A computing device and method are provided for transmitting a relevant subset of map data, called a neighborhood, to enable mutual spatial understanding by multiple display devices around a target virtual location to display a shared hologram in the same exact location in the physical environment at the same moment in time. The computing device may comprise a processor, a memory operatively coupled to the processor, and an anchor transfer program stored in the memory and executed by the processor.

Sharing neighboring map data across devices

A first display device and method are provided for accelerating the coarse relocalization process of the first display device by generating a session-specific identifier and sending it to a second display device, which transmits the identifier to a cloud service, which returns at least a portion of a map data set corresponding to the identifier. The returned map data set is then stitched into the local map data of the first display device to create an integrated map, which is used to render one or a plurality of holograms. The first display device may comprise a processor, a memory operatively coupled to the processor, and a fingerprint program stored in the memory and executed by the processor.

Coarse relocalization using signal fingerprints

A computing device and method are provided for accelerating the coarse relocalization process of the computing device by generating a current fingerprint using signal data detected by sensors, statistically analyzing the current fingerprint for proximity to candidate fingerprints in fingerprint data to generate a ranked list, and subsequently retrieving map data corresponding to the closest matching fingerprints in the ranked list. The computing device may comprise a processor, a memory operatively coupled to the processor, and a fingerprint program stored in the memory and executed by the processor.

A computing device is provided, including a display configured to display a plurality of holograms superimposed upon a physical environment. The computing device may further comprise a processor configured to store in non-volatile memory a representation of the physical environment, including a plurality of hologram anchors indicating locations at which the holograms are displayed. The processor may store a priority level of each hologram anchor, wherein each priority level is selected from a plurality of priority levels including a high priority level and a low priority level, and wherein at least one hologram anchor has the low priority level. The processor may determine that a total size of the plurality of hologram anchors exceeds a predetermined size threshold. The processor may, for at least one hologram anchor assigned the low priority level, delete that hologram anchor from the representation of the physical environment.
