Generating a sound localization point (SLP) where binaural sound externally localizes to a person during a telephone call
First Claim
Patent Images
1. A method executed by a handheld portable electronic device (HPED) to generate a sound localization point (SLP) in empty space where binaural sound externally localizes to a person during a telephone call, the method comprising:
- determining, with the HPED, a location of the HPED with respect to a head of the person while HPED is within 1.5 meters from the head of the person;
generating, with the HPED, the SLP in empty space where the binaural sound will externally localize during the telephone call to the person in the empty space at the location where the HPED was located; and
convolving, with a processor in the HPED and during the telephone call between the person and another person and after the HPED is removed from the location where the SLP was generated, a voice of the another person so the voice of the another person externally localizes as the binaural sound to the person in the empty space at the location where the HPED was located to generate the SLP.

Abstract
A method generates a sound localization point (SLP) where binaural sound externally localizes to a person during a telephone call. The method determines coordinates of a location of a handheld portable electronic device (HPED) with respect to the person and saves this location as the SLP. During the telephone call, a voice of another person is convolved so the voice externally localizes to the person as the binaural sound at the SLP.

8. A method executed with a handheld portable electronic device (HPED) to generate a sound localization point (SLP) where binaural sound externally localizes to a person in empty space during a telephone call, the method comprising:
-
generating, at a location of the HPED that is proximate to a head of the person, the SLP where the binaural sound will externally localize to the person in empty space during the telephone call after the HPED is removed from the location with respect to the head of the person; retrieving, with the HPED, head related transfer functions (HRTFs) that have coordinates of the SLP; and convolving, after the HPED is removed from the location with respect to the head of the person and with a processor in the HPED during the telephone call between the person and another person, a voice of the another person with the HRTFs so the voice of the another person externally localizes as the binaural sound to the person in the empty space from the SLP where the HPED was located. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A method executed with one or more electronic devices in a computer system to generate a sound localization point (SLP) where binaural sound externally localizes to a person in empty space during a telephone call, the method comprising:
-
generating, at a location of a handheld portable electronic device (HPED), the SLP where the binaural sound will externally localize to the person in the empty space during the telephone call after the HPED is removed from the location; retrieving, from a memory of the one or more electronic devices in the computer system, head related transfer functions (HRTFs) with coordinates that correspond to coordinates of the SLP; and convolving, with the one or more electronic devices in the computer system and during the telephone call between the person and another person and after the HPED is removed from the location, a voice of the another person with the HRTFs so the voice of the another person externally localizes as the binaural sound to the person in the empty space from the SLP where the HPED was previously located to generate the SLP. - View Dependent Claims (16, 17, 18, 19, 20)
