Information processing using a population of data acquisition devices
Distributed systems, controllers and methods for processing information from a plurality of devices are provided. A distributed system includes a plurality of devices distributed in an environment. Each device has at least a communication capability for interchanging information with others of the devices and/or with a communication system. Each of at least some of the devices has one or more sensors for acquiring sensor data related to the environment proximate to the device. At least one of the communication system or one or more of the devices is configured as a controller configured to: select a subset of devices from among the plurality of devices, receive information based on the acquired sensor data of the selected subset, and combine the received information from the selected subset to determine a characteristic of the environment proximate to one or more of the devices.
1. A system comprising:
a device among a plurality of acoustic devices; wherein the device is configured as a controller, wherein the controller is configured to perform operations comprising:
selecting a subset of acoustic devices from among the plurality of acoustic devices for acquiring sensor acoustic data, wherein the subset of acoustic devices are configured to interchange device information and data over a communication link;
receiving a first set of sensor acoustic data from a first acoustic device of the selected subset of acoustic devices;
receiving a second set of sensor acoustic data from a second acoustic device of the selected subset of acoustic devices; and
analyzing at least one of the first set of sensor acoustic data or the second set of sensor acoustic data or a combination of both to identify if speech is present.
2. The system according to claim 1 , wherein the operations further comprise:
analyzing the speech for a keyword.
3. The system of claim 2 , wherein the first set of sensor acoustic data and the second set of sensor acoustic data are received based on a triggering event.
4. The system of claim 3 , wherein the operations further comprise:
determining a direction of measurement of at least one device of the subset of devices.
5. The system of claim 1 , wherein the operations further comprise:
selecting the subset of devices based on geographic proximity to a user.
6. The system of claim 2 , wherein the operations further comprise:
activating a sensor based upon the keyword.
7. The system of claim 1 , wherein the operations further comprise:
generating an alert signal based upon an analysis of at least one of the first set of acoustic sensor data or the second set of acoustic data or a combination of both.
8. The system of claim 1 , wherein the operations further comprise:
analyzing at least one of the first set of acoustic sensor data or the second set of acoustic sensor data or a combination of both for animal sounds.
9. The system of claim 1 , wherein the operations further comprise:
determining the locations of each of the selected subset of acoustic devices.
10. The system of claim 2 , wherein the operations further comprise:
determining which of the selected subset of acoustic devices is the closest acoustic device to a user that uttered the keyword.
11. The system of claim 10 , where the operations further comprise:
determining a voice command from the keyword; and
sending the voice command to the closest acoustic device.
