The interactive public display device, which is situated at a first location within a facility, displays a facility map showing facility units, receives a user selection of a facility unit as a second location, and displays a route from the first location to the second location on the facility map. The mobile device also displays the facility map, displays a route from a start location to a destination location on the facility map, and updates the start location to the first location and the destination location to the second location by synchronizing with the interactive public display device. ## Claims ### Claim 1 A wayfinding system for a facility including multiple facility units, the wayfinding system comprising: an interactive public display device, situated at a first location within the facility, configured to: present a public user interface on a display of the public display device; display a facility map, showing the facility units, via the public user interface; receive a user selection of a facility unit as a second location, via the public user interface; and display a route from the first location to the second location on the facility map, via the public user interface; and a mobile wayfinding application executable by a mobile device to configure the mobile device to: present a mobile user interface on a display of the mobile device; display the facility map, via the mobile user interface; display a route from a start location to a destination location on the facility map, via the mobile user interface; and update the start location to the first location and the destination location to the second location by synchronizing with the public display device. ### Claim 2 (depends on 1) The wayfinding system of claim 1, wherein the facility is an indoor facility. ### Claim 3 (depends on 1) The wayfinding system of claim 1, wherein the public display device includes a synchronization feature configured to enable the mobile device to synchronize with the public display device. ### Claim 4 (depends on 1) The wayfinding system of claim 1, wherein the public display device is further configured to display a promotional item relating to the selected facility unit, via the public user interface; and wherein the mobile device is further configured to receive the promotional item by synchronizing with the public display device. ### Claim 5 (depends on 1) The wayfinding system of claim 1, further comprising: a backend system, wirelessly connected to the public display device and the mobile device, configured to: provide the facility map to the public display device and the mobile device; provide the route from the first location to the second location to the public display device; and provide the route from the start location to the destination location to the mobile device. ### Claim 6 (depends on 5) The wayfinding system of claim 5, wherein the public display device includes a scannable synchronization feature configured to enable the mobile device to synchronize with the public display device by scanning the synchronization feature; and wherein the mobile device includes a scanning device configured to scan the synchronization feature. ### Claim 7 (depends on 6) The wayfinding system of claim 6, wherein the synchronization feature is a quick response (QR) code or a near-field communication (NFC) tag. ### Claim 8 (depends on 6) The wayfinding system of claim 6, wherein the synchronization feature is encoded with an identifier of the public display device, and wherein the identifier uniquely identifies the public display device among multiple interactive public display devices. ### Claim 9 (depends on 8) The wayfinding system of claim 8, wherein the synchronization feature is encoded with a uniform resource locator (URL) including the identifier. ### Claim 10 (depends on 8) The wayfinding system of claim 8, wherein the backend system is further configured to store identifiers, locations, and current selection states for the multiple interactive public display devices. ### Claim 11 (depends on 8) The wayfinding system of claim 8, wherein the backend system is further configured to provide the first location and the second location to the mobile device upon receipt of the identifier from the mobile device. ### Claim 12 (depends on 11) The wayfinding system of claim 11, wherein the backend system is further configured to: store identifiers, locations, and current selection states for the multiple interactive public display devices; and use the identifier to identify the public display device among the multiple interactive public display devices, and to retrieve the location and the current selection state for the public display device, wherein the location is the first location, and the current selection state includes the user selection of the second location. ### Claim 13 (depends on 5) The wayfinding system of claim 5, further comprising: a geographical information system (GIS), hosted internally by the backend system or supplied externally to the backend system, configured to: store the facility map and associated facility metadata; and calculate the route from the first location to the second location and the route from the start location to the destination location. ### Claim 14 (depends on 5) The wayfinding system of claim 5, wherein the public display device is further configured to display a facility directory, listing the facility units, via the public user interface; wherein the mobile device is further configured to display the facility directory, via the mobile user interface; and wherein the backend system is further configured to provide the facility directory to the public display device and the mobile device. ### Claim 15 (depends on 14) The wayfinding system of claim 14, wherein the display of the public display device is a touch-screen display; and wherein the public display device is configured to receive the user selection by detecting a user touch on a facility unit on the facility map or in the facility directory. ### Claim 16 An interactive public display device for integration into a wayfinding system for a facility including multiple facility units, the public display device situated at a first location within the facility and comprising: a display; a processor configured to: present a public user interface on the display of the public display device; display a facility map, showing the facility units, via the public user interface; receive a user selection of a facility unit as a second location, via the public user interface; and display a route from the first location to the second location on the facility map, via the public user interface; and a synchronization feature configured to enable a mobile device to synchronize with the public display device, so that the mobile device is configured to display the route from the first location to the second location on the facility map, via a mobile user interface presented on a display of the mobile device. ### Claim 17 A mobile wayfinding application for integration into a wayfinding system for a facility including multiple facility units, the mobile wayfinding application embodied in a non-transitory computer-readable storage medium and executable by a processor of a mobile device to configure the mobile device to: present a mobile user interface on a display of the mobile device; display a facility map, showing the facility units, via the mobile user interface; display a route from a start location to a destination location on the facility map, via the mobile user interface; and update the start location to the first location and the destination location to the second location by synchronizing with an interactive public display device, wherein the public display device is situated at the first location within the facility, and wherein a current selection state of the public display device includes a user selection of the second location.
