Abstract
Methods and apparatus improve a user experience during telephone calls or other forms of communication in which a listener localizes electronically generated binaural sounds. The sound is convolved or processed to a location that is behind or near a source of the sound so that the listener perceives the location of the sound as originating from the source of the sound.
Claims20
A method that improves a user experience during a video call between a first user and a second user when the first user holds a handheld portable electronic device (HPED) less than one meter away from a face of the first user, the method comprising:
- displaying, on a display of the HPED and while the first user holds the HPED less than one meter away from the face of the first user, the second user engaged in the video call with the first user;
- and
- improving the user experience of the first user during the video call by convolving, with a processor, a voice of the second user with far-field head related transfer functions (HRTFs) to a location behind the HPED relative to the face of the first user while the HPED is a near-field distance from the face of the first user.
A method that improves a user experience during a telephone call between a first user and a second user, the method comprising:
- displaying, to the first user and on a display of a handheld portable electronic device (HPED), an image of the second user during the telephone call;
- and
- improving the user experience of the first user during the telephone call by convolving, with a processor, a voice of the second user with far-field head related transfer functions (HRTFs) to a location behind the HPED relative to the first user while the HPED is a near-field distance from a face of the first user.
A method that improves a user experience when a first user and a second user talk to each other in a telephone call, the method comprising:
- displaying, on a display of a handheld portable electronic device (HPED), the second user to the first user during the telephone call;
- capturing, with a camera in the HPED, a face of the first user during the telephone call;
- and
- improving the user experience of the first user during the telephone call by convolving, with a processor and with head related transfer functions (HRTFs) having a coordinate location behind the HPED, a voice of the second user so the voice of the second user localizes to the first user as binaural sound, wherein the coordinate location of the HRTFs does not occur at a location of the HPED but a location behind the HPED along a line-of-sight from the first user to the location behind the HPED.
