Binaural Sound in Visual Entertainment Media

Patent Images
1. A method to provide binaural sound to a listener in a movie theater, the method comprising:
- determining different head orientations of the listener with respect to an image of a character as the image of the character moves to different locations from one side of a movie screen to an opposite side of the movie screen while being displayed to the listener on the movie screen during a movie in the movie theater;
selecting, based on the head orientations of the listener with respect to the image of the character, head related transfer functions (HRTFs) so a voice of the character is heard to originate to the listener from the image of the character as the image of the character moves to the different locations from the one side of the movie screen to the opposite side of the movie screen;
convolving, with a digital signal processor, the voice of the character with the HRTFs; and
providing, through a wearable electronic device and to the listener, the voice of the character convolved with the HRTFs so the voice of the character localizes to the listener as originating from the image of the character as the image of the character moves to the different locations from the one side of the movie screen to the opposite side of the movie screen.

Abstract
A method provides binaural sound to a listener while the listener watches a movie so sounds from the movie localize to a location of a character in the movie. Sound is convolved with head related transfer functions (HRTFs) of the listener, and the convolved sound is provided to the listener who wears a wearable electronic device.

8. A method to provide binaural sound to a listener from a point-of-view of a character in a feature length movie while the listener watches the feature length movie, the method comprising:
-
determining an azimuth angle between the character and a source of sound in the feature length movie; selecting a head related transfer function (HRTF) that corresponds to the azimuth angle; convolving, with a digital signal processor, sound from the source of the sound with the HRTF; and providing, through a wearable electronic device and to the listener, the sound convolved with the HRTF so the listener hears the sound from the point-of-view of the character while the listener watches the feature length movie. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)

16. A method to provide binaural sound to a listener while the listener watches a movie so sounds from the movie localize behind the listener, the method comprising:
-
obtaining head related transfer functions (HRTFs) for the listener; selecting a character in the movie as an audial point-of-view of the listener; convolving, with a digital signal processor and with the HRTFs, a sound in the movie that originates from behind the character so the sound originates from behind the listener at a location that is in empty space not occupied by a tangible object; and providing, through a wearable electronic device and to the listener, the sound convolved with the HRTFs so the listener localizes the sound to originate from behind the listener at the location that is in the empty space not occupied by a tangible object while the listener watches the movie. - View Dependent Claims (17, 18, 19, 20)
