the threat to the aircraft.

14. The system of claim 13, wherein the at least one action for the pilot to take comprises maneuvering the aircraft and the controller is further configured to control the plurality of tactors by:

controlling the identified plurality of tactors to produce the one or more tactile stimuli such that the one or more produced stimuli are indicative of one or more maneuvers for the pilot to perform in maneuvering the aircraft.

15. The system of claim 11, wherein the pilot seat comprises a back portion and the back portion is physically coupled to at least one tactor in the identified plurality of tactors.

16. A pilot seat in an aircraft, the pilot seat comprising:

a plurality of tactors;

a seating portion; and

at least one pressure sensor physically coupled to the seating portion, the at least one pressure sensor configured to sense an amount of pressure applied to the pilot seat;

wherein the plurality of tactors are configured to tactually present information to a pilot of the aircraft by producing one or more tactile stimuli based at least in part on data obtained by the at least one pressure sensor.

17. The pilot seat of claim 16, further comprising:

at least one seatbelt,

wherein at least a first tactor in the plurality of tactors is physically coupled to the at least one seatbelt.

18. The pilot seat of claim 16, further comprising a back support portion comprising a lumbar portion wherein:

the lumbar portion comprises at least a second tactor in the plurality of tactors.

19. The pilot seat of claim 16, wherein the plurality of tactors are configured to tactually present information to the pilot by tactually presenting threat information using only a subset of tactors in the plurality of tactors,

wherein the subset of tactors is identified based at least in part on the data obtained by the at least one pressure sensor.

20. The pilot seat of claim 16, wherein the data obtained by the at least one pressure sensor indicates an area of the pilot seat to which the pilot'"'"'s body is applying pressure.
