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.
Claims14
A method executed by a head mounted display (HMD) worn on a head of a user, the method comprising:
- storing, in a memory of the HMD, head-related transfer functions (HRTFs) that are personalized to the user;
- scanning, with a camera in the HMD, an image of an iris of the user;
- determining, based on the image of the iris of the user, an identity of the user;
- retrieving, from the memory in the HMD and based on the identity of the user from the image of the iris, the HRTFs that are personalized to the user;
- and
- playing, through speakers in the HMD, binaural sound processed with the HRTFs that are personalized to the user;
- sensing, with one or more sensors in the HMD, when the user is walking or running;
- and
- lowering, by the HMD, a volume of the binaural sound playing through the speakers to the user in response to the HMD sensing the user is walking or running.
A method executed by a head mounted display (HMD) worn on a head of a user, the method comprising:
- storing, in memory of the HMD, head-related transfer functions (HRTFs) that are personalized to the user;
- determining, from images of a face of the user captured with a camera in the HMD while the user wears the HMD, an identity of the user;
- retrieving, from the memory, the HRTFs that are personalized to the user in response to determining the identity of the user wearing the HMD;
- and
- playing, with speakers in the HMD while the user wears the HMD, binaural sound processed with the HRTFs that are personalized to the user, wherein the binaural sound originates along a line-of-sight that occurs behind a sound source at which the user is looking.
A head mounted display (HMD) worn on a head of a user, the HMD comprising:
- a memory that stores head-related transfer functions (HRTFs) that are personalized to the user;
- speakers that play binaural sound processed with the HRTFs that are personalized to the user;
- a sensor that senses when the user is walking;
- and
- one or more sensors that scan an image of an iris of the user while the user wears the HMD,
- wherein the HMD determines, based on the image of the iris of the user, an identity of the user and retrieves, from the memory in the HMD and based on the identity of the user from the image of the iris, the HRTFs that are personalized to the user, and processes binaural sound with the HRTFs that are personalized to the user, and
- wherein the HMD lowers a volume of the binaural sound that plays to the user through the speakers in response to the sensor sensing the user is walking.
