Abstract
Determining a relative location of an object in an environment of a head-mountable device by performing a Wi-Fi round trip time (RTT) process to determine a location of the head-mountable device based on respective round-trip times for a plurality of access points or peer devices, using data generated by an inertial measurement unit as a basis for determining a pose of the head-mountable device, determining a location of a first object in an environment of the head-mountable device, and based at least in part on the location and pose of the head mountable device and the location of the first object, determining a relative location of the first object.
