In a general aspect, a mobile wireless communication device is operated for motion sensing. In some aspects, wireless signals transmitted from a second wireless communication device through a space during a time period are received at a first wireless communication device. By operation of the first wireless communication device, channel state information is generated based on the wireless signals. Whether the first wireless communication device moved during the time period is detected. In response to detecting that the first wireless communication device moved relative to the second wireless communication device during the time period, motion sensing parameters of a motion sensing system are updated. The channel state information is processed according to the updated motion sensing parameters to detect motion of an object—other than the first wireless communication device—in the space during the time period.

Operating a mobile wireless communication device for wireless motion sensing

A system and method perform a registration such as for a surgical navigation system by fitting a plurality of anatomical points as received to a digital model and developing a map having a corresponding confidence level indicating a degree of certainty. As additional anatomical points are received, they are continually matched to the digital model and the confidence level continually updated. The confidence level is output in any form, such as a score, a color code, or other metric. The output may include a graphical representation e.g. overlaid on an image from the digital model. The output may be a heat map overlaid on the image. The heat map may indicate an overall confidence level, and/or may indicate a plurality of confidence levels at various locations on the digital model. The overlay may provide an indication as to one or more suggested probe points to increase the level.

System and method for surgical planning

In a general aspect, a motion sensing topology of a multi-access point (multi-AP) wireless communication network can be controlled. In some aspects, the multi-AP wireless communication network includes a first AP device, a second AP device, and a multi-AP controller. The multi-AP controller identifies a wireless communication topology, which includes identifying that a first client station device is associated with the first AP device. The multi-AP controller defines a motion sensing topology that is different from the wireless communication topology, and the motion sensing topology includes a wireless motion sensing link between the first client station device and the second AP device. The multi-AP controller initiates a motion sensing measurement based on the motion sensing topology, and the motion sensing measurement uses the wireless motion sensing link while the first client station device remains associated with the first AP device.
