Virtual rumble strip
First Claim
1. A virtual rumble strip for a user operating an aircraft, the virtual rumble strip comprising:
- a location positioning system for detecting a deviation in movement of the aircraft from a predetermined virtual tunnel; and
an alerting mechanism in communication with the location positioning system, wherein the alerting mechanism generates a 3-dimensional audio alert signal that warns the user of the deviation, and wherein the user may interpret the signal as originating from the direction of the deviation.

Abstract
A system and method are provided for a virtual rumble strip that uses a 3-dimensional audio alert (3-DAA) signal to warn a user operating a vehicle that the vehicle has deviated from a predetermined path. The virtual rumble strip may include a sensor that detects location data for the vehicle, and an alerting mechanism that receives the location data from the sensor. The alerting mechanism may include an audio processing unit that uses the location data and a Head-Related Transfer Function to create the 3-DAA signal. A speaker may then play the 3-DAA signal, which the user may interpret as originating from the direction of the deviation. The user may then respond to the 3-DAA signal by correcting the motion of the vehicle.

14. A method for warning a user operating an aircraft, the method comprising:
-
detecting location data for the aircraft;
determining a deviation in movement of the aircraft from a predetermined virtual tunnel using the location data;
creating a 3-dimensional audio alert signal based on the location data; and
playing the 3-dimensional audio alert signal to warn the user of the deviation, wherein the user may interpret the signal as originating from the direction of the deviation. - View Dependent Claims (15, 16, 17, 18, 19)

20. A virtual rumble strip for an aircraft, the virtual rumble strip comprising:
-
a location positioning system that detects location data specifying a deviation in movement of the aircraft from a predetermined virtual tunnel;
an audio processing unit in communication with the location positioning system, wherein the audio processing unit creates a 3-dimensional audio alert signal that appears to originate from the direction of the deviation from a Head-Related Transfer Function and the location data; and
a speaker for playing the 3-dimensional audio alert signal in the aircraft. - View Dependent Claims (21, 22, 25, 27)
