摘要： A method, an apparatus and a computer program are provided. The method includes rendering visual augmented reality content for display on a display of a hand-held electronic device, based on a location of the hand-held electronic device; estimate a location of a user of the hand-held electronic device, different from the location of the hand-held electronic device; and rendering aural augmented reality content for output to the user of the hand-held electronic device, based on the location of the user.

摘要： According to an example embodiment, a technique for spatial audio processing on basis of two or more input audio signals that represent an audio scene and at least one further input audio signal that represents at least part of the audio scene is provided, the technique including identifying a portion of interest (POI) in the audio scene; processing the two or more input audio signals into a spatial audio signal where the POI in the audio scene is suppressed; generating, on basis of the at least one further input audio signal, a complementary audio signal that represents the POI in the audio scene; and combining the complementary audio signal with the spatial audio signal to create a reconstructed spatial audio signal.

摘要： Apparatus including a processor configured to: receive an audio signal from a close microphone, wherein the audio signal is input in a spatial audio mixing, and the close microphone is associated with a first sound source; receive a beam-formed audio signal from a microphone array, wherein the beam-formed audio signal is a result of forming a beam of the microphone array directed from the microphone array towards the close microphone so as to enhance the audio signal; determine a time duration where no further sound source is active within the sound scene the first sound source; and determine a time difference, during the time duration, between the audio signal and the beam-formed audio signal to enable alignment of the audio signal and the beam-formed audio signal.

摘要： A method including determining occurrence of a virtual information region event, the virtual information region event indicating a change of information that is allocated to a virtual information region that is at least partially beyond a field of view of a head mounted display, the virtual information region having a virtual information region location that is in a direction from the field of view, causing rendering of a non-visual notification that is indicative of the direction from the field of view in response to the virtual information region event, receiving information indicative of a visual notification invocation input, determining a visual notification that is visually descriptive of at least one aspect of the virtual information region event in response to the visual notification invocation input, and causing display of the visual notification on the head mounted display is disclosed.

摘要： A method including receiving augmentation allocation property data that includes data that correlates a virtual information region with at least one surface property, receiving information indicative of at least one physical object that is in a physical environment proximate to the head mounted display, determining that the physical object has a surface that conforms with the surface property, determining environmental augmentation allocation data that includes data that correlates the virtual information region with the surface of the physical object such that the environmental augmentation allocation data designates the surface of the physical object for display of a representation of information allocated to the virtual information region, determining that at least part of the surface of the physical object is at least partially within a field of view of the head mounted display, and causing display of at least part of information that is allocated to the virtual information region.

摘要： Apparatus including a processor configured to: receive a spatial audio signal associated with a microphone array configured to provide spatial audio capture and at least one additional audio signal associated with an additional microphone, the at least one additional microphone signal having been delayed by a variable delay determined such that the audio signals are time aligned; receive a relative position between a first position associated with the microphone array and a second position associated with the additional microphone; generate at least two output audio channel signals by processing and mixing the spatial audio signal and the at least one additional audio signal based on the relative position between the first position and the second position such that the at least two output audio channel signals present an augmented audio scene.

摘要： An approach is provided for providing location information of user devices based on signal frequencies of transmitters. The positioning platform processes and/or facilitates a processing of one or more signals, from one or more transmitters, captured at one or more user devices to determine one or more frequencies of the one or more signals. Next, the positioning platform determines device location information of the one or more user devices based, at least in part, on the one or more frequencies.
