Abstract
GPS, the most frequently used outdoor navigation system used in the contemporary world in peoples mobile phones, however, does not prove to be reliable in indoor settings. Neither do some wireless protocols such as Bluetooth and WIFI with RSSI do an effective job due to their susceptibility to physical obstacles such as walls and objects in the building. Our team came up with a solution utilizing UWB wireless communication protocol with SS-TWA to help users with an AR device, or similarly an AR application on smartphones, to navigate in indoor settings with clear graphic guidance, similar to the guiding systems already used by people in contemporary society. The map of the indoor setting and related calculations during the navigation process are all based on clouds, and we will show in detail how we implement our design. Finally, we discussed how our solution projects about indoor positioning can also be related to fields like ML, Open World and Metaverse.
