Abstract
The present disclosure provides a mechanism to synchronously drive distributed speakers around a user based on localization outputs of ultra wideband (UWB) communication chips already existing in devices. Distances may be determined between a user device, such as a phone or wearable, and a plurality of distributed speakers or other devices. Based on an intersection point of such distances, the user's location can be identified. Such location can be used to modify how audio is played on each of the plurality of distributed speakers.
Claims20
A user device configured to be worn or carried by a user, the user device comprising:
- an ultra wideband sensor;
- a communication interface;
- and
- one or more processors in communication with the ultra wideband sensor and the communication interface, the one or more processors configured to:
- detect, using the ultra wideband sensor, a distance between the user device and each of a plurality of audio playback devices, the detecting the distance between the user device and each of the plurality of audio playback devices comprising:
- transmitting one or more signals across wide spectrum frequency to each of the plurality of audio playback devices;
- receiving a response from each of the plurality of audio playback devices;
- and
- computing, for each response received, the distance between the user device and the audio playback device;
- determine, based on the detected distances, a location of the user device;
- and
- communicate, using the communication interface, information to one or more of the plurality of audio playback devices for playing spatialized audio based on the determined location.
A method, comprising:
- detecting, using an ultra wideband sensor, a distance between a user device and each of a plurality of audio playback devices, the detecting the distance between the user device and each of the plurality of audio playback devices comprising:
- transmitting one or more signals across wide spectrum frequency to each of the plurality of audio playback devices;
- receiving a response from each of the plurality of audio playback devices;
- and
- computing, for each response received, the distance between the user device and the audio playback device;
- determining, with one or more processors based on the detected distances, a location of the user device;
- and
- communicating information to one or more of the plurality of audio playback devices for playing spatialized audio based on the determined location.
A non-transitory computer-readable medium storing instructions executable by one or more processors for performing a method of localization of a user device for audio spatialization, the method comprising:
- detecting, using an ultra wideband sensor, a distance between a user device and each of a plurality of audio playback devices, the detecting the distance between the user device and each of the plurality of audio playback devices comprising:
- transmitting one or more signals across wide spectrum frequency to each of the plurality of audio playback devices;
- receiving a response from each of the plurality of audio playback devices;
- and
- computing, for each response received, the distance between the user device and the audio playback device;
- determining, based on the detected distances, a location of the user device;
- and
- communicating information to one or more of the plurality of audio playback devices for playing spatialized audio based on the determined location.
