Abstract:
Method, apparatus and systems for object tracking are disclosed. In one example, a disclosed method includes obtaining at least one time series of channel information (CI) of a wireless multipath channel using: a processor, a memory communicatively coupled with the processor and a set of instructions stored in the memory. The at least one time series of channel information is extracted from a wireless signal transmitted between a Type 1 heterogeneous wireless device at a first position in a venue and a Type 2 heterogeneous wireless device at a second position in the venue through the wireless multipath channel. The wireless multipath channel is impacted by a current movement of an object in the venue. The method also includes determining a spatial-temporal information of the object based on at least one of: the at least one time series of channel information, a time parameter associated with the current movement, and a past spatial-temporal information of the object. The at least one time series of channel information is preprocessed. Associated computation may be shared among the processor, the Type 1 heterogeneous wireless device and the Type 2 heterogeneous wireless device.

Claim (Index 4):
The method of  claim 1 , further comprising:\n determining at least one most recent CI each being most recent in one of the at least one time series of CI; computing at least one time series of similarity scores, each similarity score being computed based on two CI of a particular time series associated with the similarity score: the most recent CI, and a temporally adjacent CI within a time window associated with the current movement of the object; determining at least one curve, each based on a time series of similar scores; and identifying at least one feature point each associated with a curve, wherein the spatial-temporal information of the object is determined based on the at least one feature point,\n wherein the at least one feature point comprises at least one of: a local maximum, a local minimum, a first maximum, a second maximum, another maximum, a first minimum, a second minimum, another minimum, a zero-crossing, a first zero-crossing, a second zero-crossing, another zero-crossing, a point having a pre-determined relationship with a second feature point, and another feature point.
