Title:
ワイヤレス信号の統計パラメータのグルーピングに基づく動き検出
Document Type and Number:
Japanese Patent JP7249337
Kind Code:
B2
Abstract:
In a general aspect, motion is detected based on statistical parameters of received wireless signals. In some aspects, signals are obtained. The signals are based on wireless signals transmitted through a space and received at a wireless communication device. Values of a set of statistical parameters are computed for each signal, and groupings of the statistical parameter values are identified. A motion detection process that uses the identified groupings is executed to determine whether an object moved in the space.
