System to determine direction toward user

A device comprising:

• a camera;
• a microphone array;
• one or more memories storing first computer-executable instructions;
• and
• one or more processors to execute the first computer-executable instructions to:
• acquire, using the microphone array, sound data representative of a sound;
• determine, based on the sound data, first data indicative of a first set of sound direction values;
• acquire image data using the camera;
• determine, based at least in part on the image data, second data;
• determine, based on the first data and the second data, third data indicative of a direction of the sound;
• and
• operate the device based on the third data.

A method comprising:

• acquiring, using a device comprising a plurality of microphones, sound data representative of a sound;
• determining, based on the sound data, first data comprising:
• a first plurality of sound direction values, and
• a plurality of first variance values, wherein each first variance value of the plurality of the first variance values is associated with a corresponding sound direction value from the first plurality of sound direction values;
• acquiring, using a camera associated with the device, image data;
• determining, based at least in part on the image data, second data;
• and
• determining, based on the first data and the second data, third data indicative of a direction of the sound with respect to the device.
