Abstract
In a general aspect, detected motion is localized based on channel response characteristics. In some aspects, channel responses based on wireless signals transmitted through a space between wireless communication devices are obtained. A motion detection process is executed to detect motion of an object in the space based on the channel responses, and the channel responses are analyzed to identify a location of the detected motion within one of a plurality of regions within the space.
Claims29
A motion detection method comprising:
- obtaining channel responses based on wireless signals transmitted through a space between wireless communication devices;
- executing a motion detection process to detect motion of an object in the space based on the channel responses;
- and
- by operation of one or more processors, analyzing the channel responses to identify a location of the detected motion within one of a plurality of regions within the space.
A motion detection system comprising:
- multiple wireless communication devices, each wireless communication device configured to detect motion of an object in the space based on a series of wireless signals received from other wireless communication devices;
- and
- a data processing apparatus communicably coupled to the wireless communication devices and configured to:
- obtain channel responses based on wireless signals transmitted through a space between the wireless communication devices;
- execute a motion detection process to detect motion of an object in the space based on the channel responses;
- and
- analyze the channel responses to identify a location of the motion within one of a plurality of regions within the space.
A non-transitory computer-readable medium comprising instructions which, when executed by a processor, cause the processor to:
- obtain channel responses based on wireless signals transmitted through a space between wireless communication devices;
- execute a motion detection process to detect motion of an object in the space based on the channel responses;
- and
- analyze the channel responses to identify a location of the detected motion within one of a plurality of regions within the space.
