Abstract
Methods, apparatus and systems for providing automatic assistance based on wireless monitoring are described. In one example, a described automatic assistant system comprises: a transmitter, a receiver, a processor, and an assistant device. The transmitter is configured for transmitting a first wireless signal through a wireless multipath channel of a venue. The receiver is configured for receiving a second wireless signal through the wireless multipath channel. The second wireless signal differs from the first wireless signal due to the wireless multipath channel that is impacted by a motion of an object in the venue. The processor is configured for: obtaining a time series of channel information (TSCI) of the wireless multipath channel based on the second wireless signal, and monitoring the motion of the object in the venue based on the TSCI. The assistant device is configured for generating an assistance with respect to the object in the venue based on the monitoring.
