1. A method comprising:
determining, by a computing device, based on first image data, a primary object and one or more accessory objects;
generating, by the computing device, based on a seed function associated with audio data and the primary object, a first virtual signature;
generating, by the computing device, based on the audio data and the one or more accessory objects, a second virtual signature;
determining, by the computing device, based on second image data comprising the primary object, and the first virtual signature, a change in at least one accessory object of the one or more accessory objects;
generating, by the computing device, based on the change in the at least one accessory object, an updated second virtual signature;
determining, by the computing device, based on a difference between the second virtual signature and the updated second virtual signature, a state of the primary object; and
causing, by the computing device, output of the state of the primary object.
