AUDIO NAVIGATION ASSISTANCE
First Claim
1. A head-mounted computing device for providing navigation assistance in an environment via audio output, the head-mounted computing device comprising:
- one or more depth sensors for generating depth image data from the environment;
one or more visible light sensors for generating visible image data from the environment;
one or more transducers; and
a navigation module executed by a processor of the head-mounted computing device, the navigation module comprising a familiar navigation mode and an unfamiliar navigation mode, the navigation module configured to;
using the depth image data and visible image data, generate a three-dimensional mesh of at least a portion of the environment;
using the three-dimensional mesh, detect at least one feature in the environment;
when operating in the familiar navigation mode and based on detecting the feature, output a first audio navigation cue of the environment to the user via the one or more transducers; and
when operating in the unfamiliar navigation mode and based on detecting the feature, output a second audio navigation cue of the environment to the user via the one or more transducers, wherein the second audio navigation cue differs from the first audio navigation cue.

Abstract
Embodiments that relate to head-mounted computing device for providing navigation assistance via audio output are disclosed. For example, in one disclosed embodiment depth image and visible image data are used to generate a three-dimensional mesh of at least a portion of an environment. Using the mesh, at least one feature in the environment is detected. When operating in a familiar navigation mode and based on detecting the feature, a first audio navigation cue is outputted to the user. When operating in an unfamiliar navigation mode and based on detecting the feature, a second audio navigation cue is outputted to the user, where the second audio navigation cue differs from the first audio navigation cue.

11. In a head-mounted computing device, a method for providing navigation assistance to a user in an environment via audio output, the method comprising:
-
receiving depth image data from the environment; receiving visible image data from the environment; using the depth image data and visible image data, generating a three-dimensional mesh of at least a portion of the environment; using the three-dimensional mesh, detecting at least one feature in the environment; when the head-mounted computing device is operating in a familiar navigation mode and based on detecting the feature, outputting a first audio navigation cue of the environment to the user via the one or more transducers; and when the head-mounted computing device is operating in the unfamiliar navigation mode and based on detecting the feature, outputting a second audio navigation cue of the environment to the user via the one or more transducers, wherein the second audio navigation cue differs from the first audio navigation cue. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)

20. In a head-mounted computing device, a method for providing navigation assistance to a user in an environment via audio output, the method comprising:
-
receiving depth image data from the environment; receiving visible image data from the environment; using the depth image data and visible image data, generating a three-dimensional mesh of at least a portion of the environment; using the three-dimensional mesh, detecting at least one feature in the environment; when the head-mounted computing device is operating in a familiar navigation mode and based on detecting the feature, outputting a first audio navigation cue of the environment to the user via the one or more transducers; and when the head-mounted computing device is operating in the unfamiliar navigation mode and based on detecting the feature, outputting a second audio navigation cue of the environment to the user via the one or more transducers, wherein the second audio navigation cue differs from the first audio navigation cue; and outputting one or more of the first audio navigation cue and the second audio navigation cue to the user in a manner that causes the user to perceive the cue as originating at a three-dimensional location of the feature.
