摘要： Example systems, devices, media, and methods for tracking movable objects and presenting virtual elements on a display in proximity to the movable objects. Ultra-wideband (UWB) transmitters are mounted to each movable object in an environment including at least two synchronized UWB receivers. The receivers calculate current locations of movable objects. Portable electronic devices, including eyewear devices, are paired with the receivers in a network. A localization application determines a current location of each eyewear device. A rendering application presents virtual elements on a display as an overlay relative to the current movable object location and in relative proximity to the current eyewear location. The physical environment is represented by a static mesh. A time synchronized tracking application identifies moving items that are not coupled to a UWB transmitter. The rendering application presents the virtual elements on the display in accordance with the static mesh and the moving items.
