Abstract
Systems and methods for managing playback devices in accordance with embodiments of the invention are illustrated. One embodiment includes a method for modifying a system that includes several devices. The method includes steps for measuring a first signal pattern for wireless signals between the several devices, measuring a second signal pattern for the wireless signals after measuring the first signal pattern between the several devices, determining an updated state of the system based on a difference between the second signal pattern and the first signal pattern, and modifying state variables of one or more devices of the playback system based on the determined updated state.
Claims20
A method for modifying a playback system comprising a plurality of playback devices, the method comprising:
- measuring a first signal pattern for wireless signals between the plurality of playback devices;
- comparing the first signal pattern to one or more baseline signal patterns for the wireless signals between the plurality of playback devices, each baseline signal pattern corresponding to a respective state of a physical space between the plurality of playback devices, wherein the respective state includes a position of at least one physical entity in the physical space;
- estimating a current state of the physical space between the plurality of playback devices based on differences between the first signal pattern and the one or more baseline signal patterns, the current state including a current position of the at least one physical entity in the physical space;
- and
- modifying at least one state variable of one or more of the plurality of playback devices based on the current state.
A method for modifying a playback system comprising a plurality of playback devices including a primary playback device and a set of one or more secondary playback devices, the method comprising:
- measuring a first signal pattern for wireless signals between the plurality of playback devices by measuring signal strengths of the wireless signals between at least one radio chain of the primary playback device and each of a plurality of radio chains on each of the one or more secondary playback devices;
- measuring a second signal pattern for the wireless signals after measuring the first signal pattern between the plurality of playback devices, wherein measuring the second signal pattern comprises measuring the signal strengths of the wireless signals between the at least one radio chain of the primary playback device and each of the plurality of radio chains on each of the one or more secondary playback devices;
- determining an updated space state based on differences between the second signal pattern and the first signal pattern;
- and
- modifying a state variable of at least one of the plurality of playback devices based on the updated space state.
